GRO-DIRT Super Starter – Organic Living Soil

Size
$35.00
Description

GRO-DIRT Super Starter is a premium organic living soil blend engineered for explosive root growth and early vigour in seeds and clones. Developed through extensive testing, it combines a finely tuned aerated base with biodynamic compost, vermicast, humic-rich biochar, and high-paramagnetic basalt, creating an ideal environment for stable temperature, moisture retention, and early microbial colonisation. Inoculated with endo/ecto mycorrhizae, Trichoderma, and root-stimulating microbes, it delivers a biologically active foundation without synthetic fertilisers, just water required. Perfect for propagation trays, seedling pots, or direct sowing, it supports a seamless start and primes young plants for high-performance growth.

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.
