In stock now. A one-part vegetative feed, fortified for soil growing.
IONIC Soil Grow is heavily fortified with humic and fulvic acids. Humic acids improve soil structure and the air to water ratio, act as a natural chelator lifting nutrient availability and uptake, and feed soil microbes with organic carbon.
Switch to Soil Bloom when flowering starts.
Key features
- One-part feed. No A and B mixing
- Heavily fortified with humic and fulvic acids
- Improves soil structure and nutrient uptake
- Feeds soil microbes with organic carbon
- Dilution / Dose
- 5ml/L in weeks 1–2, rising to 7ml/L from week 3, alongside Root Boost at 0.5–1ml/L.
- When To Use
- Weeks 1–5 of the grow cycle (soil)
- Substrate Fit
- Built specifically for soil. IONIC doses differently by medium — Soil, Hydro, Hard Water and Coco each have their own schedule, so don't cross them over.
- Grower Notes
- Pair with Root Boost from week 1 for stronger root establishment, and bring in Flower Boost from week 5 as the plant transitions toward flower. Switch to Soil Bloom once flowering begins.
Good practice
- Add products to the water one at a time, stirring between each. Never mix concentrates straight from the bottle.
- Keep any stored solution covered — light in stored solution eventually means algae.
- Every medium doses differently. IONIC Hydro, Coco and Soil each have their own schedule.
- 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
Can I use Soil Grow in coco or hydro?
No — use the matching medium-specific formula: Hydro Grow or Coco Grow. Soil Grow is formulated with humic and fulvic acids for soil structure specifically.
When do I switch to Bloom?
Move onto Soil Bloom from week 6 of the schedule, once flowering is properly underway.
Do I need Cal-Mag with Soil Grow?
Most soil growers don't need extra calcium and magnesium early on. If you see deficiency symptoms, add Tonic.
