I elected to plant the seedlings in coir-filled pots, and put those directly into the growbed. I figure that way they get watered and fed regularly. When they get bigger I'll take them out of their pots and put them directly into the clay.
Armenian Cucumber (yes, this one's going to get ridiculously big. I'll either tie it to the roofbeam or enclose it in a tomato frame)
On the fish front... I'm pretty worried. Since I've got the water flowing through the system, it's one huge evaporative cooler. And of course that happens just as our weather goes to hell (for CA... I know it's nothing compared to the rest of the country, but I'm set up for CA weather). And the aquarium heater just isn't keeping up with it. So now the fish aren't eating. And since it's dark in the tank, I can't even see in well enough to be sure they're alive. But if they are, they won't be long if I can't get some food into them. So I'll stop at the fish store today and see if I can get a better heater. I'm also considering turning the system off at night. Maybe 8 hours of still water with the heater going will warm it enough.
So the plants are thrilled, the fish may be dead, and I'll learn more this weekend. :-D
