I bought this item as an experiment to add a lightproof air intake on a 2x4 growtent. I've had it installed for about a week now and it's working perfectly. It's critical to have no light leaks during the flowering stage of my current grow and thanks to cooler guys I'm sure to have an awesome harvest this year.

The vent ducting I recieved for my diy project was exactly what I needed. I searched the internet specifically for this item and I found what I was looking for at Coolerguys. I also found another product I was searching for at this site. I highly recommend Coolerguys if your looking for quality products and fast shipping. Thanks Coolerguys!

Ducting crumples easily, so care required when installing. Item totally met my needs & compatibility with other CG items was key!

I got 2 120mm switch adjustable fans and ducting. I’m using it as an exhaust fan in my tear drop camper. The installation is not complete yet. But It’s all coming together nicely and works well. I’m confident I will get adequate airflow in the hot summer nights to sleep comfortably.

Great products and service
