Several factors should be considered before buying the site for your hydroponics production unit. Some information is not always immediately evident, and you’ll need to do some research. This includes a study of climatic data, enquiries at the municipal or district councils, water tests and so forth. Research is always worth it as it might save you money in the long run.
The following need special consideration, says JG Niederwieser, editor of Guide to Hydroponic Vegetable Production.
WATER
What is the main source of water? Is it a river, borehole, well or is it provided by the municipality? What is the quality and quantity of the water available during a normal year? How reliable is the water source during periods of droughts?
The amount of water needed depends to an extent on the type of crop, the type of hydroponic system to be used and the climate.
More water is needed in a hot climate as the rate of transpiration and evaporation is relatively high. The large plants such as tomatoes and cucumbers use more water than small plants such as lettuce.
