Your mini-ecosystem needs light to thrive, but too much can overheat it. You might also notice some changes in your jar over time – this is normal! As your plants grow, they'll release oxygen, which your snails (if you included them) will breathe. The snails will also help keep the water clean by consuming algae.

Don't be alarmed if you see some condensation on the inside of your jar. This is actually a good sign. It means that the air inside is moist, which your plants need to survive. However, if the condensation is excessive, it could mean the jar is too humid. Simply open the jar for a few minutes to allow some air to circulate. You can also gently wipe the inside of the jar with a dry cloth. If any of your plants start to look wilted, simply add a small amount of water to the soil. But remember, less is more! Too much water can drown your plants.

As you watch your ecosystem thrive, you'll gain a deeper understanding of the interconnectedness of all living things.
