This plant display is made up with a pot plant, filled with Vulkastrat and is equipped with a waterlevel indicator. Vulkastrat absorbs more water than regular soil and releases it gradually to the roots. Vulkastrat cannot shrink shut due to its coarse structure, which keeps the soil more airy and allows the roots to absorb enough oxygen. If the planter is not waterproof, a liner is used to make the plant display waterproof.
