Terra Aquatica TriPart FloraGro - Vegetative-Stage Base Nutrient
Best for: Growers running a three-part feeding programme who need the vegetative-growth base nutrient to pair with FloraBloom and FloraMicro.
Our thoughts
This is the vegetative half of Terra Aquatica's TriPart system - and Terra Aquatica is simply the European rebrand of General Hydroponics, so you're getting one of the most established base nutrient formulas in hydroponics, not an unproven newcomer. If you're building a feed programme from scratch, this is a sensible, well-understood place to start.
TriPart FloraGro is the vegetative-growth component of Terra Aquatica's three-part base nutrient system, formulated with a nitrogen-forward ratio to support strong stem and leaf development before plants move into flower. Used alongside FloraBloom (flowering stage) and FloraMicro (micronutrients, used throughout), the three-part structure lets you shift the balance of the feed as the plant's needs change - FloraGro-heavy during veg, tapering down as FloraBloom increases through flowering.
How it compares
One of the most established base nutrient formulas on the market, sold under different names depending on region.
- Directly equivalent to General Hydroponics' FloraGro, sold in the US and elsewhere under the original General Hydroponics branding - Terra Aquatica is that same company's European identity, not a competing formula.
- Compared to two-part systems like Canna Coco A+B, the three-part structure gives finer control over the grow-to-bloom ratio through the cycle, at the cost of an extra bottle to manage.
- Compared to premium three-part ranges like Advanced Nutrients' pH Perfect Grow/Micro/Bloom, TriPart sits at a lower price point without built-in pH buffering, so pH still needs manual checking.
A well-proven formula rather than a new or unusual one - the main trade-off against pricier three-part systems is manual pH management.
Usage guidance
Early vegetative growth
Use FloraGro as the dominant component of your feed from the seedling/cutting stage through to established veg, following Terra Aquatica's published feed chart.
Transition to flower
Gradually reduce the FloraGro ratio relative to FloraBloom as plants move into pre-flower and flower - dosage is commonly cited in the region of 0.5-2.0ml/L, higher in veg and tapering down through flowering.
Mixing order
Add FloraMicro first, then FloraGro, then FloraBloom, stirring well between each addition rather than combining concentrates directly.
Reservoir use
Suitable for recirculating hydro systems as well as hand watering in coco or soil - adjust concentration to your growing medium and check EC/pH after mixing.

Who this is for
- Growers building a Terra Aquatica TriPart feeding programme from scratch
- Growers wanting finer control over their veg-to-bloom nutrient ratio than a single-bottle feed allows
- Anyone switching from General Hydroponics' US Flora Series and wanting the equivalent European product
- Larger grows where buying the 5L or 10L size brings the per-litre cost down significantly
Buy alongside FloraBloom and FloraMicro if you're starting the system from scratch - buying FloraGro on its own only makes sense if you're already running the other two.
Our take
TriPart FloraGro is a known quantity - the same formula behind General Hydroponics' Flora Series, rebranded for the European market, with decades of real-world use behind it. Buy the size that matches your reservoir volume and growing scale to avoid paying for concentrate you won't use before it degrades.
One we sell a lot of for growers who want a base nutrient they can trust without having to guess. Proper kit at a price that makes sense.
