Cut hole in central air duct and run a duct in there or make an intake? I dont see how it could still be hot if youre exhausting outside?

I have 2 sucking air out and 2 fans pushing air around in both rooms and still gets up to 90

Yeah totally, legitimate questions that haven't been asked and answered a hundred times. The subforum for grow design has all this information. Same with the search bar. Not being a hater just saying you can look a bit harder before asking these types of questions.

I typed in the search to hot and could not find to much

DrMcSkunkins · Apr 24, 2017

Are the scrubbers hanging over the lights or on the floor?

Make sure you are exhausting the hot air off the top of the room so the cool air can natural flow in underneath the hot air! Are all the fans working together? For instance if you had four fans on four wall all faced toward center.... having all the fans blow to the left would give better cooling than all four fans blowing toward center... IE:swirling the air allows better heat dissipation IMO.

I have them pointed where they move the air around room

What I would do.
Try and make the last 2 hoods air cooled. If not an option. Mount 1 fan and have it blow the hot pocket of air from between the tops and glass. Can do this on all hoods.
If you don't have any cool air coming in, all your doing with fans is moving hot air around. Nothing more. You must bring in cold air, and exhaust hot air for any temp changes to happen. Any chance of tossing in a window shaker ac or portable? You can "make" a cooler, a lot of ice, and a fan to drop the room a few *. But ino, waste of time, money, and equipment to hope to lower temps a few *.

Cut a hole in wall a foot above floor. Run a fan and duct work from ac room I to hot room. Cut another hole up high in wall across from entry hole opposite side of wall. Run fan and ducting as well. Put both fans on speed controller. Allow for slightly neg pressure. This may help cycle in cold air and remove the hotter air. May take 30 mins to start working.

Also, why 2 scrubbers? One is not needed on ac hoods. Use saran wrap around all ac hood ducting and tape securely. Also, caulk your goods and seal them right. I do this for my sealed ac hood flower room

I have one on each bc it stinks big time in both room u walk any where near that part of my house out side u can smell it

tinderthumbs · Apr 24, 2017

shots of one room old pic now I have a real fan hooked up to that light

DemonTrich · Apr 24, 2017

See pic 1
The reason it stinks is your pulling room air thru your ac hood then out. This is how I run my ac hoods. Duct/fan/wall/duct/hood/duct/hood/duct/hood/duct/hood/duct/wall/duct/fan/duct. I pull hood air thru my lung room, then dump on the other side of lung room. All ducting, elbows, are 3x wrapped with saran wrap and hvac tape. All hoods are fully sealed, and I always put weather stripping on the glass, so it's make a great seal.

If your scrubber can't keep up, you need a bigger scrubber and fan setup.

Always remember, hot air rises, cold air sinks. You want all you incoming air coming from below, and all exhaust air blowing from the top.

2nd pic, your blowing how air down low. Everything on that wall will be hot/warm air negating and cold air that was there.

DrMcSkunkins · Apr 24, 2017

I like my fans pulling the hot air out, outside of the room/tent. If your new fan is on the same side of that light as your fan in the pic then I think it would work better on the other side. When you push air through the hoods they leak out hot air from every crack.

Freshone · Apr 24, 2017

Is that a regular fan with the base ripped off blowing into your hood?Are you not using inline fans?If it is that shits blowing 90% of the hot air right back in your room,lol.

Sounds like you need to cut an intake hole in the wall preferrably to a dark room. If no dark room you could build a bat box with a hole cut in it and attach to wall.
Kinda like the model one pic but with a hole in the front and back, the boards would block light from entering.

If youre already exhausting outside and the room is sealed it sounds like theres no air exchange.

good stuff

you are every right there is almost 0 air exchange that is why im just pushing hot air around I would of thought the air being sucked out of the room would of let the room cool down with all the fans

and that is what is my problem I don't want any light leak or way for bugs ect in to my room

I thought air cooled would of been ok and more power then led boy was I wrong

DrMcSkunkins · Apr 25, 2017

If you build a light proof box put a giant green scrubbie that you find in the painters aisle over the holes to help keep out bugs.

tinderthumbs · Apr 25, 2017

how do u build a light prof box lol

so thinking I might cut hole in bottom of wall run duct in to it then put a fan pushing air in to it from my cold room and just have to close the hole when night time

You can't cool a hood with hot air first, and you need fresh air added in there somewhere.
I had to plumb cold air into my space , by attaching a vent line to my AC .
What size is your spaces?

It's still ghetto for now but it's doing the trick.
