Can't raise moisture in room and the temp is too high (using HPS). What to do?

Thank you for elaborating a bit more. It’s helpful to see this bit:

The outside temperature of the intake air is 46F.

I was wrongly assuming your ambient intake air temperature was consistently much warmer than that, and the heat was in large part due to insufficient cooling capabilities.

If possible, before plants ever go into a space it’s a good idea to run the space 24/7 with the lamps on for a while and also leave it with the lamps off for a while and record the temperatures and humidities across the day at different times. This can help dial in the most ideal timed light cycles to use if your schedule allows such customization.

Also, I didn’t put the fan to blow on the lamp, because I saw somewhere about the wind burn when the fan blows directly at the plants.

It’s advisable to have good airflow within a space with fans and such but yes you’re correct in that you don’t want the fans blowing directly onto plants very much at all. It’s good to have it blowing nearby or bouncing off a nearby wall first. I think it’s good to see the leaves on the plants gently dancing, so to speak. Soft subtle movements throughout and across the plants foliage.

For it to get 85F during lights on I’m guessing that the intake air is much warmer during the day and after the sun goes down the temps drops quickly and stay pretty low. Highland types would seem to do best in these conditions, or better performing hybrids based on redeemable qualities from highland types, so if you didn’t want to change your atmosphere you could change the genetics potential going into your space. Cannabis has shown its adaptive qualities from the equator to 40+ latitude. But also a large draw to gardening indoors is so that you can customize the atmosphere and grow something unique that you otherwise couldn’t. There is so much personal preference with indoor gardening, similarly everyone’s set of resources and resourcefulness vary. It makes each garden so unique and full of character.

A lot of helpful comments in here I’m learning a lot from this post thanks for starting this conversation @M_Jake. That’s such a beautiful garden @Chuckeye, the plants look wonderful! Hope everyone is having a great day. Many blessings and much love
