Actually, shawn was by the other day and I think I can flood the lower barn (without a roof) and even pump water from the lagoon (nutrient loaded and an instant bloom). There are about 40 pens and each could be used to isolate a unique variable as well as being subject to the same environmental conditions (WQ, light...). I'm not sure why you would want to provide "supplental feed".
Let me know the next time you'll be at the lake and we can take a look at it.
