I purchased a 4 inch inline duct fan and 4 inch ducting. There was a doggie door in my garage wall when I purchased the house. So I just put a piece of plywood with some board insulation glued to one side in the opening and cut a hole in it large enough for a 1 way exhaust vent. hooked everything together and added a 3d printed ring with embedded magnets to the end of the hose that goes up against the printers back fan.

I found instructions that were way too basic, and links to $700 setups but nothing in the middle. I’m thinking about eventually making a write up or video on how to do it, but the upshot is to buy a 4” duct fan on Amazon (link below), attach it to a 4” PVC, drill as many holes as you need in the PVC, and use fittings to attach vinyl tubing to it. \r\n\r\nI think I have $75 into this setup for 5 pairs of boots. \r\n\r\nVIVOSUN 4 Inch 195 CFM Inline Duct Ventilation Fan Vent Blower for Grow Tent https://www.amazon.com/dp/B01M7S46YZ/ref=cm_sw_r_cp_api_glt_fabc_D92HS8RBQW8Q63XHZXT6?_encoding=UTF8\u0026amp;psc=1","subreddit_name":"skiing","author":"1-900-FATCHIX"},{"body":"VIVOSUN 4 Inch 195 CFM Inline Duct Ventilation Fan Vent Blower for Grow Tent https://www.amazon.com/dp/B01M7S46YZ/ref=cm_sw_r_cp_api_glt_fabc_3PCEHNXM0Y1RPR9HAV9C?_encoding=UTF8\u0026amp;psc=1\r\n\r\nThis is the fan I got and overall it works great and the sound is really quiet.

And as it blows every couple 20 seconds or so it will sputter a little bit with water and make a noise which is annoying. But the fan it self is really quiet.

Do you have a humidity controller set to regulate the RH range? And a thermostat that controls heat?  You need an exhaust in order to get the air flow moving so it always is pulling air out at about the same rate fresh air is going in.  If the answer to those are all yes then you got all the elements necessary to grow Martha Tek. If not make the adjustments so they are. \r\nYou probably can get away with this exhaust if you have a small tent inside a room. But you may need a dehumidifier in the outside if the tent so you don’t damage your room. \r\n\r\n[Exhaust Fan](https://www.amazon.com/dp/B01M7S46YZ/ref=cm_sw_r_cp_api_glt_fabc_F3HZN0NPJ3M4EYXCRAK0)","subreddit_name":"ContamFam","author":"DayTripperonone"},{"body":"Thanks for your reply!
