How to Build a Greenhouse Made From Plastic Bottles

Updated on March 31, 2018

Here is a step-by-step guide on how to build a plastic bottle greenhouse, for those of you with the time and patience to collect enough empty plastic bottles to construct one.

Making this type of greenhouse is cheap, but it is also quite an undertaking in terms of labour and the time it will take. Perhaps it is best left to community organisations and schools, you might think.

Don't let that put you off. There is no reason why everyone should not have such a wonderful PET plastic construction in their yard.

PET stands for Polyethylene terephthalate which is the type of plastic approved worldwide for plastic bottles intended for the drinks industry.

Advantages of a Plastic Bottle Greenhouse

  • It's cheap to construct. You will need approximately 1400 empty 2 litre (40oz) plastic bottles to build a greenhouse that is 8' x 6'. Even if you don't use that many, you can collect them from neighbours, friends, hotels, bars, and restaurants in your area.
  • It is self-watering. Because there are gaps at the tops of the bottles, heavy rain can certainly penetrate from where the bottles lie side-by-side. This is a huge time saver for greenhouse growers. Also, rainwater is always better for your plants than tap water.
  • It raises the temperature. The temperature is raised about 10 degrees centigrade compared to the weather outside. That is a huge difference and it should certainly lengthen the growing season for many plants, no matter what climate you live in.
  • It saves landfill sites from yet more plastic waste. It goes without saying that if everyone saved those plastic PET bottles for constructions like greenhouses, there would be less to clutter up landfill sites.
  • It is cheap and easy to repair. You can simply replace the plastic bottle that has broken or been damaged by missiles or animals. All your bottles are hooked onto either wire or a cane or sticks. So all you need to do is unhook the line, slide out the bottles including the broken one(s), and replace it with a fresh one.
  • It is sturdy and can withstand strong winds. Plastic bottles can't get blown away when they are pinned into place. The strength of your structure will depend entirely on how well the lines of bottles are anchored.

How to Build a Plastic Bottle Greenhouse

  1. The bottles are washed to remove labels, then the bottoms are cut off. You will need to remove the bottle lids too.
  2. Thread your bottles through whatever medium you choose to use to hold them in a line. This can be bamboo canes, or lengths of stick — though they need to be slim enough to feed through the bottle opening — or wire.
  3. Once you have your basic frame, you then connect your canes or sticks with the interlocked plastic bottles already fitted, to the frame.
  • All the greenhouses I have seen built with plastic PET bottles have used a wooden frame, which is surprisingly not terribly 'green' as trees have to be cut down to provide the frame. It also requires constructing, and that would mean calling in a joiner or woodworker in my case anyway. I am still thinking of alternatives to wood.

An Alternative

Another way to build your greenhouse would be to interlock all the plastic bottles together, one on top of the other, as above, with the bottoms cut out to make a tighter fit, but without a central support. Instead, horizontal wires can be attached both inside and outside the greenhouse to hold the bottles in position, as shown in the photo below.

You will note that, in this project, the lids were left on the bottles, and I must admit I quite like that idea as it is one less place for insects to enter and make themselves at home.

Can you imagine how horrible going into your new plastic bottle greenhouse would be if you were confronted every time by nests of insects in the walls? Apart from the aesthetic appearance, a good deal of light would be cut out.

As Insulation

Plastic bottles greenhouses can also be insulated to keep out cold draughts, and to cut down on self-watering when it rains.

Bubble wrap, which you can buy in rolls from any local DIY store, does the job really well.

As you can see from the above photos, making greenhouses from plastic bottles seems to be popular as a community effort. But I would like to build one for myself, primarily because of its cheap construction.

In Europe, building plastic bottle greenhouses has become a popular past time for many. I have been unable to locate information as to whether the plastic bottles stand up well under a hot sun, which is normal where I live (in southern Spain).

Plastic bottle houses stand up very well in sunny conditions in hot countries, but the plastic is not really exposed to a lot of sun, being filled first with sand and then covered by mortar. Filling with sand is NOT an option for a greenhouse as it then becomes a garden shed or something!

If any architect reads here, I would welcome your opinion, before I go to the effort of collecting thousands of empty plastic bottles.

        This looks like an awesome idea. I plan to start with making a wall to protect my poor plants on my roof from the wind. Also, thinking about a dog house and then a greenhouse. I live in tropical Taipei. I saw some discussion about heat melting the bottles. I would think that would be a super big problem here and that's why I'm starting small. What about painting the bottles with something to help reflect the sunlight?? Anybody try something like that?

        First and foremost thank you for the great idea. I was wondering how to contact rachel Smithh who lives in Arizona? I also live in Arizona and would like to know what she found out on the sun and these bottle greenhouses. I would also like to know since I am building a walipini, and I would only need the roof portion of this concept, if anyone has thought of cutting the bottles in half lengthwise so fewer bottles are needed? Is there a reason I guess the question I need to ask is why the bottles are always kept whole? I never really see answers to questions here is there a reason for that also lol just full of questions today sorry.

        I heard that plastic bottles labeled 1 (PET or PETE) are only safe for a single use. When exposed to oxygen or high temperatures, including sun heat, such a bottle will discharge toxic substances that get into the water will those bottles also discharge toxic substances if used for a greenhouse made from plastic bottles?

        One of the above headings says 'It saves more plastic from going into landfill sites'. I live in Great Dunmow, Essex and our plastic bottles go into our green recycling bin along with paper, cardboard, tin and glass. Does this not happen in other parts of the country? However, we have a community group who are going to build a greenhouse so at the moment ours are taken to the Library which is the collection site.

        Saying that building the frame out of wood is Green doesn't make much since IMO. Wood is by nature GREEN. It is replenish-able, certainly PVC or Metal conduit wouldn't be GREEN. Maybe bamboo would be a good alternative as it is faster growing than most construction grade woods.

        If you've got someone that's handy with a chain saw you could have them split a small log for the use of framing.. I was thinking if you cap the bottom bottle and stack them and turn the bottoms upward and catch the rain in the bottles it would create more heat when warmed by the sun.

        Wow What an idea to upcycle plastic bottles. If we made them bigger they could be shelters for the homeless. I would live in one. They would be warm. This has great easy to follow instructions. Maybe the frames could be pvc pipes. The pipes could be drilled out and the cane poles would fit right into the holes.

        well I think we are going to find out how well it will stand up to extreme sun and heat I live in buckeye Arizona we've been known to easily have 115 to 126 degree summers so after I can get one built which will take me a little while to do since it will be only me building it. i'll let u know jus how well it will stand up against our scorching summers I'm jus hoping it doesn't wilt melt or combust from built up heat trapping in bottles over time . I've seen many things out here heat pressure explode from tires on parked cars the huge glass trunk window on my parked Trans am trash cans to bottles. so this could interesting if the ends heat seal to the inner lock bottles.. guess there's only one way to find out build it way Frm house and see what happens over time. I'll keep u posted if goes well or not. if anyone else lives in harsh place like mine and worry bout that u can always drill 1 small hole in side of bottles on the inside of green house. I've seen plastic bottles out here worp & melt together so I have 50/50 it could go either way but I'm a risk taker & not gonna drill vent holes .

        I've been collecting bottles for about a year and a half, from personal consumption and a few parties. Stored some in my shed, but soon had too many. Began putting them in big garbage bags and storing them under the shed. Decided to go ahead and remove labels and bottoms of the bottles as I collected them, so I could fit a few more in each bag.

        Discovered wind can blow a bags of empty plastic bottles from under a shed, and sprinkle both bags and bottles all over a lawn. Weather weakens the bags, too.

        Decided to go ahead and string them like beads on some clothes line. It takes 10 bottles to make a column 8 feet tall. It takes 3 columns side by side to make a panel a foot wide. So to make a 4X8 panel, the size of a sheet of plywood, one bottle thick it takes 120 bottles.

        3x4=12. 12x10=120.

        Interesting in theory, but there is nothing 'less green' about using wood for a frame if it comes from a sustainable source, or reclaimed wood is used. Our kennel is built out of my fathers old garden shed, which started life 50 yrs ago as a henhouse. Not green?

        It seems like if you could arrange it so that you didn't have to cut the bottom or top off and filled it with some clear liquid that wouldn't evaporate (I'm not sure what that would be), that would add insulation. If you added water and glued the lids back on, would the water evaporate? I am not a scientist as you can tell, but surely someone could come up with something.

        Your seedlings will need light. I would honestly start them off elsewhere and put them into the greenhouse at the height of summer. I imagine the summer sun in France would be too hot for them. and a green shaded greenhouse will help keep them cool. The other thing you could do is build your greenhouse with green bottles, but make sun windows with clear plastic bottles and place your seedlings under them?

        Martine 4 years ago

        Thanks for the reply IzzyM. Another question though...would there be enough light inside the greenhouse to start seeds in spring, as the bottles are a quite dark green colour? I've read that one needs a grow light? No problem with heat I think, as it gets very hot in France.

        Guess I'm coming to this hub a bit late, but, you say in it that you would like to have a construction without a wooden frame.

        Thinking about it, I reckon you could construct a bottle greenhouse in a similar manner to a polytunnel.

        The bottles could be formed into a curved frame, replacing the 'scaffolding poles'. creating the semi-circle by utilising flexible cane similar to that used in pop-up tents - there must be a better way, though.

        This could be continued all the way down the length - this way the construction could be as long as you require. Otherwise use straight sections of bottles to join a number of curved sections together, and then cover with polythene, or bubble wrap.

        The ends could be constructed as per your instructions, or they too could be covered with plastic / bubble wrap (in two sections, so that one can gain access).

        Hope I've explained this so you can understand what I have visualised in my mind.

        If I had a garden I'd try this for myself.

        Many thanks, Kasman! Collecting bottles takes the longest time, so it might be an idea to start now, even though you are not ready to construct the greenhouse. Of course it doesn't have to be a free-standing structure. The choice is yours, it could be a lean-to, a mini-greenhouse, a covering for a raised bed garden, or many other potential designs. PET plastic is top-grade and will withstand almost anything so should last for years.

        Thanks to all the commenters for the vote up, and especially for the sharing.

        @Jim, thanks for the advice! I do tend to get carried away sometimes with my own enthusiasm, and will take time to go through the hub and correct punctuation and sentence length - you are right, I do tend to write long sentences and it's a bad habit.

        I'd drink to that! Your greenhouse project scores high on so many levels--recycling, waste stream reduction, organic gardening, community building to mention but a few. I thoroughly enjoyed reading this Hub and gladly share it with my Facebook friends.

        Now, if I may be allowed a bit of critique, the conversational style of your writing is quite engaging and enjoyable, as if you were standing next to me and telling me about this project. Your enthusiasm shines through brilliantly. I would suggest you pay closer attention to your punctuation, particularly on the use of commas, as your sentence structure tends to be rather lengthy.

        I have heard of using plastic bottles to make a greenhouse. Thanks for sharing all the steps! What a wonderful way to reduce waste in our landfills and have the benefit of a longer growing season! Pinned and voted up!

        Up, Useful, Interesting, and shared with followers and on social networking sites. One of these years if my thumbs turn green I'll participate at a community garden, and making a communal greenhouse for it together out of soda pop bottles might be a helpful and welcome idea.

        Thank you IzzyM for getting back to me and I see now and I completely agree with you, it is indeed a great project.

        The gaps make for great natural watering when it rains! If winds are the problem, the greenhouse can be insulated with bubble-wrap. Even so, if the basic structure is well anchored, the plants inside are still sitting happily at several degrees above the outside temperature. This idea will never be better than a proper greenhouse, but it's a cool project, especially for community groups.

        This is a great idea and I also love the video. I noticed that there were gaps in the green house and wonder how that affects the green house.

        Thanks very much! I've long used the tep liyer soda bottle, with the bottom removed, as a cloche to protect young plants. This goes way beyond that. I am definitely considering this as an ption for a summer project.

        This is interesting! It is amazing that plastic bottle can be useful for many things including making creation like this.

        It's such a shame to throw such a high grade of plastic away, and that is great to know they won't biodegrade in high UV areas. If they withstand the heat in Brazil, they'll be fine in southern Europe (which was what I wanted to know for certain).

        What a great idea. I have never seen anything like it.

        We use plastic bottles here in Brazil. On our tilapia farm we use them as floats in the lake. We suspend air diffusers from them. I have also seen them used here in family gardens to keep birds away.

        Our UV index is in the 'extreme' category and have had no problem with them cracking.

        Voted up and sharing.

        This is a very unique idea. I build more traditional buildings and homes for a living...always amazed at some of the non-traditional ideas people come up with. Great job
