Well I've cleared a spot in the garage for them the size of a tool closet. I was looking online and understand the streching of this but not sure I under stand how to stunt that. I'm go low tech and low cash on this project So I'm using some walmart special flor bulbs I'll look for the 400 w to place in my desk lamp for this. So how high above the plant do I place the light to keep from streching. Oh the seed bank says they are fims so we'l see.
