soaking seeds in colchicine is not to produce a hermi mother thats giberelic acid (not sure on spelling) and another acid to reverse it.

Colchicine is used to cause polyploidy which in theory is where we get high thc strains from and is a poison to the seed and everything, so its very hard to get them to germ and tens of thousands of seeds are needed.

disclaimer: i have not worked with it, just have done research in my many years of growing.
