    And Im amazed that people think fungi dosen't = Rotting compost.

    Actually yea smart guy, it does mean that fungi is creating rotting compost, what do you think is happening to the stuff that fungi is eating? Its breaking down into compost.

    And didn't I say that ROTTING COMPOST does produce co2 in my post? Yes I did.

    You should reread my post and educate yourself.

    + rep for catching that i was thinging that same thing
    this guy just dont like the way "rotting compost" sounds
    but thats what it is - he can give it a fancy name if he wants
    no mater if it straw, rice, or coffee all that shit is composting (rotting)

    This title caught my attention, and then the rest of the thread was filled with equal parts of my jaw dropping, eyes rolling, and at times some hysterical laughter.

    For anyone who wants to introduce fungus, nasty odors, and a host of possible issues from decaying organic matter into your grow room - God bless ya.

    For those who actually contemplated this before saying to themselves "what the fuck am I thinking", I would suggest spending an extra $100 or $200 and getting yourself a nice regulator and CO2 tank off of Craigslist.

    I couldn't think of a more counterproductive waste of money then a bag of CO2 that you can't control, and which (in theory) would produce WAY too much CO2 when first opened, the correct CO2 for a couple of days to a week (tops), and then not nearly enough CO2 for the remainder.

    As an aside, for CO2 to "really" work, you need a ~fully sealed environment, and anyone who's taken the time and expense to do that (99.99% of them, anyways) have a more economical and reliable method for CO2.

    I honestly think all the DIY CO2 methods are really just spam from the sugar and yeast industry salesmen, because they don't do a lick of good.*

    yep sugar n yeast.

    yeah , im not to trusting of the sugar yeat method
    i dont think it does anything- has anyone tested this with a meter in a sealed room
    i know it makes bubbles in a fish tank (for underwater plants), but is this enuff for a sealed grow room a fish tank is only so big, maybe if your seald grow room was a 30gal tote , but even then how fast would the plants use the co2
    the best co2 methods hands down is tanked or BURNING HYDROCARBON FUELS (like the hotwater heater co2. or portable stove)

    Generators work pretty well, too :bigjoint:

    how much was the gen
    and please explain that first shot is that like a co2 meter and a on/off timer
    and does all that come with it
    Bob Smith

    Bob Smith Well-Known Member

    The generator was $315.
    That first shot is my Sentinel CHHC-1 - it's an environmental controller (controls my dehumidifier, heater, fans, and CO2).
    And no, everything is bought separately - the Sentinel is ~$520.
    I also have a regulator and 3 20# CO2 tanks that I use.

    right now this is what i plan on going with
    this is the best diy concept i have came across on here so far
    the co2 is constent and free

    Yeah, I saw Tat2ues's (sp.) thread as well - that's just a little iffy for me.

    Hate to be responsible for killing everyone in my house because I wanted to add some CO2 to my grow and didn't feel like shelling out some cash for it.

    If you're comfy with it then more power to ya, but there are some things I just won't touch - electricity and natural gas are towards the top of the list.

    i here you but the science is the same
    if it makes a blue flame it burns off co2 as a by-product
    in this video this guy take the face off of a co2 gen that is sold in the stores (the one on the right) its just a bunson burnner in a metel box (start watching at 02:05min) that same blue flame is made buy stoves, water heater ,forced air furnishes


    This has been the most common method of CO2 enrichment for many years. A number of commercial growers and greenhouses use it in their larger structures. The most common fuels are propane, butane, alcohol and natural gas. Any of these fuels that burn with a blue, white or colorless flame will produce carbon dioxide, which is beneficial. If a red, orange or yellow flame is present, carbon monoxide is being generated due to incomplete combustion. Carbon monoxide is deadly to both plants and people in any but the smallest quantities. Fuels containing sulfur or sulfur compounds should not be used, as they produce by-products which are harmful.
    Most commercial CO2 generators that burn these fuels are too large for small greenhouse or indoor grow room applications. Some small ones are avai fable or a Coleman lantern, bunsen burner or small gas stove can be used. All of these CO2 generators produce heat as a by-product of CO2 generation, which is rarely needed in a controlled environment grow room but may prove beneficial in winter growing and cool area greenhouses.
    The rate of CO2 production is controlled by the rate at which fuel is being burned. In a gas burning CO2 generator using propane, butane or natural gas, one pound of fuel produces approximately 3 pounds of carbon dioxide gas and about 1.5 pounds of water vapor. Approximately 22,000 BTUs of heat is also added. These figures can vary if other fuels are used.
    To relate this to our standard example in an 8' X 8' X 8' growing area, if you used ethyl or methyl alcohol in a gas lamp or burner at the rate of 1.3 oz. per day, we would enhance the atmospheric concentration of CO2 to 1300 PPM if the room was completely sealed.
    An enrichment standard of 1300 PPM was chosen as it is assumed that 1500 PPM is ideal, and that the plants will deplete the available CO2 supply by 100 PPM per hour. Remember, the normal atmosphere contains 300 PPM of CO2. A 100% air exchange (leakage) every two hours is assumed to be the average air exchange rate in most grow rooms and tight greenhouses. If many cracks and leaks are present, this exchange rate will increase significantly, but added CO2 (above 300 PPM) will also be lost. If a vent fan is in use, disregard CO2 enrichment, as it will be blown out as fast as it is generated.

    I see your post is some years old do they still sell the co2 bags and if so did the price go up thanks new grower tring to get my room rite.

    This thread is 7 years old...

    And what's stopping you from contacting the company considering all the info you need is in the OP?

    More importantly. Do you think this thread would have only lasted a month if these really worked?
