Autos and photos?
or the humidity difference?
Autos will flower on an 18/6 cycle
Photoautotrophs will only flower if they receive a minimum of 10 hours of uninterrupted darkness.
I like to keep my humidity at 50-60% for veg and for clones more like 70. Flower you want it low or you’ll have to face the almighty powdery mildew.. around 40-45%
And I’m not an expert I’m a noob but I’m very diligent. If I’m helping you don’t be afraid to give me a like or something I’m trying to earn some stripes around here
