One of the major differences is led radiates very little heat on to the plants, so your leaf temp is the same as the atmospheric temps, with hps your leaf temp is about 5 degrees higher than atmospheric.
Just did my first led crop. Was worried about foxtails and airy buds but they were killer. 160w buds look like 400w hps bud. Temps at 81 like renfro said
Awesome guys that’s really helpful .
warmer weather is just around the corner so I will do as suggested and turn the temp setting for the fan side of things up a touch and reset min/max temp setting speeds . Hopefully get there in the end. You guys have all been really helpful and I thank you so much.

Cool more power humidity and heat it is then.
no wonder I was doing so well in a small wardrobe years ago with a 400w m/h +sodium
Years ago them days didn’t even check temp or humidity just stuck a light up in a white painted wardrobe and an extractor fan must have been real warm and humid.
That's what it is. If the heat is married with humidity, you'll get explosive growth. The three things work in tandem, heat, humidity, and light intensity. Keep that in mind and you'll be able to solve your problems a bit easier.
