High humidity in early flower

Hey everyone.

I'm in the middle of my first grow. I cool the grow room using outside air. I have a fan sitting on the window sill pulling in cold air, which is plugged into a wall socket that shuts the power off to the fan once it gets too cold and vice versa. It keeps the temp in a good range.

Lately it's been raining a lot so humidity is often in the 60% range, sometimes higher. Plants are on Day 14 of flower.

I'm wondering when mould really becomes an issue. It's going to get quite a bit colder in the next month which will drop humidity a lot, and this is what I'm banking on. A dehumidifier won't really do anything with my setup as the air in the room is circulating too fast from outside.

I will address this issue immediately if it's really necessary, but can I get away with humidity spikes every once in awhile for the next little bit or will the flowers start moulding before then?

I had humidity problems 50 to 60% even with damp rid and I didn't have any problems during flowering with mold. Just harvested my first grow and getting ready to start my next. So yes, You can get away with it.

i doubt spikes of 60% will hurt you as long as the air gets circulated regularly

Thanks. I definitely have a TON of circulation. In addition to the fan sucking air in the room, which gets pulled out of the house by cross-breeze from another window I have open, the tent I grow in has a 450cfm inline fan recirculating the air every minute or so in the grow space.

I will still work on lowering the humidity, though. Can't believe I'm saying this, but bring winter on. Nice and dry
