I bought this: 2- 25 watt Compact Floro Grow Light CF 6400K CFL = 200 - eBay (item 120513935861 end time Jun-03-10 14:52:41 PDT) How do I mount the thing? It's got that little triangle shaped handle but not sure what to do with it. Only growing inside for 2 weeks till my plants grow a couple inches then moving outside. I will be putting seeds in rapid rooter tray. So any ideas how to mount it? And how close should it be to tray?
