With a high concentration of soluble potash and silica, Grotek™ Pro-Silicate™ (0-0-4) 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.
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.
Use Pro-Silicate during vegetative and reproductive growth. Watch pH as Pro-Silicate is a strong base.
Application Rate: Application Rate: 1L makes 2000L of solution. Pro-Silicate is a strong base and should never be added to nutrient concentrates. It is recommended 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.
