Mold, harvest?

I'm about to have a straight week of rainy days, and my two NYC D's plants were planted late so they have a lot more potential bud.
The problem is, that after a week of straight rain, i'm worried mold might develope, and in a week we might be getting our first frost anyways. so shoudl i just harvest now?

Go out and sake um off then spray them with sodium bicarbonate .

yea try and give them a good shake like delstele said get the most water off it as you can and spray them with the SB. otherwise your bud will not be to its full potential and you will regret it if you pull early! the last week or two the buds really swell, the trichs go crazy and mature, and you get denser heavier buds.

Sodium bicarbonate? Where can I find some of that. it wont interfere with my organic grow will it?
