I see that you are in San Antonio. That's real close to me. Do you do your water garden outside? If so, does it help keep your greens from bolting? I've had success with basil and mint (and eggplant/okra/tomatoes/sqaush) here, but even in winter my bok choys bolted almost immediately. I can do...
Can you post a picture of that? I've been thinking of doing something similar, but when I tried before, my chickens busted in and got all my seedlings and young plants (I don't even think they ate them, they just left chicken-sized craters everywhere). I was too upset to try again.
