my humidity is currently 65 during flowering. im on day 26.. my question is, is the humidity to high for flowering? and if it is, how long before mold starts to form?? Also, does mold form faster when its warmer than colder. its about 60 degrees in my grow room.. will this stop mold from forming?
? about humidity..

65 RH is too high in my opinion. I keep mine at 35

yea mate the higher u have your humidity levels and your temprature the faster mold grows. perfect temp is 24 degrees C dont know what that is in F. people say that 60 is a perfect RH but i would keep mine at around 45 - 55 to be safe.
our kinda plants love humidity and will grow better im higher humidity however they attract mould especially during flowering. i try and keep my RH at 40-50 during veg.
put a dehumidifier in your room. you can buy ones in the shape of an icecream container from various stores. (usually cheap chinesse shops) im a New Zealander so i dont know what brands you guys have. ours is hippo

What size grow room?
Is it sealed, or are you exchanging air to outside?
MJ needs a lower (below 55% RH) in flower for 3 reasons.
1) To prevent mold
2) to increase resin production. At lower humidity levels, the plant excretes
more resin as a defense mechanism to help it from getting too dry.
3) To promote better transpiration and uptake of nutes/water.
