Grow!t medium clay pebbles - gallon

Hydrofarm Grow!t clay pebbles (also sometimes called Aliflor, Leca or Hydroton) are little light weight expanded clay balls that can be used alone to grow orchids which appreciate extreme drainage, or can be added to any orchid mix for added drainage and moisture retention. They are also great for hydroponic growing. Since they are made of clay, they do not break down! The little balls have a rough surface and are irregular in shape and measure about 1/2" to 3/4".. some are glommed together so a bit larger as well.
