Q.Chinese Cabbage
I am a student doing a scientific experiment concerning the Chinese cabbage. Specifically, concerning the Chinese cabbage, I have two questions:
1. Will Chinese cabbage survive if grown in a sponge?
2. How long will Chinese cabbage take to germinate?

Germination of chinese cabbage happens in 4-7 days. And you can start your seeds in a sponge using the instructions in the following article.
