Live Stoner Chat Negative pressure

[Micky&MalloryKnox]

Just me again,

I currently have a 4""inlet booster fan bringing fresh air into my space. However recently temps have been increasing and I'm not sure whether it's due to the outlet fan no longer pulling enough heat from the space or the inlet fan no longer pulling enough cool air into the space.
Should I be letting the negative pressure pull air into the space or should I be using a fan to pull it in. ?

Space is 210cm wide by 170cm high 60cm deep.
Now this space is the bottom area of the cupboard with a split shelf so there is a further 60cm by 60cm by 220cm of airspace above the shelf. (All power equipment is on there) fans and filters are fitted in the "actual grow space" below the shelf. There is a space of about 20cm between the wall and the shelf allowing air to move between the lower area (grow area) and upper area (empty space).

I calculated my fan size with the space below the shelf. Should I include the empty space above.?

Finally thank you for reading this far .

After 're calculating it's become clear I'm stupid....

I'm not moving enough air require a larger outlet fan.

Just some advice of your pulling and venting into the same space your not going to effectively cool your tent because you will be in taking room temp air and exhausting hot air in turn increasing the room temp air you pulling into the tent. (I know it’s a given but you would be surprised how common of a mistake it is especially when it comes to stealth.)

Like a dryer, you need to vent the heat to the outside, unless you need heat in that and adjacent rooms. Right now, I'm venting my warm filtered tent exhaust into my room, and haven't had to otherwise heat that room even now, when its below freezing outside.
