Re: [APD] CO2 use - off at night? -- or - plugging timers
Hmmmm. With a controller you maintain a CO2 level all night
that you don't really need since the plants aren't using
it. You could let the pH drop a bit at night. If your'e
going to al the expense of a pH contorller and solenoid,
why not hook up to the light timer also and save that last
little bit of CO2?
