Would it be too late to take the seeds out, dry them, do the matchbox/sandpaper thing, and then retry?
^If it is... I might just try to cut 'em open.
Or should I count my losses and get another pack of beans? :(
Well, don’t use paper plates if not using the heat mat. Sounds to me your method was fine, before adding the heat mat. 95% + strike rate on varying genetic lines is more than acceptable. Those results should bring a smile to your face
— especially if they’re not your own creations.
It’s worth a try. Give them a week and if not successful, grab another pack. That is, if they’re readily available; and you think the heat mat was most likely the reason you had poor success - if nothing else, popping a new pack with your old proven method (without the heat mat) will tell you where the trouble was. Or might’ve been. You can eliminate possibilities.
And while I never have been as patient as Smoggy, I have had seed pop two + weeks out.
