The Grower's Choice 4K bulb is a slightly warmer metal halide, making it suitable for both flowering and vegetative growth. Growers get the most use out of this style of bulb towards the end of the vegetative stage.

4K DE : Full Phase

• Grower’s Choice 4k DE lamp is a versatile lamp with the ability to carry your garden from veg to bloom if you are looking for a general-purpose lamp. The GC 4K DE lamp performs best as a vegetative lamp and supplemental lighting with HPS lamps to enrich the par spectrum for larger and higher quality yields.
