I'm with bts on this bro.I have a scrog journal goin now, and I can tell you that everyday is a learning experience.The general rule(from what I've read) is to wait until the screen is 60% full.But I believe the author was generalizing for simplicity sake.Strain plays a huge role in determining these things.Sativas-Indicas-hybrids.Is it a reportedly lanky or bushy strain? But ultimately, with an extreme form of lst like scrog, it seems to be more trial and error than anything else.Your screen looks great tho, keep up the good work:thumbsup:
