Pre-mixed and ready to use straight from the bottle, this specialised soak features a perfectly balanced pH and a precise, ultra-low electrical conductivity (0.5 EC) tailored specifically for highly sensitive young root zones. It provides the ideal bridge between plain water and full-strength vegetative fertilisers.\u003c\/p\u003e\n\n\u003cp\u003eBy delivering a gentle yet complete profile of high-grade chelated micro and macro trace elements, Starter Soak ensures optimal nutrient absorption without the risk of salt burn. It is the ultimate plug, cube, and media conditioner for growers looking to accelerate early root and shoot development during the most fragile stage of the crop cycle. Using Starter Soak eliminates the guesswork, ensuring your clones and seedlings have the perfect nutritional start every time.\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003cp\u003e\u003cb\u003eBest For:\u003c\/b\u003e Pre-soaking starter plugs, rockwool cubes, and propagation media, accelerating root strike in fresh cuttings, preventing nutrient burn in delicate seedlings, and driving rapid early growth.\u003c\/p\u003e\n\n\u003cp\u003e\u003cb\u003eKey Features:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cb\u003ePerfect 0.5 EC Balance:\u003c\/b\u003e Precision-blended to a gentle 0.5 EC, offering the perfect low-strength nutritional foundation for young, vulnerable root systems.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eHigh-Grade Chelated Minerals:\u003c\/b\u003e Packed with premium chelated macro and micro trace elements that are easily absorbed by young tissues, maximising nutrient mobility.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eReady-to-Use Convenience:\u003c\/b\u003e No measuring, mixing, or diluting required; pre-mixed at the optimum concentration and balanced pH to save valuable time in the propagation room.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eAccelerated Development:\u003c\/b\u003e Actively stimulates early root branching while feeding tender young shoots to ensure strong, uniform early growth across your entire batch.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eZero Salt Burn Risk:\u003c\/b\u003e Formulated to eliminate the risk of overfeeding, ensuring fragile root hairs stay healthy, bright white, and fully functional.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cb\u003eSpecifications:\u003c\/b\u003e\u003c\/p\u003e\n\u003ctable style=\"width: 100%; border-collapse: collapse; text-align: left;\"\u003e\n  \u003ctr style=\"border-bottom: 1px solid #ccc;\"\u003e\n    \u003cth style=\"padding: 8px;\"\u003eFeature\u003c\/th\u003e\n    \u003cth style=\"padding: 8px;\"\u003eDetails\u003c\/th\u003e\n  \u003c\/tr\u003e\n  \u003ctr style=\"border-bottom: 1px solid #eee;\"\u003e\n    \u003ctd style=\"padding: 8px;\"\u003e\u003cb\u003eBrand\u003c\/b\u003e\u003c\/td\u003e\n    \u003ctd style=\"padding: 8px;\"\u003eProfessor's Nutrients\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr style=\"border-bottom: 1px solid #eee;\"\u003e\n    \u003ctd style=\"padding: 8px;\"\u003e\u003cb\u003eProduct Type\u003c\/b\u003e\u003c\/td\u003e\n    \u003ctd style=\"padding: 8px;\"\u003eReady-to-Use Propagation Nutrient \u0026amp; Media Soak\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr style=\"border-bottom: 1px solid #eee;\"\u003e\n    \u003ctd style=\"padding: 8px;\"\u003e\u003cb\u003eElectrical Conductivity\u003c\/b\u003e\u003c\/td\u003e\n    \u003ctd style=\"padding: 8px;\"\u003e0.5 EC\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr style=\"border-bottom: 1px solid #eee;\"\u003e\n    \u003ctd style=\"padding: 8px;\"\u003e\u003cb\u003eApplication Phase\u003c\/b\u003e\u003c\/td\u003e\n    \u003ctd style=\"padding: 8px;\"\u003ePropagation, Cloning, and Early Seedling Stages\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr style=\"border-bottom: 1px solid #eee;\"\u003e\n    \u003ctd style=\"padding: 8px;\"\u003e\u003cb\u003eCompatible Media\u003c\/b\u003e\u003c\/td\u003e\n    \u003ctd style=\"padding: 8px;\"\u003eRockwool, Coco Jiffies, Peat Plugs, and Seedling Soils\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr style=\"border-bottom: 1px solid #eee;\"\u003e\n    \u003ctd style=\"padding: 8px;\"\u003e\u003cb\u003eAvailable Sizes\u003c\/b\u003e\u003c\/td\u003e\n    \u003ctd style=\"padding: 8px;\"\u003e2.5 Litre, 5 Litre, and 10 Litre\u003c\/td\u003e\n  \u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003cp\u003e\u003cb\u003eIdeal For:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cb\u003eMedia Pre-Soaking:\u003c\/b\u003e Soak your rockwool cubes or coco plugs directly in Starter Soak before inserting cuttings to establish an ideal, nutrient-rich environment.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eEarly Stage Feeding:\u003c\/b\u003e Use as the primary watering solution for newly rooted clones during their first week of development before transitioning to vegetative nutrients.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eCloning Tray Maintenance:\u003c\/b\u003e Apply to propagation trays to keep young root zones consistently moist, fed, and protected against early-stage deficiencies.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cb\u003eUsage Tip:\u003c\/b\u003e For the best results, ensure your propagation media is allowed to drain slightly after soaking so it is moist but not waterlogged.
