Siting A Hydroponics Operation
Farmer's Weekly
|March 1, 2019
Before buying a property on which to build a hydroponics operation, it is crucial to do some research about the site. This includes reviewing climatic data, making enquiries at the municipal or district council, and having the water tested. Research will save you effort and money in the long run.
-
The following factors require special consideration:
Water
What is the main source of the water? Is it a river or stream, a borehole or well, the local municipality, or collected rainwater? What is the quality and quantity of this water, and by how much do these vary? How reliable is the source during drought?
The amount of water needed is determined by the type of crop, the type of hydroponic system, and the climate. More water is required in a hot climate, as the rates of transpiration and evaporation are relatively high. Large plants such as tomatoes and cucumbers use more water than small plants such as lettuce.
The location you choose for your hydroponics production unit can make the difference between success and failure. Here’s what to look out for. Remember that water is also needed for washing produce, drinking, and sanitation.
Topography
If an open system is planned, the site should be as level as possible. A closed gravel system requires a slight slope.
