Answer2:I understand your concern about not having a harvest since 20h ago. It is possible that the well pool is not producing the desired yield due to a variety of factors, such as the water level, the quality of the water, or the amount of sediment in the water. It could also be due to a lack of nutrients or other environmental factors. If the well pool is not producing a sufficient yield, it may be necessary to investigate further to identify the underlying cause and find a solution.
