Great friend to have Canni:thumbsup:. But if you had the stones and the space like that, im sure it no more difficult then yours, only wayyyyyyy bigger. lol So a lot of work to do in that big ass space, but he's smart to use the method with the space. If ya can let use know the dry weight if ya can.

36 Plants is a lotta plants man, but id like to grow for people. Do ya advertise or is it a worda mouth kinda thing? Im thinking ya need a few 1k's with a light mover. Man those movers are cool, you can grow more with less almost. But im not sure how it would effect plants not having the constant light on them. I guess it sounds good, but if it did work, im sure your buddy would have used it, way less electric.

Pics?
