Indoor Grow Room Design

Hello,



I am looking for advice on this basic concept I came up for my grow room. I only have one window so will use it for intake and Outtake. I want to split the room for a veg area and flower area. I can only come up with the one intake that splits into two to keep fresh air going into both rooms. I run an intake fan from outside the tent as shown to push air through all my vent hoods on lights then above the tent and out. Is it fine to outtake fans from the grow rooms into the main duct from the vent hoods to underneath my home. I may be all wrong on my design setup just looking for advice. I also am not sure on exactly calculate what cfm my intake fan needs to be and also my outtake fan. I am not good with the program to create so I am sorry in advance it is crappy illustration. Any help would be greatly appreciated thanks again.

The idea looks solid. If you're only going to be using two fans you're going to probably need to boost your ducting to 8" instead of 6" since the rooms are so big, but other than that it looks good.

Venting is probably more complicated than it needs to be. That exhaust won't work properly. It's going to suck a disproportional amount of air from the rooms/hoods.

That being said, you could probably get away with whatever you want. Your using less lights per sqft than most, so you shouldn't run into many temp problems.

How could I simplify the ventilation and make it efficient? This will be my first room so just looking for how to do a split room and ventilate correctly.

Also you say less light what size room should I do for the lights I currently have. Thank you again

I'd stay away from squirrel fans. You have a pretty low ceiling height, and that amount of watts may be just fine for you.
If you run a couple more lights, which is possible, you run into a few issues. The temps will be harder to control, but doable. Also the air being moved would have to be quite a bit more. This can get quite loud outside your window.

Don't get hung up on plants needing "fresh air." This isn't large scale, and you have plenty of air volume, and inside a home has higher CO2 levels than outside. Take advantage of that vestibule as a lung room.

You'd probably have no issue running open reflectors. But if you really wanted to move air around, I would put a passive vent (hole in wall with furnace filter) on the veg room and flower room. No fan or ventilation in veg. Carbon filter-air cooled hoods- 6 inch centrifugal fan- exhaust out into vestibule\lung room. Dehumidifier in lung room if necessary. Cold air intake fan from window if necessary.
