I have two SF4000 in a 4x4. They fit just fine. Is it too much light? just wondering if I should dim them or keep at full power. They are about 18 inches above the canopy. I set them to 60% just to be safe for now.

So far I've had them running around 70% just to be safe for now slowly creeping it up but they seem to be taking whatever I give them as long as my nutrients are on point. Your right tho it's a lot of light, first time I've considered sunglasses in a tent

Lol ya sun glasses are good
With 4 plants 4 lights the smaller one left side front is the one i experiment on with light height, just got the lights . I a gonna settle on 13 inches at this late stage only 3 or 4 weeks to go was up at 15 for first part of veg
You get a lot of benefit from light over lap
Down low bigger longer buds

Veg or flower? 900w is a lot for a 4x4.
