Why Mirasand

More light. Better soil. No gnats.

  1. Reflects light upward

    Pale mineral grains bounce sunlight up into the canopy and reach the leaves that sit in shadow. Plants grow up to 30% bigger.

  2. Feeds the soil

    Every time you water, more natural minerals wash down into the soil. No chemicals, no synthetic fertilizer.

  3. Lets roots breathe

    Mirasand sits as a breathable layer, so air still reaches the roots. Decorative pebbles just seal the surface.

  4. Stops fungus gnats

    Fungus gnats lay eggs in damp, open topsoil. Mirasand covers it with a layer they can't dig through, so the next generation never hatches.

How it works

As simple as topping up

  1. Pour

    Spread about a centimetre of Mirasand over the topsoil, right up to the stem.

  2. Water as usual

    Each watering carries the minerals down to feed the soil below.

  3. Watch it respond

    Within a few weeks the leaves perk up and the gnats stop hatching.
