Indoor A.I. Growroom Build (Aquarium Interface)

[Spanglish]

Need an HVAC engineer to calculate that. There has to be a link in GrowWeedEasy.com on this.

To calculate multiply length x width x height of growing area e.g. A room that is 8' x 8' x 8' will have a volume of 512 cubic feet. Your extraction fan should be able to adequately exchange the air in an indoor garden once every three minutes. Therefore, 512 cubic feet / 3 minutes = 171 CFM.

Hope is of some help to you guys in creating this ganja heaven, where environment is key to everything !!!!!

P.S @Betelnut love the pics and look of the setup so far, those lights are a OCD dream and ohhhh so pretty and clean.

According to the link above I should be ok (if my quick calculations are actually correct anyway). But just barely. So instead of the 100mm (about 4 inch) in-line fan I might bump up to 125mm (5in) one just to be safe.
The intake seems to be fine and shouldn't cause negative pressure in the room.

Only on AFN can you get accurate info....w/o any BS.

Go and Grow.

You need to have some negative pressure to circulate the air. When the exhaust comes on there should be enough negative pressure to suck in the cooler air from the bottom of the grow area.

Always helps to be accurate when handling any kind of shit

Here you go @Mossy you want a new exploding poop emoji, who says getting stoned in unproductive lol

Yeah, with the kitchen exhaust fan blowing into the room it should allow the in-line fan to work at maximum efficiency. But the smaller carbon filter would bring that down again, so I'm thinking I'll get the 125mm in-line with the 300mm filter.

Here is the rating on the 150mm in-line I have now. I would use it, but it is way too loud:

I did some more refined calculations.
My room is about 109.5 cubic feet, so 36.5 CFM would be enough acording to that site.
The 100mm in-line says it can do 176.5 CFM, so even though it will be way less than that real-wold, it should still be ok.

Of course:

So I will have to see it all working before I'm satisfied.

As long as the air is exchanged. Fresh air is really important. Mimic the outside inside.

I am a little worried about the room the closet is contained in having enough outside air venting in.
I can put in a window vent, but it might actually be too cold for that in a month or so. Worse case I do have an ac/heater in the room, or I can use an LP-heater for extra co2/heat. But I would much rather just build it so it wont be an issue in the beginning.
