I live north of Albany NY, and it's been 70s and 80s all month and the month before, the lows are in the 50s to 60s and it's been overcast or raining constantly.
Sun does peak through the clouds now and again, but as for my plants they are not suffering at all, they are loading up like nobodies business.
The rain actually helps with polination, rain drops slapping the tops of the flowers and knocking pollen onto the stamen.
I'd like the weather to be more sunny, but I cant complain.
