Hello...quick question from a novice grower....2nd grow
Have 3 autos in a 4x2 tent...approx 3 weeks old and 8 inch high...
How far should led lights be from top of plant..thankyou👍

Honestly, I keep my lights as far above my autos as I can... even when they're seedlings! It helps the plants stretch - but if they become leggy, you'll want to lower them. Normally, about 18-24" is good.
Good luck!
Depends on what light you have. But most lights are set between 45-60cm for veg at around 65% and for flower you want a high a ppfd you can. So if you have a new led some you can grow with as low as 20cm with a high co2 environment but most lights for a normal set up will be in the 25-35cm window.
Good luck.
