I just visited a local school and we started some seeds.When it came time to find a location for the seeds, it was a bit of a challenge. They had a closet with one small bulb which obviously would not work and they also had a window area which was ok, although a bit cold.
Ideally, they could buy a shop light and use that for both seed germination and light for the plants. Initially, I put the shop light right on top of the plastic tray top and it helps to generate heat for better germination.
Here are a few ideas from other sources on how to take a basic shop light and make it usable as a grow light for plants.
Below is the system I use with just wire shelving and 4 bulb fluorescent lights.
Using wood, you could create a way to hang the light fixture.
Below is a setup using plastic – the article is at this website.
