anything

Guys, I know there's a lot of information out there about soil and if I do a google search something should come up, right? Well I did that and just couldn't find or get a direct answer and It's been four, five years since I last grew and I'm getting back into it. The issue is I always did...

The remaining space would be used for break room, restrooms, cloning and mother (do commercial ops use mothers or just take clones from clippings?) rooms , supplies, entrance, trimming/drying room... Am I missing any key pieces to the grow op as far as floor plan? The goal would be to harvest...
