Environmental Passive Integrated Conveyance (EPIC) SystemPassive Irrigation with Sand Hydroponics

Beans grown in identical sand beds.. The roots on the left were irrigated by capillary rise in an EPIC planter. The roots on the right were conventionally top watered.


Small and Large EPIC Chambers

Large and Small EPIC Chambers offer versatility different applications of water management.  Both EPIC chamber sizes offer unique qualifications for passive irrigation and drainage features.  The small chamber can fit in tight spaces buried in gravel as a drain filter.  The large chamber offers more air space inside to contribute to the microbiological degradation function in EPIC septic systems.  In combination, both EPIC chambers offer superior performance.  The EPIC chamber is the world’s best French Drain that never clogs… and EPIC has the additional feature of sub-irrigation too!

EPIC TWS passive irrigation are sand hydroponic planting systems, where plants grow in sand and not soil.  Although sand generally has not been recognized as a planting media due to its fast drainage, sand is actually a preferred growing media for most plants. Adhesion and cohesion properties of water create surface tension and capillary rise within the sand growing profile.

Washed sand media provide the perfect combination of stability without compaction and aerobic air-water ratios in the root zone without ever being over-watered.  The plants themselves make the decision of when to drink and when to breathe.

Water is introduced directly to the roots from the inlet.  As water is transpired by the plant, new water is automatically replaced upward into the root zone by capillary action from the sub-surface reservoir.  The water film from capillary rise and high oxygen levels among the sand voids provide an ideal growing environment for plant growth.

Irrigation demand is dramatically reduced as every drop is utilized for exceptional plant growth!

A greenhouse test compared 750 cucumber plants, the EPIC System used 72% LESS water, 50% LESS fertilizer, and produced 300% MORE crop than the adjoining conventional drip system.

The secret is that EPIC uses every drop to achieve 100% efficiency.

Planter Conversion Kits

Economical and easy, convert any sized planter.  There are large and small kits that allow you to convert any planter to a sand hydroponic planter.  Use it for outdoor or indoor planters of any size or shape. Recommended for planter height of 12″ or larger.



EPIC Garden Kit

4′ width x 15″ height x 8′ length.  You can construct an EPIC sand hydroponics raised garden bed for flowers, plants and vegetables grown outdoors or in greenhouse applications.  Link together garden kits to form larger areas, connected by gravity distribution, to be simply irrigated from a single point source at the beginning of your garden.  Water flows through the non-pressurized EPIC chambers and irrigates the sand hydroponic gardens.


Premier Raised Garden Bed

This very easy to assemble kit is made of 1.5″ thick Redwood side walls, pre-cut and taped 45 mil EPDM liner, and EPIC chamber with connections.  Assembled it forms a 4’x4’x16″ deep raised garden bed ready for washed sand fill. Very rugged and strong construction, it will provide a lifetime of prolific garden use without and seasonal “soil” replacement.  The plants grow in sand hydroponics, not soil.


EPIC garden planter

Small EPIC Garden Planter

Economical and Easy, convert any sized planter. The kit allows you to convert any planter to a self watering sand hydroponic planter. Use it for small outdoor or indoor planters of any size or shape. Recommended for use with a planter base ranging 8″-16″ width.
