In non-pressure compensating systems, spray stakes at the beginning of the line experience higher pressure and deliver more water than those at the end, leading to uneven watering. As a result, plants at the front receive excess water while those at the end may not get enough. Netafim Spray Stakes are specifically designed to match the shape of the pot, delivering a precise amount of water and fertilizer directly to the plant. Their spray pattern ensures even soil surface wetting, maximizing water retention and promoting uniform release of liquid or timed-release fertilizers. By eliminating overspray and runoff, these stakes help conserve water, energy, and fertilizer costs. Engineered for simplicity and reliability, Netafim Spray Stakes feature a rugged and reliable one-piece construction, making them super simple to clean. They also include a simple close-off feature for easy control. These stakes are also considered 'BMP' Friendly. Pressure compensating models include a check valve for improved control of water and fertilizers.
