DIY plastic bottle greenhouse!

Are you looking for a way to have a small greenhouse in your yard to grow some veggies? Then why not try using plastic bottles to build one? Building your own greenhouse out of used plastic bottles is a great way to recycle and repurpose material that would otherwise end up in a landfill.

Not only is this a great way to be more eco-friendly, but it can also save you money on purchasing a traditional greenhouse or greenhouse materials. This project will teach you how to upcycle plastic bottles into something useful for growing food in your garden. This can be a fun project for the whole family.

Plus, it’s a great way to get started with gardening and learn about how plants grow. Not only are you keeping construction expenses to a minimum, but you are also helping save the environment.

To build a large-sized plastic bottle greenhouse, you’ll need around 1,500 pieces of 2-litre plastic bottles. Can you imagine how much waste you’re already keeping away from nature with just a single greenhouse project? Not to mention, you’ll be doing your part to combat climate change.

Building a plastic bottle greenhouse is a great way to reduce your carbon footprint and help the environment. And you’ll get to enjoy fresh fruits and vegetables year-round. So, what are you waiting for? Start your project today! It indeed is a great recycling idea for plastic bottles!

Plastic Bottle Greenhouse

Now it might not look like a robust and effective structure to some, but many DIY-ers have already built their own plastic bottle greenhouse. Despite its humble appearance, a plastic bottle greenhouse can be a surprisingly solid and effective structure, as many DIY-ers have already discovered.

  • Garden Canes
  • Cement Mix

Steps to make a DIY Plastic Bottle Greenhouse:

(1) Gathering Plastic Bottles

While it may take some time to gather a large number of plastic bottles, it will be well worth the effort in the end. Be sure to collect bottles that are all the same size for this project, as it will make the process much easier.

(2) Clean the Plastic Bottles

In order to recycle plastic bottles for use in your greenhouse, you will need to clean each bottle thoroughly. This will ensure that your greenhouse is free from dirt, grime, and other contaminants that could potentially harm your plants.

You can clean the bottles by using a mild soap and water solution, or by using a commercial cleaner specifically designed for plastic. Once the bottles are clean, you can then proceed with using them in your greenhouse.

(3) Build the Posts

Building the posts for your plastic bottle greenhouse is a simple process that can be completed using 4 x 4 treated lumber. The first step is to cut the lumber to the desired height, keeping in mind that the posts will need to be tall enough to support the weight of the greenhouse.

(4) Make a frame for each part of the greenhouse

You should then make a frame for the door, the sides and even the roof of your plastic bottle greenhouse. This will help to support the structure and keep it from collapsing. You can use any type of material for the frame, but make sure that it is sturdy and will not rot.

(5) Stacking the plastic bottles

Since you have cleaned the bottles, use a saw drill to make a hole at the bottom of each bottle. Make sure to use a saw drill with the same diameter as the garden canes, so that the canes can go through each bottle when stacking them. The garden cane will make the structure sturdy.

You can stack five (5) or more plastic bottles through the garden cane depending on your desired height for your plastic bottle greenhouse. You can also use different colours of bottles to create a more aesthetically pleasing design.

(6) Assembling the parts of the plastic bottle greenhouse

To assemble your plastic bottle greenhouse, start by attaching each end of the canes to the frames of the parts you made earlier. You can do this by using fencing staples. Make sure the canes are securely fastened so that they won’t come loose over time.

Assemble the parts(the sides, the door, and the windows if you want to) together to the post. Finally, put the roof on your greenhouse and secure it in place. Make sure the roof is secure so that it won’t blow away.
