The FGI Square 3 is our original 320W full spectrum + red + far red LED flowering light. This light can run full cycle from seedling to veg to flower. Our innovative square within a square within a square is designed for maximum light coverage and intensity.

Meet the Square 3

Maximum yield and potency is always our goal. The Square 3 lives up to it's reputation as our top 3x3 LED grow light. Grow with precision and control using the built in variable dimming. 

Cover a 3'x 3' area at 800 umols/ms uniformly, veg up to a 4' x 4' at 400 umols/ms uniformly. 

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

The Square 3 produces uniform PAR over a 3'x3' space due to it's unique design. Ideal hanging heights depends on your grow environment. For a 3'x3' tent for example, the ideal height above finishing flowers will be 30". PAR levels will be about 650 umols on average.

For growers who supplement with CO2 the hanging heights can be reduced to 24" which will improve light intensity.

Top quality construction including a clear lens to protect the diodes from overspray. A full 5 year warranty provides peace of mind. And a 60 day no-hassle return policy means no regrets.

We've built everything we know about growing in to this compact 22" x 22" unit and its lightweight too at just 18 lbs. It's easy to handle and hang in any grow space.

The FGI Square 3. Give your plants the gifts that Mother Nature provides in the wild.
