DMXGROW LP960 LED Grow Light with Higher PPFD for Cannabis growing
First, understand what color of light is best for plant growth?
Purple and blue light in the range of 400-520 nm promotes chlorophyll absorption, photosynthesis and growth. Red light in the 610-720 spectral range promotes flowering and germination.
Plant grow light should provide a suitable spectrum for photosynthesis, which is the key to plant growth. Most LED grow lights offer two colors, spectral illumination and even full spectrum.
In order to determine the optimal grow light size, it is important to consider the optimal PPFD (optical density) for growing marijuana and how to convert the optimal PPFD to the optimal PPF (light quantity).
Best PPFD for marijuana:
The data of Chandra et al. Confirmed that the optimal photon density of cannabis photosynthesis peak is between 500 and 700 µ mol / m2 (PPFD), of course, this refers to the average value. It also shows that we should avoid exceeding 1000 µ mol / m2 (PPFD), which may cause damage. With artificial lighting, the distribution of light will never be perfect. Therefore, we want to ensure that all areas of the canopy reach at least 500 µ mol / m2 (PPFD), and no point has an absorption of more than 1000 µ mol / m2 (PPFD). We recommend an average of 700 µ mol / m2 (PPFD). For most growing lights, an average of 700 lights will ensure that you are within the optimal peak range of photosynthesis in all areas of the canopy.
Best PPF for marijuana:
PPFD is a density measurement expressed in micromolars per square meter. To convert PPFD to quantity measurement, we multiply it by the area in square meters. Since the optimal average photon density is 700 µ mol / m2 (PPFD), the optimal number of photons is 700 µ mol available PPF per square meter. This translates to 65 µ mol of available PPF per square foot. To calculate the total amount of light required to grow space in the available PPF, simply multiply the area by 65 square feet × 65 = µ mol available PPF).
