Grow Media Ordering & Volume Calculator

Use these tools to estimate plant count, unit needs by ordering cadence, and loose-fill media volume. Guidance only—validate with your cultivation plan, container specs, and lead times.

Used with spacing to estimate plants in flower.
Typical spacing varies by cultivar, training, and room layout.
If entered, override becomes the plant count used below.
Choose based on onsite storage and receiving cadence.
Minimum buffer is 5 business days.
Tip: select a package type to return only that recommended quantity.

Nutrient Planning & Mixing Calculator

Use these tools to plan targets and batch mixes. Guidance only—always follow your nutrient manufacturer’s feed chart, crop requirements, and local water conditions.

Select how you deliver nutrients to display relevant mixing guidance.
Used for conversions and planning totals.
Conversion: ppm = EC × scale.
Starting EC before nutrients.
Enter your final target as EC or PPM.
ppm stock
If you run a concentrated stock (injector / mother tank), add its ppm to estimate required stock volume.
Used only for a simple proportional split estimate across components (not a brand-accurate recipe).
Enter rates from your label/feed chart for each component.
Optional: Stock / injector helper (operational)
Example: 1000 ppm stock.
Example: 100 ppm final.
If set, we also show volumes for a 1:X dilution of the same V2.
Custom Feed Charts (Phase 2): Brand-specific feeding schedules (week-by-week) with printable charts and SKU forecasting.

For now: select a brand, set veg/flower weeks, and generate a printable schedule table scaffold. Use the official PDF as the authoritative reference.
This is Phase 2. We will later pull exact week-by-week doses per product line.
For now, this only affects table labels (not brand-accurate dosing).

Nutrients Program & Ordering Size

Build your nutrient program by application cadence. This estimator converts dilution rates into total mL / grams, then translates totals into packaged SKU counts per ordering frequency (with a transit/receiving buffer). Guidance only—always follow manufacturer feed charts, crop requirements, and local water conditions.

Facility inputs

Used to estimate daily mixed solution volume.
Optional. If your total mixed solution includes runoff, add it here.

Tip: rename the component field to match your nutrient line. Add rows for any supplements you run.

Purchasing note: choose frequency based on onsite storage capacity and lead times.
Minimum buffer is 5 business days.

Sanitation & IPM Mixing Toolkit

Use these calculators to mix cleaning and pest-management solutions consistently and to support purchasing workflows. Guidance only—always follow label directions, PPE requirements, compatibility rules, and local regulations.

Cleaning / Sanitation Dilution

Used only to tailor operational guidance text.
Choose the way your product specifies dilution.
Example: 1 fl oz/gal, or 2 mL/L.
If provided, we estimate solution needed for an area (below).
Used only if coverage rate is provided.

IPM / Pest Control Dilution

Guidance text changes based on method.
Enter the product’s label rate for the final solution.
If provided, we estimate solution volume for an area (below).
If you mix a stock tank for injection, add stock strength to estimate stock volume needed.

Concentration Volume Ratio

Example: 100 (any consistent concentration unit).
If set, we also show a 1:X split for the same V2.

Program Forecast & Ordering Size

Forecast concentrate consumption by ordering frequency. This estimator converts your dilution rate and mixed-solution usage into concentrate quantities and package counts, including a minimum transit/receiving buffer.

Facility inputs

Example: 2 events/week for IPM sprays, or 1 deep-clean/week.
Optional: add if you typically over-mix or lose volume.

Dilution & package sizing

Use liquid units for liquids; weight units for powders.
Purchasing note: choose frequency based on onsite storage capacity and lead times.
Minimum buffer is 5 business days.

Propagation Materials Calculator

Weekly estimator for starter plugs/cubes, trays, domes, cloning gel volume, and optional heat mats. Includes a loss factor to reduce production gaps.

Cycle inputs

Total cuttings you plan to stick each week.
Used for reporting and future SKU mapping.
If Yes, we estimate trays from cuttings and tray cell count.
If Custom, enter cells per tray below.
Assumes 1 dome per tray when trays are used.
If enabled, estimate 1 mat per rack level.
Typical range: 0.3–1.0 mL depending on method.
Default 5–10%. Covers typical losses and re-sticks.

Propagation Supplies Forecast & Ordering Size

Forecast plug/cube and cloning gel purchasing quantities based on weekly production, rack capacity, loss factor, ordering cadence, and a minimum transit/receiving buffer.

Facility inputs

Weekly production target (sticks).
How many propagation racks are in use.
Used to estimate capacity when “Total cuttings/rack” is not provided.
Propagation shelves/tiers per rack.
If filled, this overrides size-based capacity estimate.

Propagation assumptions

Typical range: 0.3–1.0 mL depending on method.
Default 5–10%. Covers typical losses and re-sticks.
Used to compute an order quantity per PO.
Minimum 5 business days recommended.
Used to convert business-day buffer into “weeks of demand”.
