You can eat rice and potatoes if you have diabetes. However, you will need to eat smaller portions. One medium potato (3 potatoes / pound) is a serving. Find 3 potatoes at the store and put in the scale until it equals one pound. Rice can be a challenge because a little goes a long way for your carbohydrate count.
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 weâve 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.
Growth rates of duckweed colonies will be reduced by a variety of stresses: such as nutrient scarcity or imbalance; toxins; extremes of pH and temperature; crowding by overgrowth of the colony and competition from other plants for light and nutrients.uckweeds have been fed to animals and fish to complement diets, largely to provide a protein of high biological value. Fish production can be stimulated by feeding duckweed to the extent that yields can be increased from a few hundred kilograms per hectare/year to 10 tonnes/ha/year.
