My greenhouse has humidity levels of over 90% in the early mornings.... already found a little bud rot on my granddaddy purple...had to cut a few buds out. I now have 2 big box fans running on that plant. Is there something else I can do to bring it down? Will the humidity levels in the morning get lower as September rolls in? At this point I’m gonna need like 20 fans blowing in there lol
Those leaves turning purple might be temperature related depending on the temp at night...
I put this exhaust fan on the end of my greenhouse,it keeps the humidity the same as the outside. If your humidity outside is high 90% it might not work.
