Well as I suspected its low humidity (30) bought a dial today and as you say high temps aswell 85f
Its got me puzzled tho,my new rooms 6x6x7 intakes 6" and extractions a 5 and 6 inch fan i thought 11" extraction would handle it without any problems,how wrong was I...i had to pot up today to 6.5 ltr pots and in doing so i added a 600hps to the 400hps i was using so 1000wts in total now and still hot,I know its been around 80degrees outside today and im drawing that in thro an open window,just cant understand why my extraction aint taking as much heat out as i expected?
As for the humidity ive stuck 2 10lte buckets of water in the room,but i cant see any difference on the dial,any advice is welcome and thx for your time again in replying,its very much appreciated.

Your humidity will rise into the 50-60% area as they grow bigger because the plants are perspring alot more, for now it is fine. Where exactly are you taking your temperature reading? HPS are relentless, I can see your intake in the picture so your exaust must be at the top of the room somewhere. Remember that you need to get a reading directly above the canopy of the plants. Raise the lights or ditch the 400w for now. At that stage its better they get an optimum environment.
