The Fundamentals of Cannabis Fertilization
The science behind cannabis growth starts with the fertilization which is a critical aspect of a successful marijuana cultivation. Providing the right nutrients at each growth stage ensures healthy plants and bountiful yields. Below, we offer a detailed insight:
Nutrient Basics
Macronutrients are essential for cannabis growth:
Nitrogen
- Promotes foliage growth.
Phosphorus
- Supports root and flower development.
Potassium
- Enhances overall plant health.
Micronutrients, such as calcium, magnesium, and iron, are necessary in smaller amounts.
pH Levels
Cannabis thrives in slightly acidic conditions:
- Soil pH range: 6.0 to 6.5.
- Hydroponic systems pH range: 5.5 to 6.5.
Growth Phases
Vegetative Stage
- High nitrogen content for foliage growth and trichome development.
Flowering Stage
- Increased phosphorus and potassium, reduced nitrogen.
Organic vs. Synthetic Fertilizers
Organic
Derived from natural sources (compost, worms, bat guano).
Synthetic
Man-made, precise nutrient formulations.
Cannabis Cultivation Techniques
Low Stress Training (LST) vs. High Stress Training (HST)
LST
Gentle shaping by bending stems to expose more bud sites.
HST
Aggressive techniques (topping, super cropping) to reshape the plant.
Sea of Green (SOG) Technique
Ideal for limited spaces.
Grow many small plants for maximum yield per square foot.
Screen of Green (SCROG) Method
Use screens to control canopy height and light exposure.
Encourages even bud development.
Super Cropping
- Deliberate stem injuries for thicker growth.
- Boosts resilience and encourages multiple colas.
Greenhouses
- Controlled environment with natural light.
- Balances indoor and outdoor benefits.
Topping and Fimming
Topping
- Removing the top of the main stem to encourage lateral growth.
Fimming
- Delicate pruning to create more colas.
Deep Water Culture (DWC) Hydroponics
- Plants grow directly in nutrient-rich water.
- Efficient nutrient uptake.
Remember, each technique has its pros and cons, so choose based on your experience level and desired results.
