Feed plants during vegetative growth with a 100% natural, plant-based and vegan NPK fertiliser.

HESI Bio Grow is made from fruit and plant extracts, supplemented with mineral ingredients permitted for organic cultivation. Its 4-1-4 nutrient ratio provides nitrogen for foliage and stem development, together with phosphorus and potassium for balanced plant growth.

• Plant-based formula: Made from fruit and plant extracts without animal-derived ingredients.
• Permitted for organic cultivation: Its ingredients meet the requirements for use in organic and biological farming.
• Vegetative nutrient balance: The 4-1-4 formula provides proportionally more nitrogen and potassium for active growth.
• Broad system compatibility: Suitable for soil, coco and hydroponic cultivation.
• Non-crystallising liquid: Designed not to form mineral crystals that could obstruct irrigation pipes or drippers.
• Suitable for manual or automated watering: Can be mixed into water for pots, reservoirs and compatible irrigation systems.
• One feeding programme across different media: Allows growers using several cultivation methods to retain the same growth-phase fertiliser.

HESI identifies the product as 100% natural and vegan. This is more specific than simply describing a fertiliser as “organic”, a term that does not automatically establish how its ingredients were sourced or produced.

Use HESI Bio Grow during the vegetative phase for:

• Aroids and other foliage houseplants
• Indoor and outdoor plants producing active growth
• Soil and organic potting substrates
• Coco-based substrates
• Hydroponic and semi-hydroponic systems
• Manual watering and compatible irrigation systems
• Growers seeking plant-based nutrition without animal ingredients

Change to HESI Bio Bloom or another appropriate flowering fertiliser when a flowering plant enters its bloom phase.

In hydroponic systems, maintain suitable oxygenation and reservoir hygiene. Natural ingredients can support microbial activity, so the nutrient solution and equipment still require regular monitoring and cleaning.

Mix 5 ml per litre of water, equivalent to 50 ml per 10 litres.

Apply during the vegetative growth phase as part of the plant’s normal watering or nutrient routine. Mix thoroughly before applying the solution.

For soil and coco:

• Apply only when the plant requires watering.
• Allow excess solution to drain from containers with drainage openings.
• Reduce feeding when the substrate already contains fertiliser.
• Adjust the frequency to the plant’s growth rate, light and growing conditions.

For hydroponic and semi-hydroponic systems:

• Prepare the nutrient solution with clean water.
• Maintain the pH range required by the plant and system.
• Check the reservoir regularly and replace the solution when necessary.
• Clean pipes, drippers and reservoirs as part of normal system maintenance.

Do not increase the dose solely because the EC appears lower than expected. Nutrients derived from organic compounds may not be represented completely by an EC measurement.

Declared formula:

• NPK 4-1-4
• Fruit and plant extracts
• Naturally occurring magnesium and calcium salts
• Phosphates
• Trace elements
