The one-handed seed planter will be a row of plastic cones that create 1 inch deep holes and deposit seeds in them as it is pulled out. This could make planting a gardens worth of seeds much less time consuming than before. The one-handed seed planter would be made of a strong plastic that could push through compacted dirt and withstand multiple washings.
As you can see, the hard pointed ends of the cones are pushed into the dirt at an equal distance apart from each other
The cones can be filled with the desired amount of seeds and the amount released in each hole could also be controlled
