Re: [IGSROBIN] Germination information request and new member biography
I can't speak to the parentage issue, but I have some fairly standardized
germination techniques that seem to work with a variety of gers and pels.
I use a mixture of 50% medium grain vermiculite, 50% sharp sand by volume
(one cup of each, for example.) I moisten it, and then nuke in on high
until steaming. Let cool, moisten thoroughly with 10% strength liquid
fertilizer, drain. Be sure to add the fertilizer solution after nuking-if
you add it before and the temp gets above 160 F it will produce ammonia
compounds that are harmful to seedlings.
Lay seeds on surface, cover with thin layer of nuked sand. cover flat until
seedlings emerge (3 to 12 days ususally). If your germinating area cools
off at night, sit the flat on a heating pad set to low.
For really stubborn seeds, or older seeds, I use a one hour soak in a 200
ppm solution of gibberellic acid in distilled water before transferring to
the germinating medium. If they won't germinate after that, they won't
Hope this is helpful.
