Growers Choice ROI-E720 & AC Infinity 8" Fan Kit: The Go-To Gear for Epic Cannabis Grows

Yo, what’s good? This is your GrowApp - Cannabis Guide, and for the past five years, I’ve been dialing in my grows with the setup that’s never let me down: the Growers Choice ROI-E720 LED and AC Infinity 8-inch inline fan kit. I’ve been growing dank buds way longer, but back in the day, I was sweating yields with cheap lights and a basic fan. These bad boys? They turned my tent into a frosty bud factory, and they’re still crushing it. Whether you’re popping your first seeds or leveling up, I’m here to break down why this gear is the real deal—and why I’m sticking with it for years to come.

Why the ROI-E720 Is a Game-Changer

The ROI-E720 isn’t just a grow light—it’s a beast. With a 720W power draw and up to 2080 µmol/s (that’s light intensity plants crave) in boost mode, it rivals a 1000W HPS while using 40% less power. Its 2.6 µmol/J efficacy means every watt pumps out serious light, perfect for a 4x4 flowering or 5x5 veg setup. [1] [2]

Full-spectrum GC-3K diodes and Osram 660nm reds mimic sunlight, driving photosynthesis from seed to harvest. Expect 20-30% higher yields than HPS, with denser buds and stickier trichomes. New growers, don’t stress—I learned the hard way not to blast seedlings with full power. The onboard dimmer (100% to 25%) lets you start low and crank it for flower. Pros, the optional Master Controller adds sunrise/sunset and temp protection. [3] [4]

Why the AC Infinity Kit Rules Ventilation

Ventilation is the unsung hero of a dank grow, and the AC Infinity 8-inch inline fan kit (Cloudline T8 or S8) delivers. With 807 CFM (cubic feet per minute of airflow), it’s perfect for 5x5 tents, keeping temps at 75-85°F and humidity dialed in. The carbon filter scrubs odors—my nosy neighbor never smelled a thing! [6]

The T8’s smart controller lets you set temp and humidity triggers—like kicking on at 85°F and off at 75°F. New growers love the quiet 32 dBA hum and 10-speed settings for easy tweaks. Upgraders, the PWM motor and mixed-flow design cut power use by 30% vs. basic fans. Five years in, mine’s still running like a champ. [6]

Why This Gear’s Worth Every Penny

The ROI-E720 (~$949) and AC Infinity kit (~$150-$200) aren’t cheap, but they’re worth it. The ROI-E720’s DLC-listed rebates (25-60% back in some areas) and 54,000-hour lifespan save you big long-term. [2] [5]

I’ve had zero mold issues, and my plants’ strong stems thank the consistent airflow. Newbies, the plug-and-play design is a breeze; pros, the UV-R bar option on the ROI-E720 boosts potency. [3]

Newbie Tips from My Five Years with This Gear

Starting with the ROI-E720 and AC Infinity kit? Here’s what I wish I knew as a rookie:

  • Start dim, go slow: Set the ROI-E720 to 25% for seedlings to avoid light burn. I fried my first batch—don’t be me! [3]
  • Ventilation is king: Run the AC Infinity fan at speed 4-6 for a 5x5 tent to keep temps at 75-85°F. [6]
  • Check rebates: The ROI-E720’s DLC listing saved me 30% upfront—search your area for deals. [5]
