I am planning my grow room as seen in the picture (it's 2.5 x 5 meters in total). The air intake and exhaust CANNOT be moved or exchanged, these are the only places they can be.
Blue is for air intake (venting on ground level), the air stream supplies both rooms. Red is the exhaust fan near the ceiling.
I am having problems deciding how to move hot air from the veg room to the exhaust properly. My initial thought was to have a (light-shielded) small fan (shown in purple) near the ceiling between the veg and flower rooms, moving hot air from veg into flower, where a strong squirrel cage ventilator will draw it to the exhaust.
Do you think this setup is viable? I know I'm basically moving "spent" and warm air from veg to flower, but since it'll stay near the ceiling, that shouldn't create too much of a problem. I could of course string a flexible tube from the small inter-room fan to exhaust next to the squirrel cage... or shouldn't I? Any input is very much appreciated!
