yes, cost is a key factor.the footprint would be something on the order of 9 x 12. in spite of doing all the construction from scratch and designing with only one surface as polycarb approx 10 x 12, i would probably have to choose between heating and cooling it, and having anything growing to put in it. the other option would be to move in with the plants and sublet my live/work space....uh, wait, that's almost what my living room is like now....

just kidding. mostly. it's another luxury problem in the end, like the potbound orchids. maybe i should try a walk-in Wardian cabinet or something...
