I have two rooms that are both 4'x4'x6.5' in size, one being my flower and the other respectively being my vegetation room. When I was constructing my rooms I was on a limited budget, and when it came time for ventilation I may have skimped out a little bit. It's starting to gear towards spring/summer again and like clock work the temps in my rooms are going up as well.
I haven't had issues all winter long, until the girl currently sitting under my 315w cmh started having some taco leaves about a week ago. I tried moving everything around in the room including the position of the 315w, which I even raised entirely, however nothing seems to be helping with my temperature issue. At the moment, there is a large box fan running on medium angled upwards, an oscillating fan running on high, locked and pointed directly onto the cmh fixture, and a small $10 clip-on fan which is actually oscillating just inches below the bulb.
I have a thermometer hanging a couple inches above my canopy level and it's reading ~80 degrees fahrenheit, which during the winter never really went above ~72 fahrenheit at the warmest points. I remember last summer getting temperatures of 109 fahrenheit at points with my 315w and led panel in the flowering room, which I refuse to let happen to me again this summer.
When setting up and purchasing my ventilation I went with sharing fans for each room. I have one fan which I use to push air into both rooms, and another fan used to pull air out of both rooms, through my carbon filter, and released back into the air smelling clean. I used a t-connector and simply split off from each fan to each room, which has about 10 feet of ducting on each side until it hits the room. I purchased a Can-Fan ( https://www.amazon.com/gp/product/B004C2IWIE ) to extract the air out of both rooms, and only had enough money in the budget to get a cheap $37 fan to push air into the rooms ( https://www.lowes.com/pd/SUNCOURT-Inductor-6-in-Dia-Galvanized-Steel-Axial-Duct-Fan/1000018191 ).
There appears to be a somewhat negative pressure because the doors will close when they are with like half an inch to the frame. Does that provide any kind of "dead air", which would let the heat penetrate down to the plant? I keep telling myself that it's not ventilation because the only plant which is affected is the one under the cmh bulb, because the rest of the room and surrounding ladies are fine. I doubt an air conditioner would help me in that small of an area, and I already have all the fans running inside the flowering room that I can fit (reduced plant count). How can I effectively cool this area enough? I have never used any kind of a fan inside of my veg room and there has never been any issues with wet leaves or stale air on that side, however I am only running a 4 foot t5 fixture there as well so that might have something to do with it.
