This machine is for the Commercial or larger growers. Or plug producers. Typical sowing rates for a plug tray would be around 700 trays per hour, or 300,000 seeds per hour. Direct sowing into bedding plant packs is also possible at even higher rates. Variable speed is a standard feature. One of the major advantages of the Hamilton Drum Seeder is that it will sow into virtually any plug tray, seed flat or bedding plant container on the market today. With the additional new MEGA seeder kit for larger seeds, we can seed almost any seed using this seeder.
