Spider FarmerAir Filtration Kit 4 Inch, Inline Duct Fan with RJ12 Speed Humidity Controller, Carbon Filter Combo, 25 Ft Ducting, Ventilation System Kit for Grow Tents, Hydroponics, Indoor Gardening

The fan is awesome with the new controller

Easy to set up for beginners even. I have mine both on the outside of the tent to allow for more room for the plants and light. Top notch system! My humidity and temp are perfect. Grab one of these on a sale it’s well worth it

Easy setting up, but wish they gave better instructions on how to put together. I had to figure some of it out myself.

Just got all of my Spider Farmer Indoor grow components, everything is in perfect condition, I just need to get the Dehumidifier component, and upgrade my light soon, SPIDER FARMER I will definitely be a product reviewer send me some goodies, 4x4 tent !! Haha good stuff so far!!

I liked how much air this fan moves and how relatively quiet it is for its size. I got the 6 inch size fan to exhaust hot air out of my grow room and it works pretty good. My room has gown down 10 degrees since installing the fan. It took a little while to dial it in with the timer but definitely got the job done once set up properly. Also included was hygrometer/thermometer and 5 fabric pots that were a nice surprise.

This is a well constructed inline fan. It works great in my Spider Farmer grow tent. It should last for many grows to come. Highly recommend.

I also got the spider farmer sf 4000 and have it in a 3×3 tent and wow my 1st and 2nd time growing turned out sooo goodIt's as good as anything from the medical marijuana store

Much noisier than expected. In fact it’s noisier than another model with a higher decibel rating. The plastic housing seems to vibrate loudly and it howls at lower speed. Pick your poison.UPDATE: I've been using this for a month and the fan has now developed a loud knocking sound. I believe the fan is unbalanced and "knocks" every few rotations.
