Grotek LXR Gold is a potassium supplement combined with low molecular weight humates. These humates are natural chelators, enhancing nutrient availability and absorption. LXR Gold can be used as a root drench to supplement an existing nutrient program or as a foliar spray for quick results when your plants show a deficiency in potassium (brown scorching and curling of leaf tips, reduced plant growth, root development, and seed/fruit development). Ideal for greenhouse vegetables and ornamentals. LXR Gold can be used in all garden types and is particularly well suited to water culture.
