Long winded....Have built a shed for mmj. Shed is conventional built with closed cell spray foam as insulation. The floor is also insulated with foamular insulation sandwiched between subfloor layers. I started as a vented system and have switched to c02. My thought was why bring in outdoor air to heat and cool it when I could close it and enrich.But only enriching the main level flower room. The loft is still passive vented via ducting outside. Pulls from exterior and exausts this way too. (Hard to maintain decent temp ranges when outdoor air is extreme).This leads to the question. Currently c02 is in the lower level flowering room. I'm considering utilizing this as a "lung" room. (To save another bottle, and controller) Using passive ventilation (from flower room) via ac infinity fans in the upper level rooms pushing the exaust back into flower room. Think I will/would exaust the propagation room into veg room and exaust the veg room into flower.. veg would also have its own passive intake vent so it wouldn't pull through prop room.. if that makes sense... it just saves another penetration into the flower room. If that's a bad idea I can vent them both into flower independently. Is this a bad idea? (I forsee using filters in each room for bugs, I've had a bout with them already) I'll be using a dehu in flower. I have attached pictures of building as well as a drawing of what I am thinking of doing. Black is currently in place or cannot be modified. Blue is proposed walls.
I have to wait for daytime hours in flower to even enter. I don't like! But its the tallest room in the building.
Climate is controlled by mini split, main level had a 12k btu unit that gets used 100%. The loft has a 9k btu mini that is a "back up".
Even these have a 10 degree +(mainly) or - (seldom) difference from setpoint.
Lighting is or will be led.. except I am thinking of installing batwing hps back into the flower for ir. Ill be close to maxing out ac if I do.. unless I kick the 9k btu back on.
Any input is appreciated.
