nice looking grow!!!!! those plants look really healthy!

just my 2 cents:
you could increase yeild with smaller holes in the "screen" i use 1or 1 1/2inch screen in my 2'x2' 150hps and 4 42cfl scrog and i usually get at least a qp. with a 250 you could probaly increase a by few oz even with only the 1' depth. you won't believe how much easier it is to train with a small screen! i started scroggin' with like 2 1/2 inch screen and when i switched to the smaller one i was amazed at the difference. you can get alot more exact placement of the budsites. expert scrogger's boast 2.4oz per square foot of screen!!!!!

btw, i'm no expert.
