temp and humidity fluctuations in the flower room

my humidity swings from 35%-60% and I don't know what to do about it I got a big 7000 SQ ft dehumidifier with auto defrost but when it defrosts it makes my humidity skyrocket what to do?

Humidity can be tricky to accurately control considering healthy plants are natural humidifiers. To give helpful advice, one would need to know more information such as the layout of your grow room. Where is grow room located, as in stand alone or inside another structure? What climate is your area, desert, tropical or...? How big is the grow space? How many plants and at what stage? What method of growing are you using?

Yeah lots of questions but not easy to constructively comment on the unknown.

Can you put the dehumidifier outside the grow space so defrosting operations do not effect it?

Also I wouldn't consider the RH swings of 35-60% to be detrimental to the plants as long as it doesn't dwell at any extreme for too long.

so i'm talking about my flower room so all the plants are mature 4ft tall or so I run about 20 plants at a time I'm growing in a mobile home in one of the bedrooms my room is 12x12 and i'm not using tents I'm growing in soil with7 gal pots with organic nutes and I'm in Missouri so humid in the summer I don't know how I would vent the dehumidifier through the wall but that's a good idea if I could figure out a way to do it

Idk why it would frost to begin with, are the temps getting too low? Maybe could warm up the space around it as needed. I use two smaller dehueys 1500sq ft capable each making 3000sqft worth power. In a 10x10 but I use tents and less plants so only take up 2/3rds the room.

Just looking up reasons it can do that sounds like theres an issue with that. I have like 5 dehueys I play with and just never had one frosted even being past due to replace it. What kind is it? Sounds really oversized. Mine already is but Ive never had that. I dont go below 58F ever really tho.
