Description

Plagron ProMix 50 Litre is a premium, professionally formulated soil growing medium from Plagron, pre-mixed with perlite, peat and organic matter to provide an immediately ready-to-use substrate for pot-based indoor cultivation. We have been recommending Plagron growing media to UK soil growers since 2017 as a high-quality Dutch growing medium brand that produces consistent, well-structured substrate batches suitable for demanding indoor growing programmes.

A Professional Soil Mix Ready from First Use

Plagron ProMix is designed to deliver optimal growing conditions from the moment you plant — correct air-to-water ratio through the perlite fraction, appropriate organic matter content for biological activity and moisture retention, and a pH pre-adjusted to the optimal range for soil growing. This ready-to-use characteristic eliminates the effort and inconsistency of home-mixed growing media, ensuring every batch of ProMix provides the same reliable substrate performance that allows you to plan and execute your feeding programme confidently without adjusting for medium variability.

The balanced perlite fraction in ProMix ensures good drainage and aeration between watering cycles, preventing the waterlogging and root zone oxygen depletion that can occur in heavy peat-only soils under frequent watering. This air-to-water balance is particularly important in grow rooms where watering frequency may be higher than in outdoor growing, and where root zone health is critical to plant performance under intensive artificial lighting.

Compatibility and Programme Integration

Plagron ProMix is compatible with all liquid nutrient programmes — Plagron Terra Grow and Bloom, Biobizz, DutchPro Soil, or any other quality soil nutrient range. The medium is suitable for both hand-watered and automated irrigation systems in pot-based growing. Fill containers to within 5cm of the rim, pre-wet before planting, and introduce nutrients from first watering at an appropriate seedling-to-vegetative transition EC.

Pairs with Plagron Terra Grow and Bloom nutrients, Megaworm soil conditioner and the full Plagron additive range for a matched, cohesive Plagron soil growing programme. Available in 50-litre bags for single to multi-pot filling. A well-regarded professional soil mix for UK indoor cultivators.
