This year I had my first real garden, it was an awesome experience, and I don't want to give it up. So, I'm gonna TRY (operative word) to grow some stuff inside over the winter. I don't have a greenhouse or anything, but I do have a warm, rather sunny, south-facing bathroom. And I want to give lettuce, spinach, sweet and thai basil, dill, and cilantro a go.
I'm trying to keep my costs down, so if possible I don't want to have to purchase special lights or containers. So do you guys think a half gallon or 2-liter bottle would be enough root space for these plants? If I put one plant per container.
