Sowing tiny seeds in neat rows can be a tedious process. Often you will oversow them then need to heavily thin things out later. This is wasteful and inefficient.
There are lots of commercial devices to help but they can be expensive and often don't work very well.
I came up with this after seeing a similer device in a catalog for $80 and thought I could make it cheaper.
You will need:
1) A Sonicare or other sonic type toothbrush (You may be able to use other types of electric toothbrushes I just happened to have a Sonicare)
2) A single slat from a vinyl mini blind
3) A rubber band
Step 1: The Parts
Cut the slat about 8 inches longer than your toothbrush.
Step 2: Using Your Device
The seed will march down the "V" like ants at a picnic.
Step 3: UPDATE-Adding a Bulk Hopper
Someone said that they would like the device to hold larger amounts of seed so they wouldn't have to reload as often.
After some pondering (and a raid on the junk drawer in the kitchen) I came up with this.
I got a small funnel, cut off the handle and taped it to a piece of mini blind slat.
You could use hot glue also.
I drilled a small hole, in this case 5/32", in the funnel to allow it to slip over the metal vibrating tip of the toothbrush.
A litle bend in the mini blind slat and a zip tie, done.
