My other light arrived today that I ordered for my spider plant in the bedroom. I think the light may be slightly over kill for the plant but it also means I can have a few more plants in the bedroom as the light is pretty strong and still lights up the entire room even though the light is above the spider plant. I wont need it on all the time, I will have it on for 6 hours a day and the rest of the time it will be the natural dull light. 6 hours a day of bright light should be fine for the spider plant.
