Keep your terrarium in a bright room, north facing window is best.
If it is a hot day draw the blinds so the leaves do not get sun burnt during the heat of the day. Also take the lid off for 5min to allow it to breathe. Mist it lightly with fresh water before placing the lid back on.
Trim any dead leaves or remove them from the ground.
If your terrarium has no lid water it with a mister daily or pour water weekly (use a shot glass).
It's ok if little white bugs live in there, they are helping break down all the dead roots and leaves. If they were not in there you would have mould. and yuck!
