Yeah Horseman,

The sreens where 4'x4' frames and had chicken wire in them.
Screens were 1' above the pots.
This guy vegged for a long time tho I don't remember how long, he was contstantly cutting anf trimming to get the screen filled and even cut stuff above screen to keep it even. To get shorter growth just start your 12/12 when they are about 8" above screen should finish closer to 18-24" ( which btw is what I'd probably shoot for).

I still think it's the N.Koreans screwing up the internet.

Not sure if this ever made it thru, but I was telling someone about my memerory. Long term memeory of stuff that is trivial I can remember great like things I did on the farm when I was a kid. But it is the short term memory that's a troubleing. Like waking up and saying where the hell am I? what time is it? what day? and hey who is this in the bed with me?.......and why is she dead?
