Horticat U80 Pro

Works beautifully and trouble free

I am a plant entheusiast and our collection is quite extensive and very sensitive to humidity changes. We typically keep tropical plants that require 70+% Relative humidity and some will get super crunchy sad leaves if the humidity drops below that for any extended period. We live in the desert and keeping humidity that high and stable can be a challenge. Previously I had stand alone units that were 5 or 6 gallon and rated for 2000sq feet. They worked fine but my humidity was always +/- about 10% in either direction. They also required constant water filling as fornour greenhouse size they would go through 5 gallons a day easily. In the last 3 years I have gone through 3 of those stand alone units and this time I decided i was done with them and needed something real. Honestly this unit isn't much more expensive than a good stand alone unit and it is INFINITELY better. First off: wall mount is a God send. Frees up so much floor space and makes the room seem so much less cluttered. The auto fill is fantastic as now I can just let it run instead of worrying about it when my spouse and I go camping for 3 days. Now I just set the humidity and it just does it with zero effort on my part. And the humidity is dead set stable. Our greenhouse has a good amount of air circulation and we have 3 independent humidity monitors around the area. All of them read within about 3% of each other which I attribute to device precision. They never read exactly the same even when placed in a small plastic bag together. So far the humidity has stayed exactly where I want it and within the 2% deviation toleration we set on the machine. Set up took me only about 20 minutes which is probably faster than most but I have previous plumbing experience and my layout was pretty easy to run cords and water lines. The package came with absolutely everything I needed except for a single T joint to tie into my RO/DI system. It came with about 35 feet of water line and about 50 feet of drain line. Set up was easy and pretty self explanatory even though the instructions aren't the best. I think anyone can do it with a little thought and problem solving. My only possible complaint is that the unit is slightly noisier than I expected. I tested and with my fans running the ambient room noise averages 43 decibels. With this humidifier running that sound goes up to anywhere between 51-54 decibels. It's not loud but it's also notable. In my situation that's fine since it's a greenhouse but I also have a reading nook in there and maybe it will bug me while I read. I think I can easily make some improvements though with a little sound dampening insulation around the ultrasonic basin and swapping out the internal fan (which is what creates most of the noise) for a similar size and voltage ultra quiet aftermarket fan. Would probably cost me all of $15 to buy parts and half an hour to make it completely unnoticeable over the ambient noise. I can't comment on longevity as I've only owned it a few days but it's a simple machine and looks well built so I anticipate it will last a while. As of right now I could not be happier with this unit.

We bought this system about 4 months ago and we are VERY happy with what it does. We have several expensive large format plotter printers that are sensitive to humidity, it must be between 60 and 70% humidity for them to function correctly. This does that with ease. Our print room is 150 sq feet and has constant traffic in and out all day and it does maintain the set humidity without a problem. Given that this unit is a fogger, make sure you mount it where it is not blowing directly on a printer. It is a very simple install, hang it, plumb it, plug it in and set it and forget it! That is it, 20 mins total install time. The controls are very simple to program. It does come with all of the proper fittings. All we needed to buy was a 1/4 inch T tube quick connect fitting to splice into our RO system.

At first lot of fog comes out after couple months barley nothing, even cleaned really good and still nothing, for the price could have been longer lasting highly disappointed cause wanted for long time and was a big dent in wallet

This is a very powerful and solid unit. It worked well out of the box for over a year, then it had some issues, but Horticat customer service is amazing and solved my problems. I believe a well maintained RO water filter is a necessity for this unit, because the dissolved solids in water will cause a white dust to settle on everything. This is the nature of any ultrasonic humidifier.

I installed this device in a 1500 square foot ranch home owned by my 97 year old Mom who cant breath in dry air. It has run in winter months constantly for five years having purchased it in 2019, I noticed a lower output and then the water feed stopped working, I had cleaned it out a couple years ago which was quite easy really to disasemble and wash the parts etc the water tank and the ultrasonic unit can be removed from the tank etc. anyway the unit stopped working but I noticed the sensor was still operational and these are expensive so I wrote an email to support that evening. I had an answer at 8:30AM the next day. Long story short the ultrasonic sealed unit was played out as well as the water inlet solenoid which I may have been able to clean. I ordered a new ultrasonic unit and the new inlet solenoid both which are easy to install and the parts are on the way for a fraction of the cost of a new one. The parts were confirmed the issue with the techs. The unit that I have has an older style Power supply which has been updated to seal out moisture but with this level of service I would order another with the newer style if this fails in the future which it has not thus far. All well spoken knowledgable american english humans for those of you that find that as important as I do.

This works seamless for me. Keeps my exact settings that I put in. It was very easy to set. I needed a great deal of assistance as I needed an additional part with my setup. They set me a part right away. Once I got it. Any question I had was answered. He even gave me his personal cell phone so he could walk me through the steps after hours. I would use this company and product again without question

First unit was DOA. Got a prompt phone call, and without hesitation the seller sent over a new unit. New one arrived perfectly and works awesome. Things go wrong sometimes, and having a seller who stands behind their product says a lot, I’m thankful for the support! The application was bringing the room up to a proper humidity level for a UV printer in a 1000sqft long and narrow space. The humidity sensor is spot on and kept it at the rated humidity level with no issues at all. The fact that it hooks to a direct water source is also fantastic. 100% would buy again!

The device continuously overfills with water, requiring me to manually drain it multiple times a day for it to operate. I've connected the RO outlet directly to the humidifier, but it doesn't automatically shut off when the water reaches the optimal level. Instead, it keeps allowing the water to overfill and then drain. Once the tank is full, the humidifier stops working until I manually adjust the water level to its optimal point. Practically Useless!
