A Clarification
for
Irrigation Vaiants
Water application amounts and run times will vary according to several factors
The Soil or Grow Media
The plant "water use type".
Whether there is a "Pre-Set Runtime
If "Less than Optimum" moisture depth is selected


There are three different water quantities specified:

1st - The amount that will be supplied if the emitter count and run time specified are followed
This is a calculation based on emitters multiplied by time, and varies from optimum as a fraction of an emitter is not possible, and rounding off must occur.

2nd - The amount that is technically required for optimum outcomes.
3rd - The amount needed if watering a completely dry soil

With proper irrigation, water is reapplied before plants wilt.
So, there will already be some moisture in the soil when a new irrigation begins.


Drought tolerant plants should have dryer soil than Heavy water use plants when it is time to reapply moisture. Therefore; though requiring irrigation less often, will need a bit more water when irrigated.

Due to these factors, the calculator specifies the different quantities of water. If watering a new plant with dry soil, then use the quantity of water specified for that, or run an extra manual start for the regular optimum run time.



HOW MANY GALLONS SHOULD YOU PROVIDE TO
YOUR POTTED PLANTS?
(how many minutes / gallons)
Remember "how many minutes" varies with the number and flow rate of the emitters you use.
Most emitters are rated in gallons or fractions of a gallon per hour

As shown here; 1/4 inch dripperline has "built-in" 0.75 gallon per hour emitters.
These are evenly spaced every 6 or 12 inches depending on which style used.
By cutting a specified length then adding a plug at the far end, you will get the correct number of emitters needed for the pot being watered.
