Abstract
There is an increasing need to recirculate and reuse nutrient solutions in order to reduce environmental and economic costs.
However, one of the weakest points in hydroponics is the lack of information on managing the nutrient solution.
Many growers and research scientists dump out nutrient solutions and refill at weekly intervals.
Other authors have recommended measuring the concentrations of individual nutrients in solution as a key to nutrient control and maintenance.
Dumping and replacing solution is unnecessary.
Monitoring ions in solution is not always necessary; in fact the rapid depletion of some nutrients often causes people to add toxic amounts of nutrients to the solution.
Monitoring ions in solution is interesting, but it is not the key to effective maintenance.
