Hello Dawg. New to growing. Trying a 2nd grow. I was injured at work and busted up pretty good. My disability is very painful. I looked and looked but haven't been able to find what Scrog means. Your help would be greatly appreciated. I am using an Advance Dimond series 100 at this time. Thank you for your very informative post. And, I was at a concert in Florida at the Gulf Stream Race track in 1967. The lead act was Jimi Hendricks. But it had many bands playing with Jimi the last act. But, the first act was the first public appearance of Frank Zappa and the Mothers Of Invention. It was a two day event, and I went to the second day. The day was one I treasure with many famous groups playing. The same promoter, put on WoodStock in 1969. Thanks for sharing you knowledge.
