Get it right from the start—how much coco coir or peat moss you need for smooth, odor-free performance every time.
When it comes to composting toilets, the right amount of compost medium is the difference between clean, efficient performance and a frustrating mess. Whether you're using the OGO™ ORIGIN or the NOMAD by OGO™, dialing in your compost medium is key to keeping your setup simple, sanitary, and low-maintenance.
OGO™ ORIGIN: Built for Capacity, Tuned for Efficiency
For the ORIGIN, the sweet spot is 24 oz. of dry coco coir or sphagnum peat moss. This amount provides the right depth and density for solids to be effectively mixed by the internal electric agitator.
-
Dry vs. Moist:
While dry coir gives you more uses between cleanouts, it’s not always ideal on its own.-
Pros of dry: Maximizes capacity and helps reduce early saturation.
-
Cons of dry: Toilet paper breaks down slower, and super-dry coir can produce dust that affects air quality and mixing consistency.
-
Our recommendation: Slightly moisten the coir. Not wet—just enough to reduce dust and help paper break down more evenly. Think damp sponge, not soggy soil.
-
When to add: Add your medium after each full emptying of the solids bin. That 24 oz. will typically get you 25–30 uses per cycle.
NOMAD by OGO™: Simplicity, One Layer at a Time
The NOMAD system is manually layered—no electric mixing, just a smart sequence of compost medium and waste. For this setup:
-
One 24 oz. bag of compost medium gets you about 8–10 uses, depending on how consistently you layer.
-
Layering instructions:
-
Start with a fresh compostable bag and a base layer of compost medium.
-
After each use, add a small scoop of medium to cover waste.
-
Repeat until the bag is about ⅔ full.
-
Tie off the bag and discard responsibly.
-
This method is low-tech, low-maintenance, and ideal for weekenders, emergency kits, and compact mobile setups. The key to success? Consistency. If you skip layering or overload the bag, you’ll cut capacity and invite odor.
Where to Get Compost Medium
We make it easy—OGO™ offers 24 oz. pre-moistened coco coir bags for quick, mess-free use. Just open, pour, and go.
Prefer to source your own? Any dehydrated coco coir brick will work, and they’re easy to find at most garden centers or home improvement stores. Just rehydrate before use and break apart any clumps.
What If You Use Too Much?
Too much compost medium can clog the agitator in electric models or reduce capacity in bag-based systems. It’s tempting to overfill "just in case," but trust the process—less is more when the medium is right.
Final Thought
Compost medium isn’t just filler—it’s the engine behind odor control, composting efficiency, and clean-out simplicity. Whether you're living full-time in an RV with the ORIGIN or car camping with the NOMAD, a little knowledge (and 24 oz.) goes a long way.
Smart medium management = clean, stress-free performance. Every time.
