ABG mix is one of the most trusted substrates in the tarantula hobby, and for good reason. It holds a burrow shape well, drains excess moisture, and keeps humidity stable without turning swampy. This blend includes peat, orchid bark, sphagnum moss, charcoal, and tree fern fibre, mixed to a ratio most specifically for fossorial or terrestrial spiders.
 
Each 5L bag is ready to use straight out of the bag. Works great for New World and Old World tarantulas alike, and just as well in bioactive builds for other inverts.
