Hi, I am new to the forum and have become as addicted to it as I am orchids. I have about 50 orchids and am finally going to have to move them to my basement. I have a glass double sliding door facing East. The area I want to use will be about 10 feet by 10 feet. Walls in the area to be used will be white. I grow, dens,catts, phals, oncids, epies and a few others. In May I put them outdoors and bring them in before frost in Oct. Any suggestions on scources for growing under lights would be much appreciated and any suggestions from any of you would also be appreciated.Will I need additional light scources other than that provided by the door. Good books on growing orchids are very difficult to find. Thanks, Bill
