Wash return refers to how much usable hash is collected from fresh frozen material.

As a general rule:

• 1–2% = below average
• 2–3% = solid washer
• 3–4% = excellent washer
• 4%+ = elite hash producer

While environment, harvest timing, and washing technique all play important roles, genetics are often the single biggest factor.
