How do I use my Grow Flow control bucket timer?
Each segment (or tab) around the clock face represents 15 minutes. A segment pulled away from the center of the clock is on Drain, and pushed toward the center is on Fill. Set all on Drain, then set one or two segments to Fill every few hours when you want it to water. Set the correct time of day by grasping the outer edge of the clock face and manually rotating it (clockwise only). There is an arrow in the upper-right corner. This should be pointing to the current time of day. The clock hand in the center of the timer is the minute hand, and will make one full rotation per hour.
Why is the "Switch Error" light on when I plug in the controller bucket?
First drain water from bucket. Make sure the uppermost black float switch (the overflow safety switch) is installed correctly. It should be straight, not bent, when at rest (no water in bucket). See diagram under the Files tab for details. Once installed correctly, unplug unit to reset the error.
How often should I change the hydroponic nutrient solution in my reservoir?
To ensure optimal nutrient availability and freshness, change reservoir solutions completely every 1 to 2 weeks. If needed, top off low reservoir levels with 1/4 strength nutrient solution or plain water.
