BAC Hydro Bloom A&B – Fuel Your Flowering Phase
BAC Hydro Bloom A&B is a concentrated two-part feed designed to push plants through heavy flowering in any hydro system. With the perfect balance of phosphorus, potassium, and essential trace elements, it delivers the power your plants need for dense, high-yielding blooms.
Made for soilless media like rockwool, clay pebbles, and slabs, this clean, soluble formula keeps your system clear while giving plants everything they need for explosive flower development.
Why growers love it:
- Built for hydro flowering – perfect balance of nutrients for bloom stage
- Maximises yield and density – bigger, heavier flowers
- Two-part system – prevents lockout and boosts uptake
- Enhanced absorption – premium chelates for better nutrient delivery
- Clean formulation – fully soluble, no clogs or residue
- Dilution / Dose
- 30–50ml of Part A and 30–50ml of Part B per 10L of water. Add A first, stir well, then add B — never combine the concentrates directly. Feed every watering, targeting an EC of 1.6–2.2 — starting around 1.8, peaking at 2.2 by week 5, then dropping back to 1.6 for the final three weeks.
- When To Use
- Throughout the flowering phase, starting as soon as you see the first signs of flowers.
- Substrate Fit
- Hydro / soilless media only — rockwool, clay pebbles, slabs. Not for coco or soil.
- Grower Notes
- Pairs with BAC Hydro Grow AB for the vegetative stage. For bigger, denser blooms, pair with BAC Frooting Power.
Available in 1L, 5L, and 10L sets (A & B).
