Once the moss is ready, you can start planting it.

Planting the Java Moss

You can use artificial lighting or natural lighting, both will work well.

Feeding the Java Moss

In addition to providing the Java Moss with adequate light and humidity, you will need to feed it. You can use liquid fertilizers or you can add small amounts of fish waste to the water.
