Casey Jones & Sour Grape - Vertical Scrog - 2 DWC

I have 1 Casey Jones (trainwreck x sour diesel) and 1 Sour Grape (purple elephant x sour diesel) clones growing in rockwool. They are already rooted and sittng under a 400w MH in a homemade vertical cool-tube set up. There are separate intakes + exhausts for the room and the light. The screens are 4 feet x 4.5 feet. The squares are 2 inch x 2 inch. It is 'stucco backer' bought at Home Deopt (diy). I pretty much made everything in the closet... or put it together at least. I'm planning on vegging the for about 8 weeks, or until the screens are full. I will use Humboldt County's Own - BushMaster to get the growth to stop at that point, and I will switch to 12/12 lighting. The flower time should be something like 10 weeks on the Sour Grape and maybe 11 weeks on the Casey Jones. I'll be harvesting by checking trichomes no matter what.
