Seeds come in different shapes, weights and sizes and most seeds must be planted at a specific depth to meet individual requirements for optimal germination and growth. So it is important to know the unique properties of the seed you use in your nursery to determine the optimum hole size and needle type of the Williames Seed Drum you need.

The Williames Seeder places the seed in the tray cell in a precisely programmed operation. The Williames Seed Drum has exactly calibrated needles that deliver the single seed into a single cell in the tray at very high speed—so accuracy is absolutely vital.

Multi-stage and multi-direction seed singulation is achieved using air brushes in conjunction with the needles that accurately position the seed in each tray cell. Williames Seed Drums can be tailored for unusual seed varieties and different combinations of seeds—to meet your needs.
