Using drip lines is an effective way of controlling the amount of water you feed into the soil for your crops. Too much or too little can give your plants problems and you need to monitor what they get at different times of the growing season. You also need to factor in the climate during the growing season and, depending on where you live, it can be uncertain to say the least! Using a 16mm to 16mm Threaded Tee for 8 Way Manifold (FT209) will let you connect this male/barbed tee to a threaded socket that you can use with an eight outlet manifold. It enables you to cover a wide area with drip lines if you have a large growing area and help you control how much water your crops get. Setting up drip lines with the manifold you need will make a real difference to your growing success.
