| It depends on what plants you are growing and which lighting you choose. I have a light meter ($40) and it has proved invaluable, especially after I bought my lights and needed to know how much light a certain plant was getting. It is amazing that I can move a plant just a few inches up, down, or to the side and get vastly different light readings. If using 'shop lights' the bulbs need to be as close tot he leaves as possible, but they still won't provide enough light to bloom Catts. I really don't know how I ever lived without my light meter; the best investment I even made!
