Plagron Lightmix is a professional, low EC substrate with perlite, ideal for seedlings and cuttings. Minimally pre-fertilised for one week, it allows maximum nutrient control. Promotes excellent aeration and rapid root development for superior growth.
Take back control of your cultivation from day one with Plagron Lightmix, the expert blend of high-quality peat moss and liberal amounts of perlite. This premium substrate is designed for growers who prefer to manage their own fertilisation schedule, offering an exceptionally light structure with a minimal nutrient charge. Lightmix is perfectly suited for starting seedlings, rooting cuttings, or serving as the base medium for an entire grow cycle with mineral nutrients.
Key Benefits of Plagron Lightmix
- Maximum Fertiliser Control: Only minimally pre-fertilised for one week with a mineral NPK (12-14-24), allowing growers to administer nutrients (Terra Grow or Alga Grow) from the start based on the plant's exact needs.
- Rapid Rooting: Features a very low Electrical Conductivity (low EC value of 0.7-1.1 mS/cm), which is gentle on young, sensitive roots, encouraging rapid and stress-free root development.
- Superior Aeration and Drainage: The addition of high-quality peat and perlite results in a light, airy substrate with a high oxygen level, drastically reducing the risk of overwatering and root rot.
- Versatile Growing Styles: Perfect for use with Plagron's 100% TERRA line (mineral feeds for fast results) or can be easily converted to work with their 100% NATURAL line (organic feeds for enhanced taste).
- High Quality Substrate: A premium mix of carefully selected types of peat, providing a consistent and stable environment throughout the entire growth cycle.
How to Use Plagron Lightmix
Plagron Lightmix is a substrate for direct use when planting or transplanting, giving you complete flexibility in your feeding strategy.
- Preparation: Fill your chosen pots with Lightmix. The medium is intentionally light; avoid pressing or compacting the soil.
- Planting: Plant your cuttings, seedlings, or flowering plants directly into the mix. A seedling of 1-2 weeks old is typically ready for Lightmix.
- Initial Watering: Water the medium thoroughly until you achieve a small amount of runoff.
- Feeding Schedule: The minimal pre-fertilisation lasts for approximately one week. You should start fertilising after the first week with your chosen liquid nutrient, such as Plagron Terra Grow for mineral grows or Plagron Alga Grow if switching to the organic line. Use Plagron additives like Green Sensation during the bloom phase for optimal results.

Frequently Asked Questions
When should I start giving liquid nutrition if I use Plagron Lightmix?
Plagron Lightmix is pre-fertilised for one week only. You should begin administering your chosen liquid base nutrient, such as Plagron Terra Grow, immediately after this first week.Do I need to monitor the pH and EC values when growing on Lightmix?
Yes. Lightmix is minimally charged with mineral fertilisers, and the 100% TERRA line nutrients (like Terra Grow and Terra Bloom) are mineral-based. Therefore, to ensure maximum nutrient absorption and prevent nutrient lock-out, it is crucial to monitor and regulate both the pH and EC of your nutrient solution.Can I use organic nutrients with Lightmix?
Yes, you can. Although Lightmix is minimally charged with mineral nutrients, you can switch to an organic feeding line like Biobizz once the initial mineral feed has been depleted (after about one week). This allows you to grow organically with the benefit of the Lightmix's airy structure.SKU: 1061Free delivery on orders over £60*
