The watering system should be set up on its own timer separate from your other landscaping. The initial settings are 6 am, 12 pm, 2 pm, and 4 pm, and one minute of watering at each setting. As the season gets warmer, stick your finger in the sand a few minutes before watering time; it should be dry on top but moist down at the ¼ inch level. If it’s not moist, then you need to increase your watering time by one minute. If there is water leaking out of the holes of the bag after watering, you can decrease the cycle time by a minute. Fortunately, while you might end up wasting a little water, you can’t over water the garden because the excess escapes through the holes in the bag.
{Rain will not harm your garden, as mentioned above over watering cannot occur because excess water escapes through the holes in the bag}
