BioBizz Bio-Grow - Organic Base Nutrient for Strong Vegetative Growth
Best for: growers wanting a fully organic, all-in-one vegetative feed for soil, coco or automated irrigation systems.
Our thoughts
Bio-Grow is the workhorse of the BioBizz range, the bottle most growers reach for first. It's not flashy, it just gets plants through the vegetative stage on an organic feed without any fuss, and it plays nicely with the rest of the BioBizz line when you move into flower.
Bio-Grow is BioBizz's 100% organic base fertiliser for the vegetative stage, with an NPK ratio of 4-3-6. Like the rest of the BioBizz range, it's built on 100% Dutch organic sugar beet extract, known as vinasse, a natural fermentation by-product of processing sugar beet or sugar cane. On top of the core NPK, Bio-Grow carries around 70 trace elements plus vitamins B1, B2, C and E, giving plants a broader nutritional base than a straight mineral feed while also activating the bacterial flora in the growing medium.
It's designed for soil, coco and automated irrigation systems, and BioBizz recommend a dosage of 2 to 4ml per litre of water at regular feeds. It's typically run through the vegetative stage before being tapered out as Bio-Bloom takes over for flowering.
How it compares
Bio-Grow's position in the market is straightforward: it's the organic, vinasse-based alternative to mineral vegetative feeds.
- Vs Canna Terra Vega: Terra Vega is a mineral-based one-part veg feed with a similar-strength NPK (3-1-3), giving more precise control but no organic certification.
- Vs Emerald Harvest Grow: Grow is a mineral 3-part base nutrient (NPK 2-1-6) designed to be mixed with Micro and Bloom, offering more granular control at the cost of extra bottles and no organic status.
- Vs BioBizz's own Fish-Mix: Fish-Mix pushes nitrogen harder for faster foliage bulk-up, while Bio-Grow is the more balanced, general-purpose vegetative feed of the two.
If you want a genuinely organic vegetative feed that doubles as a complete nutritional base rather than just an NPK delivery system, Bio-Grow is one of the more established options.
Usage guidance
A simple single-bottle dosing routine through veg.
Dosage
Use 2 to 4ml of Bio-Grow per litre of water at each regular feed, adjusting up toward the higher end for larger or heavier-feeding plants.
Timing
Run Bio-Grow through the vegetative stage, then start tapering it out as you introduce Bio-Bloom once plants switch to flowering.
Automated systems
Bio-Grow is suitable for drip and automated irrigation setups as well as hand watering, so it works across most soil and coco growing systems.
