Concentrated fertiliser use over a full grow cycle inevitably leaves residue behind, and left unaddressed that build-up compromises how well roots can take up water and nutrition even when the feed itself is correct.\u003c\/p\u003e\u003cp\u003eIts active ingredient is \u003cstrong\u003esaponin\u003c\/strong\u003e, a natural extract of the yucca plant, which works by encouraging water movement through soil and soilless media and reducing the surface tension that otherwise limits moisture and nutrient absorption at the root.

FoxFarm schedule three separate flushes across a 12-week soil run, not just one at the end. Maintain a pH of 5.6 to 6.8, never mix pure concentrates together, and always add water first. On coco-based media, flush every two weeks during flowering. Check pH and EC after mixing.\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Fox Farm","offers":[{"title":"1L","offer_id":53500720906506,"sku":"FXF-SH-1L","price":24.9,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0748\/7127\/5786\/files\/FoxFarmSledgehammer.jpg?v=1786377635","url":"https:\/\/hydrocropshop.co.uk\/products\/fox-farm-sledgehammer","provider":"Hydro Crop Shop","version":"1.0","type":"link"}
