I have never seen this happen until now. My room temps have been incredibly high recently and I thought it was just because of the weather but after a couple weeks I finally checked my ducting and saw that the inside plastic liner had pulled off, ballooning out and clogging the 6 inch ducting.


I replaced it with semi- Ridgid duct which doesn't have the liner. Now I can run all 1600 watts and the temps are great!

If you’re not filtering it before you exhaust that’ll happen. Also need to make sure you filter the intake so not to bring all that dust and debri into the room or tent. All ducts collect dust and shit in them good catch though.

That's odd. I've been using the cheap ducting like that for years and have never had that happen. I've also never seen it occur in other applications requiring ducting.

Looks like a manufacturing defect. How taut did you have it stretched?

It wasn't pulled very tight. It was nearly fully extended but supported by bungees.

Never seen that happen. I wonder if it was made in China.
