HID lamps

H.I.D Lamps have been a cornerstone of indoor growing for decades, delivering powerful light output that plants can use throughout their life cycle. Known for their balance of strength and value, they remain a reliable option for growers who want proven performance at an affordable cost, even as newer technologies like LEDs continue to grow in popularity.

Popular options include Metal Halide (MH) lamps, which provide a blue-white spectrum ideal for vegetative growth, and High-Pressure Sodium (HPS) lamps, which deliver the red-orange light needed to drive heavy flowering and fruiting. Many growers switch between the two to give plants the best spectrum at every stage, while dual-spectrum lamps combine both benefits in a single bulb.

For growers who want tried-and-tested lighting solutions, we recommend H.I.D Lamps from Greens Horticulture — delivering strong performance, excellent value, and fast UK delivery.
