What is in every drum
Brewed from castings, checked under the microscope.
High quality worm castings go through a proprietary brew that multiplies the biology rather than draining it off. Every batch is analysed before it leaves Gin Gin.
- Independent DNA testing confirmed the highest bacterial and fungal diversity on the market
- Nitrogen-fixing microbes carrying over 14,000 ppm of nitrogen
- Up to 80 chelated minerals, carried into the produce
- Filtered to 400 microns so it runs through booms, drip lines and watering cans
Delivery in 5 to 10 working days

Buying questions
Sizes, shipping and which drum.
Think of Plus as WormGro that went to agricultural college. Same million-plus microbial species, with a balanced 10:10:10 NPK added for crops that need immediate major nutrients. Because the microbes chelate those nutrients, nearly all of it reaches the plant instead of leaching or volatilising.
Balance is the hybrid: a full spectrum of major and minor minerals (N 5, P 2, K 0.5, calcium 6.8%, magnesium 1.2% and the traces) blended with worm cast from native and compost worms, sea minerals, humic and fulvic acid, seaweed and molasses. It is built for cutting back on synthetics, and batches can be brewed to a soil test.
A 1L bottle covers about 500 square metres of garden per application. A 20L drum of WormGro covers about 4 hectares of pasture. Broadacre programs run on 200L drums and 1000L shuttles, which are the cheapest per litre: WormGro is $4.78 a litre by the shuttle against $13.40 a litre in a 5L drum.
Order online, or call George on 0427 573 424 and he will put it through for you. Bulk and shuttle orders usually start with a quick conversation about the crop so the rate and the size match.
1L packs ship express for free anywhere in Australia. Drums and shuttles deliver in 5 to 10 working days; 1000L shuttles freight at a $500 flat rate to NSW, Victoria and Queensland. Ask us about other states before you order a shuttle.
Twelve to twenty-four months depending on storage. Keep it cool and shaded, never frozen, and stir before use. The microbes are alive, which is also why the drum has a healthy ammonia smell when you open it.
