I’ve been working with some old poorly germinating seeds trying lots of different stuff. The best results so far have been with first, scuffing the seeds on sand paper, then put them inside a fresh aloe slice 12 hours or so, next they go into tap water to soak for another 12 hours or so, then any that have opened go into root riot cubes, if not opened they go into a paper towel and on to my heat sink on top of one of my lights where the temp stays between 75 and 85f until they open then into root riot cubes.
