I'm on day 24 in flower, did some defoliation during the vegetative period and a quite heavy defoliation on day 22. I'll do some light defoliation if necessary up until around day 45 and then I'll defoliate heavy again. I have CO2 tank, but it only lasts ~2 days and I can only afford to refill it once, so I'll add extra CO2 for 4-5 days When is the best time to do this? Everything else is dialed in and looking good. Thanks in advance.
