Summary

With this model, you can upcycle the glass jars commonly found in Europe into mini greenhouses for your plants. It has a water reservoir and a lip to collect condensation water and re-inject it in the reservoir (See cross-section image for detail). With the hexagonal design, you can pack them in a honeycomb pattern or mix sizes easily.

I have created 4 models matching 4 different sizes but you can easily design new sizes for your jar.

To find your size, measure the outer diameter of the opening of the jar.

The 72mm is also available with larger sides because my apple purée jars have narrow opening but are quite wide, this is to allow to pack them together without the glass touching.

Watering tips:
If you keep the glass jar on it, don't use the reservoir or keep the water level in it very low (0,5 cm), because the greenhouse will be closed, the water that you put will not evaporate and the soil will be too wet. Use the reservoir only when not using the glass.

Happy Farming!

Print Settings

Printer Brand:

Prusa

Printer:

Prusa Mk2

Rafts:

No

Supports:

No

Resolution:

0.2


Notes:

As the design is quite simple, you should be able to print at fast speed. Printing at 60 or 80mm/s should not be a problem on a Prusa i3 MK2.

If your printer allows it and to add some color, I suggest that you do a color change at layer 251 (Z 50.2mm).

If you are using Simplify 3D, you can rotate your model on the z-axis by 45° to align top solid infill with the side for a nicer look.

Wall thickness is designed to print 2 perimeters at 0.45 mm layer width.

How I Designed This

Edit it to fit your jar!

I designed this in Fusion 360 and it can be easily modified to fit more glass jars.
You can download my designs from Autodesks' A360.

I thought that PLA degrades when in contact with water? Is that a misconception?

52.5mm design fits Australian Masterfoods Ginger jar. Most standard jars in Australia are ~58mm looking to see what % scale i need to change the print to get it to fit.

I scaled the 62cmm one by 96% to fits the 58 cm and it works well

you got a nice thing going on here :) I Like it!

non 3d print related noob question... this will protect the plant from frost right?

Nice idea. The design is a bit flimsy though, easy to damage or break. I think if the walls were a bit more thick it would be a lot more durable.

Hello,

Thank you for your comment! Yes you are right, the initial idea for having thin wall was to be able to see the level of water through the wall and also to use as little material as possible but I agree I could make the wall 3 or 4 perimeters instead of 2 because if the jar is a bit stuck while trying to unscrew, you can break the thing.

So...Where the plants get Carbon dioxide and oxygen?

what kind of threading did you use? i want to remix this

Hello,

I copied the threading used on the lid of european glass containers. Basically it is just 4 or 6 little tabs depending on the lid size. Mason Jars are using one continuous thread so it is not the same.

can you possibly post a link for a version w/ mason jars, or find out if the right type of jars is available on amazon? if so, please post link

I can try, I don't have a Mason jar and I don't know if they are all the same size but I can take a thread from another thing on Thingiverse

Will this work with mason jars

Hi SMuly,

I don't have access to Mason jars in Europe, but I believe they have a continuous screw thread whereas jars here are 4 or 6 partial threads so it will most likely not work but there are other people who created the same kind of thing for Mason jars before me.

Doesn't plants need C02 to do their photosyntesis? I believe covering plants like this is mostly done for seedlings to keep mositure inside but will not work well in the long run for larger plants.

Most green houses got some way to get air into them, a lot of plants that are grown inside also got their own C02 generators when there's enough of them. If moisture content is too high as well, it will promote plant disease.

Also second problem, if the roots reach the bottom they will end up rotting, but it's not a big problem if the plants aren't large.

Looks nice though!

Plant cells do two things, fermentation and respiration, the fermentation produces C02 and so does respiration which the plant can use

Hi MrGemeco,

This is mostly for seedlings so CO2 is not really an issue, I doubt it will consume all of what is inside. Also, online I have seen plants in enclosed jars last for decades so I don't know of this is exactly working, not that I recommend that you don't open the jar for years. I'm conducting tests right now to see how it is going but so far my seedlings seems to like it, and when they will be big enough I will move them in the garden.

If too much moisture is an issue, the water reservoir can be used once the plant is big enough only and that you don't need the glass anymore.

I'll try to improve my design if I see problems and thank you for the comments, I don't have much experience with plants so I appreciate inputs.

basicly the plant also burns energy and thus creates its own co2. covering it won't cause the plants to die but it will limit their maximum size.

just a suggestion: It would be cool to make this as an array that has 1 common reservoir so it can be used for hydroponics

May 16, 2017 - Modified May 16, 2017

Nice idea - but i see a minor problem ... more a missing piece.
If the plant has grown a proper root ball, it can not be removed from your pot without damaging or destroying the pot or the root ball.
In order to be able to easily repot the plant, a insert is needed.
http://pichoster.adbt2.ath.cx/viewpic/planter-upgradejpgDa8VIDk.jpg
The green line represents the insert. As with hydroculture, the water is supplied to the plant with some sort of thick yarn, represented by the blue line.

My solution to this is to use Peat Pots
they are made for transplanting seed germinations. Once transplanted, the peat pot becomes part of the earth and the roots can grow past the peat pot.

Hi Balmung83, I see what you mean. While this was designed initially as a nursery for small plants before moving them to another place when bigger, it can be an issue if you keep them in this for a long period. I will work on another model or an insert to offer a solution for people who want to keep the plants in the planter.
