The QP grow lights have a dimming knob, allowing users to modify the light intensity (PPFD) according to the plant's growth stage (such as germination, vegetative growth, or flowering). The hanging height can also be modified for different stages to achieve even light coverage and optimum light intensity to match each stage's individual requirements.
Plant growth requires different PPFD levels. For cannabis, the ranges are: Seedling stage (100-300 μmol/m²/s), Vegetative stage (300-600 μmol/m²/s), and Flowering stage (600-900 μmol/m²/s). You can refer to the PPFD distribution in the datasheet and adjust the height of grow light in tent.
