Josh’s Frogs ABG Mix is the perfect blend for growing tropical plants both in the home and in bioactive vivariums. Our mix is the original ABG Mix developed by the Atlanta Botanical Garden. Each bag is a precise mixture of charcoal, milled sphagnum moss, fir bark, tree fern, and peat. The mixture creates the perfect balance between retaining moisture and proper drainage; it can last for several years if used properly! <br><br> This substrate mix is for most applications when growing tropical plants, in a dart frog vivarium, paludariums, live plant terrarium, growing tropical houseplants, etc. <br> <br> <b>How to Use:</b> Pre mix the bag before adding the ABG Mix to the terrarium. Also, wet the substrate before using it for cleaner moving, the moisture helps cut down on dust. <br> <br> When using in a vivarium with a false bottom, make sure that the water in the bottom never rises up past the substrate barrier and ABG mix, as this will quickly result in a saturated, sopping wet mess that is unhealthy both for plants and animals. Anerobic bacteria can quickly take hold in these conditions. <br> <br> <b>How much is needed?</b> All measurements call for a 1"-3" layer of ABG. <br> Tank Size | Quarts ABG (4 Quarts = 1 Bag) <br> 10 Gallon Vertical | 4 <br> 10 Gallon Horizontal | 8 <br> 12x12x12 Exo Terra Glass Terrarium| 4 <br> 12x12x18 Exo Terra Glass Terrarium| 4 <br> 20 Gallon High Vertical | 8 <br> 20 Gallon Long Vertical | 4 <br> 20 Gallon High Horizontal | 8 <br> 20 Gallon Long Horizontal | 12 <br> 29 Gallon Horizontal | 12 <br> 18x18x18 Exo Terra Glass Terrarium| 8 <br> 18x18x24 Exo Terra Glass Terrarium| 8 <br> 24x18x18 Exo Terra Glass Terrarium| 16 <br> 24x18x24 Exo Terra Glass Terrarium| 16 <br> 24x18x36 Exo Terra Glass Terrarium| 16 <br> 40 Gallon Breeder | 16 <br> 36x18x18 Exo Terra Glass Terrarium| 16 <br> 36x18x24 Exo Terra Glass Terrarium| 16 <br> 36x18x36 Exo Terra Glass Terrarium| 16 <br> 55 Gallon| 16 <br> 75 Gallon | 20
