GRO-DIRT Guerrilla – Organic Living Soil

Size
$40.00
Description

GRO-DIRT Guerrilla is a rugged, 100% organic living soil engineered for high-performance cultivation in extreme outdoor conditions. Formulated to retain moisture through drought while draining freely during rains, it’s ideal for remote grows, arid zones, and locations with infrequent access. Built around ShrooM-PowR™ probiotic mushroom compost—chem-free, microbially inoculated, and aged for a year—this heavy-duty blend integrates high-grade peat, biochar, volcanic rock, zeolite, and a fortified mineral profile. Enhanced with endo/ecto mycorrhizae, Trichoderma, and 16-strain probiotics, it delivers long-lasting nutrition, rhizosphere stability, and consistent yields—no feeding required.

Soil people, same as you.

Soil Supply Co. started because we got sick of paying premiums for inputs that under-delivered. If we wouldn't put it in our own soil, it's not on the shelf.
