The temp of my entire room stays decently warm seeing as how it's so cold out. I'm sure of the exact temp, but I never get cold. Lol.
As for the lights you were looking for, you have to buy the setup for 48" fluorescent tube lights. There's a huge selection of 48" lights at wal mart. The setup holding two lights was $10. Then you buy the plant lights. They're $5 a piece.
It appears they don't have them online, but next trip to Wal Mart, go to the bulb section. You can get both items from that one isle. It's worth it. I was amazed that the light system was a total of $20 and it's doesn't use much electricity.
I can tell you what the problem was with my plant, btw. I transplanted it late. When I transplanted, you could see what seemed to be miles of roots wrapped around and around the cup. The plant didn't even grow for a full week. However, after transplanting yesterday, I've already noticed some good changes. I know, it was a dumb mistake, but it's my first time even making it this far.
