Dorm Grow LED – Frequently Asked Questions
G8LED LIGHT SELECTION
Yes! G8LED grow lights have been designed to be versatile and can be used for both vegetative growth AND flowering. One light will do both! Add a 90 Watt Red Flower Booster light next to your main panel at the start of flowering to increase the intensity, ratio of red wavelengths and get the maximum yield.
Use the G8-240 BLOOM or G8-450 BLOOM if you have separate veg and flowering areas and want a light for flowering only. The Veg/Flower lights can be used for both veg and flowering (with the addition of a 90 Watt Red Flower Booster). With the BLOOM Only light there is no need to add the 90 Watt Red Flower Boosters because it has a higher red ratio compared to the Veg/Flower lights. The BLOOM Only light can also be used alongside HPS bulbs to reduce total heat and energy consumption. A 450 Watt Veg/Flower light and one 90 Watt Red Flower Booster will have the same ratio as the 450 Bloom light but will have more wattage, intensity and flowering power due to the addition of the 90W light.
The optimal way to use LEDs is to have them in the grow room during both vegetative growth and flowering. If you introduce LEDs to your plants in the middle of their cycle, they will need a few weeks to acclimate to the source of energy and will not give the best yield possible. If you used a different light source during veg, include it along with the LED during flowering. For best results, start and finish with LED grow lights.
Yes, but it is best to start and finish with LEDs to take full advantage of the many benefits of growing with G8LED. Another option is to combine G8LED with HPS during flowering.
The price and coverage area will be very similar to either one G8-450 light or two G8-240 lights. If your grow area is about twice as wide as long, then two of the smaller lights will cover this area better. If your grow area is closer in shape to a square, the larger light will be ideal for this setup.
Distance to hang G8LED Grow Lights from the top of the plant canopy:
As your plants grow and reach for the light, raise the light to keep the distance between the plants and light fairly constant. If you want the plants to stretch, continue raising the light as the plants grow. The plants will reach for the light source and grow taller. Stop raising the light when you do not want more length or when flowering. For shorter, bushier plants decrease the distance. If you keep the distance fixed, the plants will find an equilibrium height and grow wider and denser. If the light is too close it may be too intense and stunt growth and create discoloring. Follow the recommended distances and adjust as necessary. The distance can be kept constant during flowering. The 90 Watt Red Flower Booster is added at the same level as the Veg/Flower lights when the light cycle is changed to 12-12.
This is the most frequently asked question from our customers. G8LED lights have infrared (IR) and ultraviolet (UV) diodes, which sometimes appear to not be on. The IR diodes are not visible to the human eye but are necessary for stem strength. The UV diodes increase trichome formation and are a very dull blue color.
No, the 90W Red light does not have to be centered because it is a supplemental light to the full Spectrum G8LED Veg/Flower Grow Light. Keep your Veg/Flower Grow Light centered and add the 90W Red on the side, angled or on the wall.
Use a surge protected power strip or voltage regulator with your lights. Avoid connecting too many devices to the same power outlet. When operating your light make sure your grow room does not accumulate too much moisture to cause water droplets to form in the lights. Do not spray around the lights. The lights are electrical devices and should not get wet.
Yes, all G8LED lights (except the 90 Watt Red Flower Booster) are made with 3Watt chips. The 3 Watt chip is the ideal size for indoor plants up to 5 feet tall. The 3 Watt chip is more stable and efficient for indoor growing than larger diode sizes. The 3Watt chip allows for a more dense network on the diodes board which gives more intensity per square inch of the light. The 3Watt chip size also outperforms smaller diode sizes.
The 5Watt and 10Watt diodes give off significantly more heat and require larger spacing between diodes placed on the LED panel to avoid thermal breakdown. The result is bigger, bulkier, heavier and more expensive lights to do the same work. The larger diodes do not allow for as dense of a network of diodes needed for Optimal growth. Bigger isn’t always better when it comes to LED grow lights. Click here to compare 3 Watt vs 5 Watt diodes.
Furthermore, the larger chip-sized are less efficient and have low output power. For example, a light made with 120x 10Watt chips is called a 1200Watt light, but the output power is only 320Watts. Each 10Watt chip is highly inefficient and only outputs 2.8-3Watts. Lights made with 5Watt and 10Watt diodes are inferior in design and performance to the ideal 3Watt chip size for indoor growing.
LED grow lights with a Veg/Flower switch turn on/off the blue and red diodes, switching back and forth between these settings. With this kind of a design, only some diodes will be on at a given time. G8LED has designed the Optimal 8-band to work for both Veg AND Flower so the entire light, with 100% of the diodes can be used for both stages of growth, resulting in larger grow area coverage. The G8LED lights are used to their full capacity during both stages of growth and do not need to turn any diodes on or off. Rather than turn red diodes on and off, the 90 Watt Red Flower Booster is added during flowering and is a perfect complement to the Veg/Flower lights.
Add one 90 Watt Red Flower Booster for approximately 10 square feet (3’x3’) of growing area.
LED grow lights with dimmers do not maximize the emitted diode intensity for plant growth hence G8LED does not add them to their grow lights. To get the best coverage from your lights you should have them on at full brightness at all times. Dimming down the light change the light intensity not only results in less grow area coverage but also creates the opportunity for incorrect usage by not using the light consistently and methodically. Use the lights at full intensity and monitor your On and Off schedule to get the best coverage and results from your LED grow lights.
Optical lenses are plastic covers over the diode chip which concentrates the light to a smaller grow area in an attempt to penetrate further. G8LED does not use these lenses as they result in a loss of light intensity emitted from the diodes. G8LED uses 3Watt diodes which penetrate up to 60 inches and thus does not need to concentrate the light with plastic covers which cause the diode to lose 15% intensity due to the refraction of the light.
The stated power draw is the sum of all the diodes. For example, the 600 Watt light has 200 diodes at 3Watts each. However, the actual power (output power) drawn by each diode is always less than 3Watts and varies from 1.6-2.5Watts depending on the wavelength of the diode. The diodes are not run to 100% capacity to protect them from thermal breakdown and increase their lifespan. The best LED grow lights have a balance of output power vs diode chip size.
Dorm Grow LED provides the actual wattage draw (output power) for each light on the product detail page. Some companies do not provide enough specifications regarding their products. Be careful of these companies and make a correct comparison when it looking for a LED grow light for your given grow space. For example, a light made with 120x 10Watt chips is called a 1200Watt light, but the output power is only 320Watts.

Thank you. The lights I received from you guys are high quality and were reasonably priced. Your service was astounding. You guys are second to none. Thanks again!
Larry – Evansville, IN
This is my 5th indoor LED growlight I have purchased from G8LED. My grow room is rockin! Just added the flower boosters and the babies are loving them as much as I am. Thanks again for the exceptional service. You really know how to take care of customers. There should be more companies like you 🙂
Dan – Rocky Mount, VA
Just wrote to say that I was totally impressed with my purchase. I was skeptical switching from HID to LED but from day one I could tell my plants liked the lights. They stay beautiful and deep green. I’m now 90days in an I am totally satisfied with my purchase and would recommend them to anyone. Hands down best value on the market.
