  • 600W: 30 – 46 cm (12 -18 in)
  • 400W: 23 – 30 cm (9 -12 in)

Higher wattage growth lights emit more heat compared to lower wattage grow lights, therefore, it is critical to consider the distance of the hydroponic light. Generically, growing areas are shown as a function of wattage.

  • 150W: 6.5 ft2 (0.6 m2)
  • 250W: 9 ft2 (0.8 m2)
  • 400W: 11 ft2 (1 m2)
  • 600W: 13 ft2 (1.2 m2)
  • 1 000W: 16 ft2 (1.5 m2)

Temperature

Some bulbs emit much more heat than others, so it is important that you manage the temperature so as not to damage your crop.

Area of coverage

A common mistake is to grow as many plants as possible in a small area under the lamp, causing shadows, hence lack of light for some of the plants. So, make sure that the entire hydroponic system receives the appropriate light.
