Tommy716started grow question 2y ago
So I've been adding CO2 to my tent. Is that 1313ppm too high? They're in the third week of flowering

1200-1300 ppm - i've heard varying values on "max" ... if your vpd, light and fertilizer are not dialed in to match it, it won't matter -- it won't be fully utilized is the better way to say it. Further off that stuff is, the less effectively it can use all that extra Carbon.
think bugby has some video on it?

Early Amber TrikesMystery strain, pretty sure its Strawberry Cookies https://supersativaseedclub.com/cannabis-seeds/strawberry-cookies.html#/26-seeds-3_feminized_seeds Hairs are still yellow but trichomes are mostly opaque with 5-10% amber. Harvest now or will buds still swell/ripen?

Does it go against community standards to inbox someone who replied to a grow question? 280 characters isn't enough to describe all problems. There are so many experienced growers here that if we could actually talk back and forth it would be so helpful but I can't figure out howWeek 7
