I posted about them here in mid august. So now's a little update.
The plants in perlite:
They are grown under florescent lights. I've taken a root cutting of about 4 inches long from the larger plant. It has a baby plant growing from another root.
A close-up of its meal.
Two plants in perlite/LFS mix:
One is almost dead but this is the other one that is taking well to the media. It is shaded by the N.emmarene during the brighter hours. It is greener than the ones under FL and I intend to give it more light later on.
