900w is really powerful. Is that just fir 1 plant? Just curious, btw what's the actual draw if that light? Like everyone else has said already start at like 24" and work toward the plant. You would never ever get 8" close. Especially with 900 Watts! The closest you should get is 18" ever. Keep your hand under that light at 8" or even 12" for a few and if your hand starts getting burnt, your plants will too. Sounds like you got a kick ass light!! Can you post some pics of it please?Yesterday I changed to a better led light. Today I am seeing some slight curling at the tips. Would it be accurate to interpret this as the light being to low? It was set at a foot from the tops of the plants and it is a 900 watt phlizon led light. To be safe while waiting to see what you guys thought I moved the light to 18”. Pics below. Thx All. I am so grateful for everyone’s input so far. I’ve learned something everyday I drop in here.
You may need to stay at 20" with that beast until you check actual draw and maybe when in flower if necessary you can drop lower, but if you don't need to, DON'T!! The most important thing to remember throughout all thsinis to listen to your lady friend and give her what she needs, you can't force a plant to be bigger that it's supposed to be before it's supposed to be. Time takes time.
