Greetings all uh yall
Here is the deal. I share a minisplit between my veg and bloom rooms. Split is in bloom, I have a passive intake that consists of 2x8" holes low in the corner of bloom passively allowing air into veg and an active, 8" 747 CFM exhaust fan that pulls air out of veg back into bloom. Currently there is a 9 degree drop between bloom 69 and veg 78. I just added the second hole, before this I had an active intake and matching exhaust but this was creating positive pressure in my veg and co2 was escaping the space not to be recirculated.
Now with the passive intake, I have neg pressure but the veg isn't being cooled properly. I thought that with the addition of the hole, I would be able to pull more air through the veg, after cutting the first hole and not seeing results, I opened the door thereby creating a huge passive intake and only was able to cool the room to within 5 degrees. Bloom 70 veg 75. This is obviously better than nothing but I can't run the room like that while flowering and still confused as to why the temps dont match closer. Theoretically speaking, I should be able to pull more air through veg with a bigger intake and cool room to lower temp. Intakes dont get bigger than a door so WTF?
Here are some pics to help you envision my disaster.
Any help is greatly appreciated, I originally posted this in the thread in my sig but haven't gotten much help. Any input is greatly appreciated.
And some root porn for all you pervs.
