Thanks! The stuff I read suggested if the seeds were really old then they might not have proper sugar stores of their own, but youāre right its mostly going to be microbe fuel, which is super risky early on. Iāll try the next batch without any sugars and with the higher % hydrogen peroxide you mentioned.
I think temps were my main failing point. I do usually just germinate seeds in the house temps, but after a bit more reading its clear those really arenāt ideal. and in fact it seems mid to upper 70s would be better. These seeds are from outdoor cannabis too, used to northern california. My dad & the neighbors would start them indoors, but Iām sure it was somewhere warm in the house. (Wood stove heating back then. ) Iāve got a tub set up and temps are up in the mid 70ās now.
Some tails popped out from batch #2 and Iāve just moved all the seeds from the soak into paper towels in a little glass tupperware. The towels just have filtered water mixed with a little tiny bit of the fulvic acid stuff.
Iām going to have to set up some heated seedling trays in my greenhouse too, because assuming I can get some past the tail stage I bet these baby plants wonāt put up with cold nights like my others do. What a PITA
