Calculate nutrient concentrate volume for a vertical-farm reservoir from the reservoir size and the concentrate label rate. A strength adjustment lets you scale a reference recipe when the working concentrate differs from the product used to establish that recipe.
Percent inputs are divided by 100 in the calculation. Unit conversions are shown in the results where applicable.
The result scales a manufacturer or crop-recipe dosing rate to the full reservoir and adjusts for relative concentrate strength. It does not predict EC, pH, or individual ion concentrations.
Confirm compatibility, add concentrates separately as directed, and check EC and pH after mixing. Never combine incompatible stock solutions undiluted.
A 2,000 L reservoir at 2.5 mL/L needs 5,000 mL at equal strength. If actual concentrate is twice the reference strength, the adjusted dose is 2,500 mL.
Yes, as a scenario estimate. Replace the defaults with measured operating data and keep a separate contingency for variability.
Calculate shorter periods with consistent assumptions, then add the period results. This is more reliable than using one blended value.
Use the most likely measured value for the base case, then recalculate with conservative and optimistic assumptions to see the planning range.
Equipment performance, biological variation, environmental conditions, measurement error, and downtime can all move the actual result.
No. The calculation runs in your browser and this page does not need to send the entered values to a server.
