Propagation: Can you start seeds in sand?, 1 by jkehl

My daughter's science experiment is in the picture below. She is testing germinating Pea seeds in a variety of mediums. Left to right she is using peat moss, pea gravel, MG potting mix, Sand, Georgia Clay and Water. It's somewhat hard to tell from the picture but the plants in the sand are the tallest and most vigorous followed closely by the MG potting mix.

The key is though she waters each plant a consistent amount (she uses a plastic measuring syringe) every day. So sand works good as long as you keep watering.

BTW notice that the only unsuccessful germination was the clay she dug from the back yard. It has weeds sprouted but no peas. The water germinated them but then they rotted and died.
