Ionic Hydro Grow — Complete One-Part Hydroponic Nutrient for Vegetative Growth
Best for: Growers wanting straightforward hydroponic feeding without A&B mixing, from beginners to commercial setups
Our thoughts
This is proper one-part hydroponic nutrient that actually delivers. Fully complexed minerals, pH stable, and no mixing drama. We rate it for growers who want consistency without the faffing—and that covers most people getting started in hydroponics.
Ionic Hydro Grow is a complete single-bottle hydroponic nutrient designed for the vegetative stage in soft water areas. It contains all 14 essential macro and micro elements your plants need, fully complexed and locked into large molecules during manufacturing to ensure precise nutrient delivery. One bottle. One dosing rate. No measuring separate A and B parts. Just fill, add 7ml per litre, check your EC, and grow.
How it compares
One-part nutrients sit in a sweet spot between simplicity and precision.
-
vs. two-part systems: Easier to use, fewer mistakes, lower staff training overhead. Two-parts offer marginally more micronutrients, but Ionic's chelation process compensates well
-
vs. powder solutions: Ready to use, no manual mixing, consistent results every time
-
vs. premium branded one-parts: Same functional performance at a lower price point
The real difference here is Ionic's fully complexed formulation—minerals are bound together at manufacturing stage, not mixed in the tank. That's claimed to be unique in the market.
Usage guidance
Ionic Hydro Grow works across all inert-media hydroponic systems.
NFT (Nutrient Film Technique)
Add 7ml per litre to your tank. Target EC of 2.0. Simple and low-maintenance.
Flood & Drain (Ebb & Flow)
Same 7ml/litre dosing. EC 2.0 works well with clay pebbles.
Rockwool systems
Reduce to EC 1.5 to avoid overfeeding in the more absorbent medium.
pH stability
Ionic uses reactive buffering during manufacture, so pH stays stable in your tank with minimal adjustment needed. That's the real win here—less monitoring, fewer corrections.
Measuring and monitoring
Use a syringe or calibrated beaker for accurate dosing. Monitor EC/PPM with a meter like the Bluelab Truncheon. That's genuinely all you need to do.
Yield efficiency
1 litre makes up to 142 litres of nutrient solution. One bottle goes a long way.

Who this is for
- First-time hydroponic growers wanting to skip the complexity of two-part or multi-part systems
- Commercial operations running multiple tanks where consistency and staff efficiency matter
- Growers in soft water areas looking for a formulation that just works without water chemistry headaches
- Anyone tired of measuring separate A and B bottles and still getting it wrong
- Existing hydroponics users switching to a simpler feeding schedule without sacrificing results
Particularly suited to anyone who wants reliable, predictable nutrient delivery without the faffing.
Our take
This is a properly formulated hydroponic nutrient that does exactly what it promises. No mixing drama, pH stays put, and the fully complexed mineral profile means your plants get what they need without any guesswork. One-part nutrients get a lot of stick from purists, but in reality this is what most commercial growers use because it works and cuts down errors.
If you're setting up hydroponics for the first time or just want feeding to be genuinely simple, worth picking up while stock lasts. Does the job day in, day out.
