Mold during flowering (basement grow)

I've had trouble with mold attacking buds in my basement grow. It only happens during flowering when the buds grow to decent size. I need to gt a humidity gauge an possibly a dehumidifier...

Is this what I need?

Try "Rot Stop" spray or something similar. And get on the case ASAP,you could lose a huge amount of bud like this, and the rot is often not visible from the outside.
Yeh a dehumidifier will help for sure, but man get spraying!

i don't know about products that you spray on buds, i'm very wary of 'stuff' on the buds, might be OK
if you can reduce the humidity, that's probably better, not sure how practical it's going to be in a basement, basements are damp and changing that may not be practical
there are strains that are supposedly mold resistant, but don't have any that come to mind

dehumidifier, and and and a thermo/hygrometer so u no its not too dry, basements tend to be pretty damp

Run fans so plant's leaves move in airflow 24/7. Since i did this ive had no mold and i grow a mold risk strain.Get a hygro meter so you have more idea when plants are consuming quicker than normal with extra evaporation. (very low rh).
