C02 is heavier than air and essential to plant growth. I’ve considered cutting two holes from the floor in my garden room through to the cellar below, serving two purposes; the first being a heat vent and second as an uptake for fresh air and hopefully higher concentrations of C02 than could be supplied by a first-story window.
The cellar has several open vents and an open doorway but smells of stagnant water and mildew. I live in a heavily forested area with lush greenery that grows up to 15ft. from my home.
Is it possible that higher or lower than average concentrations of C02 might exist in my cellar at an extreme that merits special consideration?
Thank you, Aeroponica
If you want to increase the concentration of CO[sub]2[/sub] in a space, couldn’t you just light a candle? (A scented one might help with the odour too).
It’s also worth noting that plants need oxygen too; not that you’re likely to build up an environment that excludes it completely. Plants respire just like we do; it just happens that when they are exposed to light, photosynthesis (a completely separate process to respiration) results in a surplus of oxygen.
It doesn’t separate from air easily, but the reactions that produce CO[sub]2[/sub] make it a high concentration, and already separated from the bulk of the atmosphere. This form of CO[sub]2[/sub] pools quite readily. It’s one of the main reasons mines and tunnels need to be ventilated. If the air is still, CO[sub]2[/sub] will also pool in low spots and in basements.

High maintainence. I am trying to minimize my daily must-doos

Not a bad idea. They actually give it away at my local Co-Op. Any idea how long a brick lasts?
Squink, thank you for all the great links.
I am looking into renting a CO2 tester. Who knows for sure unless I test, right? Then I can experiment with all the different C02 supplement methods as well. I’ll post the results. Thanks again, Aeroponica
