HG-40 · HG-25
Hanging gutter HG-40
For high-wire tomato, cucumber and sweet pepper on stone wool or coir. The gutter hangs from the truss on adjustable suspensions, with a spacer that keeps the slab out of the drain water.
Detail section
Suspension, profile, spacer, slab and drain channel.
The spacer keeps the slab 12 mm above the drain channel, so roots never stand in drain water.
