Get an amiable friend, and do some heavy breathing in the garden. Good for the plants, good for you, and if you do it right, good for your friend.
Seriously though, humans are fairly large animals, and a pair of humans does vent off a fair amount of CO2 during coitus.

Def a lot cheaper than buying a CO2 tank or one of those CO2 buckets. Have you had any experience with the CO2 bucket? I was thinking of buying one and using it on my Rubbermaid grow box. I just haven't found anything on the internet where people used CO2 enrichment with a Rubbermaid grow box.
I don't know enough about them to comment. Ambient CO2 levels run in the high 300s to start with, so at most you want to push that up another 1,000ppm or so, and mammal life is really good at pumping that up cheaply and safely under normal conditions. Grow rooms aren't usually the best enviroment for them, but fungal life also tends to generate CO2, so yeast is an option, start a culture and it will go until it either runs out of food (like sugar) or the concentration of alchohol kills it off (beer takes advantage of both properties). Or go to a Startbucks and ask for spent coffee grounds and start mushrooms in it.
There are chemicals that produce it as part of a reaction, a lot of things give it off when burnt, and then there is also bottled CO2 gas available.
:thumbsup:All about making babies..and the CO 2 would be cheaper! LOL :hippy: prQuote:

Yeah, not as much fun that way. Sometimes you just gotta do what you gotta do though, partner or not.Quote:
