My whole batch of heirloom tomato seedlings got leggy under my new grow light
I set up a 150 watt LED panel in my basement for my Brandywine starts, but I think I hung it a foot too high. They all stretched toward it and got super weak stems after about ten days. What's a good rule for hanging height with LEDs for veggies?

Honestly used to think you could just eyeball the height with LEDs. Then I killed a whole tray of peppers the same way. The general rule that finally worked for me is to start with the light about 6 to 8 inches above the seedlings, and then you have to raise it as they grow. Those weak stems are such a pain to fix.

Measure from your plants, not the ceiling. I keep my LED about a hand's width above the seedlings (like 4-6 inches) and check it every couple days. If it feels warm on your hand at leaf level, it's probably too close.
