Go to IKEA or somewhere similar. You can get a worthy growbox in various sizes in the kitchen area. They are all white inside. Plus the shelves can be adjusted in height in about 2cm increments so you can attatch lights to a shelf and raise or lower them instead of hanging or raise or lower the pots on a shelf if you like. If you want to save cash, go for cfl. This way you need less climate control cos not too hot, thus saving more cash. The more money you save on the box and lights, the more cash you have to spend on quality seeds and growing medium. Plus remember to budget for fans , extention cords, spare bulb or bulbs, fuses, silicone sealant and any other thing you can think of cos these little items that cos just a few dollars mount up to quite a sum.
