    Default Co2 Bags...pointless or not...?

    Surely these Co2 bags are useless in a well set up room.

    Let's take a look at this for a moment. U are supposed to sit the bags above the plants as the co2 falls downwards onto them. However the way that the air in your room circulates would prevent the co2 from doing its job as the out take fan would the co2 away before it touches the plants. Also the ocilating fan would mess things up too.
    Would a better idea not be to place the bag at the outside the room next to the intake fan? Or does it need heat to activate the bag? Oooorrrr...are they just pointless?

    Although i have no experience of these, i have read about them as like you i was pondering on the idea a while back, but like you came to the realisation that my extraction would just remove all that shit anyway... if i was you id save me money and put it towards some PK or something ;D

    Ok. Well suppose you done a proper co2 set up with canisters valves and regulators etc how much extra % more yield would there be than not using co2 at all??

    Don't think you'll notice much difference mate. Unless it's a highly professional grow set up your putting together then the gains will be minimal. Plenty more goodies to spend your coin on mate.

    Mine worked. Kept my flowering plants from stressing at 30 deg C when we had our UK short lived heatwave. Ill continue to use on my autos and let you know at the end of their cycle.

    I think that those co2 bags are pointless
    1 if your extraction and intake are really good then it will all get sucked out anyway
    2 its just a £30 bag of rotten plants
    I use co2 to help with stress from high temps cos my extraction isnt the best
    My co2 costs less than a £1 a week
    I use a few 2liter bottles half filled with warm water a bit of yeast and sugar. The yeast either feeds on the sugar or breaks the sugar down, im not sure on the exact science of it but i know it creates co2 when it does what ever it does.
    I either release the gas over the plants every day or i have drilled a hole in the lid so it releases slowly.
    Little tip dont forget to release the pressure or after a few days the pressure builds up and blows the lid off.�� spraying stale beer smelling liquid everywhere.
    Each bottle last about 2 weeks. When all the gas is gone i replace a some of the water with fresh and a little more sugar and yeast. I will do this once or twice then mix up new.

    I hope this helps anyone. I find it works for my set-up and its low budget so doesnt break the bank
    three people can keep a secret if two of them are dead

    unless it's in a sealed room with no extraction additional co2 isn't needed,

    I have a 1.5m x 1.5 meter room that is not sealed. 1 exhaust. 3 bags. Ambient co2 up from 400 to 600 average. I felt like 400 was a little low. I don't know.

    pls excuse autocorrect. i am high of course.

    Years ago someone I knew that would use co2 would turn off the exhaust for an hour or 2 as he brought ththe ppm of co2 up. Then resume normal air ventilation. He always had spectacular results but definitely seemed like a headache

    You will 100% waste your time with bags. You will also waste the Co2 if you do not drive the plant into metabolism overdrive with enhanced LIGHT, HEAT and PROPER Humidity. Make your environment optimal this way before you concern yourself with Co2. All the extra Co2 in the world means nothing without the proper vapor pressure differential to absorb excess Co2, plant stomata open the most when VPD is between 8 and 10. Check a vapor pressure differential chart on google to make sure your VPD is optimal, use a ppfd meter to check for at least 1200 ppfd light, and make sure temperatures are 78-90 degrees depending on strain. I switched to Co2 tanks, with a small room my 5 lb tank lasts forever. I use a titan regulator to control the flow, which is barely open, and a autopilot monitor with infrared Co2 sensor to automatically maintain its levels for me. I don’t use a timer because with my sealed room, it barely ever turns on to replenish the air. The key is to seal your room and use a monitor—you MUST have an accurate idea of the Co2 around your plants. My probe hangs off my light rig above the plants, where you want the Co2 to be. I use a small clip on fan, and attach the Co2 tube to the back of this fan, pointed DOWN at my plants to rain those precious gases. Two tower fans in each corner oscillate and circulate the air, which is ESSENTIAL for your plants to absorb the Co2. Following the wise instructions of growers before me, this has worked amazing so far, and remember, don’t waste time or money on Co2 if you haven’t mastered LIGHT, HEAT and HUMIDITY.

    I've seen this question asked many times on this site, and this is hands down the best and most informative answer I've come across. well done sir.

    I wasted a lot of time and money over the course of a year to finally research enough to find out exactly what you said. I hope more people read this comment, its accurate.
