Shum whats ya temps i put mine at 27.5c untill there out and well then i continue as i would keeping it aroun 25c i also keep seeds in the fridge in dry container the change in temp and moisture makes the seed pop.
I stopped soaking mine waiting for it to crack cause i found when doing 100 baf seed this cracking didnt seem to help just my observation i know others have great sucess with it.
I just pop into soil at 27.5 (+/-.5c)
And about 70% hum untill they pop i wanna get just ir light to help even more.
I know some people use aloe juice when soaking for an extra boost
