Who knew? I'm so fascinated (in a sincere way) how things we take for granted have such details to them. I remember both of my grandmothers having gardens, and growing most of their own vegetables, but other than smearing cow shit in between the rows, it was plant seeds, water, and wait. Sure, some of the vegetables looked like hell (and are thus, for Chino's purposes, unsellable) but they always tasted fresh.
I know it drives some people crazy, but I love that process of trouble shooting, and the satisfaction and pride from dialing it in the right way when you're done.
I'm impressed. Chino, and wish you the best of luck. If you get into any grocery stores, let me know; I'm not down the street from you, but I do try to eat salads a couple times a week, so it might be worth it to drive for a quality product. Nothing worse than going for a head and finding the center all brown and soft. What type of lettuce? Iceberg? Romaine? Something else?
