I would say you are at risk of mold with himidity that high. I know there are products out there you can feed the ladies to reduce mold, I'm not sure what they are but I was reading about them earlier, just forgot the name of them.

A dehumidifyer is probably a good idea, have read that a lot of people also use the water they collect to feed as well. Also the denser the buds get the more risk there is.
