Duck Mount Final

This the complete duck mount system for your 4" exhaust fan hose that rest on top of your grow tent. It uses the Sharkbite plumbing PVC to connect the parts and can be cut to the desired length. My unit is 12" and holds a fan controller switch and temp monitor from Active
Air. The Duck ballast is full of duck balls (ball bearings) to keep it from tipping over. Fishing weight would also work.
