I know there is no one perfect distance since setups and plants vary. But I’m curious to how do you decide how high or low to hang your LED grow lights? Do you go by plant stretch, light intensity or just iconic trial and error method?
Just wondering what works best in real growing situations.
Start with the manufacturer’s recommended height and go from there. Read about light burn symptoms and how to tell if your lights are too high. The strain you are growing makes a difference also as you stated. Some strains are a little shy and some just gobble everything you can throw at them. Bottom line, don’t stress over it.
Absolutely right about that - start with the manufacturer’s instructions.
