Ionic Nutrients

The full IONIC range from Growth Technology, relaunched for 2026. A dedicated Grow and Bloom for each medium rather than one base stretched across all of them: Soil, Coco, Hydro for soft or RO water, and a separate Hydro range built for hard tap water.

The hard water bottles are not the same feed in different packaging. They are formulated to deal with the bicarbonates in a hard mains supply, which is what drags your pH up through the week. On most British tap water that is the range to be on.

Four boosters run across all of them. Tonic for calcium and magnesium through the middle of the run, PK at 14:15 over the hungriest weeks, Root Boost in grow and Flower Boost from the flip.

Every IONIC chart is in our feed chart calculator, week by week with the target EC. It will total the bottles for your own run.
