About this item
Product details
Old Cobblers Farm™ Wicked Thick Skin is a concentrated North Atlantic seaweed extract powder designed to support strong roots, healthy growth, and resilient plants. Made from Ascophyllum nodosum seaweed, this highly soluble kelp extract dissolves easily in water to create a nutrient-rich plant supplement suitable for vegetables, flowers, houseplants, container gardens, and landscape plants. Naturally occurring trace minerals and plant compounds help encourage balanced growth, improved root development, and stronger plant structure, allowing plants to absorb water and nutrients more efficiently. Healthy roots support steady growth, vibrant foliage, and productive plants throughout the growing season. This versatile formula can be used during seed starting, transplanting, and routine plant care to help maintain consistent plant performance in many growing environments. The easy-mix powder quickly turns into a liquid solution for soil drenching or plant spray applications, making it simple for both home gardeners and experienced growers to use. When applied to soil, seaweed extract also supports beneficial soil activity that contributes to better nutrient availability and improved soil quality. With a concentrated formula where a small amount prepares multiple gallons of solution, Wicked Thick Skin is a practical and efficient plant care option for indoor plants, garden beds, raised planters, and container gardens. Guaranteed Minimum Analysis: Soluble Potash (K₂O) 15% derived from seaweed extract.
