The Metrics of Full spectrum led greenhouse grow light indoor plant light
For cultivators evaluating the performance standards of today’s most prominent LED grow lights, you need to consider two important factors:
• The amount of PAR produced by the light, measured in Photosynthetic Photon Flux (PPF). • The amount of PAR that actually reaches the plants, measured in Photosynthetic Photon Flux Density (PPFD).
PPF measures and quantifies the amount of PAR emitted by the fixture. This is calculated in micromoles per second (μmol/s) and should be publicly available from the manufacturer. This is an important metric to check when evaluating the value of a given LED grow light because PAR is only a slice of the total light produced by a lighting fixture. When your focus is stimulating photosynthesis, PPF is a good indicator of how well a given light will nourish a crop’s growth cycle. High levels of PPF mean the fixture is tuned to produce plenty of PAR and support healthy growth, which is a good sign of return on investment.
PPFD takes this a step further. It’s all well and good to produce a large swath of plant-nourishing PAR, but if the beam spread of the light is a wide scatter-shot approach, only a fraction of that PAR will actually arrive at the plant’s foliage. The rest will spill into the aisles and onto the walls, which is essentially wasted energy. PPFD measures the density of the PAR actually arriving at the plant canopy.
In addition to high PPFD numbers, it’s important that the spread of light across your crop be evenly distributed. Hot spots or dark spots will over-expose or under-expose plants to available PAR and can negatively impact the quality of the overall harvest. This uniformity is a challenge for some LED grow lights, but a few have some interesting innovation in this area.
