Example 1
One perimeter pipe & one staging sprayer
Seedlings, small pots and trays need more regular watering than plants in deep soil. Run zone 1
as a perimeter pipe around the greenhouse with drippers or sprayers for a once-a-day (or less)
soaking of the larger plants, and have zone 2 spraying or misting your seed trays and pots on the
greenhouse staging / shelves on a more regular basis, perhaps controlled by a soil moisture
sensor.
Example 2
Two perimeter pipes
Having two perimeter pipes lets you use water from either irrigation zone anywhere in the
greenhouse.
Example 3
One perimeter & one ground level
Use zone 1 with a perimeter pipe to provide water for general sprayers and drippers around the
greenhouse, where the plants need it. Use zone 2 with a ground level soaker hose for watering
efficiently in rows without wasting water.
