I got several grow LED panels off of ebay a while back and did some experiments, it was just enough light for plants to grow, barely, but they never bloomed
A lot has happened over the last few months!!! Time flies! I have some picture of the orchids coming. They have all adjusted fine to the lights. I originally bought the panels through a wholesaler. The Glowpanel is what i have been using now and they are nice. The light intensity reads right around were a 70-150w MH should be. There is not as much of a spread in the light but it is just as intense. Reflective boxes should fix most of the coverage. There is heat coming off the panels but not much. During the summer now my basement gets kinda hot anyways. I have several orchids blooming that never did before! I am excited and can't wait to post some pictures. Home renovation take priority right now...
