Setup guide

The Four by Four, start to harvest

  1. Place

    Set the saucer flat where the stack will live. Fill the first tier with one bag of Coco Soil and press it level.

    Stack the next tier on top, turned 45° on the one below, so each cup sits between the cups beneath it. Fill it, and repeat for all four tiers. Stack snug.

  2. Sow

    Colour is the map: each seed pack's label colour matches its group (leaves, herbs, roots, microgreens).

    Leaves and herbs go 1 cm deep, roots 2 cm. Microgreens are scattered on the surface.

  3. Water

    Water from the top tier until it runs through to the saucer, and check daily.

    Feed with Growth Formula: two pumps per litre of water. One bottle comes in the box.

  4. Grow

    Give it six to eight hours of light. Microgreens are ready in days, herbs in weeks.

    Short on light? The Halo Grow Lamp sits over the stack on a timer.
