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

Pros:price point for kitThe ability to control extraction for humidity and or temperatureCons:No straps to hold carbon filterCFM of fan is extremely lessened by the carbon filterNeed to disassemble fan in order mount to the wall or anything for that matterI like the ability to electronically control fan speed and have it linked to temp and humidity. The noise the fan makes is loud enough to hear but quiet enough that it's not annoying. I wish it had straps for the filter and the way the fan mounts to the wall is difficult. It comes with mounting hardware which is a plus. All in all, id purchase another one, but id probably go with the 6" as it moves more air.

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!!

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've been growing for over about two years now and decided to give Spider Farmers ventilation a shot. I have to say I am VERY impressed! Came with everything I needed to install in the box, and it all fit like a glove. The carbon filter did a wonderful job of not making the neighbors smell what I am growing inside the grow room. I've tried many other ventilation brands, but have to say this is by far my favorite one! It's not too loud, and it moves air very well. Shipping was very fast and I received it in a timely matter. 10/10 Would buy again!

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

Like everything else they sell, comes in broken, and SpiderFarmer dies not respond to any messages or emailsz so even if you do get something that works from them, and it goes bad, there is no way to contact them. The controller is cheap too, no app ir smart controller, you have to go git buttons to change anything like its 1970. Stay Away from spider farmer
