Hesi Bio Grow 500 ml (Bio Hesi Grow) – organic, vegan fertilizer for the growth phase

Bio Hesi Grow is a liquid plant-based NPK fertilizer developed for people who want to feed their plants organically with a 100% natural product. The formula is based exclusively on fruit and plant extracts, making the fertilizer fully vegan, while its ingredients meet the requirements for organic farming, as stated by the manufacturer.

Compared with the Bloom version, the Grow formula contains less phosphorus and a higher proportion of nitrogen – the nutrient that drives leaf and shoot growth. The manufacturer describes it as powerful nutrition that is also gentle on plants and environmentally friendly.

The fertilizer is completely liquid and does not crystallize, so it does not clog lines or drippers. It can be used with any growing method: in soil, coco substrate and hydroponics; the manufacturer also confirms its suitability for vertical gardens.

Composition and NPK analysis

A liquid, plant-based organic NPK fertilizer with an NPK ratio of 4-1-4 (nitrogen – phosphorus – potassium), made from fruit and plant extracts. The magnesium and calcium salts, phosphates and micronutrients it contains are substances that occur naturally in soil and compost.

Application
