Revenue lost to bud rot

it can be missed until the very last day and discovered only during harvest and trimming.
keep your relative humidity low (40%) during mid-late flower. May want to invest in some UVB lighting as well.

 

If I were a commercial grower, I would be checking for this a lot. Commercial cannabis is regulated and requires testing; if they fail the testing (ie. presence of mold) the cannabis needs to be destroyed, so I'd imagine they are on it.
Here's a couple articles:

and for using UVC vs mold

I spend a hour a day with my plants not gettin by me when growing outdoors. Isn’t a prob indoors cus I’m n full control of environment

 

Actually, I rarely see mold or pythium issues in my facility.
Well… ok… so I did see some mold blossoming high up in the corner of my attic space due to some poor circulation and condensation issues after a serious sub zero cold snap. It was dealt with, and I washed the two consecutive runs with a solution of hydrogen peroxide just to be safe. Everything tested out just fine.
I live in a fairly arid part of the country though, I’m sure it’s more of an issue for my cultivation brothers south of me.

 

This time of year Pythium mold is a big deal, I'll expect to loose anything form 1/8th to 1/4 of my grow to molds

my defense is neem oil and keeping the plants very dry indeed
even foliar feeding water in the extreme to the fans only

and dipping the whole tree in a bath of air temp water and bleach or peroxide
dip again to wash of the chems,allow to dry in front of a big fan or strong wind
to avoid this ...grow smaller plants but more of them?
good luck
