growing water plants

People often forget that water plants are so easy to grow. Easier than plants in pots.

All you need is a few ceramic or metal containers. Now is the season to grow KangKong, it is cheap at Asian Grocery stores and all we do is throw it into water with a handful of soil.
Even the snails can't touch it!! it is wonderful in stir-fry dishes.
