You can see that 2 of the 3 open dams at PF2 are covered now. The smaller buildings to the west and north are the hatcheries. They need a lot of sunlight for the algae to grow.
It's also a bit strange that Dan mentioned $225M to $250M NTA for Triway. The MegaFarm alone should be $180M+. So if you look at all these buildings, it's probably closer to the $293M mentioned in the 10-Q.
