Hydroponics: Floating DWC-SCROG for optimum yield
Learn how to combine the DWC system with a SCROG net to maximize yield in hydroponics through even light distribution and plant support.
Introduction
The DWC floating SCROG is an effective technique to maximize the yield of your cannabis plants in a Deep Water Culture (DWC) system. By placing a SCROG net over the reservoir, you can distribute the shoots evenly and achieve optimal light penetration.
Preparation
SCROG frame
- Material**: Use a sturdy PVC or metal frame placed over your DWC reservoir.
- Mesh size: The net should have rectangular mesh of about 5x5 cm to guide the shoots precisely.
Positioning
- Height: Install the SCROG net about 20-30 cm above the plant roots. This allows the shoots to spread horizontally before growing upwards.
Implementation
Guide shoots
- Early vegetation phase: In the early vegetation phase, start guiding the shoots through the mesh of the net. This promotes horizontal growth.
- Even distribution: Make sure that each shoot has enough space to receive light.
Light management
- Light source: Use strong LED lamps to ensure even lighting. The distance between lamp and mesh should be about 30-45 cm.
Nutrient management
- pH value**: Keep the pH value of the water between 5.5 and 6.0.
- EC value**: Check the EC value regularly to ensure an optimal nutrient supply.
Care and maintenance
- Check shoots regularly**: Check growth regularly and ensure that all shoots are fed through the net.
- Remove leaves: Remove excess foliage to improve air circulation and light penetration.
Advantages of the DWC-SCROG
- Optimal light utilization: Uniform light distribution over the entire plant field.
- Increased yields: Maximization of flower production through controlled growth.
Conclusion
The floating DWC-SCROG is a challenging but rewarding technique for hydroponic growers who are willing to invest in the finer points of plant care. With patience and care, this method leads to impressive yields and improved flower quality.
Pro Tips
- Start guiding the shoots early.
- Keep the SCROG net stable and well secured.
- Monitor pH and EC values regularly.
- Use high-quality LED lighting.
- Care for the shoots regularly for optimum results.
Frequently Asked Questions
What is DWC, and how does it work in cannabis cultivation?
DWC stands for Deep Water Culture, a hydroponic system in which the plants' roots float in a nutrient-rich, oxygenated solution. This enables rapid growth and high yields, as the plants have direct access to water and nutrients.
How does SCROG training work in the DWC system?
SCROG, or Screen of Green, is a technique in which a net is stretched over the plants to control their growth and optimize light distribution. In the DWC system, this promotes uniform plant development and maximizes yield.
What are the benefits of combining DWC and SCROG?
The combination of DWC and SCROG maximizes yield by making efficient use of available light and promotes uniform plant growth. It also allows for better air circulation and reduces the risk of mold and disease.
