BAC Hydro Bloom A & B is a highly concentrated, two-part mineral fertiliser meticulously formulated to provide a complete and balanced feed for plants during the crucial flowering phase in hydroponic systems. During this period, plants require a different ratio of nutrients to produce large, dense flowers and fruits. This powerful formula delivers the ideal balance of phosphorus and potassium, along with high-quality trace elements and red chelate iron. Designed for use on slabs, rock wool, clay pebbles, and other soilless media, this professional-grade nutrient ensures your plants receive everything they need for explosive bloom development and a high-yielding, successful harvest.
Key Benefits of using BAC Hydro Bloom
- Optimised for Hydroponic Flowering: Provides the exact nutrient ratios required for plants to thrive in soilless substrates during the crucial blooming stage.
- Maximises Yield & Density: The ideal balance of phosphorus and potassium directly contributes to the development of larger, heavier, and more resinous flowers.
- Complete Two-Part System: Delivers a full spectrum of essential macro and micronutrients, ensuring your plants receive everything they need in one comprehensive package.
- Enhances Nutrient Absorption: Contains high-quality chelates that improve the plant's ability to absorb nutrients, preventing deficiencies and boosting performance.
- Clean Formulation: The pure mineral salts are highly soluble, preventing blockages and residue in hydroponic irrigation systems.
How to Use BAC Hydro Bloom
BAC Hydro Bloom A & B should be used during the entire flowering period. Always use equal parts of both Bottle A and Bottle B.
- Dosage: Add 30 - 50 ml of Hydro Bloom A and 30 - 50 ml of Hydro Bloom B to 10 litres of water.
- Application: Stir the water thoroughly after adding Component A, then add Component B and stir again. Never mix the concentrated components directly together as this will cause them to become insoluble.
- Frequency: Can be used with every watering.
- For Best Results: Monitor the EC of your nutrient solution, aiming for a value between 1.8 and 2.2, depending on the week of flowering.
For an even more explosive harvest, you can combine this base nutrient with other BAC products like BAC Frooting Power to further increase bud size and hardness. For earlier growth, be sure to use BAC Hydro Grow A & B. You can find a variety of other useful Plant Nutrients on our website.
Available in 1 litre (A & B), 5 litres (A & B) and 10 litres (A & B).
Frequently Asked Questions
Why does this nutrient come in two parts (A & B)?
The key reason is to prevent nutrient lockout. If certain minerals like calcium and phosphate were mixed in their concentrated form, they would react and become insoluble, making them unavailable to your plants. Keeping them separate ensures all nutrients remain usable.Is this product suitable for all hydroponic systems?
Yes, BAC Hydro Bloom A & B is a mineral-based nutrient and is suitable for use in all hydroponic systems as it is highly soluble and won't clog drippers.When should I start using BAC Hydro Bloom A & B?
You should begin using this fertiliser as soon as you see the first signs of flowering. This provides your plants with the essential phosphorus and potassium they need to initiate the blooming process.What is the difference between this and BAC Hydro Grow A & B?
The primary difference is the nutrient ratio. The "Grow" formula has a higher nitrogen content to support vegetative growth, while the "Bloom" formula is specifically designed with an increased amount of phosphorus and potassium to fuel flower development.SKU: 1692Free delivery on orders over £60*
