This is a selection of our range of organic dry amendments that have a low NPK value but are full of minerals, trace elements and enzymes for your substrate. These can be used with both photo or auto varieties. Each has its own unique benefits, for instance we recommend adding Wormcasts for boosting the humus levels in your substrate, or Barley for enzymes that turbo charge nutrient absorption or MycoBoost for a cal mag and beneficial bacteria top up.
