Thanks for the answers so far. I was thinking about spray foam but was worried about off gassing. Any suggestions on the brand or type to use? Any idea how much it would cost to do a 40' container? And do you frame it then spray or spray and then frame it?

I do them with 2x4 wood studs then spray foam the walls and ceiling
also add a wall with door about 18" in from the doors
4kw lighting cooled with 15k BTU ac and a santa fe classic dehumidifier
with the right strain if your are on your game it will do about 1LB/week
