Liquid Silicon by Growth Technology is used by plants for many things including: the creation of strong cell walls; the production of chlorophyll; and the transportation of minerals. By adding liquid silicon to your tank, you can help improve the strength of stems and therefore the amount of weight they can support. Strong cell walls also reduce the damage done by pests and diseases, making it easier for your plants to resist any infestations that may occur during a grow. Liquid silicon also has a high pH level, meaning it can be used as an effective pH up with the added benefits that silicon can bring to your plants. It is available in 1L and 5L bottles.
