How can you supply CO2 to speed up the photosynthesis process?


medical supply
Jonathan D asked:


I’m growning medical marijuana for anxiety. It’s said that people supply extra CO2 around the area of where they’re growing it to get it to grow faster. Problem is, I don’t know how to supply more CO2, and I’d rather not stand over the plant and exhale all night and day. Lol. So, how can I do this? Thanks.

    Well, theoretically, you’d supply it the same way you’d supply supplemental oxygen to a person. With a tank of gas.

    So, I guess, you’d start by growing the thing in a confined space, like a closet, which means you’d then have to supply it with artificial light. Then, get your hands on a tank of C02, and you can regulate how much extra C02 is released into the space where it’s growing. Sort of like an incubator provides supplemental oxygen to a baby.

    But honestly, that seems like a heck of a lot of fuss, not to mention expense, for what would amount to a small increase in quality.

    You can do much much better at increasing the desired characteristics of your plant simply by choosing your stock wisely. A clone of good quality will outperform, even in poor conditions, a plant with poor stock, even with all the amenities in the world.

    One way to increase carbon dioxide in an area is to make a mixture of sugar water and add yeast, in a bucket or some other container - Plain old baking(dough) yeast.

    As the yeast multiply they release carbon dioxide. As long as the yeast has a food source (sugar) they will continue to perform.
    If the yeast should die for lack of food you can start a fresh batch.

    Easy.

    If you’re growing with ventilation, fans & scrubbers, most of the CO2 you add will be sucked out before it has an effect on the plants unless you put your vent system on a timer, your CO2 on a timer, and have only one running at a time. If ventilation’s not an issue, try the yeast method. Cheap and simple…
