Professor's Nutrients - Starter Soak - Ready-to-Use Propagation Formula Professor’s Starter Soak is a scientifically designed, professional-grade nutrient formula engineered to encourage young plants, cuttings, and seedlings to establish roots rapidly. 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. By 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. Best For: 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. Key Features: Perfect 0.5 EC Balance: Precision-blended to a gentle 0.5 EC, offering the perfect low-strength nutritional foundation for young, vulnerable root systems. High-Grade Chelated Minerals: Packed with premium chelated macro and micro trace elements that are easily absorbed by young tissues, maximising nutrient mobility. Ready-to-Use Convenience: No measuring, mixing, or diluting required; pre-mixed at the optimum concentration and balanced pH to save valuable time in the propagation room. Accelerated Development: Actively stimulates early root branching while feeding tender young shoots to ensure strong, uniform early growth across your entire batch. Zero Salt Burn Risk: Formulated to eliminate the risk of overfeeding, ensuring fragile root hairs stay healthy, bright white, and fully functional. Specifications: Feature Details Brand Professor's Nutrients Product Type Ready-to-Use Propagation Nutrient & Media Soak Electrical Conductivity 0.5 EC Application Phase Propagation, Cloning, and Early Seedling Stages Compatible Media Rockwool, Coco Jiffies, Peat Plugs, and Seedling Soils Available Sizes 2.5 Litre, 5 Litre, and 10 Litre Ideal For: Media Pre-Soaking: Soak your rockwool cubes or coco plugs directly in Starter Soak before inserting cuttings to establish an ideal, nutrient-rich environment. Early Stage Feeding: Use as the primary watering solution for newly rooted clones during their first week of development before transitioning to vegetative nutrients. Cloning Tray Maintenance: Apply to propagation trays to keep young root zones consistently moist, fed, and protected against early-stage deficiencies. Usage Tip: For the best results, ensure your propagation media is allowed to drain slightly after soaking so it is moist but not waterlogged. This maintains the perfect air-to-water ratio, allowing the 0.5 EC nutrients and oxygen to work together for explosive root initiation.
