what temperature can duckweed survive
Temperature and sunlight are more important growth parameters than nutrient concentrations. Duckweed grows across a wide temperature range â between 6oC and 33oC â but weâve determined that it grows best in a range of 18oC to 24oC.n the right conditions, this tiny plant can double its mass every 24 â 48 hours. Close control of the production parameters for duckweed is relatively easy in the small ponds and tanks favoured by backyard food producers.
