DIY Mini Greenhouses from 5L Plastic Bottles for Growing Greens at Home

share 42

Growing your own greens at home is not only a sustainable and budget-friendly option, but it also allows you to enjoy fresh and organic produce right at your fingertips. One creative and eco-friendly way to do this is by crafting your very own mini greenhouses from 5-liter plastic bottles. In this DIY guide, we’ll walk you through the steps to create your very own mini greenhouse using this inventive method. These mini greenhouses are perfect for small spaces, patios, balconies, or windowsills, enabling you to cultivate greens all year round.


  1. 5-liter plastic bottles
  2. A sharp knife or scissors
  3. Potting soil
  4. Seeds or seedlings of your chosen greens
  5. A marker
  6. Fasteners (like twist ties or rubber bands)
  7. Drainage holes (created with a nail or small drill)
  8. Gravel or small stones (for the bottom of the bottle)

Step 1: Preparing the Plastic Bottles

  • Begin by gathering clean and empty 5-liter plastic bottles. Make sure they are thoroughly rinsed and dried.
  • Using a marker, draw a triangle shape on one side of the bottle. The top tip of the triangle should remain uncut, serving as a hinge.
  • Carefully use a sharp knife or scissors to cut along the lines of the triangle, ensuring you leave the top tip uncut. This hinged section will be the “door” for accessing your mini greenhouse.

Step 2: Adding Proper Drainage

  • Create drainage holes at the bottom of the bottle using a nail or a small drill. These holes will allow excess water to escape, preventing waterlogged soil.
  • Add a layer of gravel or small stones at the bottom of the bottle. This will create a space for excess water to collect without saturating the soil.

Step 3: Planting Your Greens

  • Fill the bottom of the bottle with potting soil, leaving enough space at the top for your greens to grow.
  • Plant your chosen seeds or seedlings in the soil. Make sure to follow the planting instructions for the specific greens you’re growing, including spacing and watering requirements.

Step 4: Caring for Your Mini Greenhouse

  • Water your greens as needed, making sure not to overwater. The small space within the bottle will help retain moisture.
  • Place your mini greenhouse in a location that receives the right amount of sunlight for the type of greens you’re growing. Some greens prefer full sun, while others thrive in partial shade.
  • Keep an eye on the temperature inside the mini greenhouse. If it gets too hot, you can slightly open the “door” to allow for ventilation. If it’s too cold, keep the “door” closed to maintain warmth.

Step 5: Securing the Mini Greenhouse

  • Once your greens have started growing, use fasteners such as twist ties or rubber bands to secure the hinged “door” in a closed position.
  • This will create a greenhouse effect, trapping heat and moisture inside and providing an optimal environment for your greens to thrive.

Conclusion: Creating your DIY mini greenhouse from 5-liter plastic bottles with proper drainage is a fun and sustainable way to grow greens at home. Not only does it repurpose plastic bottles, but it also allows you to control the growing conditions for your greens, ensuring they receive the right amount of light, warmth, and humidity. So, give it a try and enjoy fresh, homegrown greens all year long while making a positive impact on the environment. Happy gardening!
