MH & HPS bulbs are essential elements of indoor grow light systems, providing specific light spectrums suitable for different stages of plant growth. Metal Halide (MH) bulbs emit a bluish-white light ideal for vegetative growth, while High-Pressure Sodium (HPS) bulbs emit a reddish-orange light beneficial for flowering and fruiting stages. These bulbs are essential for indoor gardening, offering growers versatile options to meet their plants' needs throughout their growth cycle.
