SCROG (Screen of Green)

SCROG (Screen of Green) method for cannabis

The SCROG method is an effective technique for maximizing the yield of cannabis plants by training them to form a uniform canopy. Here's a step-by-step guide to performing the SCROG method:

1. Preparation and materials

• Cannabis seeds : Choose strains suitable for SCROG, ideally those that respond well to training.
• Growing area : An indoor grow tent or a grow room with sufficient space.
• Light source : LED, HPS or CFL lamps evenly distributed throughout the grow area.
• Screen : A net with a mesh size of approximately 5 cm x 5 cm.
• Pots : Pots large enough to accommodate the plants’ root systems.
• Support elements : Poles or frames to hold the net over the plants.
• Accessories : scissors, cable ties, wire or plant ties.

2. Structure of the SCROG system

1. Attach the net : Place the net about 20-30 cm above the pots. Secure the net to the supports or frame for stability.
2. Position plants : Place the plants under the netting so they have enough space to grow. Plan for approximately one plant per 30x30 cm netting area.

3. Plant growth and training

1. Vegitative Phase : Let the plants grow in the vegetative phase until they reach the net.
2. Training shoots : Once the plants reach the net, begin guiding the main shoots through the mesh. Tie the shoots to the net with plant ties or wire.
3. Continuous training : Continuously train the plants by guiding the shoots back under the netting to create a uniform canopy. The goal is to have all the tips at the same height.

4. Transition to the flowering phase

1. Change light cycle : Change the light cycle to 12 hours of light and 12 hours of darkness to initiate the flowering phase.
2. Training buds : During the first few weeks of the flowering phase, continue to train the growing shoots to ensure that all buds receive sufficient light.

5. Care during the flowering phase

1. Remove foliage : Remove excess leaves under the mesh that do not receive direct light to improve air circulation and prevent mold growth.
2. Nutrients and Watering : Make sure to water the plants regularly and provide the right nutrients to ensure healthy growth and optimal flower development.

6. Harvest

1. Harvest Time : Determine the optimal time to harvest by examining the trichomes under a microscope. When most of the trichomes are milky and some are amber, the plant is ready to harvest.
2. Harvest : Carefully cut the plants and hang them to dry.

Tips and tricks

• Choice of strain : Indica-dominant strains are often better suited to SCROG as they grow more compactly and stretch less.
• Patience : SCROG requires patience and regular care, but the increased yield and quality of the flowers make the effort worthwhile.
• Light management : Ensure that the light is evenly distributed to avoid shadows and promote even growth.

With the SCROG method, you can maximize the yield of your cannabis plants and improve the quality of the flowers. Good luck with your grow!
