hi, This is my first post to this site and hello to everyone. I live in plantation fl and started a small aquaponics system in my backyard. I am following Murray Hallams systems from australia. I want to raise blue talapia for food for personal use. Does anyone know where I can get duckweed? Here in plantation they spray the lakes and ponds to kill it so i cannot find it here. Any help greatly appreciated.


Thanks
John Mark
