Just to share a mistake I made this past week chitting pea seeds.
My usual routine is to soak them in a plastic container with a lid until they start to swell, then drain them.
They get a fresh water rinse daily after that, this usually works well for me.
This year, I thought I'd do something clever (always a danger sign). I had removed and potted up a few seeds that were growing well, nothing unusual there. BUT... I had a container of weak liquid plant food, meant for house plants. I thought, why not add a few drops to my next seed rinse, maybe it will boost the growth a bit? Big mistake. I don't know if there was bacteria in with the fertilizer, or the fertilizer threw the plant (seed) metabolism off, but none of the remaining seed continued to grow. the remainders rotted, even the ones that had started to grow a root.
Lesson learned, from here on when chitting seed, I will rinse with plain water only.
