Well, I had to build the GH, and I had the room to do so. It has costed a little more than I first thought, but I think its worth it. Wife doesn't of course, but she is not the orchid grower either. Its only a 12 x 12 and made from wood PVC and plastic sheeting. Its a home made job but does the trick and works great. I just hope the plastic lasts a little while I don't feel like redoing it this soon. When I do redo it though I will be boxxing out the sides and taking down the PVC pipes. I'm not fond of the rounded sides and waisted space. GL with the GH.
