Ducting?

Where do you guys buy ducting for your cool tubes? I've tryed lowes and homedepot. I need two 6"x25' lenghts of ducting.

Try other Local Hardware stores that sell heating and cooling supplies, Try a heating and cooling company. Get a 6" to 4" collar and then get the 4 inch flexible duct at Lowes or Home Depot. I know they have the 4 inch. flexible duct., also I see some of the Hydro shops online carrying it.

I was at homedepot and bought ducting. They have all kinds of sizes. I know they have it. 6" insulated 25' lengths are 26 bux. I also bought un imsulated 6" there before.

You may want to look into insulated ducting as the regular stuff seems to get pinholes that smelly air can get sucked into.
