Hellp Needed! Quite Bad.

Ok Here We Go..

Iv been growing for the past Month ( CheeseWreck x5 ) In a built in closet with doors using x2 30watt Fluro's to get them up and going and managed to get the Temp sittin at 28.0c and ( RH ) sittin at 50% which is all ok right UNTILL its time to change to 400watt HPs light and now Temp is at like 40.0c and ( RH ) at 0 % !!!!! HELLLPP !!!!
I have a Extractor Ducting in there at the Back Top Left of grow Room and a Vent on the Front Bottom Right for Air Inlet..
I hav 1 fan in there Oscillating 90 degrees ..
Lights on 18/6 till start to flower then to 12/12..

ANy 1 helpp on how to Raise my RH Iv tried placing a bowl of water in there to let of evaporation - nothing -
tried place wet towel over fan - Drys out to quick
Only thing im thinking of is a Cool Mist Humidifyer to let of a certain amount of water into the air an hour but that wudnt touch the heat sitution i wudnt of fort...

Can sum 1 helpppp plzzzz.... Im stressin cus i dont want this to go wrong...

exhaust is needed. preferably an air cooled hood or a cool tube for the 400 watter... once you get the temps down the humidity will probably rise again since you previously had some.

What he said....an intake from an air condioned room,added to more exhaust removing heat from the ligh area will solve the heat issue...do it quick!!!!

exhaust system..??.. iv got a extractor sucking out air from from room and a vent on front of doors wif fan on outside pushing fresh air in. is that not wat u meaning?

Air colled hood? Cool tube for 400watter?
