Silicon is the second most abundant element in the earths crust making up a component of most rocks. Plants absorb silicon from silica that has dissolved into the soil water. As you can imagine the concentration of silicon in soil water is not that high because rocks do not tend to be all that soluble.

Silicon concentration in soil water generally does not get above 20 ppm and this is the level we recommend for hydroponic nutrient solutions.  

Silicon is a beneficial plant nutrient found in virtually all soils but not, until now, in hydroponic nutrient solutions. Silicon will strengthen plant cell walls and become a barrier against water loss, fungal infection, particularly mildews, and insect and mite attack.

Silicates are very alkaline and care must be taken with its use. Always check the pH after silicon has been added to the tank.

Application :

For use during the vegetative and flowering cycle dilution guide.


FULL STRENGTH 5mL per litre of nutrient solution.

IMPORTANT Always dilute GT SILICA in a seperate container of fresh water before adding to the nutrient solution.

1. Add diluted GT SILICA to the nutrient solution slowly.

2. Mix thoroughly and allow to stand for 15 minutes. 

3. Adjust pH between 5.5 and 6.5


Add GT SILICA once per week


Add when preparing the nutrient solution. 


  • Improves nutrient uptake and transportation throughout the plant.
  • Increases plant resistance to fungal and insect attack by strengthening cell walls.
  • Increases chlorophyll production in the leaves, leading to better photosynthesis.
  • Increases the uptake of available C02.
