Hi, Ive seen Duckweed before and would like to know what your asking for enough to cover a 55G long tank. Ive never seen Giant Duckweed? Please send pics and price ; )

Melissa, is duckweed completely killed in the cold winter waters of Massachussetts? I wonder how far north it wil survive? Here it clogs slow moving rivers and can cause fish kills when it "blooms" and depletes oxygen in the summer waters.
