Oh My!!! Now, if only I could control the Sun with my phone APP, but now I can...INSIDE

Reviewed in the United States on May 25, 2022

This is a game changer for my plants. From my phone, I now control the temperature by increasing or decreasing the light intensity. I also control the time for sunrise and evening for my plants. And, even though I'm not found of clouds the variations of light actually helps to stimulate plant life.

In short, this light is so easy to use and so beneficial for my indoor plants. It is actually easier than turning on and off a light switch. Everything is now controlled by my phone APP. Perfect!!!

Our new Square 3 V2 is the most advanced mid-wattage LED on the market today and the best light to buy for a 3'x3' flowering space.

Meet Your Next LED Grow Light

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.

Included WiFi and Push Button Dimming Controller

• Lightweight - just 13 lbs

• Slim - 3" deep

• Cool - won't add too much heat

It also has 4 push button dimming settings so you can pause to work with your plants under less or no lighting without interrupting the schedule.

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.
