HYDROTON Clay Pebbles Original Growing Media CHOOSE YOUR LOT SIZE ABOVE 1/2 LITER AND UP! Expanded Clay Rocks for Hydroponic Aquaponic systems seedlings etc.. A very effective environmentally friendly mediumIf for any reason our customers are unsatisfied We Guarantee your money back.High Pore SpaceLarger aggregates like hydroton have much larger space between each pebble than perlite, sand, and other small particles. However, the biological surface area isn’t usually as high but the pore space is much higher.This means that larger pore spaces have a better flow of solution through the media even when biofilms from algae and microbes cover the surface of the media. The water drains very effectively as the hydroton rarely becomes clogged or blocked. This makes it a great choice for ebb-and-flow systems and aquaponic media bed systems.Air-Holding CapacityIn the air holding capacity, hydroton cannot compete with perlite. But hydroton has some air holding capacity and when it is combined with great percolation then it is difficult for problematic anaerobic zones to occur.Renewable and Environmental FriendlyHydroton is not made from much clay and the clay used is abundant, so most people consider it an environmentally friendly medium to use. Hydroton uses less amount of materials compared to other media which uses a greater amount of earth’s supply.Moreover, you can also use these hydroton balls to make lightweight concrete blocks which can be later used in construction.ReusableAnother great benefit of hydroton is that it can be used again and again. All you need to do is rinse any built up silt or organic matter from it before reusing it.Easy to Plant and HarvestHydroton is a loose media which makes it easy to transplant and pull plants out of after harvesting.Good for MicrobesGrow stones are great for growing plants but are not great for colonizing microbes. As you may already know that BSA provides habitat for the microbes which make nutrients from organic sources like fish feed available to plants. Less BSA means fewer microbes, this also means a less responsive and less stable systemIf for any reason our customers are unsatisfied We Guarantee your money back.We pack carefully and ship same day when possible.
