The PowerGrower plants are now receiving light from a High Pressure Sodium bulb (HPS) that we swapped out with the Metal Halide bulb. Our ballasts are the electronic/digital type that can support either type of bulb.
We are using the HPS bulb now as the plants (mainly the Cherry Toms) are in the Generative stage and require more red color in their light spectrum for the best flower and fruit growth.
