Features 6

  • 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. The 24-hour timer function can reduce energy consumption; Three modes can be freely switched; The automatic defrosting function can effectively prevent the machine from frosting, ensure the normal operation of the dehumidifier, and extend the service life of the machine
  • MONITOR AT ALL TIMES: The humidity setting of this dehumidifier can be adjusted from 30% to 80%. Once the target humidity level is set, the dehumidifier will automatically stop when the target humidity level is reached. With the sensor probe installed, the dehumidifier detects the humidity around the probe and displays it on the screen, allowing you to monitor the humidity inside your tent at all times
  • TWO DRAINAGE METHODS: When the water tank of the dehumidifier reaches its maximum capacity, the full water indicator will light up and sound an alarm to remind you to empty the tank; it can also be emptied directly through the drain pipe to prevent water from overflowing out of the tank. When the water tank is full, the dehumidifier will stop automatically, and the dehumidifier will restart after the water tank is emptied

Awesome product!
Model: SF-Dehumidifier
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
Reviewed in the United States on December 21, 2024 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!

Poorly programmed and causes issues.
Model: SF-Dehumidifier
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. ... show more

Solid Dehu
Model: SF-Dehumidifier
This unit does need to sit for 24 hours prior to first use but when you begin using it, it is really nice. Works well with the ac infinity control plug and the ai controller. I used it to dry and on continous all day it had to be emptied once per day. Does have a spot to hook up a hose so thats also nice. Good product. ... show more

Spider farmer products are amazing
Model: SF-Dehumidifier
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. ... show more

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.

MAJOR DESIGN FLAWS DONT BUY
Model: SF-Dehumidifier
This is actually a very very and I do mean extremely POOR design anyone trying to pull real humidity out a room using the drain will be fighting an up hill battle like wow 🤯 what a HORRIBLE design. Let me explain the drain port is in the back like all other systems STANDARD butttttt the air port that pulls in the air is also in the back and since the drain hose is so short you can’t place the air port in the front to pull more air you are absolutely 💯 forced to place it up against the wall which seriously 😒 restricts the air flow going in just an absolute joke for a $200 dehumidifier seriously 😐 how stupid is spider farmer to design a dehumidifier with such restrictions on the air flow coming in almost all others pull air from front to get more air flow so that way the user can actually control the REAL HUMIDITY this is a massive scam. FYI the drain hose is tiny I mean epically short tiny hose how can they even classify that as a drain hose and its corrugated so it actually holds water in the drain tube as well will be returning product soon 🔜 just a low end product with HORRIBLE design FLAWS and I mean 😢 major design issues. FYI I have it sit on 40 humidity lowest it can get the 8’ x 8’ room to is 70 RH um like what the actual heck and it’s on continuous run as well and can barely 😰 get the RH to 70. Just a low grade over charged product with massive design flaws HUGE design flaws MASSIVE like it’s a joke to the customer it’s like SPIDER 🕷️ FARMER is suiting at the BANK 🏦 laughing 😂 they butttttttts off at every single customer knowing how bad they have screwed the customers over ... 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

Won't turn on after 2months of use.
Model: SF-Dehumidifier
Works great! First one died on me but Spider Farmer replaced it quickly, and the new one is working like a champ. Keeps my 8x4 tent with 6 plants at ~50RH down from ~70 outside the tent.
