My grow conditions are living in the Washington, DC area which is known for it’s high humidity during Summer. I am growing in a 12ft x 25 ft shed that is unheated and no A/C. Ventilation comes right from the outside on the North side of the shed since this is the coolest. I am using a 3 x3 ft AC Infinity tent. I am growing auto flower and expect them to start flowering in the next 2 to 3 weeks. Already I am starting to have high humidity problems and high temperatures of 87 degrees. My question is will a nice 50 pt dehumidifier reduce the humidity enough to warrant the expenditure? Anyone with similar condition who is successfully using a dehumidifier, it would be appreciated if you share what type you are using. Thank you.

I flower in a 12x8. I live in the south and fight humidity problems constantly. I ended up finding a good used one on Marketplace that works for a 2600 sq ft house. I keep it in my flower room. Keep in mind though that it will throw off heat when running and might have to turn up your exhaust to help expel the extra heat.

A humidifier would help with RH but most allways will also increase heat in the process of removing the moisture. I can’t run my dehumidifier without also running a AC to counter balance the temps and RH.
There are things like some portable AC units that dehumidify aswell but they can be pricey.
My understanding of transportation rate is with higher temps a higher humidity is better but obviously there’s a line where once in flower that higher humidity is dangerous if dew drops form and remain on buds.

Unless your shed and tent are totally sealed, you’re probably gonna be running your dehumidifier a lot. It’s just going to pull outside air.

I’m on the southern coast, more or less, and high rh has been killing me the last two weeks. As soon as I flipped it goes from a constant 40% to 60% avg.

You need a good dehumidifier @Patcubed but they put out a fair amount of heat. I have to run the AC more to compensate.
