HID Grow Lights (HPS & MH)

Unlock Professional Yields with High-Intensity Discharge (HID) Lighting

High-Intensity Discharge (HID) lighting remains the most trusted technology in the hydroponics industry for producing heavy, high-quality harvests. While many modern growers explore LED options, traditional HID systems—including High-Pressure Sodium (HPS) and Metal Halide (MH)—offer an unbeatable combination of raw power and deep canopy penetration. At The Horticulture Company, we stock a comprehensive range of HID kits designed to suit every environment, from compact hobby tents to large-scale commercial rooms. Because we understand that every grow space is unique, we provide expert guidance to help you select the ideal wattage for your specific needs.

Choosing the Right Wattage for Your Grow Space

Selecting the correct wattage is essential for balancing light intensity with temperature control. If you choose a light that is too powerful for your space, you risk heat stress; however, a light that is too weak will result in airy, underdeveloped flowers. Consequently, you should match your light to your floor space using these industry-standard guidelines:

• 250W HID Lights: This compact option is perfect for small tents (approx. 0.6m x 0.6m or 0.75m x 0.75m). Because they generate less heat, they are an excellent choice for beginners or those growing in tight cupboards.

• 400W HID Lights: We recommend this mid-range power level for 1m x 1m areas. It provides a significant step up in intensity while remaining relatively easy to cool with standard ventilation.

• 600W HID Lights: Often called the “sweet spot” of indoor growing, the 600W lamp is the most efficient HID size. It produces more light per watt of electricity than any other variation and perfectly illuminates a 1.2m x 1.2m space.

• 1000W HID Lights: For professional results in 1.5m x 1.5m areas, 1000W systems provide unmatched penetration. These units are ideal for taller plants and dense canopies, although they require robust extraction systems to manage the heat.

HPS vs. MH: Managing the Spectrum for Every Stage

To achieve the best results, you must understand the difference between the two primary HID bulb types. Metal Halide (MH) lamps emit a crisp blue light that mimics spring sunshine, making them perfect for the vegetative stage. In contrast, High-Pressure Sodium (HPS) lamps provide the warm red and orange spectrum required for the flowering phase. Therefore, many of our customers choose “Dual Spectrum” bulbs or switch lamps as their plants transition, ensuring the garden receives the exact energy it needs at every moment.
