Plant Magic Nutrients

Plant Magic is a UK-developed nutrient brand with an outstanding reputation for producing genuinely effective, science-backed products at competitive prices. Born from the UK growing community, Plant Magic understands exactly what British indoor growers need — and their range of organic and mineral nutrients, bio-stimulants and additives consistently delivers results that exceed expectations at their price point. We are proud to stock Plant Magic at The Horticulture Company.
Plant Magic Base Nutrients
Plant Magic offers complete base nutrient solutions for soil, coco and hydroponic growing. Old Timer Organic is their flagship organic soil nutrient — made from certified organic plant and animal sources, it provides a rich, biologically active nutrition programme that mirrors the natural feeding ecology of outdoor soil. Supreme Hydro and Supreme Coco are the precision mineral alternatives, using fully chelated mineral inputs for clean, consistent performance in controlled environments.
The Old Timer range is particularly popular with UK organic soil growers who want certification-grade organic inputs without the complexity of multi-product organic programmes. Simply follow the Plant Magic feed chart for straightforward, effective nutrition from propagation to harvest.
Plant Magic Magne-Cal+ and Additives
Magne-Cal+ is one of Plant Magic’s most popular products — a premium calcium, magnesium and iron supplement that prevents the deficiencies commonly seen in soft-water areas of the UK and in coco coir growing environments. Unlike basic Ca-Mg products, Magne-Cal+ includes chelated iron and a full B-vitamin complex that supports overall plant health and metabolic function.
Plant Magic Plus Platinum is their premium bloom booster, delivering L-amino acids, PK supplementation and natural growth regulators to drive increased flower weight and terpene production. We have been supplying Plant Magic to UK growers since 2017. Browse the full range below.
