Trying to fit cool tube reflector in grow room. How to make 6inch to 4inch duct adapt

[brainzfuxed]

Hey all really need your creativity. My grow tent is 3 feet wide, 2 feet deep, 5 feet high and my cool tube reflector is 24 inches wide. The 6 to 4inch adapters I got at Home Depot are too wide at 8 inches each. So having to put an adapter on both sides of the cool tube plus the length of the cool tube is too big for my 36 inch area that I have. Does anyone have ideas on how I can create a mini 6inch to 4inch adapter or make this fit in my tent? Or does anyone know a smaller cool tube? The one I have seems to be the smallest possible.


Appreciate all of your help guys

I've seen someone wrap insulation/padding around the 4" metal vent hose, put the enlarged end into the cooltube & use metal tape to bind the two. Careful planning makes a very tight connection and reduces distance needed a fair bit.

That's a 6" cap & a 4" starting collar (maybe 5" in the pic) from Lowes or Home Despot. I'd seal the joint w/ caulk.

I like this style of snips-

Cut the hole counter clockwise. They also make right cut snips.

chances are you have multiple tapered plant pots sitting about?
I have used them several times in a pinch as the base of a reducer.

Plastic and only a few inches wide, slides right over the cool tube and 4" flex duct hooks up to the other side.

It's made by Broan, same dudes that make the bathroom exhaust fans.
eBay, Home Depot, electrical supply house. A couple dollars

Even easier once you have 'em. That's a broan 475b. Neither Lowes nor home depot list them. widely available online.
