If you already have the equipment, I don't think there is really any hassle. And the cost of buying could be hundreds of times more expensive in the long run.

Next time, try hanging the light in a fixed position, then safety chain it through eyebolts, bolted to a sturdy shelf. Don't move the light. Move the plants up and down.

Trust me (because we know each other so well, right)...getting seeds and getting them to germinate are the biggest hassles.
