thank you both very much for the input. i will definitely take the advice. the hydro guy we bought the hut off advises to finish the flower cycle, 3 1/2 weeks in, then tear down the hut, and they'll exchange it with the new one. i am going to take down all four sides and keep the top and bottem for the remainder. i would totally dedicate the garage to them, but the hut works out, considering my circumstances. i think i won't add any added nuts for at least 3 more weeks. not sure. the yellowing the leaves have is very depressing.
