Humidity Problems inside the Canopy

I have been looking at two wireless hygro meters and they've been around and under 45% till I found a bit of pm ( powder mildew) so I bought one more meter and put it down underneath the canopy and sure enough the meter now says 48% so its probly at around 50% were im seeing the pm. Can anyone assist me in what to do as I am getting tired of spraying neem oil

Y dont u just put in a dehumidifier

I have one in there and it keeps the humidity down outside the canopy. Not sure why its not working inside the canopy

I would try it inside the canopy. Or maybe alternate it.

I've been using neem oil for pm for a long time and it's very difficult to control, it keeps coming back. I was told that Potassium carbonate works great and read that milk also works but didn't try them. I'm giving the neem oil the last chance, I'm spraying every 7 days since the plants were small and see if it really works or not.

Also moving the air inside the box is meant to be very important.

Good luck

If the air is not being moved around and through the canopy, the dehumidifier has no chance to control the Humidity in the room. Now that summer is coming here, I can't run my dehumidifier as it generates too much heat which can create new problems.

use a fan to move the air around get an a/c to combat the heat of summer. Since i purchased my dehumidifier the pm has gone away i spray greencure on the pm from muckboots.com. I run my dehumidifier on auto at 30%-40% 24/7 that will get that m it did for me.
