19. The CD Case Greenhouse
With the rise of digital music, many of us have stacks of old plastic CD cases taking up space in storage. You can upcycle these clear plastic squares into a miniature, fully functioning tabletop greenhouse. This eco-friendly project is perfect for starting seeds, propagating cuttings, or housing moisture-loving succulents and air plants.
To build this mini greenhouse, arrange the CD cases into a house-like structure with four walls and a pitched roof. Use a strong, clear-drying plastic adhesive or a hot glue gun to secure the cases together at the seams. Because the plastic is clear, it allows maximum sunlight to reach your plants while trapping humidity and warmth inside, creating the perfect microclimate for young seedlings. This clever project turns plastic waste into a beautiful, life-giving garden accessory.
