In order for low temp of the fridge to work (stratification), it has to be combined with moisture. Sticking seeds in the fridge without it defeat the purpose. Seeds naturally wake from dormancy with a combination of cold and moisture in nature. Then sprout with warmer soil temp.
Some seeds, like tree seeds, have a double dormancy and require cold, warmth, cold, and warmth again, to sprout.
CAPTION. These are Aquilegia (Columbine) sprouting in a moist kitchen napkin prior to transferring to a seed flat. These were sown Feb 17, then in the fridge for 2 weeks. They germinated March 18 in room temp. Those that have no roots have swelled and ready to sprout.
There are some seeds that benefits from smoke. Here is an excellent seed data base with lots of information. Also sells seeds. Somewhere on this website smoke is mentioned. Just look around. It also mentions the G. acid.
