btw abs, question:
when you use that super blue bulb what kind of ballast you need with it?
oh and also i use to own a hydrofarm co2 regulator also and i might have the same problem as yours. The solinoid doesn't shut off when no power is going to it. I fix this but opening up the solinoid and greasing it with some wd40 where the metal piston goes up and down and that fix my problem.
