gobug, yes....I grow lettuce (leaf type) and spinach year around. I usually have two or three dishpan sized tubs going at any one time.
I think people are confusing grow lights with those expensive grow shelves.
What we use are some salvaged industrial shelves and chain links and shop lights with growlux bulbs being 1/2 of the bulbs in the shop lights. With hooks and link chain I can raise and lower the lights to my needs, always able to keep light close to the seedlings to avoid leggy plants. I painted the shelves a fairly attractive green. One shelving unit has only four shelves, which makes it useful for taller plants and one has five. I also have a large bench in an alcove that has several lights over it. Currently I only have the four shelf unit and the bench in use, but as we approach spring I will have both shelving units going and another shelf that I "park" flats on to rotate because one unit will be going 24 hours/ day but different plants will be under the lights.
I start all my own bedding plants and veggies, as well as enough for several friends and family members. We think of building a greenhouse, but the cost of building it and maintaining it and heating it always directs us back to the system we are using which provides wonderful plants, sunshine I need to stay sane and an overall happy environment.
