Mycotrex is a mixture of endo-mycorrhizal spores, rhizosphere bacillus, seaweed meal and humic acids, which improves absorption of nutrients and water, increasing the rooting capacity of marijuana plants up to 700%.

The growing media should not contain pathogens or weed seeds. For this reason, most soils are sterilized with steam, which also kills beneficial bacillus and mycorrhizae. Plants will be very vulnerable during their life due to the the loss of these bacteria.
