These are pretty old. A 250ml LC jar was inoculated with a couple milliliters of Master syringe. 2 days to settle into the jar and then kept at about 40°. I've noticed only that their height is about 50% of the first time I used them. I assume that this is possibly the strain getting tired but I don't know enough to say that yet. All the same the equally old Mound 4 did just about the same as it did. I'm starting to see the same strains performing different in different grow-vessels and I'm starting to see Variegated Cordys do some very cool stuff after a year. My point is only that I'm starting to log this stuff down to weighing everything down to the cake itself after harvest to see if I can repeat what's already happened as well as possibly figure out if I can rely on my own notes to know which can take storage, best vessel and what yields the best. I hope to make my own "expiration dates" from this and just know what is worth the fridge space and how far I can take various strains. Also switching to oats has been pretty good.
