Most grow lamps have PPFD measurements lower than 900 μmol/m²/s. PPFD. The PPFD of sunlight is between 900 and 1500 μmol/m²/s. These are typically lower cost and even be connected to smartphones and used in the field. The units for PPFD are micromoles per meter squared per second (written as μmol m-2 s-1). Every 30 minutes the meter will average the sixty 30 second measurements and record the averaged value to memory. Sun System PAR Meter w/ Remote Sensor. A Lux meter (which measure lumens) is cheap and can be used in place of a PPFD meter when measuring the output of full spectrum LED boards. The PPFD of sunlight is between 900 and 1500 μmol/m²/s. CORRECTION: The conversion factor is off by 1 decimal point e.g. The meter will even turn itself on/off during this time to conserve battery. The meter can store up to 99 averages. But PAR (Photosynthetically Active Radiation) reads the Photosynthetic Photon Flux Density (PPFD). Since PPFD is a measure of how much light falls on a surface, even a small, handheld light meter or spectrometer can measure the amount of PAR that falls on a surface. For that reason, high-light plants need at maximum 8 hours of sunlight, but they need at least 12 hours of light from a grow lamp. Reactions: Tguy.
