Unlock Maximum Harvest Weight with Byron Bay Fruit A+B

The Byron Bay Fruit A+B is the professional-grade Stage 3 fruiting and finisher nutrient that completes the iconic Byron Bay 3-stage system. Formulated with pharmaceutical-grade potassium and phosphorus, this Australian-made dual-part formula is engineered to push plants to their absolute limit during the final weeks of the cycle — maximising fruit density, sugar production, essential oil accumulation, and final harvest weight. While Stage 2 Flower builds the structure, Fruit A+B focuses entirely on density, aroma, and terpene profile at harvest.

Why Byron Bay Fruit A+B is the Ultimate Harvest Finisher

Maximum Brix & Sugar Production: Optimised to accelerate carbohydrate transport, significantly increasing the natural sweetness, flavour, and quality of your final harvest.
The Final Swell Formula: A concentrated hit of high-purity phosphorus and potassium maximises fruit density and final harvest weight during the critical last 4 weeks of the cycle.
Secondary Flowering Response: Triggers a metabolic second wind, ensuring plants finish with a powerful burst of energy rather than tapering off before harvest.
Chelated Micronutrient Saturation: Ensures peak plant health under heavy feeding conditions — no mineral dropout, no lockout, no deficiencies at the finish line.
Hydro & Coco Optimised: High solubility makes it the go-to choice for automated drip, NFT, and DWC systems, while remaining fully compatible with coco coir and soil.

Frequently Asked Questions

How do I mix Byron Bay Fruit A+B correctly?

Always add nutrients to water, never add water to concentrated nutrients. Fill your reservoir with the target volume of fresh water first, then add each part of Byron Bay Fruit A+B separately, stirring between additions. If using a multi-part formula, add micro or Part A first, then grow or bloom, then any additives. Measure pH and EC after mixing and adjust to your target range — typically 5.8–6.2 pH and 1.4–2.2 EC for most crops.

What is the shelf life of Byron Bay Fruit A+B?

Unopened, Byron Bay Fruit A+B has a shelf life of 2 years when stored in a cool, dark location out of direct sunlight. Once opened, use within 12 months. Shake or stir well before each use as some formulations can settle. Do not freeze concentrated nutrients as this can cause precipitation of minerals that will not fully redissolve.

Can I use Byron Bay Fruit A+B in soil as well as hydroponics?

Byron Bay Fruit A+B is formulated for hydroponic systems but can be used for soil and coco growing at adjusted rates. Soil typically requires lower EC than hydro or coco as nutrients are buffered by the growing medium. Start at 50–70% of the recommended hydroponic dose when applying to soil and increase based on plant response.

How do I dispose of leftover nutrient solution made with Byron Bay Fruit A+B?

Dilute spent nutrient solution with water and use it to water outdoor garden beds or lawns — it is an excellent fertiliser for outdoor plants. Avoid disposing of large volumes directly into storm drains. In residential situations, diluted nutrient runoff down a household drain is acceptable in small quantities.

Does Byron Bay Fruit A+B ship fast within Australia?

Yes — Byron Bay Fruit A+B ships from our Australian warehouse with fast tracked delivery Australia-wide. Most east coast orders arrive within 2–5 business days. WA, NT, and TAS orders typically arrive within 5–12 business days.
