If you're new to growing cannabis, you may not know what a SCROG is. Simply put, SCROG means "Screen of Green" and it is a grow technique that is use to achieve a higher yield.
Liquid Jade, a grower who makes YouTube videos of his garden, recently released a video showing his audience how to make and install a net for the SCROG method. He has a 4x8 grow tent and simply uses 2 big pieces of chicken wire and zip ties for his SCROG. Once the chicken wire is zip tied to the poles, he lowers the pieces so they are 18-20" from top of the grow pot. His video below shows you exactly how to make and install a SCROG.
