Question on CO2..
I have a 10*14 foot cellar with 2 meters of headroom. In there, I currently have a mum/clone cupboard, a 120*120*196 (had to shorten the poles) budbox with 4 individual scrogs, and a 1 meter square area sectioned off for vegging.
I'm getting another tent (same size) and am building a little mum/clone/early veg area in the sectioned off bit. Looking to have a perpetual grow on for a while. 12ish plants (4 vegging, 4 early flower, 4 late flower), with a 50 cm scrog canopy.
The tents and veg cab have/will have ample air exchange (quality RVK), but the cellar itself doesn't have any fresh carbon dioxide aside from what I breath out and whatever creeps down the stairs while I'm down there..
A. Not worry.
B. Sort out cycling the air in the cellar with:
I. House air
II. Outside air
C. Create CO2 with:
III. Some other method
I'm going to read up on symptoms of low CO2, but I'd appreciate firsthand info, if you have it..
All knowledge gratefully received
