"Green Stripe" 250' x .820 Bulk Soaker Hose offers the perfect delivery of water to plants. Made from recycled materials, 70% from recycled rubber and 30% recycled polyethylene products that are re-pelletized for use in the process. Bulk Soaker hose means there are NO fittings on the hose. In turn, you can cut to desired lengths to create your own custom system. 820 Soaker Hose can be run in lengths of up to 250', but not to exceed 500' from one water supply. GPH is approx. 224 gallons per hour, per 100' at 25 psi, depending on inlet pressure, water hardness. Shorter lengths will have an increase in GPH. Use this size if your rows need to be between 150' - 250'. Green Stripe .820 Soaker Hose uses standard compression fittings. Hose should be used on flat surfaces not exceeding a 2' rise over 100'. A pressure regulator is a MUST since soaker hose is designed to work at low pressure. Some fitting sizes are marked on the tip of the fitting.
