Indoor Air Cooled Ducting

Hi,
Hopefully someone can give me some advice/help. I'm trying to air cool my 400watt hid light for my 4x4 tent... I have duct booster fan and I guess now I just need to pieces of ducting to attach to the hood... Would this ducting work?

Wrong kind,If you have a grow store near you they carry the right duckting.If not goggle hydroponic supplys and you will find them.

I've found that type is hard to work with. The flexible type used for dryer vents is cheaper and easier to use IMO.

I agree with Muddy, it likes to keep it's shape so moving lights will be a chore, and it will be harder to cut to length. Also after you cut it, it will be sharp too. Namvet suggested hydro stores, sure-fire spot for it. Also look at your hometown hardware stores too if you are too far away from a chain home improvement store. I can't tell you how often I have to remind my wife that there is a superb Gil-Roy's hardware with VERY knowledgeable staff less than a half mile from our home!

Anyways, I hope you are able to get that cooling taken care of
