Decanter?

You can use coffee filter paper or a chemistry paper filter (much better but expensive & hard to find). You wrap your seeds into a tiny bad of a paper filter; deep into bleach solution (10% Clorox for 15 minutes) then deep 3 times into sterile and distilled water; then sow. It's easy to handle that way: no filter, less contaminate, no special equipment. I have few bags of Phal dry seeds; PM me if you want to exchange?
