Thanks guys. You're all awesome. I've just been stressed about financial stuff, but in the big picture of what really matters, that's all just passing waves. Black Stone 1 is growing on like nothing happened and looks and smells amazing (not flowering smell of course, but a deep, rich plant aroma unlike anything else.) Black Stone 2.1 damped off like 2.0, but I still have four of those seeds left, and I'm not giving up. This time I'm not going to mist it until it gets well established, and I'm going start it in a cup so I can more easily tell how much water it needs. Also, before I plant it into the growing medium, I'm going to sprinkle some of the Great White into the hole so the root gets inoculated as soon as possible. I'm feeling hopeful about this one. I've already learned so much from my mistakes that I have a pretty good idea about how to make things go more smoothly.
I have to say, compared to plants, growing mushrooms was a cakewalk. These plants are a bit more needy, it seems. Of course my problem so far has been attempting to nurture them too much. Good thing I got all this fungus and bacteria to help toughen them up. Really though, it seems that sort of symbiotic relationship is something plants should have, since almost all plants in nature grow in soil rich with microbial and fungal life. Anyway, the growing continues, and I have 9 more Portal seeds left, so it's not stopping any time soon.
