Coir twine is often used in hops farming as a sustainable and biodegradable alternative to traditional synthetic twine. It provides support for the hops plants to grow upwards, aiding in their vertical growth and maximizing sunlight exposure. Coir twine is made from coconut husks and is resistant to moisture and decay, making it suitable for outdoor agricultural use. Its natural fibers are also less likely to damage the delicate hops vines compared to rougher synthetic materials. Overall, coir twine is a popular choice for environmentally conscious hops farmers.
