{"product_id":"clay-pebbles-8-16-mm-10l","title":"Clay Pebbles (LECA) 8\/16 mm 10L","description":"\u003cp\u003eThe classic pebble size, and the one most people picture when they think clay pebbles. These are our own Grow Pro clay pebbles (LECA) in the standard 8 to 16 mm size, bagged by us in a handy 10L size. Most shops only sell the big 50L bag, so if you just need some for a few pots, this is your bag.\u003c\/p\u003e\n\u003cp\u003eClay pebbles are little balls of clay baked until they puff up hard and full of tiny air pockets. They do not break down, they do not turn to mush, and you can rinse them off and use them again for years. The 8 to 16 mm size is the all rounder: small enough for most pots, big enough to keep the air moving around the roots.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat it is good for:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSemi hydro and passive hydro setups, the size most guides are written for\u003c\/li\u003e\n\u003cli\u003eA drainage layer at the bottom of pots\u003c\/li\u003e\n\u003cli\u003eChunky potting mixes for aroids and other air lovers\u003c\/li\u003e\n\u003cli\u003eOrchids and clear pots where you want to see the roots\u003c\/li\u003e\n\u003cli\u003eA clean top dressing that keeps soil from splashing and slows down fungus gnats\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eHow I use it:\u003c\/strong\u003e give them a good rinse before the first use, there is always some clay dust in the bag and that is normal. For semi hydro, soak them for a few hours after rinsing, then keep the water level below the roots. In a mix, I use them as one part of the blend with bark and perlite.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eGood to know:\u003c\/strong\u003e pebbles hold almost no water themselves and have no food in them, they are pure structure and air. In semi hydro your plant still needs hydroponic food in the water. Reuse them almost forever, just rinse or soak between plants.\u003c\/p\u003e\n\u003cp\u003eBagged and sealed by Grow Pro at Booth 801, Oshawa Markets. Not sure which size pebble your setup wants?
