Autogrow EC Mini-Doser System Complete w/2x Peristaltic Pumps

A single function controller that lets you control your EC.

The EC Mini may be used as a mains powered monitor or, by adding two solenoid valves or pumps, it becomes a fully functional dosing system, managing fluctuations in your EC. EC fluctuations in your reservoir are not only time consuming to correct, but can have negative effects on your crop performance. This simple EC Mini will monitor your EC levels and add EC adjuster to maintain your desired set-points. Adding peristaltic pumps will allow you to keep your EC adjuster in larger containers on the floor, avoiding issues associated with gravity-fed valves.

The EC Mini is from a family of monitors and dosers that have been proven over many years. This latest monitor/controller has built upon this pedigree of simplicity and innovative features.

Fail-safe dosing may be inhibited if any of the following is detected:

• EC sensor module failure
• Dose count per hour exceeded (DC/h)

Checking dose count is useful if a leak should develop or the pump fail and should prevent continuous dosing alarms. The alarms can be enabled to operate on the controller when the EC or DC/h deviates outside the user set-point.

The EC Mini is affordable enough to be used as a mains powered monitor, continuously displaying the measured electrical conductivity. By adding solenoid valves or dosing pumps it becomes a low cost dosing system.

Note: Tubing for the peristaltic dosing pumps is sold separately. Bluelab recommends using their tubing but we have also had luck using our clear 3/16" ID x 1/4" OD tubing. It's extremely flexible which comes in handy when the path from the pump to the stock tank isn't a straight shot. If your clear tubing arrives kinked simply dunk it in boiling water for about a minute and lay it flat or hang it for just a bit.
