- UNIQUE DESIGN FOR GROW TENT: This product equips with an air duct so that the dehumidifier can be placed outside the grow tent without adding heat that could affect plant growth. This unit suitable for 3x3, 2x4, 4x4 ft Tent
- HIGH PERFORMANCE DEHUMIDIFIER: This dehumidifier can remove up to 32 pints of moisture (Under 95F, 90%RH) per day from a room of up to 2000 square feet.

Has been chugging away and removing excess humidity non-stop for about 8 or 9 months with 0 issues. Highly recommend this! Great quality! Spider Farmer is great!

Is ok but suffers from same issue many humidifiers do. It works fine but if you use the automatic mode, which most will, it doesn't cut on how you set it. If you set the humidity to 50, it will bring it down to 50, but then wont cut back on until it's at 65 humidity. If I wanted 65 humidity I would have set it to 65, not 50. Save your money this isn't programmed well and the customer service is non existent. Was going to give a 2 star review but they tried to block it, so 1 star now.

I bought this with my mister; I ran this product my last harvest. I couldn't tell it was on at first cause of how quiet it is, It pulls moisture down to ideal humidity really fast so you don't have to worry about it. The design is amazing I have it ran to drain out into my sink in my growing room. Was worth every penny.

This unit works very well, like how the design let's you sit this unit outside your tent saving you a lot of floor space. (Talking to you 4x2 tent growers like me) It grabs the outside air and dries it before blowing it into the tent. The included sensor (That you hang inside the tent) is what helps the unit automatically turn on and off when in use. What I really love is that it works well plugged into a smart plug. The settings are set out. I only run this during the lights off schedule. My only complaint is the air outlet hose is a little thin, you can see light coming out of the tent which is a little discouraging. Wonder if light leaks inside the tent when the lights are off. Currently looking to replace the hose for a thicker light proof like what Infinity offers. And it would be nice if the wheels locked. But all in all it does the job very well! No drain hose to a bucket needed for my 4x2 setup. The built in catch tray is enough to hold a couple weeks worth of use for me. Perfect.

This is a perfect small unit which is very quiet. Set up was easy and quick. I was concerned about not having a way to calibrate the sensor but just noted the difference between a calibrated hygrometer and this unit. No issue. I purchased a 20 foot hose to run from the unit to my drain. No issues.

It technically does its job and pretty well but some major design flaws. For me the biggest flaw that doesn't get explained well in the description or reviews is that the air blows OUT the hose. I would've thought it would be better to have the air sucked out of the tent through the hose. Since the air blows out the hose, if you have the unit outside the tent as advertised, it's really just blowing dry air into the tent to lower the humidity, I'm not sure I would call that "dehumidifying". If I want to dehumidify and blow the air out the tent, the unit has to go in the tent and I don't have room for that. I specifically got this because I don't have room. This flaw also causes positive pressure in the tent because it's blowing air in faster than my exhaust can remove it. I can turn the exhaust up but then it's super loud. Not ideal that I have to choose between smell escaping the tent and a loud exhaust. Second, the sensor probe is way off. Compared to the AC infinity probe and the other 2 hygrometers in the tent, it's about 5% low. Third, the increments of 5 on the humidity setting are annoying. It would've been a simple decision in the product design process to program the controller to work in increments of 1. Thankfully it does have an auto restart feature that lets me use an AC infinity plug to connect this up to my ACI controller. Overall I would recommend this ONLY because AC infinity hasn't come out with something better yet. As soon as they do I'm getting rid of this.

This is a very nice product. When I put the ducting in the 6in vent hole it kept my tent at what i set it at on the unit. It's on wheels so it makes it easy to move around as well and is user friendly. If I were to change anything on this it would be its water catcher I would make it just a little bit bigger but it does have the hose you can put in a bucket for continuous draining capabilities. It's a great tool to add to your garden and I highly recommend it.
