Grotek Pro Silicate


Grotek Pro Silicate  was developed for use in soilless media and hydroponic systems where these elements may be lacking.


Grotek Pro Silicate

Use Grotek Pro Silicate during vegetative and reproductive growth. Watch pH as Pro-Silicate is a strong base.

While not considered an essential element for most crops, silica helps virtually all plant species on the planet by supporting strong cell wall development.  Rigid cell walls are crucial for tolerance of abiotic stress such as heat and drought, which prevents wilting and ensures strong plant performance.  With two sources of potassium (potassium silicate and potassium chloride), Pro-Silicate adds the nutrients necessary for improved flowering and fruiting.

How to Use:
  • Application Rate: 1L makes 2000L of solution
  • Pro-Silicate is a strong base and should never be added to nutrient concentrates
  • We recommend that Pro-Silicate be added to the nutrient tank prior to the addition of nutrients
  • Soil/Soilless/Water Culture: Mix ½− 1 tsp per 1 gal of water (2½−5 ml / 4 L)
  • Check pH and adjust to 5.5−6.5
  • Agitate well, then add nutrients

If necessary, Pro-Silicate can be added to the nutrient tank after nutrients are in a solution. Pre-dilute in a small quantity of water and add slowly while agitating.

NOTICE: This method can lead to the formation of precipitates if the pH fluctuations are too high.
