Greenhouse, Indoor Farming & Agri-Processing calculator

Nutrient mix consumption calculator

Size the A/B stock or fertigation concentrate volume needed for a crop cycle by multiplying canopy square footage by daily nutrient solution use per square foot, then dividing by your dosing-system efficiency to account for line losses, batch-tank carryover, and EC drift bleed-off. Use the result to schedule fertilizer purchases or to know when to mix the next batch.

What this calculator does

  • Estimate liters of A/B nutrient stock or fertigation concentrate needed to feed a hydroponic, NFT, ebb-and-flow, or drip-irrigated canopy from growing area, daily nutrient solution use per square foot, and dosing-system efficiency.
  • Use it when sizing a tote or batch-tank refill for the next crop cycle, checking whether on-hand stock covers a holiday weekend, or planning fertilizer purchase orders for a leafy green, herb, tomato, or cucumber program.
  • Turns active canopy area to feed, daily nutrient solution use per square foot, dosing-system delivery efficiency into a required quantity for nutrient mix consumption in greenhouse, indoor farming and agri-processing.

Formula used

  • Theoretical daily solution required = active canopy area × daily nutrient solution use per square foot
  • Required nutrient solution to mix = theoretical daily solution required ÷ dosing-system delivery efficiency

Inputs explained

  • Active canopy area to feed: Enter productive canopy under cultivation across all benches, racks, gutters, or plug trays for the period being budgeted.
  • Daily nutrient solution use per square foot: Use measured fertigation volume per sq ft per day from your irrigation controller or runoff log; leafy greens typically 0.05-0.15 L, tomatoes 0.3-0.5 L.
  • Dosing-system delivery efficiency: Share of mixed solution that actually reaches plants after line losses, drain-to-waste, EC bleed-off, and batch-tank residual; usually 80-95%.

How to use the result

  • Use it when nutrient mix consumption in greenhouse, indoor farming and agri-processing is going on a PO and you want a defensible buy quantity.
  • Pack-out, min-order quantity, and supplier lead time are not modeled; layer them on top.

Common questions

  • What problem does this nutrient mix consumption calculator solve? Estimate liters of A/B nutrient stock or fertigation concentrate needed to feed a hydroponic, NFT, ebb-and-flow, or drip-irrigated canopy from growing area, daily nutrient solution use per square foot, and dosing-system efficiency. You get a required quantity you can defend before quoting, scheduling, or sign-off.
  • Which inputs change the required quantity the most? active canopy area to feed, daily nutrient solution use per square foot, dosing-system delivery efficiency usually move the required quantity most. Pull from measured greenhouse, indoor farming and agri-processing runs, supplier data, and recent quotes rather than memory.
  • What do I do with this number? Use the required quantity as your PO line, plus whatever min-order or pack-out rules apply.
  • What should I double-check before acting? Confirm efficiency reflects current setup; efficiency drifts after tooling changes.
