Because the fibres hold water while the open structure between them holds air, you get a root zone that stays wet without going anaerobic — the balance that drives fast establishment and vigorous growth. It is filled straight into pots, containers or net pots in the same way you would use clay pebbles or coco, which makes it an easy swap into an existing setup.

Too dense and it waterlogs; too open and it dries out between feeds. Mapito sits in the middle: the rockwool fibre itself carries the water, while the gaps between flakes stay open to air. That is why plants tend to establish quickly in it and keep feeding steadily right through the cycle.\u003c\/p\u003e\u003ch3\u003eHow to Use\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eFill pots, containers or net pots with Mapito to your usual depth.\u003c\/li\u003e\n\u003cli\u003ePre-wet thoroughly with pH-adjusted nutrient solution before planting.\u003c\/li\u003e\n\u003cli\u003eTransplant rooted cuttings or blocks straight into the medium.\u003c\/li\u003e\n\u003cli\u003eFeed little and often — several short irrigations beat one long soak.\u003c\/li\u003e\n\u003cli\u003eCheck runoff to keep the medium moist rather than saturated.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cdiv class=\"hcs-specs\"\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eProduct Type\u003c\/th\u003e\n\u003ctd\u003eLoose rockwool growing substrate\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eVolume\u003c\/th\u003e\n\u003ctd\u003e80 litre bag\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMaterial\u003c\/th\u003e\n\u003ctd\u003eCultilene rockwool fibre\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eApplication\u003c\/th\u003e\n\u003ctd\u003eHydroponic systems, pots and containers\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eBest Suited To\u003c\/th\u003e\n\u003ctd\u003eDrip irrigation setups\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003c\/div\u003e","brand":"Cultiwool","offers":[{"title":"Default Title","offer_id":53446965723402,"sku":null,"price":26.49,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0748\/7127\/5786\/files\/Cultiwool-Mapito80LitreBag.webp?v=1785315597","url":"https:\/\/hydrocropshop.co.uk\/products\/cultiwool-mapito-80-litre","provider":"Hydro Crop Shop","version":"1.0","type":"link"}
