Market Farming

[Janet Bachmann <janetb AT ncat.org>]

Somewhere I saw a construction plan for making a box-shaped, vacuum 
powered seeder.  It included a plate with holes that corresponded to 
cells in flats, and sized so that seeds would not pass through the 
holes.  When a vacuum was applied to one side of the plate, a seed would 
be held to each hole.  The plate would then be held over the flat, 
vacuum shut off, and the seeds would fall into place.  A number of 
dealers have vacuum seeders for sale, but I would like to find the 
make-it-yourself plan.
