The original Hydroton brand expanded clay is a unique, lightweight expanded clay aggregate made in Germany. This natural clay is mined, formed into pellets, then kiln fired at high temperatures to cause the clay to expand into tough, lightweight balls. Clay naturally has balanced capillary action, with an ideal surface structure. Hydroton brand expanded clay is semi-porous and generally does not float like other products can. For best results, rinse all expanded clay before use. It is reusable as long as it is thoroughly cleaned between uses. 50 liter bags feature an easy pour spout. Size specification is 8-16 mm. Review: Truly a superior product - I had become interested in inorganic media for my orchids since a great deal of my struggle was staving off rot, and I purchased some from a local hydro shop. It was garbage! Hardly wicked moisture, severe layering; a 3 inch tall plastic pot was dessicatingly dry on top with the bottom being completely waterlogged. Needless to say it was bad for my babies, and they tolde very loud and clear. I decided to try again with a more expensive (per L) product and... I am shocked. It performs so much better the old media might as well have been rocks. Truly, quality is far superior to quantity in this regard. A 12-inch vase I was using as a guage managed to get water all the way to the top, no help at all, just pure capillary action. The old product managed about an inch and a half, and since I payed $10 for 10L I think the cheapness speaks for itself. Do yourself a favor and don't make the mistake made: when it comes to expanded clay, more expensive is so unbelievable worth it. Sadly, I do not know what the specific brand of the old stuff was, it was kept in a large unmarked bin at the store. Guess I won't be buying anymore mystery media. Review: Beautiful Hydration, work well - Like the size of pebbles. After opening the secured package, I immediately soak the hydration in water for 5 min. Then quickly rinsed for 3 times. The pebbles are now clean and beautiful. With those hydration pebbles, my watercress have been growing very well. ## Features - BAY HYDRO LLC Ships in 24 HOURS, Don't believe the Estimated Date, As we are "SUPER FAST" - The original Hydroton brand expanded clay is a unique, lightweight expanded clay - Clay naturally has balanced capillary action - This listing is for 4 Liters of Hydroton in bag.
