Homemade co2 for small growroom


#1

wat r the homemade sugar/yeast combo like producing co2 for a small 1.9*1.9m room


#2

not sure ,but in short providing co2 is allways an improvement . many ,many,many , years ago i used to gas by using Baking Soda and vinegar and a wick [it can be cotton twine or a new small lamp wick ] but their R many ins an outs about using co2 …plants don’ts use it in the when its dark , you cant turn off home made as you say .its heavier then air , keep fans running , you need too be able to seal ur room good . when the intake or exaust turn off the must close off . in a small area home made can work well enough but depends cost verses # =$$ on a larger scale i would burn natural gas in a co2 Generator …DEFINATLY

Best way to tell if your Co2 apparatus is proving too much, or too little Co2 is to buy a Co2 ppm meter.

I forgot. You must limit your ppm level of Co2 to no more than 1500 ppm. Make sure the fans are off, unless you have your fans on a switched thermostat, whereas you will lose the Co2 in the tent, but it will build back up after temps or humidity is exhausted and replaced by fan system. Most growers like to keep the fans off, during Co2 but, if grow area is too hot or humid, then you mush exchange the air.

at what levels does it start to become effective??


#6

I believe that any C02 is proactive. Perhaps at least 400 ppm would be the minimum of usefulness. Any less and, it is probably not worth the effort.

yeah thanks for the reply but i have just small setup & dont like concept of open flame

I’ve considered experimenting with yeast/sugar for co2 production for my grow as well. I was going to do it the same way I have for my planted freshwater tanks.

Here’s my idea to combine the methods.

Drill a small hole in a 2 liter bottle cap and glue a 1 inch long piece of ridged air line tube in the hole. Fill the 2 liter with a water mixture of sugar and yeast. I think its a teaspoon of yeast and a half cup of sugar. Connect flexible airline to the 2 liter cap. Connect a valve to turn the co2 bubbles up or down. Connect a wooden airstone to the end of the flexible airline. Put the airstone in the bottom of a bucket of water (this would have been the fishtank) and once the yeast starts making bubbles, turn the bubbles down so they barely get to the surface.

This method is cheap and makes a noticeable difference on my planted tanks. I don’t know how much ppm of co2 it makes, but when I run it, I have mosquitoes constantly trying to get into my window screens and doors.

on such small environment you DONT want to deal with a co2 burner by no means . what i first mentioned was a simple way to make co2 for small area like your using but i am not sure how you would control the ppm of gas…it would be unknown unless you invest in expansive $$ equip… but adding some is easy …you need baking soda in a pail that holds more the the container of vinegar / place the vinegar over top of the pail place a wick in . Small round ,NEW lamp wicks are good …soak the wick in vinegar … a few mins. then pull a couple of inches of wick out over the edge so that it drips off into the baking soda …THE more the wick hangs out .the faster it will drip .leave plenty of wick into the vinegar container

tried that system worked fine but 2lt bottle was to small for amount i added went evrywhere haha

I used to use a cup of sugar and a pack of yeast into about three and a half quarts of water in a one gallon jug in each side of my closet with a small air line tube that went up to the ceiling to dispense it over the garden. I would add sugar when I noticed it slowed or stop bubbling, so it wasn’t really an exact science. I never noticed an appreciable difference with or without it
