Shaped like mini greenhouses, garden windows feature an extended box shape that lets light in from all sides, including the top. The left and right side windows open and close easily with casement-style cranks, allowing you to let in plenty of ventilation when needed, while locking securely in place when not in use. A tempered glass shelf gives you two levels on which to grown an indoor herb garden, or house other sun-loving plants, or feature your favorite picture frames and other decorative items.
