WTF is Hydroponic? A Guide to Hydroponic Cannabis Growing

ou've probably heard the buzz about hydroponic cannabis growing and wondered, “WTF is Hydroponic?” Well, ponder no more! Hydroponics is a unique method for cultivating plants, including cannabis, without soil. Let’s dive deep and unpack all you need to know about this innovative growing technique.

What is Hydroponics?

Hydroponics involves growing plants in a water-based, nutrient-rich solution, providing a direct nutrient supply to the plant roots. This method offers complete control over growing conditions like nutrients, temperature, and light, often leading to larger yields and faster growth.

Types of Hydroponic Systems:

Various hydroponic systems exist, including the Nutrient Film Technique (NFT), Deep Water Culture (DWC), and Aeroponics, each delivering nutrients through water in distinct ways. Your choice depends on your budget, space, and growing goals.

Why Choose Hydroponics for Cannabis?

Opting for hydroponic cannabis cultivation can promise quicker growth and more substantial yields compared to more conventional soil-based growing. It minimizes concerns about soil-borne pests and diseases, albeit requiring more equipment and attention to detail.

Pros and Cons:

  • Pros:
    • Faster Growth
    • Higher Yields
    • Efficient Water Usage
    • Space-Saving
  • Cons:
    • Higher Initial Cost
    • Steeper Learning Curve
    • Regular Maintenance Needed

Getting Started:

Before diving in, familiarize yourself with essential equipment:

  • Hydroponic System: Choose a suitable system, understanding each type’s pros and cons.
  • Grow Lights: Invest in quality LED or HID grow lights to guarantee adequate lighting.
  • Nutrient Solution: Opt for a mix specially crafted for hydroponics.
  • pH and Nutrient Meters: Regularly monitor and adjust pH levels and nutrient concentrations.
  • Air and Water Pumps: Ensure uninterrupted air and water supply to the roots.

Initial Costs:

Expect the initial setup to range from $200 for a basic system to above $500 for more extensive setups.

Key Metrics to Monitor:

As you embark on this journey, keep a close eye on these metrics for optimal plant growth:

  • Nutrient Levels: Maintain the correct nutrient concentration.
  • pH Levels: Keep the pH levels within the 5.5 to 6.5 range.
  • Temperature and Humidity: Ensure a consistent temperature of 70-80°F (21-27°C) and humidity around 40-60%.
  • Light: Provide around 18 hours of light during the vegetative phase and 12 hours in the flowering phase.
  • Oxygen Levels: Sufficiently oxygenate the root zone.


Yields: Anticipate around 0.5 to 1.5 grams per watt of light, translating to 200 to 600 grams (7 to 21 ounces) with a 400-watt light.

Growth Time: Average total growth time ranges from 3 to 4 months from seed to harvest, varying based on strain and conditions.
