How many times can the grow bags be reused, and what is the cost per use?

When structurally sound, HOKBG heavy-duty PP grow bags can be reused for years; outdoor service life is about 3–10 years (shorter in high-UV regions, varying by latitude). Amortized over ~5 years at 1–2 cycles/year, the cost per use is far below disposable plastic pots. Before reuse, inspect sidewalls, bottom, seams, and handles; clean, dry, and store away from direct sun to extend life.
