Gold Label HydroCorn clay pebbles are probably the most effective type of clay pebble for hydroponic use. HydroCorn pebbles have a much more uneven shape than the traditional clay ball and are shaped a bit like popcorn. Gold Label HydroCorn is RHP certified which means that it is a consistent and high-quality grow medium that’s completely crop-safe.
