We are waiting for the coming season, the spring.
I want to grow some tomato on my balcony. So i seed many different tomato sort. All of them sprout and I have to prick them into a pot.
Because i had not enough small plant pots i made some of old newspaper.
How i did it, you can see in this instructable or in the video, where i explain it in German. https://youtu.be/ihZBykvZeqA
Step 1: Cut the Newspaper to the Right Size
The size you need depend on the size of the pot you want to make.
I just cut one page of the newspaper height-wise in half.
You want to have a sheet long enough to fit at least 5 times the diameter of the pot. The height has to be approx. twice the height of the pot.
The fastest way for me was to fold the newspaper and use a knife for cutting the paper.
Step 2: Prefold the Rim
Later we want to fold the rim inside. This is much easier when we prefold it.
Fold 1-2cm on the long side. Reopen the fold.
Step 3: Wrap the Newspaper Around a Thing
I use a jam jar to wrap the newspaper.
With the Thing you use, you decide witch diameter you pot will have.
In my case the jar has a diameter of 7cm.
Step 4: Build the Bottom of the Pot
To build the bottom i simple fold four times the shell to the middle.
It is important to have the jar still inside the paper. It helps to fold the bottom.
The folds don't have to be perfect. But if the shell is to long it is difficult to fold it. (As soon the paper is wet, the bottom will be perfect flat, even if there are some wrinkles.)
With two finger i sculp the edge of the bottom.
Step 5: Remove the Jar and Fold the Rim
Now we can pull out the jar.
When we fold the prefolded part of the shell to the inside to sculpt the rim, the pod gains stability.
Step 6: Fill the Pot With Soil
Now you can fill the pot with Soil
I used quite dry soil. So i saturate the pots some hours with water before i went to the next step.
Step 7: Prick Your Seedling Into the Pot
Finally plant you seedling into the pot.
Don't forget to water them frequently!
If you have more than one sort of plants you have to go to the next step.
Step 8: Label the Pots the The Name of the Plant
With my 3D-Printer i make a sign to label the Pots.
If you want to adjust the size you can edit the fusion 360 file http://a360.co/2nSY1Ot
