i use around 140w in a 2x2.5' tent. Have used as high as 45 per square but seemed to cause problems in flower.

What problems and what have your yelids been

yeah thats getting up there......... Some plants might be able to handle it. Cactus. Tumbleweed. Things of that nature. Marijuana might struggle. And if your air temps are 83 your canopy is going to be closer to 90. Maybe if you run co2 and all the other bells and whistles.

I had leaf twisting and burning at 180w.
An average of 150w gets me around 200g's of dried goods

In my tent.. The plants seem to take more watts in veg than they can in mid to late flower

Boatguy what light do you use?

I had a homemade cob rig, similar to timber. Now i have a couple of qbs from hlg running at 70w a piece. Pretty similar results. You can only fit so much herb in a small space.
The cobs i kept higher, the qbs closer. They can both grow good plants

Kool thanks for your help

I run 250 in my 2x2.5 tent.
5 Cree cobs running at 50 watts each.
It is adjustable, so it runs less than full most of the time, but in flower, especially during the stretch, it runs the full 250.

There's more to it than just wattage, I'd say it's too much unless the light has terrible efficiency. What light is it?
30-35 watts/ square foot is common with quality led.

True watts is input to the light, not what the light outputs. What light is it? Link?
Sounds like too much no matter what though...
