Will grow on balcony. Nowhere to move:). I have led light 5x100w for 10 hours a day. In average 3-5k lux per plant. Approx 1 hour direct sunlight a day. I am growing persian cucumber, brocollini, tomato: early girl, cherry yellow hybrid, kumato, sungold, sweet 100, little napoli, mini bell pepper, radish, celantro and etc. I have no space that is why I want vertical garden. The most problem is low light. So, this is my first year I am trying. Will see how it goes
