I think if your environment is good there’s a big margin of error for bud rot. If you’re inside & your humidity is under control & plants have room to breathe u should never have rot, but there’s a point when they don’t get any better supposedly. If you’re growing outdoors in a rainy fall climate u will harvest early or you will get bud rot. I grew outside for 3 years before and learned a lot about environmental stress & bud rot.
