Activated Potassium Silicate

0-0-2, 4% silica dioxide

Silica is one of the most abundant elements on earth, yet is not available for plants. Silica reacts with calcium inside the plant, especially near the outer cell wall. This provides a physical barrier to reduce molds, mildews and insects attacks while building stronger branches and stems for heavier bud development. The desired amount of potassium silicate in exotic plants ranges from 80-100ppm.

Offered in the following quantities:

  • 1L
  • 4L
  • 10L

[accordion heading="More Info"]

Silicon can help to improve the development of cannabis by speeding up the production of the cell walls.

It is used to build a framework of cells out of silica and cellulose, it acts as a cement which results in a boost of overall performance. Derma Guard creates strong sturdy branches that resist pest fungi and molds. Derma Guard is alkaline in nature therefore increases the pH level of the nutrient solution adjust accordingly.

Derma Guard can be used for both vegetative and flower stage eliminating 7-14 days prior to harvest.


[accordion heading="Directions"]

  • Foliar application rate: 1 ml/L (40 ppm)

  • Root Feeding rate: 2ml/L (80 ppm)

*When mixing always add potassium silicate/Derma Guard first in your container before other nutrients. If using reverse osmosis water this will allow your pH pen to now read your inert liquid (you will ruin your pH pen if you try and read the pH of reverse osmosis water without a stabilizer added).
