Super fast,delivery , super simple to assemble and they are the best in the biz quality of a quantity any day with key components.

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!!

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

The fan is awesome with the new controller

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

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

Happy with the purchase but after three months of use the plastic inline fan sounds like its started to fail. I think one of the fins is loose? Unsure but makes odd sound.The inline charcoal filter DID fail! Not scrubbing at all. Reached out to Spider Farmer and haven't received an answer yet. Review will be updated once they resolve these issues.

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.
