*DIY CO2 Generator*

I recently wondered if there was a cheaper alternative to giving my plants some CO2 and stumbled upon the Yeast, Sugar, and Water method that slowly produces CO2 from the sugar, i was planning on having a 2x4 or 3x3 box and using 2 or 3 2 liters for this experiment, I know its heavier than air so put it above the plants maybe behind the fan, but ill keep my tent closed most of the time, but will also have an exhaust fan and carbon filter running.

SO MY QUESTION IS
Will doing this be a waste of my time for my plants? or will adding some CO2 be better than adding none?

Any help would really be great, especially from anyone who has used this method!

:peace:

I think it really depends if you are able to contain the CO2 enough to raise the levels to a proper PPM. Then having very high intensity lights to follow up with that inorder for the plants to take up the excess CO2.

If you're going to supplement CO2 then you'll want to be sure your growing space is well sealed and that you are not ventilating air to manage temperature.

Other fermenting options include brewing beer. That way, you get something worth having out of the fermentation process!

I recall one hapless grower complaining about their nutrient troubles. They were growing their plants in a bed of sphagnum moss in an ebb n flood table. Their sealed room was humid and they couldn't figure out why the CO2 levels were as high as 2500ppm. The poor soul was decomposing his growing medium in the table and the plants were suffering!

Along those same lines, there was an organic grower here last fall who was working on an organic soil mix that would decompose and release nutrients to the plants- while also releasing CO2. He took a lot of heat from other members but I still think he was onto something.

In all cases you will want to monitor your CO2 levels so you know what you have- or don't, as the case may be. Ambient CO2 levels nowadays is a shade over 400ppm (nearly 100ppm higher than when I was born, a deeply sobering thought of one considers the larger implications).

If your CO2 levels are well above 400ppm then your supplementation regime is probably working. Be sure to take the reading as soon as you enter the space, so your own exhalations don't skew your readings.

Thought I'd ramble in here a bit in the hope it helps. Best of luck and keep us posted on your progress!

what if i had a carbon filter on low power at the top of my tent and had the CO2 coming out lower, its heavier than air so itll sink toward the plants wont it? I suppose some would still get sucked up by the filter but surly the plants must absorb some of that CO2 shouldn't it?

As long as the co2 is cool it should work.
