THC Grow and Bloom Complete Set | Full-Cycle High-Concentrate Hydroponic Nutrient System Australia

Running the full THC system means having both the vegetative and flowering formulas on hand before you start, with the right nutrient for each growth stage ready to go at the transition. 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.

The 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.

The Two-Stage THC Program

THC 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.

THC 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.

Both 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.

How to Use the Complete Set

Always 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.

The Bluelab Combo Meter measures pH, EC, and temperature simultaneously, which simplifies daily nutrient management when running a concentrated 2-part system. For a pre-harvest flush in the final week, TA FlashClean clears residual salts from the root zone and growing media.
