Mastering the SCROG (Screen of Green) Methods: A Comprehensive Guide


In my journey as a cannabis grower, I’ve come to realize the critical importance of mastering various training techniques. Among these, the Screen of Green (Scrogging) method stands out in optimizing yields and maximizing the potential of my plant. As I delved deeper into cannabis cultivation, I discovered that Scrogging isn’t just about growing plants; it’s about sculpting an environment where each bud thrives to its fullest potential. In this article, I’m gonna share my insights into Scrogging, detailing its benefits, techniques, and practical tips for implementation. Whether you’re a novice or experienced grower, understanding Scrogging can elevate your cultivation game and unlock the true potential of your cannabis garden. Join me as we explore the transformative power of Scrogging and learn how to harness it for bountiful harvests.

What is Scrog?

Scrogging, short for “Screen of Green,” is a popular low-stress training method used by cannabis growers to increase yields and control plant size. It involves weaving and tucking the plant’s branches through a horizontal screen or net, creating an even canopy for maximum light exposure and airflow.


Benefits of Scrogging

Scrogging offers several benefits, including increased yields, better light distribution, improved airflow, and more efficient use of grow space. By controlling the plant’s height and shape, you can grow multiple plants in a smaller area, making it an excellent technique for indoor and space-limited grows.

When to Start Scrog

Scrogging during the Vegetative Stage

1. Topping and Training
During the vegetative stage, top and train your plants to encourage multiple main colas and lateral growth. Topping involves cutting off the main growing tip, which forces the plant to divert its energy into side branches, creating a bushier structure.
2. Weaving and Tucking  
As the plant grows, gently weave and tuck the branches through the openings in the scrog net, spreading them out evenly across the screen. This process should begin early in the vegetative stage and continue until the plant fills the entire net.

Scrogging during the Flowering Stage

1. Continuing to Weave and Tuck
Once your plant enters the flowering stage, continue to weave and tuck new growth through the scrog net. This ensures that all bud sites receive adequate light exposure and airflow, promoting even and dense bud development.

2. Scrog Net Adjustments
As your plant grows taller during the flowering stage, you may need to raise the scrog net or screen to accommodate the stretching. Maintain a consistent distance between the canopy and the net to prevent the buds from becoming too dense or overcrowded.

Materials Needed for Scrogging

To get started with scrogging, you’ll need a few essential items:

A scrog net or screen is a crucial component of the scrogging process. These can be purchased from grow shops or online retailers or even made at home using mesh or trellis netting. Ensure the net has holes large enough to accommodate the plant’s branches but small enough to provide support.

You’ll also need something to secure the branches to the net, such as soft plant ties or bendable wire. Avoid using anything too rigid or sharp, as it can damage the plant’s delicate branches.

Setting Up the Scrog Net

Place the scrog net or screen above the plant’s canopy, typically around 12-18 inches (30-45 cm) above the growing medium. Adjust the height as needed to accommodate the plant’s growth. Secure the net or screen in place using supports or a frame to prevent sagging.

Combining Scrogging with Other Methods


Lollipopping is a defoliation technique that involves removing the lower branches and growth to improve airflow and direct energy towards the main bud sites. Combining lollipopping with scrogging can further enhance yields and bud quality.



Selective defoliation, or the removal of fan leaves, can be used in conjunction with scrogging to improve light penetration and airflow to the bud sites. However, be cautious not to defoliate too aggressively, as it can stress the plant and hinder its growth.



The best time to start scrogging is during the early vegetative stage, when the plant is still young and pliable.


Yes, you can scrog autoflowering strains, but you’ll need to be more diligent in your timing and training, as autoflowers have a shorter vegetative phase.


Watering and feeding schedules for scrogged plants are similar to those for untrained plants, but you may need to adjust based on the increased growth and bud development.


Yes, scrogging can be combined with other training methods like topping, fimming, and lollipopping for even better results.


Maintaining good airflow and preventing overly dense growth is crucial for preventing pest and mold issues in a scrogged grow. Regular inspections and proper environmental control are also essential.



Scrogging is an effective and low-stress training technique that can significantly improve your cannabis yields and grow quality. By creating an even canopy and maximizing light exposure, scrogging encourages the development of more bud sites and denser, higher-quality buds. With proper preparation, patience, and attention to detail, even novice growers can reap the benefits of this versatile method.
