Hello guys,
This is my first message here, I read as much as possible on Wietforum using Google Translate.
I come from Opengrow where I log as Provence.
I apologize for writing here in english.
I prefer to ask dutch growers for this question.

QUESTION
I have good temperatures in the tents troughout the year without using electric heaters.
The big problem comes from the humidity levels during automn and winter. 75-80% humidity.
Plants can't make evapo-transpiration efficiently so they take longer to mature and last time I lost a good part of my harvest to mold.
Do you guys supply plants with outside air for gas exchange ?
I suppose you use hygrostats ?
What models do you use ?
I'm done with the climate controllers. I've tried the "Step-controllers" Temp+Humidity and I returned them to the shop.
Expensive and real crap. Never worked efficiently. I either had good temps or good humidity, never both together.
My feeling is that at certain periods of the year, I either have to
-give up on optimum CO2 levels in the room or
-deal with too high humidity
I guess someone here already had the same problem and maybe found a solution...
Thanks a bunch for reading
You have an impressive forum and good growers that's for sure
