too much co2????????????

can you mess plants up with too much co2,say 2-4 homemade co2 2litre bottles in a 5x3x3 gro box??thanks

bumper ................

Yes you can. I think you can buy a C02 PPM meter, try to stay around 1200-1500 PPM.

Trust me if you are using home Co2 2 litres, there is not enough Co2 to mess with the plants. Marijuana loves Co2 and my friends have kept their Co2 burners upto 2000 ppm with no problems.

^ what he said. you would need at least 15-20 2 litre bottles to get the c02 to 1500ppm.

cool thanx.....
