Co2 Schedule

[ForrestGUMP]

I can't seem to find a straight answer on this. I'm just looking for feedback on how long you guys use CO2 and at what levels. I'm 30 days into flower and I've been keeping it between 1200-1500 ppm.

Thanks!

I replenish once per hour to 1200 ppm during lights on weeks 1-6. Week 7 900, week 8 700, week 9,10 -600.

Keep it at desired level all times during lights on. I love my fuzzy logic controller. Set it and walk away. I'm playing around with co2 ppm as the weeks go. I'm trying out 1400 from flip to week 4. 1200 week 4-7.5. 500 7.5 to chop (64-70 day runs?

Usually done about 60 days. Thanks for the advice! I'm gonna bump it down a little to 1200

Fuzzy Logic co2 ppm monitors for tanks are the only way to go with co2 supplemented rooms. And with burners..just turn ole Fuzzy off. In my opinion anyways. Back in the day these gadgets were unheard of and we used the ole timer method and the goofy boxes that controlled the vent fans in conjunction with co2 release. The boxes from Green Air and CAP. And it was all a guessing game at best. Wasted many a tank that way. With a Fuzzy Logic/tank co2 and sealed room...I started to truly get the 20 or 30 % increase in yield that we never got but thought we did in tje olden days. I remember when the co2 ppm gadgets first came out and they were like a grand or 1500 bucks a pop. I waited a little while and scored one for about half that. Now they are even cheaper. But yeah..these are the way you want to hook up a co2 system for sure.
