We would like to grow some herbs over the winter. I've been doing a little digging around and I know I can use one of those little greenhouses, but I have horrible lighting in the house. I don't have any windows facing South. So I could do the grow light thing, but wanted to see if there were any recommendations. I don't want to waste my money, and I've heard that I can use florescent lights for this, but it's something like 14 hours to give 5 hours of "sunlight." I like the idea of a single piece unit like the AeroGarden, but that thing is almost $200. Definately not worth that. Anyone ever seen a homemade type of system like this? Any good web sites around for this type of growing?
