Is this a problem?
I recently purchased a 72 unit growing tray. It has 6 rows with 12 units per row. I also installed a 4ft. shop light purchased at Lowes. I started growing my tomato seeds. I just centered the light in the middle of the tray. Now that the seedlings are up and growing, the ones on the outer rows are bent towards the light. I started moving the tray every 2 hours so it would be directly over 3 rows, then switch it back to the other side after another 2 hours. My concern is that I will be growing leggy plants. I should have bought two lights, but another one wouldn't get put up for quite a while, so will have to live with what I got. Should I continue to rotate the tray position (during the week will have to rotate about every 7.5 hours), or just center the middle of the tray directly under the light? or am I worrying over nothing? I have never grown under lights before.
