Plant rooting Ball

I am not sure if this counts as a remix of another model. I downloaded and tried to print the model linked below. It would not sit flat and I could only get the 1st few layers to print before it lifted. So I made my own, the idea comes from that model but as I had no size reference or anything I'm calling it my own model. That being said I don't know if it will work as I don't know much about this so it will take a few mounts to see if it does. It seems like it will work.

I can see that if it works I will make a few edits to make it easier to add water and to thin out the part that breaks off to adjust for branch size. But lets see if it works 1st.

The model I originally tried is.
