Silic Rock is a silicon-based fertiliser that helps plants combat a hidden issue: silicon deficiency. This unique fertiliser enhances nutrient absorption in plants and strengthens their cell walls to increase resistance. Silic Rock contains easily absorbable silicon, which is essential for plants to improve nutrient absorption. It strengthens cell walls, resulting in healthier, stronger plants. To use, simply add up to 1 ml of Silic Rock per liter of water and use the solution during the entire cultivation period whenever the plants are irrigated. Silic Rock is not recommended for hydroponic cultivation methods such as nutrient film technique (NFT), deep water culture (DWC), and aeroponics. It is available in 250 ml, 500 ml, and 1 L bottles.
