It depends on how much growing space you have to determine exactly what your irrigation needs are. Both overwatering and underwatering plants are liable to cause growth problems so setting up a system that suits what you need is an important part of the way you set things up. Using drip lines can deliver exactly the amount of water required and will penetrate the ground over a period of time. Using a hose to water and spray can be effective but not so much if there has been an unusually hot and dry spell of weather. The 4 Way Outlet Manifold (DR131) can provide access for several supply tube outlets, into 4 x 4mm outlets. It comes complete with an insert nipple.
