NEHERP Vivarium Substrate: Original
The original high performance store brand bioactive substrate mix
Our carefully proportioned substrate was designed to be the ideal blend for tropical live vivarium ecosystems ranging from 75-99% R/H. Having been in production since 2009, ours is the longest-running & most proven store brand substrate mix available for bio-active enclosures. Our substrate is packed with an appropriate quantity of aggregate ingredients which help it to to resist over-saturation and compaction, while remaining nice & airy long term. During product development, our goal was for NEHERP Substrate to support flourishing plant life, and foster healthy populations of microfauna, mycorrhizal fungi, and beneficial microbes. Each of these trophic layers of biological activity are necessary for the enclosed environment to function as desired once the primary inhabitant is introduced. We're proud to say that our substrate is used by zoos, museums, breeders, and enthusiasts all over the USA, and we're confident that it's the highest quality & best performing pre-mixed vivarium substrate on the market.

We're open & honest about what's in our substrate for a reason. Our ingredients are absolutely top of the line, and we don't skimp on any of the important stuff. We work directly with one of the last tree fern importers in the USA, and even mill our own from time to time to help keep up with demand. Our coconut fiber is sourced directly from a mainstream pet supply brand - not from a horticultural supplier whose less expensive product may have higher salinity. Same goes for the fir bark, which is specifically marked for use with Reptiles & Amphibians. Even the Sphagnum Moss is the same brand we carry separately, which is AAA-Grade New Zealand sourced product. The organic charcoal ingredient is a fine-milled natural hardwood product sourced from an American-based manufacturer. If you can think of a way to use higher quality ingredients, we'd sure love to hear how.
NEHERP Vivarium Substrate: Version 2
A Bioactive Substrate designed for a wider variety of environments
Our NEHERP V2 Vivarium Substrate Blend was specially designed for a wider humidity range than our tropical V1 mix. Thanks to a tweak in the (equally high quality) ingredients list, we're able to recommend this blend for live vivarium ecosystems ranging from 55-90% relative humidity. The wider range of acceptable conditions makes this our most versatile blend, and we've had success using it with everything ranging from Dart Frogs to Geckos. Having been tested & used consistently since 2012, this blend has been universally well received by a wide variety of enthusiast communities, and has even passed out our original substrate in popularity! When used as described in our VC101 & VC102 articles, this substrate will support plant life, as well as populations of microfauna, mycorrhizal fungi, and beneficial microbes with ease. We're proud to say that this blend is used by zoos, museums, nature centers, breeders, and hobbyists all over the USA! Read more...
Like all of our NEHERP substrates, this mix includes only the absolute highest-grade ingredients available. The coconut fiber, cypress mulch, and fir bark ingredients are all sourced from a mainstream pet supply brand which specifically manufacturers each for Reptile & Amphibian use. The Sphagnum is AAA-Grade New Zealand sourced product, and both the calcined clay & fine grade charcoal are sourced from a trusted US-based manufacturer. We're really proud of this mix, and we're confident you'll absolutely love it.
NEHERP Vivarium Substrate: ABG Mix
A mixture pioneered by the experts at Atlanta Botanical Gardens
Authentic ABG mix is often regarded as "industry standard" by enthusiasts, and has been a proven solution for vivarium substrate since long before NEHERP opened for business. In our experience, this blend is best for enclosures which will range from 75%-99% relative humidity. To ensure the best quality product for our customers, we use only the highest quality ingredients available in our ABG mix. Our Sphagnum moss is AAA grade from New Zealand, our peat moss is OMRI listed from Canada, and both our Fir Bark & Coconut Fiber ingredients are sourced from a pet supply brand. Tree fern is increasingly difficult to find nowadays, but we've secured a source & even periodically mill our own tree fern fiber out of raw tree fern in-house. Because it contains peat moss (which is hydrophobic), we strongly recommend pre-moistening this substrate by mixing water into it before using it in a vivarium. Read more...
Not all ABG Mix is the same. We stick closely to the original recipe (posted above), but it seems that the overwhelming majority of commercially available ABG Mix follows a different set of ingredients. Even with identical ratios, our ABG Mix is designed to stand out thanks to it's higher-grade of ingredients (described above). If you are shopping around for prices, please be sure to compare both ingredients and the grades of ingredients. We're proud to offer the best ABG mix available, and that's not a gimmick. In New Englander terms, "It's wicked good substrate!". With that said, both types of NEHERP Vivarium Substrate are actually higher in micronutrient contents, lower in acidity, and are also not hydrophobic. (Authentic ABG mix is awesome, but we like the performance of our NEHERP brand stuff even more!)
