Ok last problem I'm battling with is heat. I purchased a inline fan from Lowes but that's to moving enough air to keep the heat down. My tent gets up to 90 at times. Any recommendations as to a strong quiet fan.

I recommend in your case in your space a 4 or 6 inch inline fan the type used with hydroponics and a speed control for it.
Buy local or check prices online , compare the two and buy from one of them.

the trick is to bring cool air in and blow warm air out. Two fans

maybe a 2nd same fan ?

Is there any other way of raising the RH other that a humidifier?
Hey...I grow in an extremely dry environment and get decent plants, despite the 18-22% humidity with temps hovering at 82-85F . You can buy a Vicks vaporub air mister to help increase the humidity(havent bought one to try yet)

How are you extracting the hot air out of your space? Do you have negative pressure when the tent is closed?

With the addition of a third light I had to upgrade the fan setup as the 3 lights was a bit too warm for the space(space is 54" long, X34 high X20deep and the lights are X2 Galaxyhydro 140wdraw and X1 Mars 180wdraw). I bought a 6" axial fan and it keeps it nice at 80-83. Not growing in a tent, but in a custom stealth cabinet. Complete pics of setup in the link in my signature

Nice man I'm going to check your grow out . I'm about to get 2 of the 300 watt units for my 36x20x63 tent and hope to see low 80 temps.

With that amount of height keeping it at 80 should be an easy task, especially with 2 lights.

As long as I'm under 85 I think I'll be alright. Probably use silica any ways.
