Tip: With a little plasticine you can fix the shish kebab in the egg wrapper. This way, the skewers are stabilized and protected from slipping out.
step 3
Now put the lifted flap on top of the skewers. The cardboard serves as a "Dachfürst" and thus marks the highest point of your indoor greenhouse. With a small ball modeling clay underneath the cardboard (around the skewer) you can protect the upper part from slipping.
Step 4
Wrap the cling film, starting at the bottom, once around the egg package - high above the prince - back down to the other side.

CD cases

From old transparent CD cases can be tinker easily and quickly and quite stable mini-greenhouses. For our instructions, we use "normal" CD cases, no Slim Case or 2-fold CD cases.
option A
For the simplest version you only need 2 CD covers and some tape.
Step 1
Carefully remove the (mostly black) CD mount from Wednesday.
step 2
Place the two covers (opened at a 90 degree angle) in a square shape. The corners can be fixed either with adhesive tape or with hot glue or superglue.
step 3
As a roof, you can either use another transparent CD cover half - this would then have to be fixed with a "tape hinge" as in the greenhouse from a food package. Or you just use some cling film with a few air holes as a roof, for your little DIY greenhouse.
Variant B

Mini greenhouse from CD case - DIY

A bit more elaborate, but a lot more stable and, above all, infinitely extendable, this variant of a CD greenhouse. Due to its stable construction, this mini greenhouse is also good for the balcony.
At least 4 CD cases are required for this.
Step 1
Carefully (!) Disassemble the CD case into its three components. Take care not to break any parts and work as little pressure and force as necessary.
step 2
Set the middle section with the CD holder aside and use the two outer parts of the CD packaging.
The front flap is simply rotated 180 degrees and put back on top of it. This is done a bit offset. The flap should snap into place or not move much.
If the two clips survive on one side, the shell sits in the right place.
step 3
If you have rebuilt all (at least) 4 cases, you can now click the many components in each other. Make sure that the resulting openings point inwards.
This creates a stable square that is similar to double glazing. As a result, this greenhouse is very stable and has better heat storage.
Tip: You can also make longer or wider greenhouses with these building blocks. If you build several modules, these can also be stacked with some glue on top of each other. Thus, you can grow the mini greenhouse with the plants.
Step 4
As a roof, you can use cling film or tinker with a little more hassle even a hinged roof of CD cases.
