when I worked at Lowe's , I used to get for free, very similar racks that you see the fall and spring bulbs displayed on in the garden center. It's the same technology, but they are usually black and only about 4' tall. I had them in my greenhouse and they were perfect.( there they are , in my profile pic!) ...I can't tell you how painful it was to actually BUY something like this!!!
My house is like a cave and the only light I get is at this sliding glass door for a few hours a day in the afternoon. Hopefully it will keep everyone sort of happy for the week that they will be inside. I really do need to win the lottery!
