Why Sand Is the Perfect Growing Medium
Although sand has traditionally been overlooked as a planting medium due to its fast drainage properties, it actually provides the ideal growing environment for most plants. The adhesion and cohesion properties of water create surface tension and capillary rise within the sand profile.
Washed sand media delivers the perfect combination of stability without compaction and optimal aerobic air-water ratios in the root zone—without ever being overwatered. With EPIC, plants themselves determine when to drink and when to breathe.
Think of EPIC as a water battery for plants, recharging slowly to perform efficient water distribution at nature's pace.
How EPIC Works: Scientific Principles
Water is introduced directly to the roots from the inlet. As plants transpire, new water automatically replaces what's used, moving upward into the root zone by capillary action from the sub-surface reservoir.
Similar to a natural stream embankment, the water film extends through capillary rise, whilst high oxygen levels in the sand voids create an ideal environment for robust plant growth.
Our patented technology finely controls physical parameters in sand media, allowing plants to autonomously regulate their water intake, respiration, and nutrient absorption—exactly as nature intended.
Key Features of the EPIC System
Superior Drainage
The EPIC chamber is the world's best drainage pipe. Non-clogging, patented offset interface holes provide exceptional drainage capabilities. Approved gravel profiles drain 1" of water in 15 seconds, while established turf profiles can handle world-record rainfall events of 23" in 24 hours without surface pooling.
Advanced Filtration
Provides aggregate filtration, passive oil and grease separation, and bio-filtration of contaminants via nutrient uptake by landscape plants. The system supports customised filtration techniques and microbiological degradation for superior water treatment.
Efficient Sub-Irrigation
Delivers non-pressurised, passive sub-surface irrigation with minimal evaporation loss and 100% efficiency. The secret lies in capillary physics, creating a water battery for plants that recharges for long-term performance.
EPIC Scientific Principles utilise locally approved bridging aggregates (gravel and sand) to drain, sub-irrigate, and sustain H-30 loads effectively. The system has no moving parts, with sand being the secret to its remarkable performance and efficiency.

EPIC Agriculture: Sand Hydroponics Benefits
100% Efficient Sub-Irrigation
Passive, non-pressurised sub-irrigation ensures every drop of water is utilised efficiently.
Temperature Regulation
High-BTU-value heat sink buffers root zone temperatures, while recirculating air exchange can augment greenhouse heating or cooling needs.
Sustainable Operation
No growing medium exchange needed for the life of a greenhouse, no tilling required, and direct seed germination possible for most crops.
Superior Crop Quality
Produces "Better than Organic" crop quality with sub-fertilisation or fertigation options, all whilst being highly cost-effective.
Expert Testimonials
"The Greens with subsurface ground irrigation (EPIC) used 50-70% less water with better turf quality than standard USGA Greens."
Dr. Bernd Leinauer, PhD, Assistant Professor and Extension Turf Grass specialist at NMSU
"For the construction of public facilities in the State of California, installation of the EPIC system is a no-brainer."
Myke Praul, P.E., Public Works Director/Town Engineer, City of St. Helena, California
"The EPIC system has performed beyond our expectations and the EPIC team has been extremely responsive to answer operational questions and working through start-up issues as they arose."
James K. Stickley, ASLA, LEED AP, Principal
These testimonials from industry experts and professionals highlight the exceptional performance, water efficiency, and versatility of the EPIC system across different applications.
Simple Installation & Modular Design
The EPIC system features a modular construction that makes installation and expansion straightforward:
  • Self-contained, gravity-driven "EPIC Cells" connect to form the complete system
  • New systems can be added to established ones in multiple phases with ease
  • Sub-grade is installed with a laser level, which is less expensive than creating sloped grades
  • Elevate EPDM liner is simply rolled out
  • EPIC chambers interconnect with sand-tight connections requiring no gluing
  • The system is buried with approved gravel layer and sand aggregates
The impermeable EPDM liner prevents water loss to the ground table, ensuring every drop of water is used within the growth profile for maximum efficiency.
