MycoBoost is a unique blend of mycorrhizal fungi, plant beneficial bacteria, humic, fulvic and amino acids and organic growth stimulants. An ideal dry amendment or foliar spray to boost microbial activity and provide secondary macronutrients (including calcium and magnesium) plus valuable trace elements to your substrate.

It compliments all our other dry amendments and can be used at any stage of the plant’s lifecycle: it has been found to be particularly useful in flower alongside Bloom, Bloom2 (or Bloom AUTO) and Barley as a result of the increased phosphorous uptake and brilliant when growing in coco for an additional cal mag top up.
