Plagron is a Dutch brand known for its clear feeding schedules and lines for soil, coco and hydro. In this collection you'll find the base nutrients Terra Grow and Terra Bloom for soil, Coco A & B and Hydro A & B, plus Alga Bloom for organic growers and a set of additives: Power Roots, Vita Start, Vita Race, Pure Enzym, Silic Rock, Calmag Pro, Sugar Royal, Power Buds, PK 13-14 and Green Sensation, as well as pH+ and pH-.
Base nutrient first, additives second
Start by choosing the base line for your medium. Terra Grow and Terra Bloom are a popular pairing for soil, Coco A & B is made for coco fibre and Hydro A & B for water-based systems. Additives then fine-tune the grow: Power Roots stimulates root development early on, Pure Enzym helps keep the root zone clean, and Green Sensation or PK 13-14 support the flowering phase. Use one bloom booster at a time rather than stacking several.
Sizes and practical tips
Most Plagron products come in 1, 5 and 10 litres, and the Terra bases also in 20 litres for larger grows. Follow the schedule, start below the full dose with young plants and check pH and EC after mixing using a meter from pH & EC meters. Our nutrient guide explains the phases in detail. Pair your feed with a suitable growing medium from substrates, or compare with other nutrient brands.
