Setup

i am currently growing in 2.40x1.20x2.20 tent.
I have 18 plants under 2 600W hps (dual spectrum) bulbs. I have installed one itake of fresh air fan with strenght of appx 300mh/3 and one extractor of 520mh/3.
I think that is even stronger that required. Bulbs are 50cm from seedlings.
Still i have problem with temperature, which is 32,33c-constant. And humidity that would not go above 48-49%.
Any suggestion how to increase humidity and lower temperature??
Should i install strogner extractor.
I think that the extravctor dries the air(humidity goes down, and temperature would not decrease)?
Any suggestions please?

You may want to consider a portable air conditioner in the room or wherever the tent is. Keep the outside temps where the intake is coming in and the tent will be a little cooler. Or a window unit ac. If the intake is pulling warm air, the tent will be warm. Air movement isnt air conditioning.

Yea, I agree about keeping the intake as cool as possible. Also, what do you have for circulation fans? Are the bulbs bare or in cool tubes? I would look at ways to push the bulb heat out, maybe a box fan pointed up at them or a wall/tower fan pushing towards the exhaust...

Edit: The extraction fan will pull the moisture from the tent to some degree, but relative humidity is relative to temperature, so as temp goes down rh goes up...You can always by a little medical vaporizer at the pharmacy and toss it in there...
