@3N1GM4 If you've ever done drywall, this stuff is a walk in the park. There's a few guys here that use it, let me see if I can dig up a thread that has it.
I would frame out the grow area as if building an additional room minus doing it to code specifically, meaning this. (locally) Code dictates exterior walls must be framed out with 2x6 at 16" on center. Interior walls framed out with 2x4 at 18" on center if a load bearing wall and 24" on center if not load bearing.
So for a grow room I would probably frame out at 24" on center with 2x4 for the walls and 2x6 for the rafters. Then I would run conduit, setting up plugs for lights, fans, (de)humidifers, ac, etc. Then just skin the walls as if you were hanging drywall, tape the seams with aluminum ducting tape and hang everything as normal. This way you can actually build out a room within a room and not fall into that category of growers that screws up rentals. If you do it right, when you tear down you'll leave no trace you were ever there and no need to paint or clean excessively as everything would have been contained in the build out.
