Which product was “Gear of the Year” in High Times Magazine? The G8LED 900-watt grow light. This professional-grade light covers more than 24 square feet with a penetration depth of 60 inches below the plant canopy. You’ll have the same growing power of a 1400W HPS setup for half the cost of electricity.
Besides the power savings, LED light bulbs outlast HPS lights by more than double their maximum life expectancy. While an HPS lamp may work for up to 20,000 hours, an LED bulb will last 50,000 hours. That’s 15 years of growing!
Overview of the G8-900 LED grow light
This grow light will help you graduate from a closet setup to a production line. The money you invest will come back to you through reduced power costs and the fact that you’ll get years of use without needing to replace a bulb.
G8LED uses only 3-watt LEDs because that size is more effective at penetrating down to the lower parts of the plants. The G8-900 is made for inducing the best growth during the vegetative and flowering stages.
There is no veg/flower switch to turn on more power or other colors of light. This light uses 8 bands, not full spectrum, so every part of the light works for the vegetative and flowering stages. No light is wasted; no optical lenses reduce the power of the LED output. This makes it possible for the G8-900 to cover a large area.
Everything to make your weed grow fast and healthy
G8LED uses LEDs from reputable manufacturers like BridgeLux, Epistar, and Optotech. Along with the red and blue lights you can see, there are infrared (IR) and ultraviolet LEDs making up the 8-color spectrum emitted by the G8-900.
Everything about the light is made to last. The panel has zener diodes to protect from surges and failure from burnouts. There’s no problem running the light for 18 hours a day while your plants are vegetating. The fans mounted on the top side of the panel expel hot air but the LEDs still run a lot cooler than traditional lights. They won’t burn the plants or you.
Best way to hang the G8-900
Putting this powerful light panel too close to the plants won’t burn them or dry them out, but they will discolor and their growth will be stunted.
G8LED recommends hanging the panel 26 to 42 inches from the top, or canopy, of your plants. If you want taller plants, stick to 42 inches so they will stretch. For shorter, bushier cannabis, lower the light to 26 inches above their tops.
Size, weight, and power needs
This 23-pound light measures 20.5 by 14 by 3 inches. It comes with wires to hang it and a power cord that will work in your part of the world. It draws 540 Watts and will need 4.6A at 110V or 2.2A at 240V.
Customer service and warranty
G8LED offers a 90-day money-back guarantee with a 2-year warranty on the G8-900. They service the lights themselves if there is a problem.
Advice on growing cannabis with the G8-900
For the vegetative cycle, keep the panel on for 18 hours a day. This mimics summer and encourages your plants to grow so you can clone them. Let them soak up 18 hours of light a day for 4 to 6 weeks. When you start to see signs that flowers are coming, you’re ready for the next stage.
For the flowering cycle, leave the lights on for just 12 hours a day. In 2 weeks or less, you should have flowers blooming. You can add an all-red grow light at this time if you like. The flowering stage may last for up to 8 weeks.
During the flowering stage, lightly fertilize with less nitrogen and more potassium and phosphorus. You’ll save more money with LED grow lights because you’ll need less fertilizer than you would with an HPS or MH light setup.
When you want to harvest, be patient for the cannabis to finish flowering. Wait for the pistils to enlarge and change from white to reddish-brown.
