Customize your Grow with Future Harvest’s New and Advanced Nutrient Feeding Chart Calculator

The Future Harvest Nutrient Calculator is your go-to tool for creating a precise cannabis feeding schedule. It's designed to help you determine the exact amount of Future Harvest nutrients you should mix into your water for optimal plant health and performance, whether you're following a feeding schedule for cannabis or other plants.

With its user-friendly interface, the calculator factors in growth stage, growing media, the size of your reservoir or watering can, and the duration of your crop's growth cycle. This ensures that you have a consistent cannabis feeding chart tailored to your needs.

Once you've set your preferred parameters, our calculator will provide a detailed cannabis nutrient schedule, quantifying the amount of Future Harvest nutrients you'll need. Recognizing that every strain has its unique needs, especially when it comes to a flowering chart or vegetative chart, our nutrient calculator lets you adjust the weeks of vegetative or flowering stages.

Here's a step-by-step overview of how our advanced plant nutrients chart works:

Choosing your Growing Media

Begin by selecting your preferred growing medium from the dropdown menu located at the upper left-hand side of the calculator. Future Harvest's Nutrient Calculator offers three primary mediums to choose from:

  • Soil: A traditional and widely-used medium, soil offers a natural environment for plant roots. It retains moisture well and contains organic nutrients that plants can tap into. However, nutrient management can be a bit more challenging due to the organic matter present in the soil.

  • Coco: Derived from the husk of coconuts, coco coir is a sustainable and pH-neutral medium. It boasts excellent water retention and aeration properties, ensuring roots receive ample oxygen. Coco requires more frequent watering than soil and offers a faster growth rate due to its superior air-to-water ratio.

  • Hydroponic: This water-based cultivation method excludes the use of soil. Plants grown hydroponically often exhibit faster growth and larger yields, given the direct nutrient access. However, it demands meticulous monitoring of nutrient levels and pH.

Set Your Reservoir Size

Adjacent to the medium dropdown, you'll find the 'Reservoir Size' option. Here, input the volume of water you'll be using. The adjacent dropdown allows you to toggle between gallons and litres, catering to your measurement preference.

⚠️ Reminder: Ensure that your units of measurement (gallons or litres) are correctly set before proceeding. This is crucial to ensure the accuracy of the chart values and recommendations.

Adjust the Duration of your Grow Operation

By default, the calculator sets your growth cycle to 6 weeks of vegetative growth and 8 weeks of flowering. Directly below, a dropdown menu lets you adjust these durations as per your plant's specific needs. Whether you're extending the vegetative phase or shortening the flowering period, the calculator adapts to your inputs.

Indica Dominant Strains

  • Example: Northern Lights, Blueberry, Granddaddy Purple
  • Vegetative Phase: Typically 4-6 weeks. Indicas generally have a shorter vegetative phase compared to sativas.
  • Flowering Phase: Around 7-9 weeks. Indicas flower quicker and are known for their dense buds.
Sativa Dominant Strains
  • Example: Haze, Amnesia, Jack Herer
  • Vegetative Phase: Usually 6-8 weeks. Sativas grow taller and might require a longer vegetative phase to mature fully.
  • Flowering Phase: Around 9-12 weeks. Sativas take longer to flower, but they produce airy and fluffy buds.

Hybrid Strains

  • Example: White Widow, Girl Scout Cookies, OG Kush
  • Vegetative Phase: Generally 5-7 weeks. Being a mix of indica and sativa genetics, hybrids can vary widely based on their dominant lineage.
  • Flowering Phase: Typically 8-10 weeks. The flowering time for hybrids depends on the specific strain and its genetic makeup.

Auto-flowering Strains

  • Example: Blue Cheese Auto, Critical Mass Auto, Amnesia Haze Auto
  • Vegetative Phase: Shortened to 2-4 weeks. Auto-flowering strains transition to the flowering phase based on age, not light cycles.
  • Flowering Phase: Around 5-7 weeks. These strains are bred for rapid growth and quick harvests.

    Note: While these are general guidelines, it's essential to monitor your plants and adjust the growth cycle based on their specific needs. Factors like lighting, nutrients, and growing conditions can influence the growth rate and flowering time.

    Understanding Future Harvest's Nutrient Lines in the Calculator

    The Future Harvest Nutrient Calculator is akin to a dynamically reactive feed schedule, offering a more interactive and tailored experience compared to the static schedules you might be familiar with on our downloads page. Each of the three specialized nutrient lines is designed to cater to varied growing needs, ensuring precision and adaptability for every grower.

    It's crucial to note that these base nutrients are mandatory for the grow schedule, and they cannot be excluded from the nutrient solution. Additionally, they must be mixed in the chronological order they appear in the nutrient calculator chart.

    For an in-depth exploration of our products, we've crafted detailed guides on Future Harvest's Additives and Base Nutrients.

    Holland Secret / Liquid Line

    is one of Future Harvest's flagship nutrient lines, meticulously designed to cater to a wide range of growing needs. This line is renowned for its versatility, making it suitable for both novice and experienced growers.

    Base Nutrients: The foundation of the Holland Secret Line revolves around its core base nutrients, which are essential for establishing a strong and healthy growth foundation for your plants. These include:

      Optimal Nutrient Concentrations - Deciphering PPM Scales

      Towards the lower section of the chart, you'll discover recommended nutrient concentration ranges, measured in parts per million (PPM). PPM is a crucial metric that quantifies the nutrient levels in your water, guiding you towards an ideal nutrient balance for your plants. These recommended ranges are essential week by week guidelines to ensure your crops receive the right nourishment.

      It's worth noting that all our PPM recommendations are based on the 500 PPM scale rather than the 700 PPM scale, a common reference point in hydroponics. To confirm these values using an electrical conductivity (EC) meter, follow this simple conversion: multiply the provided PPM values by 2, then divide the result by 1000.

      By adhering to these PPM ranges and understanding the scale used, you can fine-tune your nutrient solution precisely to your plants' requirements, promoting healthy growth and robust yields. Monitoring PPM levels in your water is an essential aspect of successful cultivation, ensuring your plants receive the optimal nutrient concentrations they need.

      Considerations and Monitoring

      • Some nutrients may be needed more during specific growth stages. Depending on your specific circumstances, you can adjust the recommendations provided by the calculator according to crop response.
      • Regularly monitor your plants' health and growth to ensure they are receiving the appropriate nutrients. Adjustments may be necessary throughout the growing season.
      • Maintain records of your nutrient applications and plant growth to track progress and make informed decisions in subsequent growing seasons.

      This comprehensive guide empowers you to navigate the Future Harvest Nutrient Calculator effectively, helping you optimize your plant growth and yield. Whether you're a novice or an experienced grower, our nutrient calculator, coupled with the versatility of Future Harvest's nutrient lines, ensures a tailor-made approach to plant cultivation for successful and rewarding results.
