I started out trying to SCROG during the veg stage and after two weeks of flowering I removed the screen, it was getting hard to change the water in my bucket, but by then my plant as half-way trained. If you plan to SCROG, plan out the position and pattern your going to grow in. And make sure your plants are female...it sucks filling up your screen and finding out you have males after flowering. Im definitely going to try it again.
