check my set up

so hey i just set up my grow room. i have all the equipment worked out that not what i have questions about. i have a 400w light. just catch me it iam wrong. my room temp is 90 F or over but i got a 100 cfm exhaust fan. is that good for a 400 cu. feet room? and will that cool it down? if it dosent i will buy a swamp cooler. but the room temp. should be bet ween 70-80 F right? i have me seeds germanating, in the humidity dome it is about 84 F. i am keeping the rockwool wet but not soked. i conditioned the rockwool and they are now in a 1/8 - 1/4 strength solution. reservoir temp is room temp. startingseeds under floro. ph 6.0 - 6.5 . aa yes i also have a cirulation fan. so my question is, is all this correct. is there any thing i should change to optimize my room to grow marijuana. thanks to those who help. PEACE OUT

Go get em... your off to the races.. you sound motivated and knowledgeable...

some people have success at 90f and others fail miserably....
It should not be humid.... at 90 degrees, any humidity will bring problems with it... bring in lots of fresh air from outside, you want as much CO2 as possible at 90degrees... if you are in a humid enviroment (east coast USA) you may be in for a hell of a ride during the summer months

1. Keep the air in the room moving
2. PH and ppm regularly
3. Watch your leaves closely
4. Donâ??t show people you PLANTS lol
5. Donâ??t show people your plants
6. Donâ??t show people your plants

Except us on the board.. post some pics.. : )

I've just experienced same heat probs and I was running 270cfm exhaust with 80cfm at the intake for a 640cfm room. It was not enough, but I was running 3 600w lights. Solution was more construction to set up an in-line airflow through the lights. If this is not an option, I would upgrade my exhaust and place the 100cfm at the intake. If this is not enough just run the intake fan constantly, while the exhaust run intermittently as necessary. And as mentioned earlier, Co2 helps. Play it safe and make changes before plants are in.

i live in new mexico so humidity is not a problome. i want to try to get my temp lower i want my plants to be as happy as possible. and the only people that know about my plant are fellow growers and we all got each others back. thanks for the input. if i can get a camera i will post pictures.PEACE OUT

my room would be 90 under my 1000 watt, but i just have a big fan on them 24/7...brings temp down to 84 or so and they grow great.. just keep air movementy through the canopy..

dont show ANYONE! hate to say it but you cant trust your buddies either..unless you can personaly beat each of them up..

no me and my two buddy growers we all got each others back i have known boath of them for like 11 years. i am not worried about that at all.
