hey everyone, i went to HD yesterday looking for some vermiculite and of course they did not have it or just didn't know where it was at but anyway i was looking around and found a plastic 5 shelf rack that measures 36"W by 24" D, now if i'm correct that is perfect for a 41 qt sterilite tub for the big females. now it would need ecuaboard and cutting the legs down to size but other than that i think its perfect, oh yeah it is $44.99, lightweight and i believe it can hold up to 1000 lbs, WOW can't beat that.
