Here you will find grow nutrients from BioBizz, Canna, Plagron and Metrop: organic and mineral lines for soil, coco and hydroponics, plus root stimulators, enzymes, bloom boosters, CalMag and pH regulators. Choose the line to match your growing medium and dose with care: the reference EC is 0.8–1.6 mS/cm in the vegetative stage and 1.2–2.0 in flowering.
The growing medium comes first, then the choice between organic and mineral feeding. For a full cycle one base line from the same brand is enough, one product for growth and one for flowering; additives are optional.
Coco binds calcium and magnesium and releases potassium, which is why coco lines have their own formula; in hydroponics all the nutrition comes from the solution.
| Growing medium | pH | Base lines |
|---|---|---|
| Soil | 6.0–7.0 | BioBizz Bio-Grow and Bio-Bloom, Canna Terra Vega and Terra Flores, Canna Bio Vega and Bio Flores, Plagron Terra Grow and Terra Bloom, Plagron Alga Grow and Alga Bloom, Metrop MR1 and MR2 |
| Coco | 5.5–6.5 | Canna Coco A+B, Plagron Cocos A+B, Metrop MR1 and MR2 |
| Hydroponics | 5.5–6.5 | Plagron Hydro A+B, Metrop MR1 and MR2 |
Add the A and B parts to the water one at a time, stirring in between: the two concentrates must never be mixed directly. The complete lines by brand: BioBizz nutrients, Canna, Plagron and Metrop.
The base nutrient supplies nitrogen, phosphorus, potassium and trace elements; additives complement it in one specific area without replacing it.
| Type | Role | Stage | Examples |
|---|---|---|---|
| Grow base | more nitrogen for leaves and stems | vegetative | Bio-Grow, Terra Vega, Terra Grow |
| Bloom base | more phosphorus and potassium | flowering | Bio-Bloom, Terra Flores, Terra Bloom, MR2 |
| Root stimulator | root development | cuttings, seedlings, transplanting | Root-Juice, Rhizotonic, Power Roots, Root+ |
| Enzymes | break down root residues in the medium | whole cycle | Cannazym, Pure Zym, Metrop Enzymes |
| PK booster | targeted phosphorus and potassium | from mid-flowering | PK 13/14 from Canna and Plagron, Green Sensation |
| CalMag | calcium and magnesium | with soft or reverse-osmosis water, in coco | BioBizz CalMag, Metrop Calgreen |
Doses follow the manufacturer's feeding schedule (ml per litre, week by week). Start with a lower dose than stated and only increase it if the plant needs more, checking the EC: 0.4–0.8 mS/cm for seedlings and cuttings, 0.8–1.6 in the vegetative stage, 1.2–2.0 in flowering.
Always adjust the pH after adding the nutrients, because the nutrients themselves shift it. In this category you will find BioBizz pH Plus and pH Minus: add a few drops at a time, stir and measure again. To check pH and EC you need calibrated meters, which you will find among the pH and EC meters.

A base line that matches your growing medium, with a grow and a bloom product from the same brand: for example Bio-Grow and Bio-Bloom in soil or an A+B line in coco.
It depends on the growing medium: organic nutrients are designed mainly for soil, while mineral nutrients can be dosed precisely by EC and are the usual choice in coco and hydroponics.
When the plant enters flowering, which for photoperiod varieties is the switch to 12 hours of light. Many schedules include a few transition weeks in which the grow base continues: follow the one for your brand.
The rows are the weeks, grouped by stage, and the columns are the products with the dose in ml per litre of water, often with the target EC. Read the row for the current week, add the products to the water one by one, then measure EC and pH.
Not for base nutrients: each line is balanced on its own, and two bases together easily lead to overfeeding. A single additive from another brand can be added with care while checking the EC.
