{"product_id":"med-tek-super-silica","title":"Med-Tek Super Silica","description":"\u003cp\u003eMed-Tek Super Silica is a concentrated liquid silica additive for your nutrient solution, and its job is to give your roots plant available silicon (PAS). Silicon is the raw material a plant uses to build stronger cell structure, and that's where the resilience starts! Its dose never changes as the plants move from the growth stage into flower, so a single bottle covers the whole crop cycle.\u003c\/p\u003e\u003cp\u003eSilicon isn't one of the classic macro or micro nutrients. Even so, many plants take it up from the root zone and lay it down in and around their cell walls. Once it's there it stiffens stems and leaves, and a plant built that way holds up better under stress. Super Silica also carries potassium alongside its silicon dioxide.\u003c\/p\u003e\u003cp\u003eNot all of the silicon in a bottle is silicon a plant can use, and the usable share is what counts. Med-Tek report exactly that share for Super Silica: its plant available silicon is determined with the 5-day method approved by the American Association of Plant Food Control Officials (AAPFCO), not inferred from total silica alone. With a specific gravity of 1.6 it's a dense concentrate, which is why only a little of it goes into each litre of solution.\u003c\/p\u003e\u003cp\u003eMed-Tek describe Super Silica as an agricultural grade product made to increase plant resilience and yield, and they link its stronger structure to a broad set of outcomes: improved resistance to disease, airborne fungi, waterborne pathogens and pests, better tolerance of drought, salt and general stress, and increased yield and quality, including higher essential oil production in aromatic crops.\u003c\/p\u003e\u003cp\u003eThere's a reason the Directions set a mixing order for Super Silica. Silicon paired with potassium in a liquid concentrate is strongly alkaline. If the silica meets concentrated nutrients before it has been diluted and pH-corrected, it can come out of solution as a solid that the roots can't take up. Because its rate stays the same all the way through, it fits easily as the standing first step in every fresh reservoir mix.\u003c\/p\u003e","brand":"MED-TEK","offers":[{"title":"1 L","offer_id":67551606898846,"sku":"PLACEHOLDER910182","price":59.99,"currency_code":"AUD","in_stock":false},{"title":"5 L","offer_id":67551606931614,"sku":"PLACEHOLDER910183","price":239.99,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0709\/5261\/6094\/files\/Med-Tek_Super_Silica_1L.png?v=1792939119","url":"https:\/\/www.hydrooasis.com.au\/products\/med-tek-super-silica","provider":"Hydro Oasis","version":"1.0","type":"link"}
