Really nice stuff here

EDIT 5/7/15 Okay, first of all this CO2 injection system works exactly as advertised. I have a 10x10x8 grow room and didn't buy a CO2 meter so after sealing the room with silicone I set the flow rate to 2 hrs. meters of CO2, it accumulates quickly. I reset it to 0.5 hrs. Cube feet per hour and now at 5pm my CO2 is around 1500ppm easy to set up and adjust but you need a digital CO2 meter. BLACKED. I've been using them for a few months and thought I'd give an update. First, I like the rubber washer which eliminates the need for one of those stupid compression washers that all other regulators require. 2 lock nuts broken. It's the nut that attaches it to the CO2 tank. What happens is the mother's back panel breaks off, for some reason it's not a solid piece, it's actually glued on. I insert an image. The round circle you see next to the nut must be part of the nut itself. You need to replace this nut, but you also need to replace the stem that the nut fits on, it's not the normal size, in fact it's a lot smaller than the original. These parts are cheap now, but in the end it should have been built that way. With. In the 2nd photo you can now see the damage done to the stem where you put the rubber seal when it exploded on the tank. I have 3 of these but I can't recommend them more. Do yourself a favor, dig deeper and buy a decent one.
