GRO-DIRT Organic Living Soils

Close-up of microbially charged GRO-DIRT.

Water-only, seed to harvest. Hand-mixed on the NSW Mid-North Coast.

The premium solution for organic growing

GRO-DIRT is a complete biological growing system. Every blend is built on a custom microbial compost base, mineral-charged, and pre-inoculated with fungi and bacteria we culture in our own lab. Plant into it, water it, and the soil does the feeding.

The four blends

Full Spectrum — the complete water-only build. Cutting to harvest, no bottled schedule. Guerrilla — engineered for open ground and drought pressure. Lite — a lighter charge for clones and early veg, or for growers who prefer to steer with their own inputs. Super Starter — fine-structured and low-salt, built for seeds and clones to root into.

What's actually in it

Mycorrhizal fungi, Trichoderma and nitrogen-fixing bacteria established through the mix, not dusted on top. Humic-rich compost aged in-house. Volcanic minerals and rare marine inputs from suppliers most soil companies never get access to. No synthetic fillers, no chemical salts, no wetting agents.

Why it costs what it costs

GRO-DIRT is the premium option and that is deliberate. The ingredient list is missing cheap bulking agents and is full of materials that are difficult to source and costly to hold. It is also an asset rather than a consumable — recharged between runs, a living soil bed improves with every cycle. No bag of potting mix will ever do that.
