  • 02

    Steel Frame

    Galvanized structural steel A-frame support structure.

  • 03

    Intake Manifold

    Pressure compensated micro-tubing for equal flow.

  • 04

    Catchment Rail

    Gravity return gutter system to main tank.

System Analysis

The A-Frame system addresses the issue of horizontal space in medium-to-large operations. By angling the grow channels, we increase the planting area by roughly 300% without increasing the footprint.

This design uses the Nutrient Film Technique (NFT), where a shallow stream of water containing all dissolved nutrients recirculates past the bare roots of plants in a watertight gully (channel). A mat of roots develops in the gully, taking up oxygen from the air above the flow.
