exhausting and i still have 88 temps

the ongoing battle of temp sigh. 88 sure is alot better than 96 lol but i still should be seeing better i'd think. 4x2 closet grow. i didn't feel like tearing up my door so i bought dry wall and did my own thing (should c wat i did in my pics). 600w light turned down to 450 (not the slightest clue how accurate the ballast is). but i'm not to sure if i have enough negative pressure with the cracks around my door to pull air thru my 4x7" passive intake at the very bottom of my door. i'm working with a standard 6" duct fan.

yes i know its not smart to exhaust and intake from the same room but i don't rly have a choice and i keep my bedroom door open to help cool it. its a good 72 in my room so i don't know why it'd be 88 in my closet. shes getting little hairs/buds evvvverrywhere so i'm trying to nip this in the butt asap. the crack along the door isn't nearly as big as it seems...

don't know y my phone can't take a good picture..atleast have it facing the right way up. makes me want to throw it across the room but u get the idea of wat i'm working with.

o cool u can click on the pic and it gets bigger.

Turn your phone sideways, like you would hold a camera. (or you can rotate them in windows picture and fax viewer)

Typical rule of thumb is to intake cooler air via outside/cold room and then exhaust into a separate room so you're not just sucking that warm air back into your grow space. If your temps are still too high, then you have another issue such as too low CFM's or you have airflow reduction from your carbon filter.

You need to exhaust into the attic,another room,our out the window via a window exhaust box.

If you're dumping your exhuast into the same room the closet pulls it's fresh air from then you're heating up that room,thus further jeating the closet.

i could make a whole in the left side of my closet and exhaust or intake air from my living room closet but i wasn't trying to tear things up to much, so far i have gotten away with drilling at most 4 holes and thats in the side of my door. maybe i could reposition my exhaust fan to get a better pull off of it? cuz my original thinking process was i could exhaust up top and pull the cooler air from the bottom and its literally 70 degrees in my bedroom so i don't know why my original plan wouldn't be working.

Try lowering the exhaust fan right next to the light and see if that helps at all.

thats wat i was thinking..have a cool tube effect except without the cool tube : / just pointed another fan up at the light so i'ma c wat that does first. and i'll let u know what my temp drops when i move my exhaust. thanks for the input guys

All good BUT shooting hot moist air into a cool attic causes condensation and thus black mold. Lets skip that and go with a roof vent if going up through the attic is the only option.

This is true,but only in areas where the outside temperature is truly cold,like it snows.

Here,in the Southeast we don't have to worry about that.

Spend $30 on a surface temperature gauge. You'll find the air temp is always higher than the surface temp of the leaf. I recommend about 77 to 79 on surface temp and 80 to 82 air temp. Provided your staying within 45 to 50% humidity and have good air exchange. I'm sorry I didn't read every post, is your light cooled outside room air and what type of exhaust fan air you running for your passive air exchange?
