CO2 systems. Pressure, hoses?

Hello.
I would like to install a CO2 system, fully automatic.
When I get a CO2 tank, what pressure should I run after the pressure regulator into controller? And do those controlers have simple hose input, so I can attach a hose and screw it with a clamp?

ask the people who make the system

Most CO2 controllers are little more than a switch, powering on or off the electronic tank regulator depending on a metered reading of CO2 concentration. It is the regulator that has a hose to deliver CO2, which is fitted straight into the unit.

AFAIK the tank pressure setting has little effect: the controller will continue to run the regulator until desired saturation level is reached. For preset controllers this will be 1,500ppm.

I've trialled with various DIY delivery systems in sealed rooms, piping the gas directly to plants, but I can't claim any benefit over fitting the hose to a fan or AC vent.

titan makes a really cheap controller and basic "HALO" style tube system.

the regulator controls the pressure. at least mine does. I just have to make sure the valve is open.
