Grotek Pro Silicate (0-0-4)

With a high concentration of soluble potash and silica, Pro-Silicate™ was developed for use in soilless media and hydroponic systems where these elements may be lacking. While not considered an essential nutrient, plants accumulate silica in macro proportions for good reason.

Silica is known to strengthen cell walls and overall cell integrity, which makes plants more resistant to abiotic stress such as heat and drought.  

Why Grotek Pro-Silicate?

• Strengthens cell walls
• Increases resistance to abiotic stress
• Increases plant cell integrity
• High concentration of soluble potash and silica
• Improves conditions for drought tolerance
• Supports higher yields

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.
