Honestly, that was a stop gap until we could start doing other things, which hasn't happened yet because the flora and fauna can be so different because of the radiation. It's been relegated, a bit, to the backburner until we have more resources.
Although I'm pretty certain I saw a good patch of camomile the other day. I'm working on getting samples in of it, so that we can get a good patch growing. I think a lot of us would benefit from a bit of camomile tea.
