You may have more luck than I did -- while the Geek Valley 4.0 Garden of Eatin' was ridiculously prolific, it was just too warm in the Valley of the Damned to successfully grow cold-season crops like that... they gave forth a tiny bit of foliage, then bolted.

Also, I inherited some mesclun, and I have to be honest here -- all those fancy things that go in "mesclun"? Yuppie weeds that taste terrible. I like LETTUCE -- Bibb, romaine, butter, even, yes, iceberg (with some lardons and caramelised onions and homemade buttermilk-bleu cheese dressing, mmmmmmm...).
