I had a routine, watering each day before I went to work and raising the lights as the plants grew a little higher. It is important to keep the lights low in the beginning, almost down to the soil, so that they stay short and fat, not tall and spindly.
Well, guess what, I have developed a new passion for wanting to grow seeds again, but in a more high tech manner. While teaching, I used a tiered plant growing system which worked very well with the trays and timer and the ability to move the trays up and down - no chains.
This would probably be the most practical for the space I have.
I think this will be my after Christmas present because they are quite expensive. Stay tuned, Gardener's Supply has free shipping so this may be my choice. I just don't know whether to order the one, two or three tier system!
