I had an issue popping blueberry hashplant, only 2 of 6 seeds popped. BUT at the same time I had an issue with 2 other strains from 2 different breeders so obviously the issues were MY fault. Had that been my first and only experience with Bodhi, and the only seeds I popped, I might have jumped to the conclusion that the seeds were at fault. I suspect something as simple as a cold breeze was the issue in my case as it was during a winter cold spell. Never had an issue before or since so sometimes it's just a freak thing.
temps are a HUGE influence on germination.
what I do is this, and granted it's a lil hard to replicate but this technique gets me 95% germination, and usually within 12 hrs, that's right. 12 hrs.
I've had Bodhi seeds that "oyster" in 6 hrs.
Get a shot glass of water, get it to lukewarm temps, to the point where you almost
can't feel it when you put your finger in it, approx. 75 to 80 degrees is typical skin temp on the fingers.
Pop the seeds in, at first they'll float, in about 2 hrs they'll be able to sink if you swirl it around a lil.
What I do is use an old onkyo stereo receiver, I turn it on, put the shot glass on top and it stays the right temp, one could use a seedmat for this as well, but it's CRUCIAL the temps are consistent.
plant in whatever media you want after they oyster, do NOT wait long enough to see the root tail, you want to plant when they "oyster"
if the root tail popped out, you waited too long.
haven't had a seed take longer than 2 days with this method.
very, very little issues with seedlings dying also.
That's why you want to make sure to plant them early.
Plant them no deeper than 1.5 cm
