time.
The recommended number of units
is based on average needs of medium water use plant

Irrigation supplement is designed to significantly increase
the time between watering cycles for container plants.
The frequency at which you apply water will depend on
the climate and the plant materials.
Plants in above-ground containers dry out faster than
those planted in the ground. When RBIS is used in this
manner, additional watering will be needed.
Users are advised to observe plants for any signs of
stress, then water immediately to avoid damage to the plant.
