itaSilica is compromised of approximately 87-94% silicon dioxide, plus small amounts of various other oxides including iron, calcium, potassium, titanium, manganese and phosphorous. The slow, continuous release of silica ensures increased resistance to pests and disease, bigger root systems and ultimately a higher yield.
 
VitaSilica is also a safe, organic treatment for eradicating crawling insects on the surface of your media. When you look at VitaSilica under a microscope it resembles a random pile of tiny razors. These ultra-sharp edges cut through an insect’s protective covering, sucking all the moisture out of them until they die. If an insect is stupid enough to try to eat VitaSilica this delightful process occurs from the inside out. VitaSilica is effective against fungus gnats, aphids, nematodes, slugs and snails. Our friendly earthworm is safe from VitaSilica’s wrath, which is good news all round.
 
How to use VitaSilica
Before using, thoroughly saturate VitaSilica in clean water for about an hour.
VitaSilica can be used to replace perlite, clay pebbles, as well as other growing mediums. VitaSilica can be used in both pots and re-circulating systems.
Simply place VitaSilica in pots in the same way as you have used other growing medias.
Place roots or seeds in a safe and stable position.
We advise that the granules are always rinsed through with water prior to use.
When using VitaSilica in a recirculating system, there may be some dust which runs down into the nutrient solution. There is no need for concern.
