You can split your plants.
I would keep the small plant and pot the larger one .
The Hydroponic thread might help as well as youtube threads.
These plants are easy to grow......you have to manage the size to about a 1/3rd of the parent size....but that is subjective to a growers preference.
Mine were in hydro for 3 years.
Awesome project to observe.
