How Far Into Flowering Do I Use Co2?

[jammie]

i'm at week 6ish of flowering. one strain goes 9-10 weeks and the other 12. at what point does co2 loose its effectiveness? stopping would also help drop my humidity. thanks for any advise

I follow the VPD chart until week 6-7 then I cut co2 the last week of flower and drop my humidity to near 40%

I run 1000ppm from.flip to week 8, I run 68 day min runs). Last 2 weeks I drop ppm to 500. Temps also get dropping, which also drops my rh to about 50-55%.

Thanks for the quick replies guys. Exactly what I was looking for. This has been my first co2 grow and am impressed with results. Got some pretty dense buds and don't want to risk bud rot
