CO2 Help

I have a co2 issue. Anyone have a link to the do's and donts on Co2 I would like to know how long to use it and when to start. I am going to start a 2 week flush starting next monday and I am using co2 at 1500ppm at the moment for one week. is it going to make a difference? I have a cap 1 gen and IGS100 advice please help.

C02 can be run from veg to harvest. it increases size and yeald of plants 1500ppm is perfect. while 1 week might help a bit, you should run it the whole life of the plant. over 2000ppm is bad, 1000-1500ppm is good too much 02 will burn your plant, but I have had ppms reach 2200 for short periods with no issues. again 1500 is the desired max. do a search c02 and marijuana and plenty of great info will come up.

thank you very much it seems like everytime I ask about Co2 not many people are willing to answer
