Here’s a tip I haven’t tried yet but comes highly recommended, it’s just a particular way to do the paper towel and Ziploc tek that makes it easier for old seeds to drop a first root out by assisting it with gravity and the natural urge of a seed to orient itself downwards toward the magnetic core of the earth. From what I understand, when seeds are planted upside down and have to turn their shoot around, they are not necessarily just moving away from light, they’re also orienting themselves using gravity and the Earth’s magnetic field.
Another good hack/tek for seed starting as well as a lot of other organic garden things is getting a thrift store yogurt maker or two for $5-10. A complete unit will come with a (usually) clear dome lid and individual cups for each slot, with lids and probably extras. Yogurt makers are specced to keep the inoculated milk at 108-112F (ideally) so it’s a little hot, but by either leaving the lid off and using spacers under the cups, or the addition of a resistor dial plugged between it and the wall you can dial that down to whatever nice warm temp you want. It’s a DIY germination machine! Hope MM is okay out there we haven’t seen him in a while here:
