Just wanted to write to say after reading this article I went out and bought a CO2 meter. Levels in my house were high enough to effect drowsiness and trouble concentrating. (> 1100ppm, even with the window cracked) Subsequently decided to leave my sliding glass door open all day, allowing levels to drop to around 550ppm. Haven't felt this alert and active in ages. What the hell have I been doing to myself?
Earlier quoted context omitted.
It varies by plant type, health, and other factors. So it's hard to be specific. https://www.sciencefocus.com/science/how-many-plants-would-i... >back-of-an-envelope calculations suggest you’d need around 400 houseplant-sized plants.
Or you can grow spirulina or other microalgae which is much more efficient at converting CO2, and at absorbing the available sunlight. I believe you need about 5 m2 of southern facing window in a bioreactor that is 6 inches deep to convert the 1 kg of CO2 that a person creates. Can't find the citation sadly.
I have 18L of Spirulina, which appears to be having some effect, though not anywhere near a complete offset. Though, my setup is quite sub-optimal, and I've seen articles that suggest Chlorella is a couple times more efficient at biofixation than Spirulina. Continuing to tinker :)
