My first exprince with CO2

whats up fellow growers, been awhile since i've posted and searching for some answers i haven't been able to find about CO2, i've read through the forums and even got two books on it : "Gardening Indoors with CO2" by George F. VAn Patten and others, "CO2 Temperature & Humidity" by D. Gold, edited by Ed Rosenthal.

somewhere i read, or thought i did, that you want to stop co2 enrichment two weeks before harvest or the plant will think it still growing and not finnish properly, true or false? or your thoughts on that.

there is 60 plants total, 1/4 is purple kush, every thing else is purple berry, and two chem dogs. basement that was panda plastic'd off to 12x10x5.8, details on what i'm running on the pics.

this is my second run in this room, first was with out co2 and was mostly purple kush, some berry's, and one banana kush, harvested about 2 pounds. co2 levels never topped 210 which is i think it was so light, amongst other factors.

Experience

One last thing, NO Co2 during the last 2 weeks of flowering, it signifigantly delays maturity because it displaces the acetylene gas the plants produce to signal ripening of the flowers.

so is this fact, cuz so far thats the only place i've been able to find it.

so after rewording my search's, i found about 5 sites with the same advice. so i'm going to roll with it. but was thinking if may be it would be a good idea to set my co2 for 300 since it lacks with no co2. or will it have the same effect and and displace the gas it needs to mature?
