Description
In stock now. A one-part flowering feed, fortified for soil growing.
IONIC Soil Bloom carries the flowering ratio on a base rich in humic and fulvic acids. Less leaching, so nutrients stay where roots can use them, and higher nutrient efficiency makes for stronger, more resilient plants. It works with existing microbial life, whether native or added.
Run vegetative growth on Soil Grow, then switch when flowering starts.
Key features
- One-part feed. No A and B mixing
- Flowering ratio on a humic-rich base
- Less leaching, nutrients stay in the root zone
- Works with native or added microbial life
- Dilution / Dose
- 7ml/L throughout flowering, 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 (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
- Bring in Tonic from week 6 to keep calcium and magnesium available through heavy flowering, add PK from week 8 for the hungriest weeks, and run Flower Boost weeks 5–9 for yield and flavour. Flush with plain water in the final week.
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:
