Adding greenery to your office is a great idea! For moderate light and low maintenance, consider snake plants, pothos, or peace lilies. These plants are known for their air-purifying qualities. Snake plants and peace lilies, for instance, can help improve air quality by removing toxins like formaldehyde. As for boosting mood and productivity, plants in general have been shown to enhance these aspects.
For arranging them, try placing a taller plant like a snake plant in a corner, while smaller ones like pothos can be hung or placed at eye level on shelves or desks. This setup not only saves space but also draws the eye around the room, creating a more inviting atmosphere. Have you thought about using plant stands or wall-mounted planters to save desk space?
