My Growing Light Shelves

I use grow lights to start my seeds every year. I'm cheap frugal, so I decided to make my own instead of paying $100+ for a pre-made one. I bought a shelving unit, four fluorescent light fixtures, and eight grow fluorescent bulbs. I assembled the shelves and tied the light fixtures to the bottoms of the shelves with rubber coated wire. I put the lights on a timer because I can't remember to turn them on and off consistently. I've had great results with this set up for the past four years.
