Slide Hammer Seeder
Here are some links to show how to build and use a slide hammer seeder for small seeds. I thought this might be a good labor saving device so I built one for a friend who grows a 5 acre market garden. She tested it out and said that it works very well. I'm planning to build another one for myself for amaranth and quinoa planting. It should save me a lot of backaches.
Attached is a photo of me holding the one I built for my friend.
