    It does blow air in manual mode. The instructions I got said to adjust the humidity sensor calibration by holding two buttons to adjust it. That does not work. The humidity feature only partially works. On off on off etc. It does not run the fan long enough to actually change the humidity. The temperature feature does work but you cannot adjust the sensor to the correct temperature. So a few days later I’ve found a work around that makes this unit work much better. With a small piece of a cleaning sponge I cut a hole in it to put the sensor into then wrapped it in a kleenex tissue with a twist tie. This gives the sensor a buffer so the tower fan does not blow on the sensor. Spider Farmer needs to include something to buffer the sensor because all grow tents have a fan or multiple fans blowing on the girls. I upped to 5 stars because the Spider Farmer 6″ is doing what I need now.Read more

    The media could not be loaded. Wow just wow!!! Where to start…. Well if you are looking for one fan and smart controller to rule them all this is it! **Fan** The fan is clean and feels like it will last forever and the fittings are perfect snug. I haven’t used tape yet it fits that nice. (Haven’t set it past 2…10 is a lot of air haha) **smart controller** After reading the manual and using just wow. So you can program every level of what it will do. I run high tempature during the day and it will make sure the heat stays under control. I run high humidity at night and make sure I keep perfectly RH level.(you can even set a max speed for the fan) If you are new or know what you are doing this is the fan you want will grow with you and amazing control and customization.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

    This product does exactly what it promises. The temperature/humidity sensor is very sensitive and activates the fan the moment the temperature or humidity hits the settings you set. MY space was having high temps in the 100s I set the unit at 83 and the space has not gone above 83 for the 3+ weeks that I have been running it. The fan is solidly built and runs fairly quiet compared to other inline fans that I have used. My hats off to Spider Farmer for putting together a solid piece of equipment at a price point that is hard to beat I would absolutely recommend this Spider Farmer product to anyone who has been looking for an inline fan with programmable features look at the others this one is the best value for the money for sure Thanks again Spider Farmer.Read more

    I was an early investor in this fan. Finally a fan with a manual speed control. Unfortunately it was not as powerful or silent as the fan I was replacing. The seller reached out to me about my expectations, explaining they aren’t not trying to imitate other designs. We came to an arrangement as I still have use for this fan, only not the intended use. My suggestion get the 6″ model. I find the 4″ is actually much more powerful with some parts removed, that cone spacer piece, so the duct size itself is a limitation. The 4″ model is more like a 6″ fan limited by the duct reduction design. Get the 6″..Read more

    I have been using the 4 inch smart controller fan for extraction in a 2.3×2.3×61 grow tent. I really enjoy having it automated for when temperature or humidity gets too high. Was easy to install. It is reading very accurately, and has been preforming excellent. Would highly recommend for a quality, easy to use inline fan for environment control. I am doing a project on you tube with this item with weekly updates. Feel free to look me up,and monitor its performance. Mr Sour’s 420 growing adventures. Thank you, and is a 5 star product.Read more

    I’ve ordered two of these units and neither worked properly in automatic mode. The company is friendly to deal with, but you Should not buy this if you intend to use automatic mode. The problem appears to be in the controller. After a few cycles of triggering the fan due to high humidity or temperature, the fan then rubs continuously. The only way to stop it is to reset the controller. When the company fixes this problem, I would recommend the fan. For now, you may want to consider other brandsRead more

    Early days but I’m very pleased with the fan so far. I use it for fume and smoke extraction for a pair of laser engravers and it’s been running about 12 hours a day, every day, since I got it and it’s worked very well. Good air flow, relatively quiet and the fan speed control works as specified. No problems at all.Read more
