The seeds from you brother,@Sebring, were much easier than the Headbands or my really old seeds. They they were likely years older.
The 1 with the longest tap root has shed here helmet and the rounded leave were starting to unfurl. I let the other go an extra day. Its tap root only grew about .020". I put it in coco early yesterday afternoon. I used new CocoGro to fill the 4" square pot. I made a hole in the center approx. 1" dia x .75" deep, filled it with the recovered CocoGro because it is finer. Watered with: 8oz seed solution, .5 tsp molasses, 2 drops Superthrive, 1.0 oz sprouted seed tea (made from .25 cup malted barley and .5 cup RO water). I put a humidity cover over it made from the top of a clear 2L soda bottle and set the temp on my seedling mats up to 88°.
Fingers crossed about seeing some difference tomorrow.
Your welcome. The next time I try the very old seeds will be in at least 2 weeks. when I do, I’ll be using the germination bomb documented in this post from @MadScientist: Germinating old Seeds - #44 by MadScientist
Farther down in the topic is where I started my seed trials, documenting as I go.
Thanks for taking an interest
