dwc and humidity levels

hey RIU just a few questions ... running a dwc set up in a 30x30x72 lights on humidity I can get humidity and temp at 50-60% 77-86f depending on weather conditions outside. but with lights out morning cab humidity is in the 70's and I'm just concerned about issues with mold in the final weeks.. i think my room might be a little small for dehumidifier it would be running in a room outside the area...

any thoughts? is this normal running a dwc and at what humidity levels would be at the highest risk? is mid to high 70's a concern?

Thanks Every1

is there any ventilation at all during lights off?

for flowering 60% humidity is the highest you really wanna go.
The higher the humidity the more transpiration slows down.
Get some fans. Moving the air (24/7) will drop your humidity, and keep your buds dry.

yes vent on 24/7 400cfm no filter on just pulling air out, and 3 4inch fans to move air around as well... but the lights off humidity still increases quite abit.
