Cow – Chicken – Mushroom – Insect Frass – Rock Minerals

Our new compost blend has been designed to help gardeners build premium potting soils add back valuable nutrients to existing garden beds!

We’ve sourced the highest quality components, removed all the unwanted clumps, & blended in our in-house Rock Mineral Blend consisting of over 25 trace elements.

Nutrient-dense Cow & Chicken manure, along with our unique blend of mushroom compost (consisting of both traditional & hardwood grown varieties), make up the base of this blend. We then fortify the mix with 100% organic Insect Frass & Rock Minerals for strong, healthy growth.

This mix contains on average 300,000 active colony-forming units of beneficial soil microbes per gram of compost. If you notice any white, microbial growth inside the bag - it's the good stuff!

How to use

Mix in 15-25% by volume into new potting mixes.

For existing potted plants, add 1cm of 4in1 to the soil surface and water in immediately. Reapply monthly.

Please note, this is a living biological product. You will from time to time, find worms, worm eggs, and the occasional benign "creepy crawly" in this blend.

Great products

Good old fashioned service

Great Quality Compost

Great compost, have used it in multiple grow cycles in my living soil and it only seems to be getting better each round.

First poor review

Been a customer for 12 to 18 months and has all been 5 star reviews but unfortunately not this time. Firstly the 2 27l bags came with a lot of fungus gnats and secondly was lashed on the samples for spending over $150 on both orders. They were showing in my cart and once I proceeded to checkout to pay they were removed saying out of stock

Morning Brad,

It's disappointing you didn't give me the opportunity to replace your items before leaving a public review. Up until last night your emails did not indicate any stress or disappointed mate, but your review suggests otherwise.

Just know, I do offer a money back guarantee if you bring me an issue and allow me to fix it.

Thanks Brad

Pretty good stuff

Has a nice arouma, and is a nice black colour. I think it works better for established plants. There is also a slight smell emitted from the potting mix. I think that the straight worm castings that it replaced actually was more effective. Perhaps my suggestion would be including this ingredient for greater effect.
Other than that very nice blend and creates luscious healthy plants.

Big thanks for sharing your thoughts with us mate. Finding just the right castings in the quantity we need is definitely a hard task!
