Why Buy From Grow Tents Depot
  • The Active Grow LoPro Max Series Luminaires are lightweight and ultra-thin LED fixtures designed to replace HPS lights in vertical racking or sea of green applications. The LoPro Max features Philips chipsets for maximum light output and proprietary optics that create uniform light coverage and deep canopy penetration for high DLI requirement plants. Each fixture comes standard with Active Grow’s proprietary Entourage Spectrum which incorporates 730 nm wavelengths to increase photosynthesis rates via the Emerson Effect. These additional Far-Red wavelengths boost healthy growth during vegetative and flowering cycles. The natural high CRI 94 light also makes plants look more vivid, helping growers spot pests and fungus like powdery mildew easier. The integrated rotary dimmer provides smooth dimming down to 10%. Growers can also dim multiple fixtures via the daisy chain power and dimming ports using a smart controller. The luminaires are DLC listed, IP65 rated for tough CEA applications and deliver a long lifetime of outstanding and consistent performance.

    Best LED Grow Light Ever. I have the 320W, first try getting 350g harvest; more than a gram a watt on first try! Makes very dense nugs all the way down the plant. smaller popcorn nugs don't exist with this light, I only get dense nugs.


    Orchids are lov'n it.


    Great Light, I have it in a 5x3 tent. It runs nice and cool. I have never had a problem with it.

    Great light, great price, great yields at only only 320watts! Put this 320w lo pro max in my 2x4 gorilla grow tent! Perfect size light that distributes an abundant even light through out the canopy. With this full spectrum led you can get as close as you want to the canopy as you want without burning. Light adjustability with just a turn from a knob from 10-100% is great feature for this light. Great for all stages of a plants life. Seedling anywhere from 10-25%, vegetive cycles from 25-50 or even 75. And flowering crank it all the way up to 100%. Depending on your environment and air flow my light was running at about 94-96 degrees F at max %. With the open design of the light bars it allows for great cooling without causing heat build up over your canopy. And only at 320watts definitely a great bang for you buck. You can expect great quality yields with this led light compared to a 400watt hps. Sometimes less is better and this light definitely holds its ground compared to a lot of other lights on the market!


    This light is really fantastic. It grows greens indoors exceptionally well at only half power. I have already harvested green leaf lettuce, romaine, kale, radish, and beets. Next will be peppers, carrots, and plant starts for the spring garden. I look forward to expanding my setup soon.
