| Use case | Final volume | Method | Setting | Concentrate | Water |
|---|---|---|---|---|---|
| Foliar feed | 5 l | Ratio | 1:200 | 0.025 l (25 ml) | 4.975 l |
| Soil drench | 2 l | Ratio | 1:50 | 0.039 l (39 ml) | 1.961 l |
| Nutrient mix | 10 l | Percent | 20% → 0.5% | 0.25 l (250 ml) | 9.75 l |
| Fertilizer target | 4 l | PPM | 200,000 → 1,000 | 0.02 l (20 ml) | 3.98 l |
Accurate dilution protects plants, improves coverage, and controls cost. Over‑strong mixes can scorch foliage, slow growth, and leave residues, while under‑dosing reduces pest and disease control. This calculator scales any recipe to your exact batch size, so a proven mix remains consistent across different sprayers, watering cans, and reservoir volumes. It also supports safer preparation by showing concentrate and water amounts clearly. Use the saved outputs to standardize staff training and reduce errors during busy spraying windows in greenhouses, beds, and container gardens.
Many garden products specify parts concentrate to parts water, such as 1:100 or 1:200. The calculator converts those parts into a fraction of the final volume: concentrate equals Vfinal × C/(C+W). Water is the remainder. This approach is best for soaps, oils, wetting agents, and general spray concentrates where the label uses simple ratios.
Some nutrients and additives are sold as solutions with known percentage strength. Using the dilution rule C1 × V1 = C2 × V2, the calculator finds the concentrate volume needed to reach a target percent. It helps with low targets used for seedlings, foliar feeding, and sensitive ornamentals, where small errors can double the effective dose.
Hydroponic schedules often use ppm targets rather than percent. Because ppm is proportional concentration, the same C1 × V1 = C2 × V2 relationship applies. Enter concentrate ppm and target ppm to compute precise dosing for buckets, tanks, or recirculating systems. This supports repeatable feeding, stable EC trends, and easier troubleshooting when plants show deficiency or tip burn.
Measuring tools have limits, so rounding to 1–50 ml can speed preparation without large drift. When rounding is applied, water is adjusted to preserve total volume. An optional allowance adds extra mix for hose, filters, and dead‑volume losses. CSV and PDF exports create a durable record for audits, seasonal comparisons, and continuous improvement of your garden program.
Use the ratio method when the label gives parts like 1:100. Use percent or ppm when the label states strength and a target concentration. If only application rate is given, follow the label directly.
Use a graduated syringe, pipette, or small measuring cylinder. Increase decimals, enable rounding to 1 ml, and mix a larger batch if your tools cannot resolve the required volume reliably.
Yes. Select the ppm method, enter concentrate ppm and your target ppm, then enter reservoir volume. The output gives the exact concentrate dose and the remaining water amount.
It increases the final batch by a chosen percent to cover liquid left in hoses, filters, and dead space. The calculator then recomputes concentrate and water so the applied mix stays on target.
The target must be lower than the concentrate strength. If they are equal or higher, dilution cannot achieve the target. Recheck label units, decimals, and any conversion assumptions.
They store your inputs and computed volumes for repeatability. Save files with the product name and date, and keep them with label instructions. Always verify the first mix with calibrated measuring tools.
