1
the mineral nutrients plants need in the greatest quantities: Nitrogen (N), Phosphorus (P), and Potassium (K)
2
evaporation or loss of water through plant surfaces
3
the process by which the plant sugars produced in photosynthesis are used up (or burned) to produce energy for the plant’s life processes
4
the art and science of crop production in liquid media
5

6
refers to any system that combines conventional aquaculture (raising aquatic animals such as snails, fish, crayfish or panfish) with hydroponics in a symbiotic environment
