Speaking of quick growth, check out the picture to the below left of the lettuce in our raft system. These seeds were planted just about 10 days ago - as just seeds. Yet they already recognizably look like lettuce. The same day they were planted I planted some lettuce seeds on the back patio of my house. Those plants just struggled through the surface yesterday and are just tiny little green leaves, not lettuce-like at all. The growth rate of our aquaponics system is astounding!
And, below right, you can see the fish. They're growing really quickly and are friendly and curious. They check out anything entering the water and are really enjoying their big tank. They're already more than twice the size than when they arrived.
