Wall-Mounted NFT Hydroponic System

A wall of salad and herbs, 165 mm deep: shallower than a bookshelf, on a wall you already walk past. Four growing channels, fed automatically from a 100 L reservoir underneath. No digging, no weeds, no watering: a small pump circulates the nutrient solution past the roots and back. You top up the tank every week or two and pick what you need.

Two sizes, both complete kits

• 1.5 m, R4,500: 28 plants. Unit height 1.2 m, tiers 300 mm apart, ceiling needed 2.02 m.
• 3 m, R6,500: 56 plants on the same tank, pump and power. Unit height 1.5 m, tiers 400 mm apart, ceiling needed 2.33 m.

Both: 165 mm off the wall, 100 L reservoir, 1,400 L/h pump, 28 W running the whole system.

It arrives built

We cut the channels, drill every grow hole and make up the brackets before it leaves us, so mounting it is a morning with a drill rather than a project.

What is in it

Four growing channels (1.5 m or 3 m) with end caps, grommets and elbows; the mounting clamps, uprights and wall anchors; a 100 L reservoir; a 1,400 L/h pump; the feed pipe; and net pots (28 or 56). Plus everything to plant it the day it goes up: a HortiMix nutrient kit, a rockwool growing slab, pH up and pH down, a pH test kit and pipettes. Nothing else to buy.

What grows

Leafy greens and herbs: lettuce, spinach, rocket, basil, coriander, mint, chives, kale. The 1.5 m tiers sit 300 mm apart, which suits leafy greens and cut herbs; the 3 m's 400 mm gives room for bushier crops. Not tomatoes, peppers or root vegetables.

Light

Good natural light: a north-facing wall, a bright patio or a balcony. There are no grow lights. Deep shade will not work.

Installation

In Cape Town and the surrounding areas we can fit it: we mount it, plumb it, fill it and leave it running. Installation is quoted separately. Anywhere else, it arrives built and ready to mount.
