If you wish to make a more positive mark on the environment you can accomplish this goal by utilizing plastic bottles in afun and innovative way. A plastic bottle greenhouse is one of the largest use for the waste plastic bottles that you might end up throwing away. Organize a drive to collect waste bottles from your community once you have made your mind up for such a project. Before you begin, estimate the size of the greenhouse that you are intending to build so you can collect sufficient bottles. Remember that creating something as big as this will be a laborious and time-consuming task.
Advantages of building a greenhouse out of plastic bottles
This is the cheapest and most reasonable way to reuse plastic bottles that are lying to be thrown away with your trash. To build a greenhouse of dimensions 8×6” you will need approximately 1400 2-liter bottles, which you can collect from your family, friends, and neighbors. Plastic bottles can raise the temperature to 10 degrees higherthan the external climate, allowing longer growing seasons for plants irrespective of the external environment.
Such a greenhouse is also easier to repair because each bottle is independent of the other, any broken or damaged bottle can be pulled out and replaced. Another advantage of using plastic bottles is their strong ability to withstand strong winds. If the lines of the bottles are anchored properly, the architecture will be sturdy all year long.
Building your own Greenhouse out of plastic water bottles
- Preparing the bottles
Clean the collected bottles thoroughly to remove the labels and also clean all the dirt. This can be done by using soapy water and some buckets full of clean water. Try to avoid water wastage during this process. With a pair of sharp scissors, remove the top and the bottom of the cleaned bottles. This process has to be performed with caution as the scissors and the cut plastic can be sharp and induce cuts if not handled properly. If you have kids helping you in the project, supervise them during this entire process.
- Fixing the posts and building the basic frame
Fix four vertical posts for the corners of your greenhouse into the land. You can use 4×4” treated posts and cement them a couple of feet below the ground level. Add slabs or mulch around the inside to avoid growth of weed. These posts will function as the corners of your greenhouse. You can use 2×2” timber to make a basic framework for the project. Create the door and the roof using these timber frames that have mitered corners screwed together.
- Threading the bottles
Start stacking the bottles one inside another with the bamboo canes supporting them in the middle. Reverse a bottle on one end so that it locks the others. When you are done threading the bottles you will have a long line of bottles one inside the other with the ends of the cane sticking out on either side.
- Attaching the stacks on the frame
Start placing the stacks of bottles next to each other on the frames that you have made for the walls. The canes that are sticking out of the top and bottom of these stacks will be attached to the top and bottom timber of the frame by using fencing staples.
Staple as many rows as possible to completely fill the frame with rows of bottles. For the roof, you can use two triangular frames made out of timer if you choose to make a sloping frame or a simple frame for a flat roof. Prepare these frames in an identical manner
- Putting it all together
Start screwing the prepared frames to the uprights that you cemented earlier. You can prepare a door in the similar fashion but remember to keep it slightly smaller than the inside of the frame that you have prepared for free opening. Now that you are done, start planting your veggies and flowers in your recycled greenhouse.
A greenhouse in your backyard is an ideal way of saying that you are pro-environment. Building one yourself with the use of recycled plastic bottles can be the biggest motivating statement that you make in the world.
