    i wanted to use co2 on my new grow my grow room is in my cellar i was woundering if i could tie into the exaust vent of my oil burner so instead of all the co2 ceated by the burner going up the chimney i could vent some into the growroom and how would i go about doing this

    I'd be afraid that another by-product of your oil burner would be carbon monoxide....100ppm is considered dangerous..........if you do it, be careful.

    I made up some DIY co2 generators with champagne yeast and sugar in a milk jug and ran a quarter inch line from each jug into my tent about 2 weeks ago and id swear theres been a major increase in growth, i might be wrong but the cost was about 50cents a generator so fuck it, its worth a shot and a buck

    Yeah fuck it man, buy a bag of sugar a box of baking soda and some yeast. My buddy gave me a couple of champagne yeast packets but i guess you can use any yeast, i have a oscillating fan in the bottom of my tent and i just ran the tubing through the hole and tied to the pole in the corner of the behind the fan, i just shake the milk jugs everyday or so and i used clear tubing and you can see a small pocket of fluid in it and i shake the jug and can see the fluid move a little bit and then you can hear the gas bubbling out the tube. PM me and ill send you a pic of mine and tell you how i made it, the only tool i used was a metal tipped pen.

    I find brewing beer in my intake room serves my CO2 purposes now. I hemmed and hawed about it for a while.


    Keep in mind, those soda bottle generators are only good for incredibly small grows. You can get up to about 400 ppm in a mini fridge sized grow with a 2 liter bottle, and then only for the first few days. Meanwhile sleeping in your grow room would provide in the area of 1000ppm if it's 4x4x8 for an entire day.
