Key features
- One-part feed. No A and B mixing
- Exact K to N ratio for vegetative growth
- Mineral only. Clear, clean and concentrated
- Suits all hydroponic systems
- Dilution / Dose
- 5ml/L in weeks 1–3, rising to 6ml/L from week 4, alongside Root Boost at 0.5–1ml/L.
- When To Use
- Weeks 1–5 of the grow cycle (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 Grow and its own schedule instead. Pair with Root Boost from week 1, and bring in Flower Boost from week 5.
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 Grow 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:
FAQs
Is this the same as Hard Water Grow?
No. Use this formula on soft or RO water. On hard or mains tap water, use Hard Water Grow, which is built to neutralise the extra bicarbonates.
When do I switch to Bloom?
Move onto Hydro Bloom from week 6 of the schedule.
