I have a grow light station set up in the basement. It's 3 normal fluorescent lights with trays under them. The trays can all be pulled out and removed. The lights are hanging on chains so that I can raise or lower the lights as I need. The chains go up and over some dowel rods which are attached to chains which run the height of the rack system. The dowel rods connect to the runner chains by nails on the end which go through links in the chain. We did it this way so that I can move the lights wherever I want them. It sounds a lot more confusing than it really is. The sad part is that I find I still need more space to start my seeds.
You can see the top try was pulled out and is standing on end between the rack and a cabinet to the right. I had some citrus trees in there a couple of months ago and was using the middle tray and the top light. That's why the top section looks all wonky. I'll straighten everything up when I need to get my seeds started.
