How Many Plants per Pump System?

The basic maximum water supply with our pump systems is based on the on/off cycle: they should to be off 2x longer than they're on. So if on for 10 seconds, should be off for at least 20 seconds before turning on again. They will still work fine if less than that be it can shorten their life quite a bit.

Digital Blumats

Make sure to only soak the base, not the top with the digital read out! If you do the standard Blumat setting of turning the top down until just one drop clings to the 3mm tubing and then turn the top knop down 2 of the triangle markings, that in general corresponds to a 120 mb reading on this meter.

All growers have done it: damaged a plant with erratic watering practices. But for cannabis cultivators, the compromised health of just one or two prized plants can significantly impact the bottom line.
