Good job and well done!
You have already learned all about the construction and placement of your BioIntervention! Last but not least, let's get to know about sustaining it :)
Just like in our houses, the BioInterventions need some renovation or retouch every now and then. However, it is important to do so in a good time of a year, so that their inhabitants are not bothered too much.
Let's get to work and learn all about it!

Create the bottle ecosystem!
By completing this little exercise, you will easily gain an understanding of what an ecosystem is, how it works and how it changes over time. Observe carefully the life in your bottle based ecosystem and note how the synergies between each element are being constructed!
To construct the bottle ecosystem, you first need to find a 2L bottle. Clean it properly inside as well as removing any labels from the outside. Cut the bottle at around 3/4 of its height, around 10cm from the bottle neck. To ensure your cut is straight you can use tape as a level marker. Place rocks or pebbles in the bottom of the bigger part of the bottle and top it with potting soil until it is about 1/4 full. Once the soil is set, create holes for seeds in it. Follow the instructions on the package of the seed you want to use, based on that different height of seed holes will be needed. Good plants to start with are beans, mint or basil. Cover the seeds with the soil. If you wish, you can add grass seeds on top, no holes are required for that, simply sprinkle them on the top. Then water the soil with seeds in it quite generously, until it is damp. Next, close the construction by attaching, upside down, the remaining part of the bottle, the part with the neck, and tape it. Last but not least, place your ecosystem in a sunny spot but not in the direct sun and observe how it changes over time! Remember to turn it every now and then to grant equal sun access for all the plants.
