!!!need advice!!!!asap

i thought i had finished setting up my tent,guess again!..i have a 4x4 grow tent. inside the tent lives 1000w ushio bulb wrapped by a magnum xxxl hood cooled with a 6in vortex fan.
i also have 2 more 6in vortex fans,one to bring fresh air in and the the other to extract temp/rH from the room backed by a carbon filter..
all 3 fans have a speed controller but that dint seem to help alot...

with the hood fan at 3/4 blast,the exhaust at the same speed and the intake at about 1/4 speed yield a temp of 84.5f,wich is great for what i want..c02! that leaves me with no co2 in the tent tho,dam co2 will be getting sucked off,not by the whore down st ether.

what should i do...i ready purchased a used sentinel chhc-1 and dont want to leave it sitting there. i have two options.
bring my ballast down to 600w(new bulbs) and drop the temp down enough to keep the exhaust fan off,but the would suck because you need more light with high temps and co2..
ooooor, pick up a used 8000btu portable ac unit and run that as my cool device and the exhaust fan as an anti rH unit.

im thinking ac unit! if i go this route,will the ac always be on,or only when it needs to cool the temp. it worries me for the unit im looking at uses 934w..scary isnt it,to have it running alongside the ballast time cycle


i want to start my grow this week but find my self lost..i mos def want to run the c02 along with the ac...my question above is what worries me..the 600w is my last stand,i dont feel it be worth to run with co2...

any one?

You will need to have or hood cooled useing the fan at 100% when lights on. Sucking from outside the tent and exousting it outside as far from intake as posible. A clip on fan should be aimed tords light to push heat up to the top. Filter should be as high as you can set at 100% on a temp regular. Passive intake should be used to bring air in from outside away from any heat. A/C might need to be used to cool the rest but remember the exoust of the A/C is hot as hell so don't suck that into tent or it will run all the time. As far as useing Co2 in a tent a ppm controller will try and keep it at set ppm. But you will lose alot. A good way to fix that is use a timer set for 15 min on 15 off. PPM will be higher then 900 but not anywhere 1500 you might be looking for. Tents army full sealed so it's hard to keep at 1500 unless you waste alot. Also with the heat don't think you will have much RH problem lights on but lights off you might need your filter to ran 15 min every hour to drop the RH. Only way to tell is hook everything up and watch for 24 hrs and try different ways. Then if everything is good after 24 hrs full run bring in the plants and grow baby grow. Lol hope this helped a little. Happy growing.

kool,got it figured out...thanks g. once i pick up the ac and make a chingadera to extrernaly kool the tent...ill post pics once finished...def going to run it for 24 hrs to fine tune..
