The THC Grow and Bloom Complete Set bundles both A+B formulas together so you have everything needed to run a complete high-performance crop from seedling to harvest without separate orders or restock gaps mid-cycle.\u003c\/p\u003e\n\n\u003cp\u003eThe Complete Set contains one unit each of THC Grow A+B and THC Bloom A+B in your chosen size, providing the full two-stage nutrient program at a better per-litre cost than buying each formula separately.\u003c\/p\u003e\n\n\u003ch3\u003eThe Two-Stage THC Program\u003c\/h3\u003e\n\n\u003cp\u003eTHC Grow A+B runs from early vegetative growth through to the pre-flower transition. High nitrogen and calcium drive rapid canopy development, thick stem structure, and dense branching that maximises flower site count. Advanced chelation technology maintains micronutrient availability across a wide pH range, reducing deficiency pressure during the fast growth phase of veg.\u003c\/p\u003e\n\n\u003cp\u003eTHC Bloom A+B takes over from the first signs of flowering through to the final week before harvest. Elevated phosphorus and potassium drive flower initiation, bud density, and final harvest weight, while the same pharmaceutical-grade mineral quality and chelation technology that define the Grow formula maintain clean reservoirs and consistent performance throughout the flowering phase.\u003c\/p\u003e\n\n\u003cp\u003eBoth formulas are ultra-concentrated at 2 to 4ml per litre, Australian-formulated for local water conditions, and free from chlorides, sodium, and urea. The result is a clean, efficient, high-performance nutrient system that runs well in DWC, NFT, flood and drain, drip, coco coir, and soil without the complexity of multi-bottle additive programs.\u003c\/p\u003e\n\n\u003ch3\u003eHow to Use the Complete Set\u003c\/h3\u003e\n\n\u003cp\u003eAlways add Part A to your reservoir water first and mix thoroughly before adding Part B. Never combine the concentrates directly. Run THC Grow A+B during the vegetative phase at 2 to 4ml per litre per part, then switch to THC Bloom A+B at the first signs of flowering. Target pH range is 5.5 to 6.5. Check EC after mixing using a calibrated meter and adjust concentration to match the target for the current growth stage.\u003c\/p\u003e\n\n\u003cp\u003eThe \u003ca href=\"\/products\/bluelab-combo-meter-ph-ec-temperature-australia\"\u003eBluelab Combo Meter\u003c\/a\u003e measures pH, EC, and temperature simultaneously, which simplifies daily nutrient management when running a concentrated 2-part system.
