Generally, large grain seeds should be fine sand or sandy loam, and medium and small seeds can be used with gauze, filter paper, paper and absorbent cotton.
Put a small paper bag containing the measured sample into a small beaker, inject 0.1% to 0.5% potassium permanganate solution, and immerse the seeds(gallon pot). After 20 minutes, take out the cloth bag and drain it.
