yes it is, its working out great except i already need another :lol:
the only thing to note i guess is the trays on top run about 2-3% humidity lower than the bottom because its so cavernous in there, but its no big deal...its usually ~64% in the bottom and 61-62% up top...i could prolly solve it with an oust fan but i just cant sacrifice the room right now...im not even sure how im gonna store my boxes, right now i just got a water pillow in each and its doing the trick
