Substrate Bag Gutter 18.5cm PVC. This substrate bag gutter is pre-sized to fit standard 150 mm substrate bags. As a result, each plant gets its own block of growing medium with drainage underneath. It is engineered for single-plant cultivation in glass greenhouses and vertical hydroponic projects where consistency from plant to plant matters more than anything else.

The substrate bag gutter is used for strawberry, tomato, pepper, cucumber and small fruit production on substrate bags or blocks. It fits single rows on benches, hanging layouts and multi-tier vertical systems inside glass greenhouses. Also, it is the standard section for growers running a one-plant-one-bag programme.
Bags are laid into the gutter, drip stakes are set per plant. Also, the drainage base carries surplus solution to a return line for collection or reuse. Because the substrate bag gutter holds each bag in a fixed position, plant spacing stays exact and harvest trolleys can run the aisle without disturbing the row.
GNFORTUNE has manufactured substrate profiles in Guangdong since 2015 and supplies them to projects in more than 60 countries. Every substrate bag gutter is extruded from food-grade PVC, certified to RoHS and dimension-checked before packing. Also, we hold stock of the standard 18.5 cm profile for fast shipment.
