I read today that High times stated in some issue that using Co2 in the last 2 weeks will reduce potency and shouldnt be used. I run a perpetual and just installed my CO2 boost system in my grow tent. Can anyone comment on this?

i would like to know as well. I am running perpetual and the guy at the hydor store said NOT to use it. I have heard many conflicting ideas.

I've always focused on reducing the humidity down as low as possible during the last two weeks, which pretty much never lets the C02 turn on, as the exhaust is always running. I know a dude that runs his c02 as much as possible and his grows turn out just fine.

Why don't you post the source where you read this. I'd be very surprised if this is true. The potency of the plant is genetic - not something that can be increased or decreased due to environmental controls (nutrients, light, water, air, etc.).

I looked for info on using co2 for marijuana and I kept finding the same information over and over and it remarks at the end that high times said not to use it in the last 2 weeks because it affects potency. I can't see how it would either.
