Why do I use Silica Stone? 2)The internal porosity allows the granules to absorb moisture and to slowly release it back to the plant as required. As a result of the uniquely shaped granules, the media achieves an excellent air to water ratio in the pot. This is particularly important to discouraging root rot while encouraging oxygen flow and healthy root formation.
Why do I use Silica Stone? 3) It does not break down like other media, and can used to successfully cultivate plants from seedling to specimen. Silica stone's composition is predominantly silicon dioxide, which results in the media slowly releasing silica to the plant, which is particularly important to cell growth.
Why do I use Silica Stone? 4) When lining the bottom of a pot with silica stone, the silica stone acts as a reserve reservoir so plants can get the extra moisture they need in the later stages of growth. They then slowly add micro-nutrients into the root zone for further growth and disease resistance.
And finally....Why do I use Silica Stone? 5) They do not roll around and under things when accidentally (and inevitably) dropped as does hydroton. Marbles everywhere!!!!
