SILICA is a concentrated blend of silicic acid and potassium hydroxide (called potassium silicate). Considered the superior form of silica for plants.
There are so many benefits using silica for your plants:
* Improves nutrient uptake and transportation throughout the plant.
* Increases plant resistance to fungal and insect attacks by strengthening cell walls.
* Increase stress resistance 
* Increases chlorophyll production in the leaves, leading to better photosynthesis 
* Increases the uptake of available CO2.
Important notes:
Always dilute GT SILICA in a separate 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 tí between 5.5 and 6.5
Add GT SILICA once per week
