     GRO-SILIC™ Soluble Silicon GRO-SILIC™ SOLUBLE SILICON is a concentrated liquid silicon supplement suitable for soilless and hydroponic systems. This plant-available form of silicon helps improve plant growth and vigor, in part by strengthening cell walls. Plants with improved cell wall structure are better able to endure periods of abiotic stress such as high temperatures and drought. Gro-Silic is very effective as a soil drench, but for fastest absorption apply as a foliar spray. Application Rate: 1L makes 6667L of solution. Foliar application: Dilute to 1:500 or greater. Apply at the 3 – 8 leaf stage and once monthly thereafter as required. Soilless/water culture application: For nutrient solutions apply at a rate of 0.15 – 0.30 ml/L (0.6 – 1.2 ml/gal.). KEY FEATURES Compatible With Beneficial Biology Improves Abiotic Stress Resistance Highly Concentrated, Plant Available Silica  Guaranteed Analysis  Boron (B)..... 0.009% Derived From: Boric Acid ALSO CONTAINS NON-PLANT FOOD INGREDIENT: 13% Soluble Silicon (Si) from Sodium Silicate 87.0% Total Other Ingredients (inert as non-plant food ingredient) MORE INFORMATION Silica is one of the most interesting supplements to add to a nutrient program. While not considered essential, silica assists numerous plants with abiotic stress. Gro-Silic™ has elevated levels of plant available silica to help with heat, drought, and salinity, providing improved uptake within plant structures when compared to other slower release forms of silica. Grotek Gro-Silic is a strong base and should never be added to nutrient concentrates. To avoid precipitation of nutrients, it is recommended to add Grotek Gro-Silic to nutrient tank and adjust pH to desired range prior to adding other nutrients. If adding to an existing nutrient solution, pre-dilute in a small amount of water. Check pH and adjust to 5.5 – 6.5 depending on crop requirement.

    1 in stock In stock

    Final Flush is a flushing agent designed to correct overfeeding issues during crop production and also eliminate excess salts from the medium during the final stages of plant growth. Salinity can become a serious issue for those gardeners growing in containers and recirculation systems. Salt buildup can cause problems for growing plants and bitterness in harvested fruit.The organic acids in this product help knock nutrients out from around the rhizosphere. Removing these easily accessible food sources causes the plant to search for new food sources.In many cases, plants have tucked away unconverted salts into surrounding tissues. This can lead to bitter-tasting produce. As the medium EC and nutrient availability is lowered, the plant takes any unconverted salts within its structure and properly metabolizes them which results in a cleaner harvest.
