Personally, I would frame walls (build walls from 2x4's) and work from there. Then you could insulate the walls. So, going from inside of the growroom to outside you would have plywood, framed wall with insulation, drywall.

If you aren't a very good carpenter, use steel studs & track. You can fuck up with that stuff all day long and all you have to do is revese your drill motor to correct your mistakes.

Before you do any framing, decide what you want to do about a/c because you will probably need a hole for an a/c unit, or for a vent, built into the wall.
