24 hour water soak or wet paper towel method?
How do you pH ro, lol.
Personally I soak my seeds until they sink and then I plant them in clean potting media (pref a seedling mix). I use this method when I’m not too worried about getting 100% germ rates.
Papertowel method works well for me too but I don’t like to disturb the seed once the root has sprouted. It is a cost-effective way to get good germination rates but requires a steady hand so as not to damage the tap root.
The way I get the most success with germination is Rapid Rooter plugs. It costs more than the other methods but imo is easier. I soak plugs in mycos/lacto/water and squeeze them out before use (roots need air). I use the trick where you skewer the bottom of the rapid rooter plug with a match stick and plant 2 seed lengths deep. This is supposed to ensure good contact between the plug and the seed.
I don’t think you have to, but I like to soak the seeds for 4-8 hours before I plant. 4-8 hours is the average time my seeds take to sink.
I soak my seeds in a Korean Natural Farming solution called S.E.S.(seed treatment solution) until they crack. Then into a moist paper towel. I use a proofing box to keep the temperature at 82 the whole time. Works like a charm.
I like the wet paper towel on a plate-method, especially for older seeds, they can sprout easier and I can see if and when they do so. It's best to get them all the way sprouted/out of the shell, if possible, that is one down side to the paper towel method; sometimes the shell gets stuck on the sprout, when sprouting in dirt and sowing with the pointy tip upwards the resistance of the soil will drag the shell easier off.
It's also nice to sprout them directly in the medium, it also makes for fewer mutants because of lesser handling of delicate roots.
