Fertilizer N-P-K vs. Garden Hoses
Comparing 2 standards across 15 specifications. 15 key differences identified.
Comparing:
Fertilizer N-P-K
Garden Hoses
Fertilizer labels display three numbers representing percentage by weight of Nitrogen (N) for foliage growth, available Phosphate (P2O5) for root development, and soluble Potash (K2O) for drought and cold hardiness.
Residential garden hoses standardize at 5/8-inch (15.9 mm) inside diameter delivering 10–15 GPM, fitted with 3/4"-11.5 NH Garden Hose Threads (GHT). Lightweight hoses measure 1/2-inch (6–8 GPM), while commercial high-flow hoses measure 3/4-inch (18–22+ GPM).
