Hi, There's been chat here in the past about putting seeds in toilet cisterns so that repeated changes of water wash out any chemicals that inhibit germination. It also chimes with the thread about floating seeds to germinate them. Surprising no one has made a seed washing machine. Probably some answers in: SEED GERMINATION THEORY AND PRACTICE; by Professor Norman C. Deno.

Maybe a dripping tap/burette would produce a similar effect. -- David Pilling http://www.davidpilling.com/ _______________________________________________ pbs mailing list pbs@lists.pacificbulbsociety.net http://lists.pacificbulbsociety.net/cgi-bin/…
