Medtek Super Silica 1L

Introducing Medtek Super Silica

Super silica is the most concentrated agricultural grade liquid silica product on the market today.

When Super Silica is compared to most other brands, when applied at an equivalent ml/L usage rate, it proves to provide significantly more ‘Plant Available Silicon’ (PAS) to hydroponic solutions.

The quality of a silica product for use in hydroponics comes down to the amount (%) of ‘plant available Si’ (PAS) that any given product provides.

This can be accurately measured using the 5-day method for determining the soluble silica (Si) concentration.

The chemistry of silica in hydroponic solutions is extremely complex but, to put things simply, plants can only uptake monosilicic/orthosilicic acid (H4SiO4).

What this means is that only a percentage of any silica additive, when it is applied to solution, is available for plant uptake, i.e. when silica is added to aqueous environments (e.g. hydroponic nutrient solutions) chemical processes/reactions occur whereby non-bioavailable forms of Si become bioavailable as H4SiO4 and vice versa.

This peaks in acidic solutions (e.g. hydroponics where pH is below 7), no matter how much Si is added to solution, at no higher than 100-120 ppm dependent on prevailing conditions (higher concentrations of soluble monomers are only obtained above pH 11-12.)
