FGI Square 3 WiFi LED Grow Light, Extended PAR 400-760NM with WeatherEFX

The FGI Square 3 WiFi LED Grow Light is our most advanced mid-wattage LED on the market. It is the best light to buy for a 3'x3' flowering space. With Cloud Intelligence, you can control on/off schedules, build sunrise/sunset scenarios, and check in on your lights from anywhere. Take your garden to the next level with more natural lighting using FGI's weatherEFX. These are 1 minute dimming scenarios between 100% light output and 20%.

SCIENCE

Botanists studied the effect of leaf shading and competitive growth responses here: Importance of Intermittent Shade to the Ecophysiology of Subalpine Herbs, A. K. Knapp, W. K. Smith and D. R. Young from the Journal: Functional Ecology.

"A reduction in sunlight caused by clouds, appears to result in substantial increases to water status, and thus CO2 uptake throughout the day. Plants benefit in periodic reduction of evaporative demand that result from natural periods of intermittent shade."

DESCRIPTION

Yield and potency. Always trying to improve. If you are a serious grower you need lights that are optimized in both spectrum and light intensity. There are very few lights built like the Square 3 V2 and no better company to do business with than Forever Green Indoors.

The new Square 3 will put you in complete control of your grow lighting from anywhere on the planet. The included Wifi mesh controller connects seamlessly to the cloud. Just open the App and check your lighting levels and room temperature. The "set it and forget it" programming lives in the controller and not on the cloud so even if your wifi goes down your lights continue to follow the program.

FEATURES

• Lightweight - just 13 lbs
• Slim - 3" deep
• Cool - won't add too much heat
• 4 push button dimming settings

BUILD

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.

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.
