Do you find yourself battling with hard water in your garden but aren't quite sure what makes water "hard" or "soft" in the first place? Worry not! We've got the scoop and the solution for you.

The Hard Water Conundrum in Cannabis Cultivation

What exactly is hard water? Simply put, it's water that's rich in minerals like calcium and magnesium. While these minerals don't pose health risks, they can be quite the hurdle for cannabis growers. The good news is, with the recent exit of a competitor's hard water product from the market, the spotlight is now on our Holland Secret Micro for Hard Water – your new go-to ally in the fight against hard water challenges. This guide will not only help you understand hard water but will also introduce you to how our specially formulated product can turn your growing pains into gains.

Hard Water vs Soft Water In-Home Soap Test

Understanding and Testing for Hard Water versus Soft Water

Water's hardness is determined by its mineral content, primarily calcium and magnesium. Hard water, with a PPM (parts per million) over 200, can challenge cannabis cultivation by causing nutrient lockout and inhibiting growth. Soft water, conversely, has lower levels of these minerals but might contain higher sodium, affecting plant health differently.

How to Identify Your Water Type

Annual Water Quality Reports: Your local water supplier's report can inform you about your water's hardness. If hardness levels aren't listed, contact them directly for this information.

In-Home Soap Test: Mix tap water with a few drops of pure liquid soap in a clean bottle. Hard water will produce minimal suds and appear cloudy, whereas soft water results in abundant suds and clear water at the bottom.

Hard Water Test Kits: Available at home improvement stores, these kits use test strips and a color chart for a more precise hardness measurement. Dip the strip in water, then compare its color change to the chart to determine hardness.

Water Analysis Equipment is available at BetterThanNature.

TDS Meter and Colorimeters: For immediate readings, a TDS meter can be used. Colorimeters offer a sophisticated analysis by measuring the light absorbed by water, correlating directly with mineral concentration.

Key Thresholds

Hardness Level mg/L (or PPM) Grains per Gallon (GPG) SI (mg/L)
Soft 0 - 60 0 - 3.5 0 - 60
Moderately Hard 61 - 120 3.6 - 7.0 61 - 120
Hard 121 - 180 7.1 - 10.5 121 - 180
Very Hard 181 - 240 10.6 - 14.0 181 - 240
Extremely Hard 241+ 14.1+ 241+

If your water hardness reading is 200 ppm or more, it's recommended to

Geographical Insights

An astonishing 85% of US households are affected by hard water to some degree.

  • United States: Cities like Phoenix and San Antonio report hard to very hard water levels, with Phoenix water hardness ranging from 170 to 284 mg/L and San Antonio at a staggering 305 mg/L, making these areas particularly challenging for cannabis growers.
  • Canada: Toronto and Montreal show moderately hard water with levels around 111 mg/L and 117 mg/L, respectively, indicating a need for growers in these cities to consider water quality management strategies.

Growing with Hard Water

Growing cannabis with hard water presents unique challenges due to its high mineral content, particularly calcium and magnesium, which can disrupt the nutrient uptake of plants. This condition often leads to nutrient lockout, where plants cannot absorb essential nutrients efficiently, affecting their health and growth.

When growing cannabis with hard water, it's important to adjust your nutrient mix to counteract the high levels of calcium and magnesium. One effective strategy is to reduce phosphate (PK) supplements by approximately 20%, which can help prevent nutrient lockout, ensuring plants can efficiently absorb essential nutrients.

Calmag to prevent Calcium and Magnesium Deficiencies

Holland Secret Micro Hard Water presents an excellent alternative. It seamlessly fits into your existing nutrient regimen, addressing hard water challenges with precision. This switch not only offers a solution to the discontinuation but also introduces advanced benefits for an ideally balanced growing environment, ensuring your cannabis cultivation thrives.

Growing with Very Hard Water

When Holland Secret Micro Hard Water alone doesn't bring PPM to desired levels, adding Reverse Osmosis (RO) water can help. RO water, stripped of up to 99% of salts and contaminants, needs remineralization to ensure cannabis gets necessary nutrients, as it lacks minerals essential for growth. While RO water doesn't remove certain substances like some pesticides and metals, supplementing with products like Calnesium or Organical Magic can prevent common deficiencies, making RO water a safe and effective option for cannabis cultivation.

Hard Water FAQs

Hard water contains high levels of minerals, primarily calcium and magnesium, affecting nutrient uptake in cannabis plants.

Excess minerals in hard water can lead to nutrient lockout, preventing essential nutrient absorption by the plants.

Signs include mineral buildup on fixtures, or use a TDS meter to measure water PPM. Over 200 PPM indicates hard water.

Yes, through water softeners, reverse osmosis systems, or specific nutrients like Holland Secret Micro Hard Water.

A nutrient solution designed for hard water to help cannabis plants efficiently absorb nutrients despite high mineral content.

If PPM is over 350, it's recommended to skip additional Cal-Mag supplements to avoid nutrient overload.

Consider integrating Reverse Osmosis (RO) water to further reduce mineral content for optimal plant growth.

Reducing PK supplements by about 20% can help manage nutrient balance and prevent potential toxicity or lockout.

Hard water is also known as mineralized water, calcium-rich water, lime-rich water, and magnesium-rich water, highlighting its high mineral content.
