So, I'm planning on setting up a grow room in my garage (it'll be a box about 10x7', well insulated). I'm going to be using an ebb and flow hydroponic system (homemade), the Procyon 100 LED grow light in the flowering with with CFLs to ensure full spectrum lighting, CFL in the vegetative room, and a CO2 system (tank, regulator, timer). The rooms will be light-proof, but have air-exchange between them, but not to outside the growing environment (garage), with the exception of when I walk through the doors.
I live in an area where the temperatures range from negative twenty F to positive 100 F, and my garage isn't heated or cooled, so I'll be installing a heating and air conditioning system run on a thermostat to maintain 75 degrees F. I'll have a dehumidifier in the room set around 60% RH to keep mold from being an issue. CO2 will be pumped into the system to keep my gals happy and producing.
My question is this; using this type of extreme environment control, can I avoid venting the system? I don't want to be pulling below-zero temperature air into my grow room even in short bursts. In theory, this works (so far as I can tell); the plants get a constant temperature and humidity level, and CO2 so they can complete the photosynthetic process.
If it makes any difference, I'll be growing about 56 plants total:
6 Mothers (of different strains)
12 clones
24 vegging (in two different stages: veg 1 and veg 2)
24 flowering
I'll be harvesting 12 plants every month, depending on the particular strains' flowering time.
Please let me know if you foresee any problems before I start construction. Once I have the plans all set (assuming I can use this system) I'll get building right away, and I'll be sure to share some photos with you.
