Greater Surface Area & Better Water Holding Properties for Rapid Growth and BIGGER PLANTS
 
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.
 
How HydroCorn Works
 
Gold Label HydroCorn clay pebbles are irregular-shaped pebbles of expanded clay which resemble popcorn. They have an uneven and coarse surface with lots of pores, giving them a huge surface area which allows them to hold lots of water. Because the clay pebbles are hard they do not compact down and they retain air-spaces between them providing lots of oxygen for roots. The spaces between them also mean that HydroCorn drains very freely, avoiding water-logging. HydroCorn can be added to soils, coco and soilless mixes to improve drainage or can be used to top-dress pots containing other grow-mediums to reduce water evaporation.
