A strainer or filter may be needed to keep holes from plugging. Soaker hoses can be used in conjunction with an irrigation controller. An anti-syphon valve may be required if used with a domestic water supply. Holes can be placed for exact delivery. Less weeds between rows.
Holes can plug.
If holes plug, hose can be damaged on high pressure system. This may be the ultimate water conservation method. Pipes or tubing are run down each row with emitters placed at each plant. Emitters release water very slowly, gradually providing water to the root zone, maximizing water uptake by plants. A filter and pressure regulator are required.
