My "Eldorado" Grow Room

So I went and bought an expensive climate control unit and can’t even use it. 1st problem is heat. I’m using 400w cool tubes that are properly vented but the room without the ac unit running will exceed 85 to 90. Probably because im having to use 2 humidifiers to maintain 60 to 65% humidity thus bringing up the temperature. I hear everyone talking about a dehumidifier but I can’t keep up the %. What am I doing wrong? The ac unit is outside the room so that’s not pulling it. My exhaust fan is an active carbon filter attached to a 44ocfm fan and my intake is a 440cfm as well pulling from cool but "dry" basement air venting outside. So that’s all I can determine that’s holding down my humidity. So the second problem which is linked is that the room is suppose to be completely sealed but as soon as I seal it, it wants to explode due to the air pressure. I have 2 speedsters controlling the 2 blower fans but can’t seem to equalize the room!!!! My babies are young and are starting to smell already! This could pose a problem. SO PLEASE CRETIC! ANY HELP OR OPINON IS APPRECIATED im tired of throwing money at the problem

well if your flowering then you want lower humity also high humity makes the carbon scrubber not work so good make sure ur ballasts are outside but looks like they are also how well insulated is the room they are in ? how hot is it outside ?
also for the pressure thing keep the intake on lowest setting an exhaust on the highest setting, remember the carbon scrubber removes alot of the pressure so you prob have alot more imput pressure then exhaust , third looks like your running mh so im guessing ur vegging which explains the humity mh is alot hotter than hps so i would try not using the humidifers and see how that works i know prob didnt awnser too many questions but more details are needed also make sure exhast output is far enough away from room for ambient hear

Thanks dhhbomb for the reply/ input. I am flowering right now with 400w mh 16hrs/8hrs. with 4 strands white widow, northern lights, bubalicious, and master kush. My ballast are outside the room and the room is completely sealed from the outside elements. my exhaust is blowing outside and im pulling cool but dry basement air. I’ve adjusted the fans speeds, to exhaust high, intake low. It only helps a little tho im changing the air in the room every 15 min. im still having to blow cold air from a stand alone ac unit from outside the room, thus increasing the air pressure in the room. If I don’t run the ac the temp will go up to 90, im using vented cool tubes. I was trying to cool the room with the intake like the book says but im learning that every room is different.

The other thing im stressing about is my lights. Im only using 2 400w for 39 plants. When I germinated I was expecting only to get maybe 24 of the 40 I ordered and all but one grew! I have duel ballast and I will be using the best hps bulbs I can get my hands on. As you can see in the pics I mylared all the room to get the best refraction. I’ve spent 5 fucking k so far the wife will kill me if I spend a cent more! Do you guys think these plants can produce 2 ounces each with the current light configuration? The plants have room to grow at least 5 1/2 feet. oh and I will be using co2 during flowering.

ok a couple of question why not run 12 hours on and 12 hours off thats what is th norml second if you are in the flower you dont need to add any moistore to your room and i would wither keep the exhaust on 24/7 or almost stop using it when the air is on since that exhaust hot air out of the room
dont worry about not having enough light idk how big your room is but your just running a sea of green set up more smaller plants = bigger total yeild also uf your using co2 u can have temps in the 90s easily i wouldnt expect 2 oz a plant espically since this appears to be your first grow 1oz a plant is a good attempt

Ok for a second there i was thinking no way 2oz off flowering from that small.
2 600's would be optimal for that size but like u said u had unexpected germ rates.If they arent feminized u could still be working with less later on.
Sounds like u have everything u need,just gotta get it dialed in and balanced perfect. Best of luck
