Classic Terrarium Base Mixture Recipe
In the world of terrarium and vivarium horticulture, the Arnold, Bennett, and Garner (ABG) mix has long been a popular choice due to its excellent drainage, water retention, and nutrient retention properties. Originally developed by the Atlanta Botanical Gardens, the ABG mix includes key ingredients like Sphagnum Moss, Tree Fern Fiber, Orchid Bark, Peat Moss, and Charcoal in specific ratios.
However, as concerns about sustainability and accessibility grow, alternative options are emerging. These substitutes not only ensure a balance of drainage, moisture retention, and organic material for microfauna but also prioritise environmentally friendly components.
One such alternative is a mix of play sand and ReptiSoil, which offers a substrate base that mimics the drainage and moisture retention qualities of the ABG mix. This combination, consisting of approximately 70% play sand and 30% ReptiSoil, can be a viable option, especially in regions where traditional ABG components are scarce or ecologically problematic to harvest.
Coconut fiber, or coir, is another sustainable and renewable resource that can replace peat moss components of the substrate. A blend involving coconut fiber, sphagnum moss, orchid bark, and activated charcoal can serve as a well-draining and moisture-retentive base for bioactive setups.
Local leaf litter and bark can also be used instead of imported materials like oak leaf litter or cottonwood bark. This approach supports the microfauna and maintains natural decomposition processes, enhancing sustainability and availability.
Incorporating live cultures such as isopods and springtails, which thrive on decaying leaf litter and organic waste, complements the substrate and reduces the need for chemical or synthetic additives, supporting a natural ecosystem.
Premium long-fiber sphagnum moss, tree fern fiber sourced from various tree fern species, and orchid bark are still key ingredients in these alternatives, providing essential drainage and aeration. Coconut coir, with its excellent water retention properties and stability, can be a good substitute for peat moss. Horticultural charcoal and activated charcoal remain the best choices for filtration.
While these alternatives may significantly change the consistency of the ABG mix, they offer a more sustainable and accessible choice for terrarium enthusiasts. These options can be purchased on platforms such as Etsy or alternative marketplaces, and there are also variations available on the market.
By choosing these alternatives, terrarium hobbyists can continue to enjoy the benefits of the ABG mix while contributing to a more sustainable and environmentally friendly horticulture industry.

- In the realm of terrarium and vivarium horticulture, sustainable alternatives to the traditional ABG mix are known for their capacity to balance drainage, moisture retention, and organic material for microfauna, while prioritizing environmentally friendly components.
- For instance, a mix of play sand and ReptiSoil can offer a substrate base similar to the ABG mix, consisting of about 70% play sand and 30% ReptiSoil, serving as a viable option in regions where traditional ABG components may be scarce or ecologically problematic to harvest.
- Meanwhile, coconut fiber, or coir, can be another sustainable and renewable resource that can replace peat moss components of the substrate, forming a well-draining and moisture-retentive base for bioactive setups.
