Here are some radish seedlings started inside the shed. They were out of direct light until they came up. Then, they were moved under fluorescent bulbs about 2-inches away. Notice that I plant seeds in slices of paper towel and bathroom tissue rolls. That way, the seeds stay in the center of the planting area instead of drifting off to the sides where they are difficult to prick out for transplanting.
Notice the reflective material on the back wall. It bounces the light back onto seedlings.
This plant is a salad green that I picked up in Germany last fall. It has to stay inside most of the time but is happiest on the days that are above 50 so it can spend hours outside in the wind and sun.
It's already 65-F here, so I'm headed out to sun bathe the seedlings and plant more seeds!
