Hesi

We've stocked Hesi for as long as we've been open - they are a long-established nutrient manufacturer from the Netherlands, with more than 25 years of experience in the horticultural market. Known for producing affordable, high-quality feeds, the brand has built its reputation on delivering dependable results without overcomplication. Their formulas are enriched with vitamins, amino acids, and organic elements, helping plants make the most of available nutrition while maintaining strong, healthy growth.

Popular options include Hesi SuperVit, a concentrated plant stimulator containing 25 different vitamins and amino acids to improve nutrient uptake and increase plant resistance, and Hesi Root Complex, an underrated additive that supports root development and helps plants recover quickly from stress. Both products reflect the brand’s focus on straightforward, effective formulas that work well in soil, coco, and hydro systems.

For growers who want vigorous growth and reliable harvests without overspending, we recommend Hesi from Greens Horticulture — offering proven performance, great value, and fast UK delivery.
