Drop a plug into a hole that is too big and the roots sit in an air gap and stall; force it into one that is too small and you tear the new roots off. Matching hole size to plug size sounds trivial, but it is the difference between a batch that carries on growing without a check and one that sulks for a week.\u003c\/p\u003e\u003ch3\u003eHow to Use\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eSoak cubes in pH-adjusted solution until fully saturated, then let them drain.\u003c\/li\u003e\n\u003cli\u003eChoose the hole size that matches your rooting plug or smaller cube.\u003c\/li\u003e\n\u003cli\u003eDrop the plug in so its top is level with the cube surface.\u003c\/li\u003e\n\u003cli\u003eSit cubes in a tray to keep them upright and evenly watered.\u003c\/li\u003e\n\u003cli\u003eWater little and often, never letting the cube dry out completely.\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\u003eRockwool cubes and cube tray\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCube Sizes\u003c\/th\u003e\n\u003ctd\u003e3 inch, 4 inch and 150mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHole Options\u003c\/th\u003e\n\u003ctd\u003eSmall hole or large hole\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMaterial\u003c\/th\u003e\n\u003ctd\u003eCultilene rockwool\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eApplication\u003c\/th\u003e\n\u003ctd\u003eRooting cuttings, seedlings and growing on\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eAlso Available\u003c\/th\u003e\n\u003ctd\u003eSmall cube tray\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003c\/div\u003e","brand":"Cultiwool","offers":[{"title":"4\" Small Hole","offer_id":53446965821706,"sku":null,"price":0.49,"currency_code":"GBP","in_stock":true},{"title":"4\" Large Hole","offer_id":53446965854474,"sku":null,"price":0.45,"currency_code":"GBP","in_stock":true},{"title":"3\" Small Hole","offer_id":53446965887242,"sku":null,"price":0.34,"currency_code":"GBP","in_stock":true},{"title":"3\" Large Hole","offer_id":53446965920010,"sku":null,"price":0.34,"currency_code":"GBP","in_stock":true},{"title":"Small Cube Tray","offer_id":53446965952778,"sku":null,"price":11.49,"currency_code":"GBP","in_stock":true},{"title":"Huge 150mm Cube Large Hole","offer_id":53446965985546,"sku":null,"price":2.49,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0748\/7127\/5786\/files\/Cultiwool_SmallCube.jpg?v=1785325166","url":"https:\/\/hydrocropshop.co.uk\/products\/cultiwool-cubes","provider":"Hydro Crop Shop","version":"1.0","type":"link"}
