Custom Hydro’s custom micronutrient formulation service develops a trace element mix around your requested nutrient concentrations for hydroponics, fertigation, or constant liquid drip feeding.

This $200 purchase covers the formulation service and a cost quote only. Physical fertilizer is not included and is quoted separately.

How the formulation service works

1. Purchase the formulation service. We will send you a link to a form for your requested trace element concentrations.
2. Specify your targets as percentages or ppm (mg/L). When providing ppm targets, explain the intended dilution and use so the calculation basis is clear.
3. Custom Hydro performs the calculations and contacts you with any questions or the cost of the proposed mix.

Micronutrients and source options

Mixtures include iron, copper, manganese, zinc, boron, and molybdenum. Chelated or sulfate sources are available for iron, copper, manganese, and zinc. Boron source options include boric acid and Solubor. The final formula depends on your specifications and formulation feasibility.

Batch size and fertilizer quote

Custom mixes are prepared in 100-pound batches. The physical fertilizer price depends on the formula selected. Historically, 100-pound batches have cost $1,000–$2,000; this is background pricing, not a fixed quote for your formulation.

There are no refunds on the formulation service.

The pail image is an illustrative example of custom-mix packaging. Its 25-pound label does not change the 100-pound batch size or mean that fertilizer is included with this service.
