Very cool.
Outside of the 'hard freeze' period, I recommend growing mustard. Eat the fresh greens. Don't get mustard bred for human consumption, get the cover crop stuff you are supposed to till under... it's better.
These were black oysters. Took less than a couple of weeks, just sitting on a shelf indoors. Misted with water a couple of times a day, that's it.
These kits are prepped to be easy but even with that expectation I was surprised by how well and fast they grew.
I'd like to try an outdoor setup in a log this year. This newbie success was good encouragement.
I cook it like collard greens - smoked pork hock liquid (if not with some of the pork), onions, a touch of vinegar, served with hot sauce.
Since I built my new house I haven't started a garden again, but once this summer is done (I'm in the Southern hemisphere) I'll at least make some space for these.
