Fine, primarily peat-based mix. This is the "HP", or High Porosity formula for increased aeration and less water retention. This media can be combined with other ingredients such as fir bark, diatomite, perlite, etc. to create an endless variety of unique mixes to suit any need. Great for use with terrestrials.
Please Note: Be sure to watch your watering as too much water can easily cause the medium to stay too wet.
