Lol, yes the tub is very nice for someone on a budget that has a extra bathroom, you have an exhuast fan or at least the opening to use, the white walls of the bathtub, water source, the drain for excess water runoff etc. etc.
I've decided against filling the tub with soil though because of the fact it would not work well with me wanting a perpetual grow. Need to be able to easily take plants in and out of the flower room.
I ended up with 7 females not bad, I will take some clones from them here soon. Also planing to buy two cool tubes for my 400 watters, a carbon filter and can fan then duct them all together and out the exhuast fan in the ceiling to help with odor and temps.
