Why choose the Superplant HPS Killer 660W?
Among the lighting solutions on the market, the
Superplant
HPS Killer 660W stands out as an interesting alternative in many respects. This
LED
powerful light source offers a light spectrum optimized for growth and flowering, while consuming less energy and producing less heat. Thanks to its high PPF efficiency, it guarantees ideal light output for your plants, while reducing your energy costs. Yields were therefore more than respectable in view of measured consumption.
Unless you want to manage several devices at the same time, it's best to consider first and foremost the quality of light, which is a fundamental element in ensuring vigorous growth and maximizing yields in indoor cultivation, whether hydroponic or organic. Whether you're growing vegetables, fruit or demanding tropical plants, choosing the right light spectrum is a must.
What's more, the grip was pleasant and the feeling of sturdiness was more present than on the Bright 720W, plus the warranty offers 3 years' peace of mind, i.e. one year more than on the Bright.
