The FGI Square 3 is our new favorite compact flowering LED.  Super bright full spectrum plus red and infrared diodes in a cool square within a square within a square design. This light can run full cycle from seedling to veg to flower.  

PAR levels at 15" are equal to a 1000W HPS. At 12" PAR levels exceed 1000W HPS. Cover a 3'x 3' area at 700 umols/ms uniformly, veg up to a 4' x 4' at 400 umols/ms uniformly. (The Square uses Far Red diodes which increase photosynthetic light levels and are outside of PAR measurements). 

Measuring PAR under the Square 3

What makes the Square different? We add both 720NM (far red) diodes as well as 660nm (red) diodes along with 4000K CCT full spectrum.

Top bin Shenzhen Ledida diodes. Including 6% 720nm infrared plus + 27% 660nm red which growers have found is the key to potent flowers.
