Spider Farmer 4 Inch Inline Duct Fan with RJ12 Speed Controller 205 CFM Quiet EC Motor Ventilation Exhaust

Excellent blower fan to handle 3x3 and 2x2 tents with ease. GGS controller and smart phone app utilization makes control a breeze. There are a lot of power level settings through the smart phone app, as well as timer cycles, humidity/temperature cycles, etc. Options galore! I’ve been running my first fan for several runs and performance is A+. Thanks, Spider Farmer! Read more

We have been using this fan to exhaust our grow tent and it is powerful… it arrived well packaged in a box with the sensor unit and monitoring screen in a separate box within the package. It came with instructions and recommended variations as to how one could set it up in a grow tent as there are several possibilities though with the easy setup one could get the job done. We wanted this particular fan because of the smart features and control it allowed us to have to boost our grow to the next level. We feel like this is a next level fan in general as it has had the power to exhaust even larger grow tents than other fans/tents we have used. Back to the fan lol… the reason why we are a fan of this fan is it has literally allowed us more time to work on the plants without having to worry as much about the environment as it has ten different speeds which automatically change to adjust the environment of our grow room, and to our specifications maintaining a healthy environment with on point humidity/temperature levels. We placed the sensor in with the ladies (plants) and tested it with our hygrometer, seeing it was on point and the way it was delicately packed with a thick clear plastic protective film over the sensor, was overall satisfied with that aspect and in general. We connected it to ducting and a carbon filter as it has the power to scrub the air clean through our exhaust system, and am pleased to say it is extremely quiet for a such a powerful fan… compared to other exhaust fans was worth it because we have had more time to do other things in the garden which require more attention as it allowed us to have a hands free monitoring system for not a bad price. It has pulled its weight in value as you can see ;) Read more

Very power fan does the job most of the time on 25 to 30% the controller works but you still have to monitor it. The excitement of opening it kinda fell off when this was the 2nd purchase of spiderfarmer product that I made and no cool stickers but whatever 4 stars for product you lost one for the stickers Read more

works great. does exactly what I needed it to do - cools a previously hot second floor room Read more

Works as intended easily connecting other accessories and app control Read more

GGS controller didn’t come with power cord. No response from anyone about it. Even emailed spider farmer. I also didn’t get the metal bracket to mount it on the tent. Contacted spider farmer and they have been just giving me the run around. Don’t buy from them. If they won’t even cover the tiny stuff imagine if you had a real concern with a large expressive item. DO NOT BUY From this company Read more

Definitely worth the money ! Read more
