How FlahaFAST supports nutrient formulation, source-water contribution and A/B stock-tank preparation workflows.
Document revision: 2026-07-20
Scope
FlahaFAST supports fertigation and hydroponic nutrient formulation workflows, including source-water contribution, salt balancing and practical stock-tank preparation.
Purpose
Provide disciplined, reviewable nutrient-calculation workflows that improve transparency and reduce formulation error risk under production pressure.
Typical inputs
- Source-water analysis
- Crop or solution nutrient targets
- Available fertilizer salts and constraints
- A/B tank volumes and operational limits
Typical outputs
- Balanced nutrient programmes
- Fertilizer recipes and stock-tank instructions
- Compatibility / verification oriented checks
- Traceable calculation records for professional review
Units & measurement notes
| Quantity | Typical units | Notes |
|---|---|---|
| Ion concentrations | mmol/L, meq/L or ppm (as configured) | Always confirm basis before comparing packages. |
| EC of solution | dS/m or mS/cm | Operational check, not a full ion diagnosis alone. |
| Fertilizer mass | g or kg per tank volume | Stock recipes depend on purity and hydration assumptions. |
| Tank volume | L or m³ | A/B stock practicality constraint. |
Key indicators
- Target vs achieved ion balance
- Source-water ion contribution
- Salt selection feasibility
- Compatibility / precipitation risk flags
- A/B stock recipe practicality
Scientific engines
- Nutrient balancing logic
- Source-water ion contribution accounting
- Salt selection and formulation checks
- Stock-tank recipe generation and verification views
Calculation notes
- Formulation starts from targets, subtracts or accounts for source-water ions, then allocates fertilizer salts within operational constraints.
- Compatibility checks are decision-support signals; laboratory confirmation and on-site observation remain required for high-risk mixes.
- Stock-tank recipes are operational documents—purity, moisture and weighing discipline affect real-world results.
Standards & documentation status
Formulation practice follows professional fertigation and soilless nutrition discipline. Detailed chemistry references, compatibility matrices and engine revision history expand under scientific review.
Validation status: Public methodology: structured overview. Formal validation cases and versioned chemistry rule tables pending scientific packages.
Engine / methodology version: Public marketing methodology v0.9 (overview)
Assumptions
- Water analyses and fertilizer compositions are accurate and current.
- Operators verify tank preparation, mixing order and safety controls on site.
- Crop response depends on environment and management beyond formulation alone.
Limitations
- Does not replace plant diagnostics or pathology investigation.
- Does not guarantee yield or quality outcomes.
- Local regulations, salt purity and operational safety remain operator responsibilities.
