Shari Petrucci from the Western Mass Masters Gardeners Association shares a suggestion at Mass Appeal:
"If your air-plants are in a small terrarium and you are unable to remove them for watering, we recommend misting them through the opening once weekly. This method can also be used for our hanging globe terrariums, wall pockets, and apothecary terrariums. Pay close attention that your plants are getting adequate moisture, but are not sitting in water within any terrarium."Remember that using distilled water in terrariums can reduce the amount of mineral deposits that develop on the glass.
