HOW MUCH LIGHT DO YOUR CANNABIS PLANTS REQUIRE?
Clones and seedlings: 5,000–7,000 lux
Vegetative growth: 15,000–50,000 lux
Flowering: 45,000–65,000 lux
Maximum recommended amount of light: 75,000 lux
What about even more light? At some point, increasing the light beyond a threshold plant can manage will actually diminish returns. Said differently, once you reach about 85,000 lux, it’s simply too much. Some strains may already show signs of light stress at only 75,000 lux, with the risk of light bleaching increasing at over 80,000 lux. To keep it safe, it is best to stay at or below 75,000 lux.
Happy growing! 👊
