How do i make my 400w HPS air cooled

Glass should be available in a couple of thicknesses at Ye Olde Giante Hardwarre Shoppe. Your local glass shop may have some good suggestions for you. Glass used for picture framing is usually pretty thin and colour neutral.

Nice cooltube pics, that should clear up any questions on what they are, how they work or how to hook them up. That should help out a lot of people. ++++REP for you !!!!

yeah like he needs any more of that haha. only problem with the hardware shop by me is that they wont cut the glass down to size so i might as well see what they have at the grow shop first.

No glass shop or picture framers around?

Cutting glass is a piece o' piss, BTW. Glass cutters are cheap as chips, just scribe a line with the cut wheel (in one direction, one pass only), put the scribed line over the edge of a table or workbench and it will snap cleanly. Clean up any rough edges with emery cloth or sandpaper.

nope none that i know of. i went down to the grow shop and got the one that was supposedly for the reflector i have. well guess what it didnt fit guess i should have measured also before i left! well back i go...
