Bloom GROIGEN Super Concentrate — Foliar Growth Enhancer for Vegetative Development
Best for: Growers wanting to boost leaf expansion and branch development without complicating their base nutrient schedule
Our thoughts
GROIGEN sits in that sweet spot where it actually earns its place in your feeding routine. Natural plant extracts and fulvic acid doing real work on photosynthesis and nutrient uptake. Mix it into your spray schedule and you'll see thicker stems and faster leaf expansion without having to rethink your whole nutrient programme.
Bloom GROIGEN is a premium foliar spray concentrate designed to accelerate leaf and branch development during the vegetative growth phase. Built on natural plant extracts, fulvic acid, vitamins, and amino acids, it works by enhancing nutrient uptake and boosting photosynthesis from the top down. Unlike many foliar products that force you to dial back your base nutrients, GROIGEN plays nicely with your existing feeding schedule — you mix it, spray it, and move on.
How it compares
GROIGEN occupies the mid-to-premium tier of foliar sprays, positioning itself as an organic-focused alternative to mass-market options.
- Natural, organic-derived formula vs. purely synthetic competitors
- Fulvic acid inclusion for enhanced nutrient bioavailability — not just a vitamin spray
- Works across all growing media and methods without restriction
- Designed as part of an integrated nutrient system, but functions standalone
- More specialised than general-purpose foliar feeds; more targeted than base nutrients alone
In practical terms, you're getting a genuinely functional growth enhancer that doesn't force you to overhaul your feeding strategy.
Usage guidance
GROIGEN is applied as a foliar spray, not through the roots. Application is straightforward but technique matters.
Mixing and application
Mix at 20ml per litre of water. Fill your sprayer, spray plants thoroughly when lights are off to avoid leaf burn. Apply during the vegetative growth phase, right through from clones and seedlings to the end of your growing cycle.
Timing and frequency
Spray when the grow lights are off — early morning or late evening in a natural light setup. Once or twice weekly works well depending on plant vigour and your existing nutrient programme. You don't need to reduce your base nutrient dose to use this product.
In integrated systems
GROIGEN complements the full Bloom Yellow Bottle nutrient line (Grow A, Grow B, and specialist additives), but it's equally effective with any other brand. Treat it as a supplement that boosts what your base nutrients are already doing.
In different growing setups
Works equally well in soil, coco, hydroponics, and run-to-waste systems. Spray application means no medium-specific adjustments needed.

Who this is for
- Growers using the full Bloom Yellow Bottle nutrient system who want integrated support
- Anyone transitioning from synthetic to organic-derived nutrient lines
- Experienced growers looking to optimise leaf expansion and stem thickness without overhauling their feeding schedule
- Operators where photosynthesis boost translates directly to faster crop turnover
- Growers with root absorption limitations who benefit from foliar nutrient uptake
Less suited to complete beginners building their first system — this is a refinement product, not a foundation one. Best added once you've got your base nutrients and watering dialled in.
Our take
GROIGEN does a proper job. Fulvic acid and natural plant extracts actually work on nutrient uptake and photosynthesis, not just a label claim. Mix it at 20ml per litre, spray when the lights are off, and you'll see measurable thicker stems and faster leaf development.
If you're running a serious vegetative setup or want to squeeze more out of your existing nutrient programme without complications, worth picking up. Does exactly what it should, day in, day out.
