And one more thing. I know people rock 600 watt HPS bulbs in 3x3 tents. And maybe they have it down somehow. But honestly I just don’t see the point. I think if I had kept it dimmed to 450 watts the whole time I would have had 1,000 par with plenty of distance for spread, and less heat issues. 600 watts higher up to get close to 1,000 par would not boost the canopy spread by enough to justify the excess wattage, in my experience, not in a 3x3 anyways.
I studied up on what people claimed they do with 600 watts in 3x3 tents and I think either A) they were frying their plants like I did or B) lying about the distance they had it hanging for some dumbass reason.
