This is for 1 gallon of substrate.

ABG needs to be moistened before it is placed in a terrarium.  The bag should be emptied into a container and have water mixed into the substrate mix until it is evenly moistened.

Typically when used in terrariums, one to two inches of substrate is adequate for most microfauna and plants.  You may want to use additional substrate to build your landscape and hardscape, but it is not required for good plant growth or success with most microfauna.
