I dose first thing in the morning right after the tank lights come on. The plants take in the light to stimulate growth and nutrients in the water to provide nourishment to sustain the growth.
I like to dilute both macro and micro nutrients in the treated water I use to top off my tanks. All my tanks are open, so I top them off 2 to 3 times per week. The land and aquatic plants seem to like the feeding routine. The Pennywort grows outside the tank. See attached pics.
Nice setup, my buddy is all about the aquaponics scene and im all about the aquatic scene. We're always trading wet and dry plants. But neither are using dry ferts or much wet ferts at that. Those top plants are thriving. Ill show him a pic of them aand hopefully get him on some fert dosing.
