Plagron Alga Grow 0.1l
Plagron Alga Grow 100 mL is the smallest available packaging of this organic vegetative nutrient derived from seaweed extracts, designed for the growth phase of soil-cultivated plants. This compact bottle contains the same concentrated organic formula with an NPK ratio of 4-2-4 and six trace elements. It serves as a trial-size option for growers evaluating the Alga line, or for single-plant setups where larger volumes are unnecessary. Seaweed-sourced phytohormones and amino acids promote root zone colonisation and photosynthetic efficiency. At 1:250 dilution, 100 mL of concentrate produces up to 25 litres of nutrient solution. Compact format, professional-grade results.

Key specifications
The Alga Grow 100 mL contains the same high concentration of active nutrients as every other format in the range. The biological formulation is based on marine algae extracts, sugar beet vinasse and amino acids.
- Full organic NPK nutrition: 4.2% nitrogen (3.3% organically bound), 2.4% P₂O₅ and 4.3% K₂O covering all macronutrient requirements during vegetative growth
- Six precision-dosed trace elements: iron, manganese, boron, zinc, copper and molybdenum for healthy enzymatic processes and pigment synthesis
- pH of 5.5 falling within the optimal uptake range for soil-grown root systems, typically requiring no additional pH adjustment
- Compact, leak-proof bottle that fits easily into a small grow space or storage area
Application and dosage
Add a maximum of 4 mL of Alga Grow per litre of water and use this nutrient solution at every irrigation during the vegetative phase. From 100 mL of concentrate you can prepare up to 25 litres of working solution, sufficient for one to two plants through a short vegetative cycle. Shake the bottle before each use and store between 0°C and 35°C, protected from frost and direct sunlight. Ready to scale up after your trial run? The Plagron Alga Grow 1L is the natural next step.
Grower benefits

Is 100 mL of Alga Grow sufficient for a complete vegetative cycle?
At the maximum dosage of 4 mL per litre, 100 mL of concentrate yields up to 25 litres of nutrient solution. For a single plant in a 7 to 11 litre container, this typically covers a short vegetative cycle of three to four weeks. For multiple plants or an extended growth phase, a larger format is advisable.
Why select the 100 mL format rather than a larger bottle?
The 100 mL bottle functions as a cost-effective trial format. It allows you to evaluate the performance and results of Alga Grow before investing in a larger volume. It is also a practical option for growers with only one or two plants who prefer not to store surplus product.
Which Alga Grow packaging size offers the best value per litre?
The 5L container provides the most competitive cost per litre, followed by the 1L bottle. The 100 mL format has the highest per-litre price but the lowest absolute purchase cost, making it best suited for trial purposes or small-scale projects.
