As i said in the forum before im growing near the ocean on a greenhouse (only top and front is covered )
during the day i get 50-60% humidity but during the night it raises to 80-90% my plant just started flowering yesterday, it is on super early stages
Ive had no problems so far with mold or anything really, im a bit concerned that i could get some mold during the flowering stage , any advice on this one , should i be concerned ?
In the past ive only grown a few auto flowering on the same weather and never got mold, but this time i have 2 big plants and i don't want to risk it
thank you guys

IDK but I have an oscillating fan out in my garden right now because I sprayed BT and there was no wind to dry them lol, Gonna move it for the 3rd time tonight in about 5 mins.

I think most outdoor growers along the coast has the same problem in a green house or not . The later it gets the damper it gets there will be mold just hope it not to bad that you can keep it trimmed off ihave seen plants go to shits in a couple days at the end of this week i an going to have to deal with a hurricane it seems it is something different every year . I can’t move them inside so am going to wrap them in netting and lay them down if i can .

Yeah I was thinking on adding some fans maybe on late flowering specially at night

Salt in the ocean air is less favorable to mold. I live inland in the southeast, a commercial dehumidifier is a must. I run 40% RH at night. I would at the very least get some good air moment with fans and thinning out some foliage. Thinning out your plants will actually help lower humidity all together if the greenhouse is completely enclosed.

Correct me if I'm wrong, but isn't there plenty of air movement near the coast? I've only visited the ocean coast a couple of times, but there was always at least a breeze. Something similar happens on the shores of Lake Ontario (really a freshwater sea). Has to do with difference of air temp over land and water and the differences in air pressure that causes.
Plenty of air movement would help prevent mold and fungus.

Yeah Maybe opening the green house, but I guess you want the warmth and greenhouse effect so that may not be an option. Extractor
Fan would work but probably not what you had In mind. So I guess yeah thin em out and pray lol.

The water here is pretty salty ,

Yes , most of the day there is breeze and fresh wind.

My greenhouse is not finished yet , it's opened on both sides , weather is hot I like south of San Diego , there is wind and breeze passing through it the whole time.
My nephew grows about 900ft from the ocean on El Matador state beach no problem
Here the humidity seems to be constant , in socal it feels like the summer just started , does he grows outdoors ?

Thanks for all the answers guys !
I attached some photos so you see the situation and the babies.

More air flow the better. As long as temp and humidity good, cant have too much
