Lemna (Lemnace), commonly known as duckweed, is a fast growing, tiny flowering aquatic plant that floats on surface of fresh or brackish water. It doubles its growth in 24-hours and can yield 30+ dry tons of biomass per year/acre. With the additional of optimal nutrients and temperatures up to 75 ton/ac are possible. Duckweed grows from tundra to the tropics. It is often used in wastewater treatment because of its ability to uptake nutrients and can grow in brackish salt water. Five main families and 47 species of duckweed have been identified and analyzed for different climate zones and environments.
Lemna Duckweed and Spriulina Algae are two of the fastest growing vegetable crops with highest yield and most nutrient dense. Crops may be eaten dried or fresh as a whole food. Or they can be mixed as an ingredient in animal or fish feed or in human foods such as baking goods or sports drinks.
