In stock now. A one-part hydroponic nutrient for flowering and fruiting. One bottle, nothing to mix.
Precisely formulated to support growth, flowering and yield. The potassium to nitrogen ratio shifts for flowering, fruit and yield, and the pH is so stable most tanks need no adjusting.
Run vegetative growth on Hydro Grow, then switch when flowering starts. In a hard water area, use Hard Water Bloom instead.
Key features
- One-part feed. No A and B mixing
- K to N ratio set for flowering and yield
- pH so stable most tanks need no adjusting
- Suits all hydroponic systems
- Dilution / Dose
- 6ml/L tapering to 5ml/L, joined by Tonic at 0.5ml/L from week 6 and PK at 1ml/L from week 8.
- When To Use
- Weeks 6–12; water-only flush in week 13 (soft/RO water)
- Substrate Fit
- Built specifically for hydro on soft/RO water. IONIC doses differently by medium — Soil, Hydro, Hard Water and Coco each have their own schedule, so don't cross them over.
- Grower Notes
- On soft or RO water only — growing on hard or tap water? Use Hard Water Bloom instead. Add Tonic from week 6, PK from week 8, and run Flower Boost weeks 5–9.
Good practice
- Add products to the tank one at a time, stirring between each. Never mix concentrates neat.
- Keep the tank covered — light in stored solution eventually means algae.
- On hard water? Use IONIC Hard Water Bloom and its own schedule instead.
- Measure every dose — eyeballing is where most feed problems start.
The Ionic Range
IONIC is one system, twelve products — a dedicated Grow and Bloom feed for each growing medium, plus four boosters used across all of them. Here's the full range:
