3. Nutrients and watering: How to pamper your plants properly
When cultivating cannabis in coconut, the right nutrition and watering are crucial for success. Unlike with soil, you have to provide all the nutrients right from the start. But don't worry, with the right tips, your coconut grow will be child's play!
The basics of coconut nutrition
Coconut is naturally low in nutrients, which gives you full control over your plants' nutrition. Use special coconut fertilizers that are tailored to the specific properties of the substrate. These usually contain more calcium and magnesium, as coconut can bind these nutrients.
A typical nutrient plan for cannabis in coconut looks like this:
- Vegetative phase: NPK ratio of about 3-1-2
- Flowering phase: NPK ratio of about 1-3-2
- Additional calcium-magnesium supplementation throughout the growth cycle
Irrigation techniques for optimal growth
Coconut has excellent water retention capacity, but it also tends to dry out. Here are some watering tips:
- Water more frequently, but in smaller amounts than you would with soil.
- Aim for 10-20% runoff each time you water to avoid salt buildup.
- Monitor the pH of the irrigation water - keep it between 5.5 and 6.5.
- The frequency of watering depends on factors such as plant size, temperature and humidity.
EC value and pH management
The EC value (Electrical Conductivity) provides information about the nutrient concentration in your solution. The following guidelines apply to cannabis in coconut:
| Growth phase | EC value (mS/cm) |
|---|---|
| Seedlings | 0.8 - 1.0 |
| Vegetative phase | 1.2 - 1.6 |
| Early flowering | 1.6 - 2.0 |
| Late flowering | 1.8 - 2.2 |
The pH affects the nutrient uptake of your plants. In coco, you should aim for a pH between 5.5 and 6.5. Check the pH of your nutrient solution and drain regularly to avoid nutrient blockages.
Special coconut techniques
A popular technique among coconut growers is "fertigation" - the combination of watering and fertilizing. You add a weak nutrient solution with each watering. This promotes even growth and prevents nutrient fluctuations.
Also experiment with "high-frequency fertigation". This involves watering several times a day with a weak nutrient solution. This method can lead to explosive growth, but requires careful monitoring.
Final tips
Watch your plants closely. They will show you if they need more or less nutrients. Start with a low dosage and increase it slowly. It is easier to correct undersupply than oversupply.
With the right nutrition and watering, you will achieve phenomenal results in your coco grow. Your plants will thank you with strong growth and rich harvests!
4. Light and climate control: optimal conditions for lush growth
Proper lighting and climate control are crucial to the success of your cannabis cultivation in coco. These factors directly affect the growth, health and ultimately the yield of your plants. Let's dive deeper and find out how to create the perfect environment for your green treasures.
Lighting: The power of photons
Modern LED grow lights are recommended for cannabis in coconut. They offer several advantages:
- Less heat generation than HPS lamps
- Energy efficiency and therefore lower electricity costs
- Customizable spectra for different growth phases
- Longer lifespan
Aim for a light intensity of 30-50 watts of real power consumption per square foot (approx. 30x30cm) of your growing space. During the flowering phase, you can even increase the intensity up to 65 watts per square foot.
Light cycles for optimal growth
Follow this lighting scheme for best results:
| Growth phase | Light rhythm |
|---|---|
| Germination & Seedlings | 18-24 hours light / 6-0 hours darkness |
| Vegetative phase | 18 hours light / 6 hours darkness |
| Flowering phase | 12 hours light / 12 hours darkness |
Temperature management: The Goldilocks zone
Cannabis in coconut thrives best in a certain temperature range:
- Vegetative phase: 20-28°C (ideally 24-26°C)
- Flowering phase: 18-26°C (ideal 22-24°C)
Make sure that the night temperature is not more than 10°C below the daytime temperature to avoid stressful situations for the plants.
Humidity: The often overlooked factor
The right humidity is crucial for healthy growth and prevents mold growth. Follow these guidelines:
- Germination & seedlings: 70-80% relative humidity (RH)
- Vegetative phase: 50-70% RH
- Early flowering: 40-50% RH
- Late flowering: 35-45% RH
A dehumidifier can be essential during the flowering phase, especially if you are growing in a humid climate.
CO2 enrichment: The turbo for your plants
Advanced growers can increase growth even further by adding CO2. With optimal lighting and nutrient supply, a CO2 concentration of 1200-1500 ppm can increase yield by up to 20%. However, note that CO2 enrichment only makes sense in a well-sealed grow box with controlled ventilation.
