HA! Another good reason to go to pet shops
I bought a Little Dripper on sale, thinking it would be good for my niece's salamander. Wrong. So I put it away. Then I got some cuttings and stuck them in new soil outside in the shade, filled it up, and set it to drip very slowly over the ground by them.
They are looking GOOD! I think I could duplicate the effect with a milk bottle that has a hole punched in the bottom (leaving the lid on.) I had another pot of cuttings and no Little Dripper for them; alas they are not faring as well.
