Small continuity issue

In previous Tex Murphy games, domestic plants seem to be very valuable, but in Tesla effect there are quite a few and not special. You even get to grow a big plant in a few seconds! I know it was just a voice over joke, but got me thinking.
Anyway, I'm on the fourth playthough and I still discover new things, the story gets richer every time. I love it and will need more soon! :D
