4+1 Compost Blend (Insect Frass - Rock Minerals + More - 8L / 27L)

A living mix of cow manure, chicken manure, mushroom compost, insect frass, and a rock mineral blend with 25+ trace elements.

The “4” = four composts (cow, chicken, mushroom, frass). The “+1” = the rock minerals added for trace nutrition.

Common sizes include 8 L and 27 L. Check the product page for current pricing and stock.

Yep. It’s alive by design. You may spot worms, worm eggs, white fungal threads (mycelium), or harmless crawlies. That’s normal and a good sign.

Blend 15–25% by volume into your potting mix. Example: for 40 L of mix, add 6–10 L of 4+1.

Add about 1 cm of 4+1 across the surface and water in immediately. Reapply monthly.

Yes—start with a light top-dress and water in. If you’re unsure on rates for your soil, test a small section first and observe.

Anytime: bed prep, at planting, and as a monthly top-dress. It feeds slowly and boosts biology across all stages.

Go gentle. Mix it into your base potting mix rather than planting ultra-young seedlings straight into a heavy layer of compost.

Supercharges microbial activity, adds slow-release nutrition, supplies 25+ trace elements, and improves moisture retention and soil structure.

The insect frass brings chitin, which can help prime plants’ natural defence responses. Think resilience, not a pesticide.

It’s a gentle, slow-release amendment, but you can overdo any input. Follow the rates and avoid packing raw compost tightly against delicate roots.

Keep sealed, dry, and out of direct sun. Because it’s alive, avoid extreme heat and heavy moisture.

Mostly an earthy, composty note—nothing harsh.

Yes—family- and pet-friendly when used as directed. Avoid creating dust and wash hands after handling.

That’s beneficial microbial growth (mycelium). It’s part of the living biology you want.

Nope. That’s normal in a living compost blend.

Common causes: too much compost piled on roots, over-watering, pH drift, poor drainage, or a deficiency your compost alone didn’t solve. Lightly loosen the top layer, improve drainage, and check moisture/pH.

Any moist organic mix can, especially if over-watered. Let the top few centimetres dry between waterings, use a thin mineral top-dress or mulch, and pop in sticky traps if needed.

It’s a complete, living amendment: multiple composts for biology + rock minerals for trace nutrition. More than “bulk”—it’s designed to elevate potting mixes.

You can, but scale salts back to avoid over-feeding. Many growers find they can reduce synthetics when running a living-soil approach.

Best in soil and soil-based mixes. In pure coco or hydro, particulates can clog lines and release can be inconsistent—use with care or stick to liquids in reservoirs.
