yet another heat problem looking for a few experts

so i have spent a ton setting up my once idea of a basic grow room now im fighting a harder battle then explaining pot is good for you to your grandma

ok so the problem is i orginally ordered the 1000 watter off of the best deals thread first day relized i was screwed room hit 115 30 minutes in at that time i knew that keeping that heat down just wasnt worth the light gain so i sold locally and ordered a 400 hps cool tube set up and im still having problems keeping heat under 90 if i shut the door it can easily reach 100 f so im having to keep the door open all the time

specs:

4*2*8 closet
400 cool tube hps
electronic ballast
2 10in osculating fans

my grow set up is well hard to explain if i had to call it anything i say it is a recirculating soakaponic set up


as of now i havent added any inline fans just been using the door to exchange air im on 24 hour light cycle cause i dont want to light proof my room until heat isnt a issuse and dont want to tak the chance of light leaking on dark cycle

i am really asking what your experence with a simular set up is

should i get a protable ac or maybe spliter and ducting for the house central air

im trying to lean away from having to cut any hole as im renting in a small duplex that shares a attic with the neighbor good people pot heads but they dont need to know my business if you feel my mining any help would be great thanks

You will certainly be screwed by those temps and it is only going to get worse when flowering begins and you have to light proof the room. I don't think there is a way around some venting. Is the 400 watt light able to be air cooled?

not sure what you mean by air cooled but it is a cool tube i would just need to hook up the fans how do i do this if i decide to cut the holes do i put fan before light or after light what about intake whats the best way to accomplise this ive spent weeks on here and theres so my different set up i just wanted to know what works best

You need an inline fan probably a 4 inch like this http://www.google.com/imgres?imgurl=http://hydro-earth.com/8095-80-large/4-inch-in-line-fan-165-cfm.jpg&imgrefurl=http://hydro-earth.com/fans--blowers--filters/8095-4-inch-in-line-fan-165-cfm.html&usg=__6RjCQQWz_foDWW50h0oOvkdEEy4=&h=300&w=300&sz=15&hl=en&start=0&zoom=1&tbnid=OhdHlOsEIbC2NM:&tbnh=165&tbnw=164&ei=_eF5TfnlOJOgsQPcrvSYAw&prev=/images%3Fq%3Dinline%2Bfan%26um%3D1%26hl%3Den%26sa%3DN%26rls%3Dcom.microsoft:en-us:IE-SearchBox%26rlz%3D1I7DKUS%26biw%3D1252%26bih%3D521%26tbs%3Disch:1&um=1&itbs=1&iact=hc&vpx=1001&vpy=126&dur=4289&hovh=225&hovw=225&tx=122&ty=170&oei=_eF5TfnlOJOgsQPcrvSYAw&page=1&ndsp=12&ved=1t:429,r:5,s:0

Hook the end that intakes up to some ducting, you can get it from homedepot, same stuff they use to vent a dryer. connect it to your central air vent, just run it to the vent, the inline fan will suck the cool air and then blow it through your cool tube. With a 400 watt light you can just leave the other end of the cool tube open. My last batch was done like this, it wasnt pretty having 20 feet of 4 inch hose running through my room to the closet. I also had a fan blowing on the space between the light and the tops of the plants. Hope this helps

Yoy could dedicate a window for venting, just make a frame that seals the window with your ducting, crack the window and you have your exhaust hole
