Love this humidifier!
Bought this for my grow tent and it’s been great. Strong mist output, easy to aim with the hose, and the GGS controller makes it super easy to keep humidity where I want it. The 5L tank lasts a while but I do have to fill it up every morning. Quiet, simple, and reliable. No leaks, and it’s small enough to have in the corner of my 3×3 tent along with 2 5gal pots with plenty of of room still. Definitely worth it!

Very efficient and maintenance free
I bought this to replace a little 4 liter humidifier I had in my tent that I had to refill every other day. This 5 liter humidifier has a sensor that hangs in along the vegetation giving more accurate readings for the humidity in my plants setting my environment up for optimal transpiration, and hose that can be adjusted for better delivery. I filled this humidifier two weeks ago and its held my level around 50-60% for weeks. Im super impressed at the efficiency of the super important and affordable piece of tech. Im dropping the levels of humidity down to 40% now and im confident I won’t have to fill it all the way to the end of flower. Im in a 4×4 tent, btw. I love this humidifier, and I have a T7 to compare it to. Best bang for the buck.

Awesome Customer Support, awesome products!
Great products all around. Some of the best grow lights I’ve used. Love the GGS controller. Everything was a breeze to connect, and I love being able to control all functions from my phone. On the one occasion I did have an issue with a faulty humidifier, customer service was on it. I will be a loyal customer for as long as your company is around. Thanks again, Spider Farmer!

$90 fir less than 2 months service!
Purchased October, window closed November 11and here we hit December 1 and the crazy thing isn’t working. It was great though small. I had a 6 liter before, but this was working great for my orchid grow tent. And then the last week it won’t hold the humidity— not too little… it’s way too much. Have it set at 70%, all of a sudden I notice one morning it’s not running, it’s out of water. I filled it the night before. I thought well maybe I didn’t. It has an auto cutoff if it runs out of water. So I refill, was a little ticked with myself because the humidity was down to 38%. But just said to myself, don’t do that again. So then the next few days it was the same ie out of water by anm, and then the third day, I opened the tent and it was like a cloud forest in there. I have stand alone humidity meters to double check the device for sensor accuracy throughout the tent. I immediately turned the device off and they both (auxiliary meters) read 94 and 96%., moisture on the leaves, floor. I don’t open the tent every day because it’s winter and the heat is on so don’t want it to escape, but have both circulating fans going and an inline ventilation fan/filter going to keep air as fresh as possible so no fungal issues. This is not new for me, have been running a tent for the past 3 winters with this being the fourth winter. Plants are outside in summer. At 70 have been growing for over 5 decades. My orchids are expensive and I want them to stay healthy.So disappointing— it’s suppose to have a 1 year warranty which has always been plenty. But then to discover Amazon isn’t going to cover $90 for less than 2 months of use. I’m going to try and do a phone call with them — but they don’t make it easy at all to reach customer service. And getting Spider Farmer to reply is next to nil. When the 6 liter went bad, I wanted to see what about getting repair parts, or the bottom chamber, or to even see what the new products were… couldn’t find a replacement 6xx called them 3 times, left email US distributor and not one answer. So that’s why I ordered the 4 liter. Very disappointing I would gladly go to a larger type humidifier but the tent is not big enough for a $400-500 and up per the manufacture of those types. And they need a dedicated water line hookup. So now I’m stuck. Don’t know if this is a fluke or what. But have to do something as it’s winter and orchids cattleyas, Vanda etc don’t like dry indoor 25% humidity. They want 70-75%, minimum is 55-60%. I was okay with getting 3 years out of the 6 liter, and it was like $20 cheaper too, well not okay, considering only used in the winter and had to pay more, but I didn’t think twice about getting another one except I wanted another 6 not a 4. But as I said from Oct -now, it worked great so I thought it was just more efficient and maybe they felt they didn’t need to go with the larger unit anymore. Well that was a big Rutrow! Tried yesterday to back it down, both on mist level and percentage, but it’s just not reading right — either too low or too high.… sensor issue, or the machine is just zoning out on setting. Not sure — just not working properly. I clean it each week like they say, just don’t know what to do. I will say originally I had with the 6 the unit in the tent but they didn’t work well at all..once I put the device tank and all outside the tent with just the sensor inside — never had another issue until when I started it up Oct.1. Did the same with this 4 liter and like I say was great— until Dec 1. So I got 2 weeks beyond the 30 day return.Received October 11, return expired Nov 11 — stopped working correctly Dec 1.

Getting this is the right position is no easy task, I’ve been using it a little over a week and have used a roll and half of kitchen roll on the hose leaks. Hopefully I find the exact sweet spot to stop that happening before I go away.

Topproduct !Enige nadeel is dat het wel vermeldt mag worden dat er voor bluetooth-verbinding , een ‘spiderfarmer controllers nodig is. Deze kan natuurlijk bijgekocht worden.

Bin sehr positiv überrascht, hier lohnt sich die Investition definitiv. Der Grow-C3PO hat ein schlichtes, modernes Design und eine selbsterklärende Bedienung. Demnach geht der Aufbau schnell und unkompliziert von der Hand. Der Schlauch könnte zwar etwas länger sein, erfüllt aber bei korrekter Installation seinen Zweck.Sehr Praktisch ist für mich die Kompatibilität mit dem GGS Controller und der Spider Farmer Steckdosenleiste. Ich nutze das Gerät sowohl in der Vegi-Phase als auch am Ende der Blüte, perfekt für Teilernte oder wenn es im Zelt trockener wird.Der erzeugte Nebel ist satt und dicht. Über das Touch-Display lässt sich nicht nur die Nebelmenge, sondern auch ein Timer und die gewünschte Luftfeuchtigkeit einstellen, denke das ist optimal, falls man das Gerät nicht in Kombination mit Controller oder Steckdosenleiste nutzt.Insgesamt ein durchdachter und zuverlässiger Luftbefeuchter, der meine Erwartungen voll erfüllt. Deshalb hab ich ihn auch C3PO getauft.

Producto perfecto para armarios de cultivo con poco espacio, funciona genial, no se como no hay mas productos como este, y la marca spider farmer no la conocia y estuve viendo un poco y merece la pena echarle un ojo a sus productos, por el momento con el humidificador estoy muy contento.
