Potassium Silicate 20 Litre - K2O + SiO2 use 1ml per litre

Horticultural Potassium silicate is used as a soluble source of Potassium & Silica. Used as a supplement in your garden it has numerous benefits, increasing the availability of silicon compounds which are valuable to a plant. Plant stems thicken, the plant becomes more tolerant to drought and resists wilting, and the plant will benefit with larger leaves and flowers - fruit. The thicker cell walls of the plant also provides an added mechanical resistance to sap sucking insects like spider mite and various pathogenic fungi like powdery mildew

  • Use 1ml per litre of stock solution, the product works best when diluted before adding to your main reservoir - tank.
  • 1ml per Litre equates to 1000ppm of product which yields K2O at 27ppm and SiO2 at 53ppm, you can increase to 2ml per Litre if a higher ppm is required
  • Stronger plants with thicker stems can support more weight
  • Provides a mechanical resistance to sap sucking insects and various pathogenic fungi 
  • It will make the growing medium and reservoir stock solution slightly more alkaline
  • 24 hours after you have dosed your reservoir tank you should check your pH levels and adjust as required

Most crops have a recommendation of 50-100ppm, and always start at lower level until you are confident with your dosage. Some varieties and crops will begin to show deficiencies of other minerals if Silica is too high.

Crops grown with potassium silicate have higher chlorophyll concentrations in their leaves than crops grown without them. More chlorophyll means more power to use the nutrients in its environment to reach its maximum size and production. 

Crops are also healthier for anybody who consumes them. When toxic heavy metals like lead and arsenic are present in a growing environment, they travel up plant roots alongside the nutrients the plants need. Everything the plant takes in ends up in its final product. Potassium silicate or silica keep heavy metals from reaching crops, by creating a rock solid barrier around plant cell structures.
