  • Soil biology

    The root runs a factory: the plant pays in carbon, microbes deliver the rest.

  • Canopy wind speed: two sets of numbers

    Medical cannabis trials point to 1 to 2 m/s at the canopy. Tomato and sweetpotato work levels off by 0.5 to 1.

  • Mycorrhizal fungi spores go on the roots

    Spores do not move. Dust the rootball at every up-pot.

  • Magnesium: what it does

    The atom at the centre of chlorophyll. Green veins, yellow between, on old leaves.

A microscope in the Seacliff Organics soil lab

Recipes set by soil tests, not guesswork

Every Seacliff blend starts with lab data: mineral analysis from Logan Labs and Soil Food Web microscopy of the biology. The living soil is balanced to strict targets so it can be run water-only, recycled and re-amended season after season.

Ingredients are sourced locally where possible and sold dry, without water, so you pay for nutrients rather than freight.
