1. Dry strip the room — old soil out, leaves bagged
  2. Wash every surface — bleach or hydrogen peroxide solution
  3. Replace HEPA / carbon filters
  4. Disinfect pruning shears, scissors, ties — they spread disease
  5. Inspect lights and timers — pre-failures kill the next cycle
  6. Log the harvest weight, smoke notes, and any defects
  7. Sample-jar 1–2 buds with the strain name + harvest date for long-term reference
