The new grow rack, lined up with its brothers, ready to go to work. The carpentry’s real rough, but it’s sturdy and tried-and-true functional. The addition of 3″ casters has created an unexpected PLUS: when the racks are rolled together, the overall light from the fluorescents spills across the shelves, giving a little more to the plants on the outer edges of the trays. This is good! There is a fairly big difference in early seedling growth from being even a couple of inches further from the lights. (Before, moving the racks around was a pain, and you need to get at both sides quite regularly for watering, rotating trays, generally checking things out. Yay for wheels!) In the end, most things even out, but you take every edge you can get and…they do add up!
