Estimated Savings
Research basis:
Disclaimer: Estimates are based on published scientific data (FAO, ICBA, peer-reviewed studies). The "Conservative Estimate" represents typical field conditions (~50% of the research maximum). The "Optimistic Estimate" represents results under ideal conditions. Actual results depend on crop variety, climate, irrigation practices, application rate, and local conditions. We recommend consulting with our agronomists for a personalized analysis.
The Science Behind Our Numbers
Perlite in Sandy Soil
Fine expanded perlite applied to sandy soils reduced irrigation needs by 50% in a field trial, while maintaining healthy plant growth.

Zeolite & Water Retention
Clinoptilolite zeolite application increased available soil moisture by up to 50% in sandy soils, with 7–10% moisture increase in loamy-sand soils.

Hydroponics vs Traditional
Hydroponic systems can reduce water use by up to 90% compared to traditional open-field agriculture. This refers to the cultivation method, not the substrate alone.

Crop Water Requirements
Per-crop water consumption values are based on Table 14 of FAO Irrigation & Drainage Paper 24, adjusted for Mediterranean climate (mid-to-high range values).
Source: FAO, "Crop Water Needs" — Typical range mm/growing season (1 mm = 10 m³/hectare)
Calculation Methodology
- Water consumption: Mediterranean climate values (mid-to-high of FAO range). 1 mm rainfall over 1 hectare = 10 m³ of water.
- Conservative estimate: 50% of the maximum research value × soil modifier. Represents typical field conditions.
- Optimistic estimate: 100% of the published research value × soil modifier. Represents ideal conditions.
- Soil modifier: Sandy = 1.0× (research baseline), Loam = 0.5×, Clay = 0.2× — because most trials were conducted on sandy soils.
- Vermiculite: The "3–4× weight in water" is a material property, not a field trial result. Irrigation reduction is estimated conservatively.
- Hydroponics: The 90% saving refers to the method (hydroponics vs open field), not exclusively the substrate product.
