I was at a show once and the cucumbers got very shriveled, brownish and had shrunken, so I squirted some water and forgot about them. Ten minuted later, they were nice and plump and greenish.
They only have tiny clinging roots, so mounting them would be good. But they do need moisture and they will let you know it.

The best way to grow them is mounted. I guess in the photo they are in a 3" clay pot. But that's only because we planted them from flask into CP's. From there they will be mounted.
