Baloo and I just did this on our last trip! I have lots of pictures and videos but never got them posted here on MB.
We both really enjoyed the tour. They take you into a few areas that you can't see from the ride, and then you enter the greenhouse and walk around in front of the boats. We got to taste their hydroponically-grown cucumbers and feed the tilapia.
I'd be happy to share pictures or videos if you want to see them.
