'For best growth'

Emitting a lot of blue light, the PowerPlant Metal Halide 400w Lamp promotes healthy, green growth and gives your plants every chance during propagation.

• The blue light is essential for improving the results from your plants' vegetative cycle, promoting lush, green growth.
• These lamps are also ideal for keeping your mother plants healthy.

In addition, the PowerPlant Metal Halide 400w is incredibly efficient, producing more power per watt than most other lamps.

Tip - For the best results whilst your plants are flowering, combine one Metal Halide Bulb with three High Pressure Sodium Bulbs. During growth, use one Metal Halide Bulb and one High Pressure Sodium Bulb. Always replace your grow lamps at least every 12 months.

Other specifications of the PowerPlant Metal Halide Lamp are also available. Please see the variation tab.
