It would be nice to add to the greenhouse configuration, the ability to change the layer of the dirt, or to be able to use any dirt, this will add compatibility with TFС

Preferably, you would add a recipe in your modpack that turns TFC dirt into normal dirt for now. I will see how doable this is in the future though.

Do you need specific states of a block to get things properly working with TFC?

yes, it is desirable to add this, it will give free rein to the configuration
