A terrarium is a collection of small, decorative plants growing in an enclosed environment.
Terrarium will mostly benefit from the natural bright light that comes from natural filtered sunlight. If for any reason your room is too dark, you can use artificial fluorescent lighting for plants. Southern sunspots in a house will receive the best amount of bright light during the day.
Avoid light and heat extremes and don’t overwater, and you won’t have an issue with humidity. Misting is sometimes recommended to keep the plants moist, but it’s not always necessary. It can minimize the need for watering but doesn’t replace it.
