Plagron Lightmix is a mix of the very best, carefully selected types of peat. The addition of various types of fibre and perlite results in a lightness and oxygen level found only in Plagron quality substrates. Only a minimal amount of nutrients have been added to Lightmix. This makes Lightmix the perfect substrate to fertilise according to your own judgement and choices. Lightmix produces the highest yields when used with Plagron Terra Grow, Terra Bloom and the additives from Plagron. Lightmix: also available without perlite.


  • Peat moss, perlite.
  • pH (H2O) 6 - 7
  • EC (mS/cm) 0,7 - 1,1
  • NPK fertiliser 12-14-24


Plagron Lightmix is a substrate for direct use when you are planting and transplanting flowering plants. Start fertilising after the first week.


  1. When can I start giving nutrition if I use Lightmix?

    Lightmix is already pre-fertilised for one week. Start giving nutrients after one week.
  2. Should I regulate the pH and EC value if I grow on Lightmix?

    Yes, Lightmix is made to be used with mineral nutrients. This means that the pH value and EC value affect the absorption of the nutrients. Therefore, it's important that you keep a close eye on it.
  3. Can I use Alga Grow and Alga Bloom on the 100% TERRA substrates Lightmix?

    Yes, you can, once the mineral fertiliser is out of the substrate. With Lightmix that will take about a week. As long as there are nutrients in the substrate, you'll have to monitor pH and EC values. You won't need to add nutrients. Once the pre-fertilisation is gone, you can start adding Alga Grow or Bloom and you won't need to monitor anything anymore. In the period between the two you'll only have to mind the pH. Alga Grow and Alga Bloom work perfectly well on 100% TERRA substrates. But Lightmix is not organic and doesn't contain soil life.
  4. When can I plant my seedlings in Lightmix?

    A seedling of 1-2 weeks old is ready to be planted in Lightmix.
