About two years back I received a commercial orchid growing case gratis from someone that no longer was growing orchids. I have had very good results using this case and deciced to save up and I bougnt another one with more lights. They both work very well and I can't say that I really see better results with more light. The cases do get warm in the summer (mid 80's) but the plants do just fine. Are any of you growing using homemade or commercial cases? Ed
