Gold Label Hydro Clay Pebbles are manufactured using a mix of the best quality pure clay and are baked in an open furnace using high grade clean fuels, guaranteeing absence of heavy metals or other contaminates. Gold Label Hydro Korrels proudly carries the RHP for horticulture quality certificate.
Gold Label Hydro Korrels is the inert hydroponics substrate of choice for professionals. The 8-16mm size provides stability and the unique uneven shape of the pebble is an ideal surface for roots to cling and promotes beneficial bacteria. The porous structure has a high water capacity and is suitable for both ebb/flow and top irrigation systems. Will not float!
Potting media for Orchids – Used alone or in combination with perlite, coconut husk chips, bark, charcoal or other orchid media, Hydro Korrels’ porous structure can provide excellent aeration around the roots while its ability to act as a water reservoir will be appreciated by your orchids when water is needed. We prefer this clay pebble over the round-shaped Hydroton. Because of its uneven sizes and shapes, Hydrokorrel clay pebbles fill in better around the orchid roots thus providing better stability in holding the roots in place while the plant is getting re-established.
Hydroponic/Hydroculture media – The capilliarity and the structure of the clay pebbles ensures good root aeration and prevents rotting, excess acidity and soil pests.
