Description from Moss Acres
Moss Acres offers a special kit containing three varieties of live moss for terrariums
For anyone considering starting their own indoor garden, a moss terrarium is ideal. Not only does moss provide soothing shades of green and incredibly eye-catching textures, it is also unbelievably low maintenance. Once watered thoroughly, the micro-landscape of an enclosed moss terrarium requires next to nothing other than adequate light to keep it flourishing even for months on end without watering. The moisture in the terrarium recyles as water vapor, returning regular moisture to the terrarium moss. (Scroll down to find terrarium supplier.)
Each terrarium kit includes three varieties of moss well suited for terrariums, and totaling one square foot (12″ x 12″). For larger terrariums, simply order additional kits, or one of our moss sampler sets. If you have any extra moss, simply plant it outside!
Moss is also the ideal companion plant for pet reptiles or amphibians.
