R-Wide or Mark II?
It comes down to three things: your water pressure, how much flow your source delivers, and where you grow. Parts come in a version for each tubing and don't cross over.

Time how long your hose takes to fill a 5-gallon bucket. The Water Supply Check turns that into a recommendation; the System Planner sizes your tubing and fittings.
