build & spectrum
Our red + far red booster spectrum will help you grow the largest and most dense flowers. Super bright full spectrum 4000K diodes operate at an efficent 2.3umols/j plus 660nm red and 730nm far red diodes in a cool square within a square within a square design. This light can run full cycle from seedling to veg to flower.
Proven results with the Square 3 Far Red Spectrum
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.
