PRO-MIX MP MYCORHIZAE ORGANIK does have a starter fertilizer charge which contains Sustane 4-6-4 plus humates, and also seaweed granules. The fertilizer charge will last from 2 to 4 weeks. 2 weeks in the summer
and 4 weeks in the winter months.
But we do recommend starting fertilization before that fertilizer charge runs out so that there’s time for the natural microorganisms to break the fertilizer down so
it can be used by plants.
