The room is small. It has about 4 m square!

What is an MH, HPS and CFL? Can you tell me the full name. I have tu buy that here in Portugal, so the name is different. But with the full name I should be able to find it here. It would help if you could give me some links with those things

Thanks for you help!!! Apreciate it very much!!
Carinhas Reviewed by Carinhas on . Purple Power indoors. Good or bad idea? Hi, I'm new in this matter so I would like some help here... :) I want to grow some Purple Power indoors but I would like some opinions on it. Is it going to be ok? Will I have some nice yield? I also would like if you guys could give a small list of materials I'll have to buy to grow this plant indoors. I don't have a lot of money so just give me the basic equipment to grow a healthy plant in a small bathroom. I'm thinking on planting 4 seeds in the bathroom ;) What you think? Rating: 5
