COVERAGE
The Square 3 is designed for flowering in 3'x3' spaces at up to 1000 umols/ms. (CO2 recommended for this light level). Or grow at 800 umols/ms without CO2. It can be used for Veg when dimmed. And when fully dimmed can be used over clones and starts too.
Below are PAR readings with the lights at three different distances. At 24" expect PPFD to be above 1000 umols/ms, but not as uniform.
At 30" PAR will be above 750 umols/ms. This is an ideal light level if not using supplemental CO2. These levels are equal to a typical HPS grow space.
At 36" light levels become more uniform from corner to corner but at 680 umols are below what we'd recommend for flower.
At 48", light levels are the most uniform and are perfect for mature veg plants. Use the built in dimmer to reduce intensity for young veg plants.
