In a context in which the recycling and conservation of the environment are at the center of concerns, Use plastic bottles to prepare a greenhouse It has proven largely. In addition to being an alternative at affordable prices for amateur or confirmed gardeners, the construction of a greenhouse in plastic bottles allows you to combine ecology and practicality.
The concept of greenhouse in plastic bottles
As the name suggests, it is about replacing the traditional glass panels of a greenhouse with plastic bottles in order to create a modular structure at a lower cost, while contributing to the recycling of waste. In fact, they offer excellent thermal insulation, which guarantees Optimal growth plants in ideal conditions.
The interest of plastic in the construction of the greenhouse
Plastic bottles have several advantages for the creation of a greenhouse:
- Unmperie resistance: Plastic is less fragile than the glass and is not afraid of the temperature shocks or other inconveniences related to the climate.
- Transparency: By opting transparent bottles, maximize the «greenhouse» effect and then guarantee a good growth of your plants.
- Modularity: The combination of plastic bottles allows you to imagine a customized structure, adaptable to the size of your garden and your needs.
- Cost : Finally, the greatest advantage lies in the free recovery of the bottles, making the construction of the greenhouse very cheap.
In addition to its economic advantages, this modular structure contributes to the recycling of waste while guaranteeing excellent thermal insulation to promote optimal growth of plants in ideal conditions.
Find out how to transform a simple bottle into a practical and cheap mini-bristle, ideal for growing your plants and your sowing, even in the smallest spaces.
Key steps to build the greenhouse in plastic bottles
1. Bottle collection
The first step in this project is to bring together a large number of plastic bottles. To do this, you can request those who surround you or recover those who will not fail to accumulate during the parties and other events. Make sure you choose transparent or even slightly colorful bottles if you want to add a touch of color to the greenhouse.
2. The preparation of bottles
The next step is to prepare the bottles for their integration in the greenhouse structure. Start rinsing them carefully to get rid of any residue.
Then remove the labels and separate the traffic jams. It is important to ensure that all bottles have the same shape and the same height.
The concept of greenhouse greenhouse offers a brilliant solution for external development by replacing traditional glass panels with plastic bottles.
3. Bottle assembly
To make the structure of the greenhouse, you will have to assemble the bottles with each other. For this, two options are available:
- Dip the bottles on top of the other by connecting the collar with a piece of flexible tube. Make sure to orient them in the same direction and to seal them well to avoid any air loss.
- Practice holes on the bottom to slide them on a metal or wooden frame. This solution offers more stability and makes it easier to obtain a rectangular structure.
4. The construction of the structure
Once you have assembled enough bottles to build plastic walls, you can start drawing the shape of the greenhouse. Do not hesitate to draw inspiration from the existing models or even to create an original structure based on the wishes and constraints of the garden.
To build this structure, you will need a solid frame to support the weight of plastic bottles. It is possible to use wood (slats, axes or pickets)steel or pvc pipes.
Make sure to safely correct each line of bottles on the frame, while be careful to leave enough space for the openings (door, windows).

Faced with the constraints of the greenhouse in plastic bottles
Watering of plants
As with any estate, theWatering of plants It is a key element for their good development. To preserve the water and avoid too large a humidity inside the greenhouse in plastic bottles, it is recommended to install a drop irrigation system.
Maintain a good temperature in the greenhouse
The main advantage of a greenhouse is to provide plants with a protected area of bad weather and temperature variations. To maximize this effect, make sure that the greenhouse of the plastic bottle is well exposed to the sun and that it has good air circulation through the openings.
Protect your plants from parasites
Finally, although plastic bottles are an effective barrier against some insects, it may be necessary to use the forced veil or other natural methods to protect plants from parasites and diseases that can be used in the greenhouse in plastic bottles.
In conclusion, the performance of a greenhouse in plastic bottles is a project accessible to all gardeners who wish to benefit from an ecological and economic greenhouse, contributing to the reduction of plastic waste.
