The term "420" has become one of the most widely recognized codes in cannabis culture, symbolizing a time to consume cannabis (4:20 PM) as well as a day for celebration and advocacy (April 20th). It's a day when enthusiasts gather to celebrate the progress of cannabis reform and reflect on the work still needed to de-stigmatize and legalize the plant.
Today, "420" not only marks a time and date to enjoy cannabis but also serves as a rallying point for political activism, social gatherings, and a call for the normalization and legalization of cannabis.
710
A number used to refer to cannabis oils and concentrates. When flipped upside down, "710" spells "OIL," and July 10th has become a day to celebrate and consume cannabis concentrates.
2-AG
2-Arachidonoylglycerol (2-AG) is an endocannabinoid, a naturally occurring cannabinoid within the human body that interacts with the endocannabinoid system, similarly to how plant cannabinoids like THC and CBD do.
510 Thread
A type of threading used on vape pens and cartridges. The "510" refers to the threading pattern: 10 threads at 0.5mm each. It's become a standard in the industry, making many cartridges and batteries interchangeable.
12/12 Lighting Schedule
A lighting schedule used to induce flowering in photoperiod cannabis plants. The plants are given 12 hours of light followed by 12 hours of uninterrupted darkness each day, mimicking the natural transition from summer to fall.
60/40 Sativa-Indica Ratio
This ratio describes the genetic makeup of a hybrid cannabis strain. It indicates that the strain is composed of 60% Sativa genetics and 40% Indica genetics, affecting its growth characteristics and effects.
6/2 Lighting Schedule
An alternative lighting schedule for vegetative growth where plants receive light in blocks of 6 hours followed by 2 hours of darkness. Some growers believe this schedule may improve growth rates over a continuous 24-hour light cycle.
24/0 Lighting Schedule
A lighting schedule where plants are exposed to light 24 hours a day, which can be used during the vegetative stage to maximize growth. However, some growers prefer a short dark period for plant rest.
10-20 Rule
This rule is a guideline for germinating seeds, suggesting that the ideal temperature range for seed germination is between 10°C and 20°C.
3-Part Nutrients
A three-part nutrient system splits essential plant nutrients across three separate solutions, allowing growers to adjust and administer specific nutrient types at different stages of plant growth. This typically includes a formula for vegetative growth, another for overall plant health and micronutrients, and a third for the flowering stage. This customizable approach caters to the changing needs of the plant from seedling to harvest.
2-Part Nutrients
A two-part nutrient system simplifies plant feeding by splitting essential nutrients into two solutions, commonly referred to as "Part A" and "Part B." Part A typically contains certain macro and micro-nutrients, while Part B complements with the rest, ensuring plants receive a comprehensive, balanced diet throughout their lifecycle. This system streamlines the mixing process and is ideal for growers looking for efficiency without sacrificing plant health or yield.

Aeroponics
Aeroponics is an advanced cultivation method where plants are grown in an air or mist environment without the use of soil or an aggregate medium. The roots hang in the air and are periodically misted with a nutrient-rich solution, allowing for maximum oxygen uptake and nutrient efficiency. This method is known for promoting rapid growth rates, higher yields, and reducing the risk of soil-borne pests and diseases.
Autoflowering
Autoflowering cannabis strains are genetically designed to flower automatically after a certain period of growth, typically 2-4 weeks, regardless of light cycle changes. These strains are particularly appealing for their simplicity and speed, as they allow for multiple harvests within a single season and are generally less demanding in terms of lighting management.
Amendments
Soil or growing medium amendments are materials added to improve the medium's physical properties, nutrient balance, and water retention capabilities. Organic amendments include compost, manure, and bone meal, which slowly enrich the soil with nutrients. Inorganic amendments, such as perlite and vermiculite, improve aeration and drainage.
Anatomy
Key components include the roots, responsible for nutrient and water uptake; the stem, which supports the plant; leaves, the site of photosynthesis; and flowers, where cannabinoids and terpenes are produced. Familiarity with each part helps in diagnosing health issues and optimizing growth.
Apical Dominance
Apical dominance is a growth pattern where the main stem of the cannabis plant grows more vigorously than the side branches, leading to a taller, less bushy plant. Growers often manipulate this natural tendency through techniques like topping (cutting off the plant's top) or FIMming (pinching the top leaves), encouraging a more lateral growth to increase light exposure and yield.
Aquaponics
Aquaponics combines fish farming (aquaculture) with soilless plant cultivation (hydroponics) in a closed-loop system. Fish waste provides organic nutrients for the plants, while the plants clean and filter the water, which is recirculated back to the fish tanks. This sustainable method mimics natural ecosystems, making it efficient and environmentally friendly.
Auxins
Auxins are a group of plant hormones crucial for growth and development, influencing cell elongation, bud formation, and root development. They play a significant role in shaping the plant's architecture, including the suppression of lateral branch growth in favor of the main stem, known as apical dominance.
Alkalinity
Alkalinity in the context of cannabis cultivation refers to the water or growing medium's capacity to neutralize acids, which is crucial for maintaining a stable pH level. A proper pH level ensures that plants can effectively absorb nutrients. Most cannabis plants thrive in slightly acidic conditions (pH 5.5-6.5 for hydroponics, 6.0-7.0 for soil).
Air Pruning
Air pruning is a technique used in container gardening to encourage a healthier root system. When roots reach the edge of a breathable fabric pot, the exposed air naturally prunes them, preventing circling and promoting the growth of new feeder roots. This results in a more fibrous root structure, enhancing the plant's ability to uptake water and nutrients, leading to improved overall health and growth.

Bud
The bud refers to the flower of the cannabis plant, which is the primary site for cannabinoid and terpene production, making it the most valuable part of the plant for medicinal and recreational use. Buds are harvested, dried, and cured before consumption. They are characterized by their dense, resinous structure, rich in trichomes.
Bloom Phase
The bloom phase, or flowering stage, is when cannabis plants develop their buds. This stage is triggered by changing the light cycle to 12 hours of light and 12 hours of darkness. During this period, plants require different nutrients, primarily phosphorus and potassium, to support bud formation and development.
Botrytis
Also known as bud rot or gray mold, Botrytis is a common fungal disease that affects cannabis plants, especially during the flowering stage under high humidity conditions. It can devastate crops by rotting the buds from the inside out. Prevention involves maintaining optimal airflow, humidity, and plant health.
Beneficial Insects
A ballast is an electrical device used with HID (high-intensity discharge) lamps, such as metal halide or high-pressure sodium lights, to regulate the voltage and current supplied to the lamp. Ensuring stable operation and extending the lamp's lifespan. Digital ballasts are preferred for their efficiency and ability to adjust output levels.
Biomass
In cannabis cultivation, biomass refers to the total mass of organic material (plants or parts of plants) produced in a given area or volume. It can include both usable material, such as buds and leaves, and waste material. Biomass is often measured to evaluate yield efficiency and can be used for extraction purposes.
Buffering
Buffering refers to the process of pre-treating growing mediums (like coco coir) with calcium and magnesium to stabilize pH levels and nutrient availability. This ensures that the medium will not leach essential nutrients from the solution or plants, promoting healthier growth and development.
Brix
Brix is a measure of the sugar content in an aqueous solution and, by extension, in plant sap. In cannabis cultivation, a higher Brix level indicates a healthier plant that is more resistant to pests and diseases, as well as potentially more flavorful and potent buds due to increased nutrient density.
Broad Spectrum
Broad-spectrum lighting refers to artificial light sources that emit a wide range of wavelengths, simulating the natural sunlight spectrum. This is beneficial for cannabis growth, as different wavelengths are utilized during various growth stages, from vegetative growth to flowering.
Bract
A bract is a leaf-like structure that encases the female cannabis flower's reproductive parts. Bracts are densely coated with resin glands (trichomes) that produce high concentrations of cannabinoids and terpenes. The size and number of bracts can be an indicator of a flower's potency.

Calyx
The calyx is the protective floral structure of female cannabis plants, consisting of small, leaf-like parts that form the outer layer of the buds. It houses the reproductive organs and is where the majority of the plant’s cannabinoids and terpenes are produced. During flowering, the calyces swell and can give clues about the plant's readiness for harvest.
Cloning
Cloning involves taking cuttings from a mature cannabis plant to create genetically identical offshoots. This technique allows growers to replicate plants with desirable traits, such as potency, aroma, or yield, without starting from seeds. Clones skip the seed germination stage, providing a uniform crop that mirrors the parent plant’s characteristics.
Cannabinoids
Cannabinoids are chemical compounds found in cannabis that interact with the human body's endocannabinoid system, producing various effects. The most well-known cannabinoids are THC (tetrahydrocannabinol), responsible for the plant's psychoactive effects, and CBD (cannabidiol), known for its therapeutic benefits without inducing a high. Other cannabinoids include CBG, CBN, and THCV, each with unique properties and potential health benefits.
CO2 Enrichment
CO2 enrichment is a technique used in indoor growing to increase carbon dioxide levels in the air, enhancing photosynthesis and plant growth. Since CO2 is a critical component for photosynthesis, higher concentrations can lead to faster growth rates and potentially higher yields. However, this technique requires careful monitoring and control systems to maintain optimal levels and ensure plant health.
Curing
Curing is the process of slowly drying harvested cannabis buds in controlled conditions to enhance their flavor, aroma, and potency. Proper curing removes moisture from the buds, preventing mold and bacterial growth while allowing for the gradual breakdown of chlorophyll and the maturation of cannabinoids and terpenes. The result is a smoother, more pleasant smoking or vaping experience.
Cotyledon
Cotyledon refers to the first set of leaves that emerge from a cannabis seedling. These are not true leaves but rather part of the seed's embryo. Cotyledons play a crucial role in the early life of the plant, providing nutrients until the plant can perform photosynthesis with its true leaves. They are typically broader and differ in shape from the plant’s subsequent leaves.
Companion Planting
Companion planting is a cultivation practice that involves growing cannabis alongside other plants to benefit from natural synergies, such as pest control, improved soil health, and enhanced growth. Examples include planting basil to repel insects, marigolds to deter nematodes, and clover to fix nitrogen in the soil. This method promotes a biodiverse ecosystem that supports healthier plants.
Crossbreeding
Crossbreeding is the process of mating two different cannabis strains to combine desirable traits from both parents, such as disease resistance, yield size, flavor profile, or cannabinoid content. The resulting hybrid strain inherits characteristics from both parent strains, potentially leading to new varieties with unique attributes.
Cannabis Ruderalis
Cannabis ruderalis is a subspecies of the cannabis plant, less known than its sativa and indica counterparts. It is native to areas in Central and Eastern Europe and Russia. Ruderalis plants are small, hardy, and have an autoflowering trait, meaning they flower based on age rather than light cycles. This trait has been harnessed to create autoflowering hybrid strains.
Chlorophyll
Chlorophyll is a green pigment found in the leaves and stems of cannabis plants, crucial for photosynthesis, the process by which plants convert light into chemical energy. While chlorophyll is vital for growth, its presence in large quantities can affect the smoothness and flavor of smoked cannabis. Proper curing reduces chlorophyll in the buds, improving taste and reducing harshness.

Decarboxylation
Decarboxylation is a chemical process that activates the psychoactive and therapeutic compounds in cannabis. By applying heat, the process converts THCA and CBDA, the non-active acid forms of THC and CBD found in the raw plant, into their active forms, THC and CBD. This process is crucial for making cannabis-infused edibles, tinctures, and oils effective.
Dioecious
Cannabis is typically dioecious, meaning it has separate male and female plants. Female plants produce the resinous buds sought after by consumers and growers, while male plants produce pollen for reproduction. For most growers, especially those cultivating for flower production, identifying and removing male plants early in the growing cycle is important to prevent pollination, which leads to seeded buds.
Drip Irrigation
Drip irrigation is a water-efficient irrigation method that delivers water directly to the base of each plant through a network of tubing and emitters. This system minimizes water waste and evaporation by allowing water to drip slowly to the roots of plants, providing a controlled and precise water supply. It's especially beneficial in areas with water scarcity or for growers looking to reduce their water footprint.
Detoxification
In the context of cannabis, detoxification refers to the process of eliminating traces of cannabinoids from the body, commonly undertaken by individuals facing drug tests or wishing to take a tolerance break. Detox methods vary in effectiveness and can include hydration, exercise, and the use of detoxification products.
Damping-off
Damping-off is a term used to describe a variety of diseases that affect seedlings, causing them to rot at the stem base, wilt, and collapse. This condition is typically caused by fungal pathogens in the soil or growing medium, especially in conditions of high humidity and poor ventilation. Preventative measures include using sterile soil, proper spacing, and adequate airflow.
Dark Period
The dark period refers to the uninterrupted night phase required by cannabis plants, especially during the flowering stage. Cannabis plants are photoperiod sensitive, meaning their flowering cycle is triggered by changes in the light/dark cycle. Maintaining a consistent and uninterrupted dark period is crucial for inducing and sustaining the flowering phase in photoperiod strains.
Delta-9-Tetrahydrocannabinol (THC)
Delta-9-Tetrahydrocannabinol, commonly known as THC, is the primary psychoactive compound in cannabis that produces the "high" associated with marijuana use. THC interacts with the body's endocannabinoid system, affecting mood, perception, and cognition. Its potency and effects can vary significantly among different cannabis strains.
Dispensary
A dispensary is a legal retail outlet where cannabis products are sold to consumers. Dispensaries can vary widely in terms of the products they offer, including various strains of flower, edibles, concentrates, tinctures, and topicals. Staff at dispensaries often provide guidance to consumers to help them select products that meet their needs and preferences.
Drainage
Proper drainage is essential in cannabis cultivation to prevent waterlogging, which can lead to root rot and other moisture-related issues. Whether growing in soil or a hydroponic system, ensuring that excess water can escape from the root zone is critical for maintaining healthy plant growth and preventing nutrient imbalances.
Dry Sift
Dry sift refers to a solventless extraction method that separates trichomes (the resin glands containing cannabinoids and terpenes) from the rest of the cannabis plant material using a series of screens. The resulting product is a fine, kief-like powder that can be used as is or further processed into hash. Dry sifting is valued for preserving the natural flavors and qualities of the cannabis.

EC (Electrical Conductivity)
EC measures the electrical conductivity in a solution, which correlates to the concentration of soluble salts, or nutrients, present. In cannabis cultivation, monitoring EC levels is crucial for understanding the nutrient strength of a solution being fed to plants. Optimal EC levels ensure that plants receive the right amount of nutrients, neither too much (which can lead to nutrient burn) nor too little (leading to deficiencies).
Edibles
Edibles refer to food products infused with cannabis extracts or concentrates. They offer an alternative to smoking or vaporizing, providing effects that typically last longer and can be more intense. The onset time of edibles is slower, as THC is processed by the liver into 11-hydroxy-THC, a potent form of THC. Edibles' potency and delayed effects necessitate careful dosage management.
Endocannabinoid System (ECS)
The endocannabinoid system is a complex cell-signaling system identified in the early 1990s by researchers exploring THC. Present in all mammals, the ECS plays a role in regulating a range of functions and processes, including sleep, mood, appetite, memory, and reproduction. Cannabinoids from cannabis, such as THC and CBD, interact with the ECS, influencing its activities and potentially offering therapeutic benefits.
Entourage Effect
The entourage effect is a theory that suggests the various compounds in cannabis, including cannabinoids, terpenes, and flavonoids, work together synergistically to produce a more significant effect than any single compound alone. This concept supports the use of whole-plant extracts over isolated compounds, as the full spectrum of cannabis' components may offer enhanced therapeutic benefits.
Ebb and Flow
Ebb and Flow, also known as flood and drain, is a type of hydroponic system where plants are grown in a tray that periodically floods with nutrient solution before draining back into a reservoir. This method ensures that roots receive ample nutrients and oxygen. Ebb and Flow systems are favored for their simplicity, efficiency, and effectiveness in promoting robust plant growth.
Ethanol Extraction
Ethanol extraction is a common method used to extract cannabinoids and terpenes from the cannabis plant for use in oils, tinctures, edibles, and other products. Ethanol is a solvent that efficiently extracts a wide range of compounds, making it versatile for producing full-spectrum extracts. However, the process must be carefully managed to ensure the removal of all residual solvent from the final product.
Evapotranspiration
Evapotranspiration combines two processes: evaporation of water from soil and transpiration from plants. This process is critical in understanding the water needs of cannabis plants, as it influences irrigation practices. Monitoring evapotranspiration rates helps growers optimize water use, ensuring plants receive sufficient hydration without overwatering, thus promoting healthy growth and development.
Enzymes
In cannabis cultivation, enzymes play vital roles in plant growth and soil health. They catalyze essential biochemical reactions in the plant, facilitating nutrient uptake, photosynthesis, and defense against pathogens. In soil, enzymes help break down organic matter into nutrients that plants can absorb, enhancing soil fertility and plant health.
Early Flowering
Early flowering refers to the phase when cannabis plants begin to develop buds or flowers. This stage is critical for growers to monitor, as it signifies the transition from vegetative growth to the reproductive phase. Environmental factors, especially light cycles, trigger this stage in photoperiod plants, while autoflowering strains transition based on age.
Etiolation
Etiolation occurs when a cannabis plant grows with insufficient light, leading to stretched, weak, and pale growth as it reaches for a light source. This condition highlights the importance of proper lighting in cannabis cultivation. Etiolated plants often have reduced yields and potency, emphasizing the need for adequate and appropriate light exposure throughout the growth cycle.

Feminized Seeds
Feminized seeds are bred to contain no male chromosomes, ensuring that every plant grown from these seeds will flower as a female. Female cannabis plants produce the buds that are harvested for medical and recreational use. Using feminized seeds simplifies the growing process by eliminating the need to identify and remove male plants, which do not produce consumable flowers and can pollinate females, leading to seeded flowers.
Flowering Stage
The flowering stage is the period in the cannabis plant's life cycle when it develops buds. This stage follows the vegetative growth phase and is triggered by changes in the light cycle—typically, a switch from long days to shorter days. Indoor growers can initiate flowering by adjusting their lighting schedule to 12 hours of light and 12 hours of darkness. This stage requires careful attention to nutrient, water, and light needs to maximize bud development.
Foliar Feeding
Foliar feeding is a method of feeding plants by applying liquid fertilizer directly to their leaves instead of the soil. This technique can be an effective way to address nutrient deficiencies quickly, as the leaves can absorb nutrients more rapidly than roots. However, it's typically used as a supplementary feeding method and should be done with care to avoid leaf burn or fungal issues.
Flush
Flushing is a technique used towards the end of the flowering stage, where growers stop administering nutrients and water the plants with plain water instead. This process is believed to remove excess nutrients from the plant's system, potentially improving the taste and quality of the final bud by ensuring that the plant burns cleaner.
Full Spectrum LED Lights
Full spectrum LED lights are designed to mimic natural sunlight, providing a range of light wavelengths that cannabis plants need for photosynthesis and healthy growth throughout all stages of their life cycle. These lights are energy-efficient, produce less heat than traditional grow lights, and are considered ideal for growing high-quality cannabis indoors.
Fan Leaves
Fan leaves are the large, iconic leaves that are synonymous with the cannabis plant. While they don't produce THC themselves, they play a crucial role in photosynthesis, capturing light energy to convert it into chemical energy. Though not potent, fan leaves can still be used to make extracts or edibles.
Fungicides
Fungicides are chemical or natural substances used to kill or inhibit the growth of fungi that can cause diseases in cannabis plants. While effective in protecting plants, their use should be carefully managed, especially in flowering stages, to avoid contaminating the buds and ensuring consumer safety.
FIMming
FIMming (Fuck I Missed) is a plant training technique similar to topping, intended to increase the plant's bushiness and potential yield. By cutting a portion of the main stem, FIMming causes the plant to produce multiple new growing tips. This method is less precise than topping and can result in more varied growth patterns.
Fertigation
Fertigation is the process of delivering nutrients to plants through the irrigation system, combining fertilization and irrigation. This method allows for precise control over the amount and type of nutrients delivered, optimizing plant health and productivity. Fertigation is especially popular in hydroponic setups but can be used in soil-based cultivation as well.
Feminization
Feminization is a process used to produce feminized cannabis seeds. This involves inducing female plants to produce pollen, which is then used to pollinate other female plants. The resulting seeds are genetically female, minimizing the chances of male plants growing and ensuring that nearly all plants will produce buds.

Germination
Germination is the initial stage of a cannabis plant's life cycle, starting when a seed cracks open and sprouts its first root (the radicle) and shoot. Proper germination conditions include moisture, warmth, and darkness. This critical phase sets the foundation for a healthy plant, leading to successful cultivation.
Genotype
The genotype of a cannabis plant refers to its genetic makeup, including all its inherited traits. The genotype determines potential characteristics like growth habit, cannabinoid content, and resistance to pests and diseases. However, the actual expression of these traits (phenotype) can be influenced by environmental conditions.
Grafting
Grafting is a horticultural technique where tissues of plants are joined so they continue their growth together. In cannabis cultivation, grafting can allow a grower to produce multiple strains on a single plant or to combine different plant qualities, such as vigor or pest resistance, onto a chosen stock.
Grow Medium
The grow medium is the material in which the cannabis roots grow. Common mediums include soil, coco coir, hydroponic solutions, and aeroponic mists. The choice of medium can affect water retention, nutrient availability, and the overall health and development of the plant.
Gibberellins
Gibberellins are plant hormones that play a crucial role in various growth processes, including seed germination, stem elongation, and flowering. In cannabis cultivation, manipulating gibberellin levels can influence plant height and the timing of flowering, offering another tool for growers to manage crop development.
Ganja
Ganja is a term of Sanskrit origin, traditionally used in some cultures to refer to the cannabis plant or its flowers. In contemporary usage, it often refers specifically to cannabis buds used for smoking or other forms of consumption.
Greenhouse Growing
Greenhouse growing involves cultivating cannabis plants in a glass or plastic-enclosed structure that offers protection from the elements while taking advantage of natural sunlight. Greenhouses can extend growing seasons, control environmental conditions more efficiently than open-air cultivation, and reduce the need for artificial lighting.
Guerrilla Growing
Guerrilla growing refers to cultivating cannabis in secret, hidden outdoor locations to avoid detection and legal repercussions. This method relies on natural soil and sunlight, with growers typically choosing remote spots that are not easily accessible or visible to passersby.
Guttation
Guttation is the process by which plants exude droplets of xylem sap on the tips or edges of leaves, often seen in the early morning. While a normal physiological process, excessive guttation can indicate overwatering or poor water management in the cultivation environment.
Genetic Drift
Genetic drift in cannabis cultivation refers to the gradual change in the frequency of genetic traits in a population over time, especially in small populations or those reproduced from a limited number of parents. This can lead to a loss of genetic diversity and may impact the stability and characteristics of strains over generations.

Vegetative Stage
The phase in a cannabis plant's life cycle when it's growing in size and stature but not yet producing flowers. During this stage, the plant requires longer periods of light, typically 18 hours of light and 6 hours of darkness.
Ventilation
Proper ventilation is crucial in indoor cannabis cultivation to control temperature and humidity, provide a steady supply of CO2, and prevent the buildup of mold and mildew.
Vermiculite
A mineral used in cannabis cultivation as a soil amendment due to its ability to improve aeration and moisture retention in the growing medium.
Vertical Growing
A space-efficient growing technique where cannabis is cultivated in a vertical, stacked arrangement, allowing for more plants to be grown in a smaller footprint.
Vapor Pressure Deficit (VPD)
VPD is a measure of the difference between the amount of moisture in the air and the amount of moisture the air can hold when it's saturated. It's an important concept for understanding how well plants can take up water and nutrients.
Volatilization
The process by which a substance changes from a liquid or solid state into a vapor. In cannabis, this can refer to the release of terpenes and cannabinoids at high temperatures.
Viability
In terms of cannabis seeds, viability refers to the seed's ability to germinate and develop into a healthy plant. High viability rates are desirable for growers to ensure successful cultivation.
Virus
Viruses can infect cannabis plants, leading to symptoms like stunted growth, leaf discoloration, and reduced yields. Good hygiene practices and plant management are necessary to prevent viral infections.
Vascular System
The network of xylem and phloem within a cannabis plant that transports water, nutrients, and sugars to various parts of the plant. A healthy vascular system is essential for robust plant growth.
Variegation
A condition where a plant's leaves have areas of different colors, usually due to genetic mutations, viruses, or nutrient deficiencies. While sometimes aesthetically pleasing, it can be a sign of an underlying issue with the plant.

- Wilting
Watering Schedule
The planned frequency and amount of water given to cannabis plants. An effective watering schedule takes into account the plant's growth stage, size, and the environment to prevent both underwatering and overwatering.
Wattage
Refers to the power consumption of electric devices, like grow lights. In cannabis cultivation, knowing the wattage of lights is important for managing energy costs and providing the proper amount of light intensity for plant growth.
Wicking
A method of hydroponic cultivation where a material, such as a rope or felt, draws nutrient-rich water from a reservoir to the plants' roots through capillary action.
Weeding
The process of removing unwanted plants (weeds) that compete with cannabis for nutrients, light, and space. Weeding helps to ensure that the cannabis plants can grow without competition and stress.
Wet Trimming
A harvesting technique where the excess leaves of a cannabis plant are trimmed away while the plant is still freshly harvested and wet. This is often done to streamline the drying process and to prevent mold.
Windburn
A condition where plants exhibit signs of stress, such as curled or clawing leaves, due to excessive wind or a strong fan in an indoor grow area. Proper ventilation without direct, forceful air on the plants can prevent windburn.
White Label
Products produced by one company that are packaged and sold under another company's brand name. In cannabis, white labeling is common for edibles, concentrates, and other products.
Worm Castings
The nutrient-rich waste produced by earthworms. Worm castings are an excellent organic fertilizer for cannabis, providing a good balance of nutrients, and can improve soil structure and microbial life.
Whole Plant Extract
A type of cannabis extract where the entire plant is used in the extraction process, preserving the full spectrum of cannabinoids, terpenes, and other beneficial compounds.
Wilting
A sign of stress in cannabis plants, often due to inadequate water intake, where leaves droop and may turn yellow. Wilting can also be caused by root problems, overwatering, or diseases.

- Xanthophyll
- Xeriscaping
- Xylem
- Xerophyte
- X-Factor
Xanthophyll
Xanthophylls are yellow pigments that belong to the class of carotenoids in plants. In cannabis, these pigments can contribute to the coloration of leaves, especially in the fall when chlorophyll breaks down and allows the xanthophylls to become more visible.
Xeriscaping
Xeriscaping refers to a landscaping method designed for areas that are susceptible to drought or where water conservation is practiced. While cannabis typically requires a good amount of water, some principles of xeriscaping can be applied to reduce water usage without stressing the plants, like mulching and using drought-resistant plant varieties.
Xylem
Xylem is a type of plant tissue that transports water and nutrients from the roots to the leaves and flowers. In cannabis cultivation, maintaining healthy xylem is critical because it supports the plant’s growth by ensuring that all parts receive the necessary hydration and nutrition.
Xerophyte
A xerophyte is a plant adapted to grow in conditions with very low water availability. Cannabis isn't naturally a xerophyte, but understanding the traits of these plants can offer insights into breeding or cultivating cannabis in arid conditions.
X-Factor
The "X-Factor" in cannabis cultivation could refer to a variable in the growing environment or genetic makeup that has a significant but potentially unquantifiable impact on the quality or characteristics of the final product.
Y
- Yellowing
- Yield
- Yucca
- Yumbolt
Yellowing
This term refers to the yellowing of leaves, which can be a symptom of various issues, including nutrient deficiencies, overwatering, or a pH imbalance. Addressing the underlying cause is crucial to restoring plant health.
Yield
The amount of cannabis produced by a plant or crop. Yield can be influenced by genetics, growing conditions, cultivation techniques, and the skill of the grower. Optimizing yield is often a key objective in cannabis cultivation.
Yucca
Yucca extract is sometimes used in cannabis cultivation as a natural wetting agent to help with water penetration in soils, improving water uptake by the plant's roots.
Yumbolt
A cannabis strain known for its sedative effects, often sought after for its potential to alleviate insomnia and stress. Strains like Yumbolt are highlighted for their unique properties and genetic lineage.

- Zeolite
- Zinc (Zn)
- Zonal Germination
- Zymurgy
Zeolite
A mineral that's sometimes added to cannabis grow mediums to improve water retention and nutrient exchange. Zeolite can also help with ion-exchange and as a soil conditioner in cannabis cultivation.
Zinc (Zn)
An essential micronutrient for plant growth, zinc plays a key role in chlorophyll production, growth hormone synthesis, and enzyme systems. Zinc deficiencies can lead to stunted growth and distorted leaves.
Zonal Germination
This term isn't commonly used in cannabis cultivation, but it could refer to the practice of germinating seeds based on specific climate zones to ensure optimal growth conditions.
Zymurgy
The study of fermentation, which is tangentially related to cannabis through the fermentation of raw cannabis to produce certain types of extracts or the use of fermented plant extracts as organic fertilizers.
