You will need to get some more lights eventually. You can get Y-socket splitters, and double your lights. You can also triple up on the Y socket splitters, so you can use one socket and have 4 bulbs. There's a sticky in the Indoor Lighting section called "El Cheapo Guide to Lighting", it'll show you what I mean. The more light, the faster growth, and the better final product.

I don't know much about that purple light, other than it's not used much by growers. Stick with the CFL's for now, it's the cheapest way to go.

Happy growing :jointsmile:
