Grotek Root Force 4L, Supporting root development is key to crop success. Root Force™ aids in providing optimal nutrient conditions for the development of important secondary root structures. These structures can improve nutrient uptake, support connections with mycorrhizae, and build stronger plants by contributing to a more robust root system. This formula can help provide a buffer against abiotic environmental pressure such as drought and under-watering, giving plants a chance to bounce back quicker from stressful conditions. Root Force™ is designed to support biology, especially bacteria. This product also supports fungi, as it aims to support roots without added phosphorus - an element that can inhibit the development of some mycorrhizae.
