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.

Using HydroCorn:

Gold Label HydroCorn Clay Pebbles usually need to be washed prior to being used as they tend to have clay-dust on them due to rubbing together during transportation. For the very best results, wash and soak in pH adjusted water over a period of 3-5 days, replacing the pH'ed water daily. This will produce a medium that does not increase the CF of your nutrient solution and has minimal impact on pH. When they have been cleaned they can be put into ebb and flow (flood and drain) systems or into pots for a dripper-system and your plants put straight into them. After harvest, old roots can be removed manually before re-use. Soaking the pebbles in a quality enzyme product for a few days will also help break down the old roots. By doing this, clay pebbles can be re-used several times. However, after a few uses, the HydroCorn clay pebbles tend to lose their rough, porous surface and will need to be replaced to maintain your grow-room efficiency. Gold Label HydroCorn Clay Pebbles can be mixed into soils to improve drainage or used to top-dress soil-containers to reduce water evaporation.
