so many options when it comes to drainage. what i would do i make a table out of plywood, then make an 8" tall frame around the edge of the table. then, drill a couple of 1" holes in the plywood for drains. wrap with waterproof tarp, and use hydro table fittings to drain to waste, until the blumats are dialed in.
you could go the extra mile and grab some landscape fabric and make a rectangular smart pot to fit in frame.
as far as soil type, you could do coco or pro-mix with chem nutes and a dead rez, no prob. All organic LC's mix + guanos and shit would work really wel too.
im actually planning something like this for a 1K SDibl SOG in coco. vegging a momma right now, probably gonna do 36 cuts in a 4 x 4, or 49 in a 5 x 5. im not gonna worry about any drainage, I have a really good grasp on how the blumats work.
