Hydroponics, while somewhat similar, is actually much different than aquaponics. The biggest difference, of which I’m sure you’re aware, is that there are no fish. In aquaponics, fish provide many necessary plant resources by pooping and participate in numerous biological processes including nitrification. Largely, the only grower input is fish feed and nutrient supplements.
In a hydroponic system, the grower is responsible for providing all of the nutrients as a mixture in addition to supplementing. Therefore, you will need to understand the necessary inputs, what to monitor, and what not to do.
The following is a list of guidelines rather than strict rules—every system is different based on type, grower, inputs, and crops. Keep that in mind as you use this handy dandy hydroponic reference guide!
