Going into business for myself - Who needs a cool tube?
Hehe, just kidding. Sprayed my plants today with Azamax and decided to be productive while I waited for them to dry with the main light out. Switched to my HPS and modified my DIY cool tube so that I could strap my carbon filter to the other side. In the future I can also veg with the bottom half exposed and draw from the top which should help.
I strapped a piece of 6" ducting to the top, cut a notch for the cord, added a tiny reflector I had sitting around for shits and giggles and then strung it up.
My next project is a kiefer for my trim. If it works on a tiny scale I'll beef it up.
