* update. Kinda feel like these are way to easy to damage if you get it wet. Are the electronics even sealed? My current unit just died after it decided to overfill the lower tank for whatever reason. I mean it’s just plastic “trigger” and spring. I guess it got stuck. Screen fogged. Unit died shortly after trying to dry it out as i cannot return it. Previous unit ordered did not align with the base properly and would not even dispense water into the lower reservoir. Overall, questionable durability. Switching brand. Thankfully AC infinity make better units now. (* original review) Nothing fancy, but it’s better than using a reptile humidifier. The larger capacity is welcome as well as the increased mist levels. This humidifier is much better than smaller units i had been using. I don’t use the built sensor. I agree that it doesn’t appear to be very accurate, but i use and would recommend you get and inkbird and move on with your life. Much more capable and accurate than any built in meter and it will also control your dehumidifier. The spider farmer humidifier is fully compatible with external controllers since it has recall for all of the previous setting before power is cut. I’ve been using this unit for just about 6 months and it seems much more durable than reptile versions as well. Great machine. Plenty of humidity works well when others haven’t. I’ll be trying the 16L version for my large tent next.

Worked for 3 months then started pushing mist from the bottom of the unit. I gave it a good cleaning and it worked for another day or two before doing it again. What a waste of money…

Let me tell you, the Spider Farmer 3-in-1 6L Humidifier has been a serious upgrade to my grow tent. I've been through a lot of gear, and this one has quickly become a staple in my setup. All-in-One Wonder: This thing does it all—humidifies, monitors temperature, and checks humidity. It’s like having an assistant that actually knows what it’s doing. I love that I can keep an eye on everything with one piece of equipment. It’s made dialing in the perfect environment so much easier, which my plants are definitely appreciating. Big Tank, Easy Refill: The 6-liter tank means I’m not constantly running back to refill it, which is a lifesaver during those long flowering days. The top-fill design is also a huge plus—no more awkward refilling or spills. It’s quick, clean, and gets the job done. Cool Mist Magic: The cool mist is clutch for keeping things from overheating, especially when the lights are cranking. The ultrasonic mist is smooth and even, making sure every inch of my tent gets that sweet, sweet humidity. Hose it Down: The hose feature is just genius. It lets me direct the mist wherever it’s needed most, which is perfect for hitting those tricky spots or giving a little extra love to certain plants. It’s all about control, and this humidifier delivers. Quiet and Steady: It runs super quiet, too. No loud hum or buzz, just consistent, reliable performance. I can’t tell you how nice that is when you’re in the zone, focusing on your grow. Bottom line: If you’re serious about your cultivation, this is the humidifier you want in your setup. It’s reliable, efficient, and straight-up effective. My plants are thriving, and I’m pulling in better yields because of it. Highly recommend!

Spider farmer 6L humidifier is beautiful in its ' simplicity. Install the hoses, add water in the tank and plug it in. + easy to install + stretch hoses allow to distribute the mist in two directions + effective mist production + silent + big water tank - hoses accumulate condensation if curved - temperature display only in F° - dripping sound when low water level - the display turns off even when in use - really loose connection with the lid and primary hose All in all very happy with the product. Very effective humidifier. Keeps humidity level accurately. When installing make sure the condensated water does not drip on any electric devices! Primary hose could be longer.

I upgraded to this from a smaller humidifier, I will say this the mist output is amazing, i love that it shuts off on its own and the settings are easy to use, great value for the money, and you don't have to worry about checking it every few hours cause the capacity is amazing.

The humidifier shut off. I double checked to make sure there was a full tank of water and there was. So, I setup the humidifier once again. It ran for less than a minute and shut down again. The indicator for a empty tank was on. When this indictor comes on the humidifier shuts down because it thinks in is empty. However, the humidifier tank was FULL!!! This tank is 100% defective. I will be purchasing a different manufactures humidifier.

The media could not be loaded. Tropical Plant Parents!!! This humidifier is a must have for large plant rooms, small plant rooms, or if you are like me and have over 100 plants. Works well with so many extras, like misting. Only filled once in 10 days plus I have the humidifier set to 90%. The rarer monsteras love the humidifier and the cleaning is next to nothing. Oh don’t forget it is so quiet, I find myself looking to see if it is on. The only time I actually heard it was the beep when it was time to refill! A must have!
