BAC Hydro Grow A&B – Power Your Veg Stage
BAC Hydro Grow A&B is a concentrated two-part nutrient made for hydro growers who want fast, healthy vegetative growth. Packed with balanced minerals, premium trace elements and chelated iron, it builds strong roots, thick stems and lush green growth from the start.
Designed for hydro systems using rockwool, clay pebbles or perlite, this clean, soluble formula keeps your lines clear and your plants thriving.
Why growers love it:
- Built for hydro – perfectly balanced for soilless media
- Two-part system – stops nutrient lockout
- Drives fast growth – strong roots, dense foliage
- Highly concentrated – a little goes a long way
- Clean feed – no blockages, no residue
- Dilution / Dose
- 25–35ml of Part A and 25–35ml of Part B per 10L of water. Add A first, stir, then add B — never combine the concentrates directly. Feed every watering, targeting an EC of around 1.6.
- When To Use
- Throughout vegetative growth. Switch to Hydro Bloom AB at the first signs of flowering.
- Substrate Fit
- Hydro / soilless media only — rockwool, clay pebbles, perlite. Not for coco or soil.
- Grower Notes
- Pairs with BAC Hydro Bloom AB as the bloom half of BAC's two-part hydro system. For even stronger roots, pair with BAC Root Stimulator.
Available in 1L, 5L and 10L sets (A & B).
