Automatic Plant Watering Device (simple version)

Step 6 Set the timers.

Set up both of the vacation timers.

Follow the instructions that came with your timer. With mine I had to insert a backup battery and set the clock.

Tip: The battery backup on the timers is a good feature if there's a chance of blackouts or brownouts.

Plug each pump into a different vacation timer.

We use two timers because it's important that the pumps run at different times.

Set the timers to turn on on for exactly one minute each, but not at the same time.

For mine the bottom one comes on for one minute from 10:00-10:01 am every day. The top pump from 11:00-11:01 every day. It doesn't matter as long as they don't pump at the same time.

If you don't want it watering every day make sure you can get a timer that will let you set up a weekly schedule.
