40+ year old seed (unknown strain)

Greetings! I recently helped my father move, and in the attic we found a bunch of stuff from the past. Among these things were a glass container with cannabis seeds. He told me that they were from a guy who supplied their village with (shitty) pot when he was a teenager, and they were at least 40 years old. I took a few seeds and didn't expect them to even germinate. I sanded the seed slightly and soaked it for 15 hours in lukewarm tap water (pH 7.5) and put it in a paper towel and in a ziploc bag at 28th of november 2019. It's been almost 2 months but it finally happened -- a tap root has emerged! January 22: Seed successfully sprouted into a seedling. Transplanted the jiffy into a 1L container with moist peat moss and covered it with a plastic cup. Let's call it Day One and see where it goes! Day 2: Got home from work and found a yellowing and halfway wilted seedling. I removed the jiffy from the peat moss and the seedling from the jiffy, cleansed with tap water and put it back into an almost dry jiffy. Crossing my fingers! Day 3: Plant CPR seems to have worked. Seedling is getting its green color back and no longer fighting just to stay upright. Day 4: Doing perfectly well again. Day 5: Watering 10ml every 6 hours. Day 6: Another attempt at transplanting into an actual pot. Let's hope it doesn't yellow up like the last time :) Day 7: It survived the night in its new home. Looks like we have a working setup for the next few weeks.
