I’m struggling with humidity a little bit. The humidity for the past week in my area has been around 90 %rh so it’s been insanely humid out. The la dies are in a 2x4 tent in my back garage. I have a 9 in osc fan, 6in vivosun inline fan for exhaust, and a ac infinity booster fan to pull air in at the bottom. I’ve been just trying to get the air flow as much as possible since the insane humidity. I have a very small vivosun dehumidifier in there now. I tried 2 different ones and I’m honestly not happy with either. So I’m just looking to see if anyone has a dehumidifier they think works great or even decent if i can get it to be in 50 range I’d be happy , I’m looking to spend less than 100 if possible. Thank you
You will never get that humidity down to where you want it with that constant intake at 90% RH. You have to create a closed or semi-closed system in order to do that. Those humidifiers and de-humidifiers are designed to do a small space with for the most part static air or low volume. A de-humidifier is nothing more than a small air conditioner, the coils get cold and condensate out the water vapor in the air and deposit it in a reservoir the heat must be directed somewhere other than your tent or it then causes that problem. Your best and most lasting solution would be to install a window AC unit in the garage.
This is why I don’t grow during summer time, to much heat and humidity. you can grow outside and yes its possible to grow indoors but IMHO unless you have a space purpose build for growing plants indoors, its extremely difficult and costly thats not even including that most electric companies charge more during summer “peak hours” for me that’s .23$ more a kilowatt hour. may the odds be ever in your favor.
Yes, agree, I have the perfect setup, didn’t realize it when I bought the house, but my old coal room turned into the perfect grow room, I put 2x12’s top bottom and sides and R22 insulation completely. The hot air is exhausted outside in the summer through the old coal shut that I converted to a multi pane homemade window with a duct, in the winter I can duct it out the wall of the coal room to heat the basement for free with the heat from the light. They only negative is it is kinda small, and I also have my office in it as well. It is 16’ long and 6.5’ wide after the framing insulation and drywall.
It’s in the mid and high 90’s here now, and here is a pic of my tent controller, I am currently in the drying phase of my last grow.
Very nice and lucky. Sometimes things just work out. I’m going to be popping seeds sometime next month so by the time the clones are ready from them the temp/humidity will be more easily controlled in my space.
I have three. The best one I got and it is huge. I got from Goodwill and it was brand new. Got it for $35 I believe. This was back during 2020. The other two I have worked excellent also. They just pull a little bit too fast. But I guess if I had to suggest one. It would definitely need a greenlight. And a place to hook the water hose up for the drain. Now, when my plants are a certain size, I don’t use the water hose. I’ll let it fill the tank up. That way it fluctuates. When I’m trying to get out, I’ll run that dehumidifier and try to dry my containers out but yet I only want so much at a time. I want to see how much is pulling out when it’s just starting veg time and flower time. For me at the end, I run my humidity very low. Some people say it it’s too low. But if you ever lost your entire crop the bud rot you might change your mind. But everybody’s grow different. Everybody’s places different. When I lived out west it was so dry. We never used anything.
If you’re looking for a dehumidifier recommendation, GrowersHouse has one of the broadest selections available for both hobby and commercial cannabis cultivation. They stock premium brands such as Quest, Anden, Santa Fe, Ideal Air, and Active Air.
For serious flower rooms and light-deprivation tunnels, Quest and Anden are excellent choices because they are designed for continuous 24/7 operation and are widely used in commercial cultivation facilities. Santa Fe units are also highly regarded for their energy efficiency and reliability, while Ideal Air and Active Air offer more budget-friendly options for smaller rooms, drying spaces, or curing areas.
One advantage of buying through GrowersHouse is the after-sales support and availability of replacement parts, including filters, duct kits, pumps, and mounting accessories. Having access to spares locally can make a big difference during flowering when humidity control is critical and downtime is not an option. For a commercial cannabis facility, I would personally shortlist Quest, Anden, or Santa Fe as the primary dehumidification solution.
