Has C02 Postponed Your Harvest Date?

Have you noticed that c02 delays your ripening/ extends your projected harvest date ?

PPM?
Bottled or Generator?

Co2 prolongs harvest because it inhibits a hormone called ethylene which triggers ripening in c3 plants.
I know what ethylene is. Ethylene is the flowering hormone, produced during the dark cycle and interrupted by light exposure, tending towards the shaded part of the plant in light. CO2 is still required for proper flowering and respiration.

Maybe check the burners, incomplete combustion from a faulty burner or lack of oxygen will also start producing ethylene by itself.

Ethylene is specifically a ripening hormone which is mainly present in gas form. It can also communicate with other plants through the stomata telling them stress levels are high. It isn't the presence of co2 that's the problem it is the unnaturally high ppm levels that inhibit the ethylene production......

none of us are really having this issue but it has been raised as an excuse for "why his plants wont finish properly" and I thought that was bunk. I use c02, must be the reason mine always finish on time I figure
