I have some shelves for my seedlings, 4 seedlings trays per shelf, two two-bulbs 48" fluorescent lights.
What do you think is the best way of placing the seedlings trays under the lights?
Parallel or perpendicular to the lights?
Or should I just switch them from parallel to perdpendicular once in a while (that's what I'm doing right now).
