Container Watering Volume Calculator

Container Watering Volume assumption to check

Drainage, substrate, roots, and pot shape affect the useful dose. Need emitter-equivalent requirement? Open Drip Emitters per Plant Calculator.

Arithmetic used for Container Watering Volume

Container Watering Volume multiplies factors from Container volume and Watering fraction to produce water per irrigation.

Container volume at 5 gal, watering fraction at 0.18 produces 0.90 gal in the demonstration case.

What the water per irrigation output means

Use Water per irrigation to estimate a container watering dose as a fraction of container volume. Keep the Container Watering Volume inputs beside the output. For water per event, use Tree Canopy Watering Calculator.

Drainage, substrate, roots, and pot shape affect the useful dose. Check container volume before applying water per irrigation.

Measurements for Container Watering Volume

Water per irrigation is calculated from Container volume and Watering fraction. Check the Container Watering Volume units before editing.

Container volume

Default in Container Watering Volume: 5 gal.

Watering fraction

Default in Container Watering Volume: 0.18.

How input changes affect water per irrigation

Run another case with Container volume changed and the other inputs held constant. The difference in water per irrigation then shows the effect of that assumption within this formula.

After calculating water per irrigation

Store the Container Watering Volume date, Container volume and Watering fraction, and Water per irrigation.

Separate measured container volume from an assumed value so a later user can reconstruct the case.

Add the garden outcome as a new entry, using the same units and definition as water per irrigation.

Container volume: sensitivity example

In a Container Watering Volume sensitivity check, compare container volume at 5 gal and 5.5 gal. Water per irrigation evaluates to 0.90 gal and 0.99 gal, respectively. The Irrigation Frequency Calculator provides days between irrigation.

Both cases hold watering fraction unchanged; preserve the other Container Watering Volume inputs too.

Prefer measured container volume ranges in Container Watering Volume. Vegetable Bed Water Volume Calculator calculates water for one inch separately.
