Al - They're Hydrogrow (commercial) tubes. I was going to build the tubes myself using 6" bake-a-rounds. I went to E'bay and found two bake-a-rounds and tried to order them. For some unknown reason, PayPal wouldn't process updating the expiration on my c/c and I wrote the vendors to make other payment arrangements and they never wrote back to me and I finally just said "fuck it!" and bought the commercial units.

IF you could get the 6" bake-a-rounds, the tubes would be simple enough to make. If you just wanted a single light (not two or more hooked in series), you could use just about any Lowe's lamp glass. But my cool tubes only cost US$80, so you might save $30 - $40 each by making them yourself.

And really - the cool tubes don't have to be all that well made. There is more air flow and more air turbulance in your vacuum cleaner hose than in the cool tubes. I have a 470cfm fan. With all the twists and turns and filter, it's probably moving 350cfm - 400cfm. The air flow thru the tubes is maybe like a hair dryer on medium setting. The point I'm trying to make is you don't really need to get all that gung-ho worrying about sealing the tubes. There's very little air pressure involved, so simple taping would suffice. And the tubes never get much more than warm, so duct tape or foil tape will work well and last a long time.

my keyboard batteries are very low - sorry if there's a bunch of typos in this.

As a professional builder who is skilled in most of the trades, building this cabinet was pretty straightforward ā?? a lot of work but nothing very complicated. This might be a little advanced for someone with no construction skills.
