  • 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.

    • Does a great job
Model: SF-Dehumidifier
Spider farmer makes pretty good equipment and this one is up to. Par it doesn't make a lot of noise and removes the moisture from a4x4x8 tent with no problem just don't forget to dump the bucket of excess water (from A separate bucket) as needed.

    • Very power efficient!
Model: SF-Dehumidifier
Keeps my basement humidity at a comfortable 55% on the low setting, best part is that it only consumes 270 watts on low!

    • First one didn’t function
Model: SF-Dehumidifier
As of right now, I have to give it a one star the original box had Styrofoam and stuff in it, but the Amazon box didn’t have any. It was just a box inside a box took it out and it won’t even function like it’s supposed to. The dial is stuck at 25 as soon as you plug in the ethernet cable to hook it up to your controller it just completely stops functioning I looked up and this is a common issue that I don’t know if a sensor on the inside of the machine is broken and dealing with their customer service is not the greatest. You cannot call them only email. For a brand new unit coming and it already can’t be used brand new out of the box and has to be returned. Doesn’t give me high hopes for this dehumidifier in general. And some of the reviews even state that it doesn’t help their tent situation out very much in general. As of right now, it’s a one star review if the second unit arrives and it actually works and performs like it’s supposed to. I will change my review but as of right now, I would not buy this. ... show more

    • Great product, except…
Model: SF-Dehumidifier
This thing is a workhorse! I use it with my 4 X 4 and it works great. My only issue is with the quality of the vent adapter that goes on the output for those of us that prefer to keep it outside the tent. The plastic tabs that connect the adapter to the unit break very easily. Mine will no longer stay attached to the unit. I could think of a dozen alternative designs that would be better than this one. But…I’m just an end customer so what do I know, right? If anyone out there has a hack to keep a broken adapter attached, please share! ... show more

    • Awesome product! Awesome product!
Model: SF-Dehumidifier
Review Image by Mandown gardening I bought this humidifier and it has been a great addition to my garden. It has a hose that is adjustable to move to wherever I need to move it at that part of the plants life. I can also adjust whatever level I need to have of humidity at that time for the plants cycle! I highly recommend this product for any beginner or novice grower! A great toll to add to your arsenal!
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. ... show more

    • Works well but not ideal
Model: SF-Dehumidifier
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. ... show more
