co2 controller worth it?

[PharmaCan]

I have a co2 generator, but haven't decied how to control it yet. As far as I know there are two ways. Have it shut off by PPM, or by time. The controler to use PPM is about $450. The cyclestat (for time) is about $150. I would much rather use PPM control.

Actually, you need both a timer and ppm contols. The timer so that the co2 only operates during lights on - the ppm to, obviously, regulate your ppm for optimal conditions. There are many controls available that do both time and ppm.
