Our designs are hand-crafted using a variety of sustainably sourced moss. All of the the moss (& plants) we use are real. They have been preserved with a non-toxic, food grade glycerin process. Our biophilic art does not require any maintenance, watering or misting. Our preserved biophilic designs do not contain any soil. Your moss art will adapt to the condition and humidity of your space. To keep your moss soft and pliable, the optimal humidity of your space should be above 30%. The average humidity in a home is 50%.  Your moss may become firm or hard to the touch if the humidity drops below 30%. As the humidity increases your moss will become soft and supple again. Do not water or mist.
