c02 Questions Someone please help.

Can someone please explain to me the basics of c02? How often does it need to be on, in what intervals, what period should i stop the c02 at? I have heard all the way through then i have heard stop after 3 weeks of flower. Also lights on or lights off i keep getting mixed information can someone please explain to me the basics of c02ing!!

I cant answer all your questions, but.

If you search through a page or two of co2 questions, there is a calculator that tells you how much you are gonna need to use based on the sq footage of your room.
As far as I know, plants can't use co2 during darkness and it's no benefit at all and a waste of money to keep using it at night.

Here is the link:

ok i think i got you covered bro.........so ive been using CO2 and iam in flowering on my O.G Kush and i use it still in flowering and in veg......... but when you get a CO2 tank and regulator it gives you a guide of how much to release in your room pending on your square footage........ so for my room i turn all my fans off and turn my tank on for 14 minutes and shut off and with the light on let it sit for an hour.......but ive been tampering with the timings now so ive been extending feeding and etc.....but thats a personal choice........and ive heard of people feeding in darkness but i figure why are you feeding the plant CO2 when the lights are off and there not feeding for it........also when you feed your baby CO2 you need to have it feeding it to them above the top of the plants (canopy)...................and i fed them when there on 24 hours of light about 4 times a day with CO2 but i got the time to.........but getting a timer control for your whole room would relieve that....but good luck Dying i hope i helped

ok thanks man appreciate it alot

So bubba u dont have your line from the regulator to the back of a fan to disperse it evenly?

i been wondering about this also. ive heard only flower is ok, though its optimal if you do it both veg and flower. im pretty sure you only use it when lights are on, but if that is the case, does this mean use it 24hrs a day while on veg and 12/12 on flower? any experts care to chime in please?

someone needs to write a c02 tutorial lol

i was using it on the back of the fan and then i started tweaking on on it..........and have 2 oscilating fans in the room plus its closed off and i like seeing the difference in my monsters
