PRO-MIX HPO BIOFUNGICIDE + MYCORRHIZAE is a peat-based substrate formulated for high-quality performance with enhanced disease protection. It’s made without perlite, containing a denser structure that gives growers more control over drainage and moisture retention — meaning it’s especially beneficial for dialed-in irrigation systems. It features MYCORRHIZAE (Glomus intraradices) to enhance root development and nutrient uptake, as well as a biological fungicide (Bacillus pumilus) that helps suppress root pathogens that contribute to disease. It delivers a cleaner root zone, stronger plant resistance, and consistent growth from veg to flower — making it a great choice for organic-minded growers or those running sensitive genetics that require extra protection against rootborne issues. If you’re looking for a similar formulation with OMRI-listed ingredients, look into PRO-MIX MP MYCORRHIZAE ORGANIK. For growers focused on a lighter, more aerated mix with a biostimulant, PRO-MIX HP BIOSTIMULANT + MYCORRHIZAE is a solid alternative.
