PLAGRON ROYAL MIX 50 LITRE

Description

PLAGRON ROYAL MIX 50 LITRE is the flagship pre-amended growing medium from Plagron, one of Europe’s most respected substrate manufacturers. We have been recommending Plagron Royal Mix to UK soil growers since 2017 because it genuinely delivers on its premium promise: a rich, aerated, biologically active medium that feeds plants naturally for the first 4–6 weeks without any additional base nutrients.

What Makes Royal Mix Stand Out

Plagron Royal Mix combines perlite, peat, coco fibre, and a substantial organic amendment package including worm castings, bat guano, and composted plant matter. The result is a living soil with excellent structure, strong water retention balanced by fast drainage, and a thriving microbial population from day one. The pH is pre-adjusted to sit in the 6.0–6.5 range ideal for soil cultivation, and the added perlite opens up the mix to prevent compaction and ensure roots can explore freely. The 50-litre bag is excellent value per-litre and fills a good number of 10–15 litre containers.

How to Get the Best From Royal Mix

Fill your pots loosely — do not compress the mix — and water lightly to activate the biology before transplanting. For the first two to three weeks water with plain pH-adjusted water only; the built-in nutrient charge will feed your plants through the early vegetative stage. Once the initial charge is used up (watch for a slight yellowing on lower leaves as the signal), introduce a gentle organic feed such as Plagron Liquid Power Roots or Plagron Green Sensation at half-dose to begin supplementing the soil’s natural release. Avoid over-watering — always let Royal Mix partially dry out between waterings to keep the microbial population active and roots oxygenated.

For a complete Plagron organic system, pair Royal Mix 50 Litre with Plagron Alga Bloom and Guanokalong Organic Liquid for a fully natural crop from start to finish.
