If it doesn't fit, make it fit... At 10 inches, these planters are just a bit too wide to slide into an Ivar shelf from the narrow side. By heating the edge with a hot-air dryer, you can make it slightly thinner. The grow lights’ control system can only handle very simple programs. I’d rather control them via home automation and a smart outlet. This works if you hold down the power button continuously: then the light turns on as soon as the power is switched on. By the way, I’m growing lamb’s lettuce here. Last year, it only sprouted in one of several outdoor beds, but now it’s coming up very evenly in the seedling tray.
