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:
bigtopsfinn Reviewed by bigtopsfinn on . noob.need to know about lighting. I am planning on growing in a closet about 3.5ft deep and 2.5 feet wide. I have 3 clamp on lights with , three - 6,500 k (daylight) CFL`s. They are extremely bright and they seem sufficient for the life of the plant but I do not know what colors I should mix in, and at what time druing the plant`s life? Any suggestions would be appreciated. Rating: 5
