You can, and that is how most people populate their tanks. But corals can appear to grow from LR.
When coral grows from LR, what is actually happening is a small pollip (like a seed or egg) of coral is already there but too small to be seen. When the conditions are right the pollip will grow into a coral that you will notice. So, does coral grow from LR? Yes and no, suppose it depends on your definitions.
