Heavy fertiliser use compromises plant growth over time as mineral salts concentrate in the root zone, eventually restricting how well roots can take up water and nutrients even when feed levels are correct.\u003c\/p\u003e\u003cp\u003eSledgeHammer is derived from saponins extracted from the Yucca schidigera plant, which is what makes it OMRI Listed and a registered CDFA organic input material — it can be used in organic growing as well as conventional hydroponic and soil setups. It is worked into a weekly feeding schedule at a low rate in hydro systems, run through the system with every reservoir change, and used for a dedicated flush every two weeks to relieve nutrient lockout before it becomes a visible problem.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eYucca-derived saponins\u003c\/strong\u003e that encourage water movement through media\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOMRI Listed and CDFA registered\u003c\/strong\u003e organic input material\u003c\/li\u003e\n\u003cli\u003eHelps \u003cstrong\u003erelieve nutrient lockout\u003c\/strong\u003e caused by mineral salt build-up\u003c\/li\u003e\n\u003cli\u003eWorks as a \u003cstrong\u003eweekly additive or a dedicated flush\u003c\/strong\u003e depending on need\u003c\/li\u003e\n\u003cli\u003eSuitable for \u003cstrong\u003eboth hydroponic and soil\u003c\/strong\u003e applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003cdiv class=\"hcs-specs\"\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eDerived from Yucca schidigera saponins\u003c\/li\u003e\n\u003cli\u003eCertification: OMRI Listed, Registered CDFA Organic Input Material\u003c\/li\u003e\n\u003cli\u003eContainer\/in-ground dose: 10ml per 4L fresh water, drench thoroughly, every 3-4 weeks to harvest\u003c\/li\u003e\n\u003cli\u003eHydroponic weekly dose: 2 drops per 4L fresh reservoir water, combined with weekly feed\u003c\/li\u003e\n\u003cli\u003eFlush dose: 2.5ml per 4L fresh reservoir water, full system flush every two weeks, cycle one hour and change reservoir\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\u003cdiv class=\"hcs-dosing\" style=\"margin:32px 0 0;border:1px solid #e6e6e6;border-radius:12px;overflow:hidden;font-family:Montserrat,-apple-system,'Segoe UI',sans-serif;\"\u003e\n\u003cdiv style=\"background:#101010;padding:16px 20px;border-bottom:3px solid #efc04c;\"\u003e\n\u003cdiv style=\"color:#ffffff;font-size:17px;font-weight:600;letter-spacing:.06em;text-transform:uppercase;\"\u003eFeed Chart\u003c\/div\u003e\n\u003cdiv style=\"margin-top:6px;color:#b8b8b8;font-size:12px;line-height:1.5;\"\u003eFoxFarm Bush Doctor SledgeHammer · soil, containers and hydroponics\u003c\/div\u003e\n\u003c\/div\u003e\n\u003ctable style=\"width:100%;border-collapse:collapse;font-size:14px;color:#2b2b2b;background:#fff;\"\u003e\n\u003ctr style=\"background:#f4f4f4;\"\u003e\n\u003cth style=\"text-align:left;padding:10px 20px;font-size:11px;letter-spacing:.08em;text-transform:uppercase;color:#6b6b6b;font-weight:600;\"\u003eApplication\u003c\/th\u003e\n\u003cth style=\"text-align:right;padding:10px 14px;font-size:11px;letter-spacing:.08em;text-transform:uppercase;color:#6b6b6b;font-weight:600;white-space:nowrap;\"\u003ePer 1 L\u003c\/th\u003e\n\u003cth style=\"text-align:right;padding:10px 20px;font-size:11px;letter-spacing:.08em;text-transform:uppercase;color:#6b6b6b;font-weight:600;white-space:nowrap;\"\u003ePer 10 L\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:12px 20px;border-top:1px solid #ededed;\"\u003eContainers and in-ground — drench thoroughly, every 3 to 4 weeks to harvest\u003c\/td\u003e\n\u003ctd style=\"padding:12px 14px;border-top:1px solid #ededed;text-align:right;white-space:nowrap;font-weight:600;\"\u003e2.5 ml\u003c\/td\u003e\n\u003ctd style=\"padding:12px 20px;border-top:1px solid #ededed;text-align:right;white-space:nowrap;color:#6b6b6b;\"\u003e25 ml\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#fcfaf4;\"\u003e\n\u003ctd style=\"padding:12px 20px;border-top:1px solid #ededed;\"\u003eHydroponic full-system flush — every two weeks\u003c\/td\u003e\n\u003ctd style=\"padding:12px 14px;border-top:1px solid #ededed;text-align:right;white-space:nowrap;font-weight:600;\"\u003e0.63 ml\u003c\/td\u003e\n\u003ctd style=\"padding:12px 20px;border-top:1px solid #ededed;text-align:right;white-space:nowrap;color:#6b6b6b;\"\u003e6.3 ml\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003cdiv style=\"background:#101010;padding:12px 20px;font-size:12px;color:#b8b8b8;line-height:1.6;\"\u003e\n\u003cspan style=\"color:#efc04c;font-weight:600;\"\u003eNote\u003c\/span\u003e — FoxFarm publish these as 10 ml and 2.5 ml per 4 L of fresh water.
