is it possible to give my plants to much uvb? i keep a 75 watt grow light on them about 3 feet away 8 hrs a day. i'm planning on moving them into a terrarium with frogs and i'm afraid they won't get enough light for the light that the frogs need. the lights will be on a timer not to add alot of the plants wont be directly in ther uvb "spotlight" so to speak. i'm also putting in some pitcher plants too. the lights in the terrarium will be under flourescent 5.0 uvb lamps, any suggestions are greatly appreciated
