G8LED 240 Full Spectrum. Award Winning Hydroponics LED Grow Light

This is a full spectrum grow light for both the vegetative growth and flowering cycles and provides intense coverage for 6 square feet (3feet x 2feet) (0,6sq meter-91cm x 61cm) of grow space. This light penetrates 5feet (152cm) past the plant canopy and saves 50-60% on your electrical consumption. The electrical savings will pay for the light within the first year of usage.

With 8 years of research and improvement, G8LED has formulated the most efficient color ratio with 8 bands of the color spectrum from 380nm to 780nm, including Ultraviolet (UV), Infrared (IR), and 6000K white. This is the perfect spectrum, maximizing plant yield per unit of electrical consumption. There are no wasted diodes in colors that are not needed for photosynthesis and yield. Get higher quality flowers with more trichomes and the highest yields per wattage of electrical consumption. This light is made with 3W chips, which are the ideal size for indoor plants up to 5feet (152cm) in length. The 3W chip has the perfect balance of penetrating power and low heat signature, which allows the G8LED growlights to be made in with a very dense network of diodes, maximizing light intensity per square inch and maximizing the yield per watt.

To increase flowering even further, add one 90W Red Flower Booster alongside the G8-240 Veg/Flower light as supplemental lights during flowering. The Flower Boosters will increase flowering size and density further within a few days of adding them to your grow room. G8LED is unique in its design in that the Veg/Flower lights do not require a veg/flower switch. The switch design turns a portion of the red diodes off during veg and turns them back on during flowering. The G8LED Veg/Flower design allows the grower to use the light to its full capacity instead of reducing the intensity and growing capability.

G8LED lights come with our stellar Customer Service, which is the best in the industry. We have been providing excellent service to our customers for over 8 years. We make customer service our #1 priority and get a large portion of our business from repeat customers and referrals. Make the smart investment for your grow room with a high quality G8LED indoor grow light.

G8 LED Tips

During the vegetative state is when you will start to reap the benefits of your LED grow lights. During this period you will save on your electricity bills and get superior growing results if you properly follow the general tips listed in this section. In the vegetative stage, plants need less intense lighting than in the flowering stage.

Vegetative growth is maintained with 16 or more hours of light. You can even keep the plants under 24 hours of light and they will continue to grow in this stage. However, the recommended growth cycle is 18 hours of light during the vegetative growth stage. This light cycle will create an enviornment that mimics the photoperiod in the summer with long days. During the vegetative stage is when you will start to reap the benefits of your LED grow lights. During this period you will save on your electricity bills and get superior growing results. In the vegetative stage, plants need less intense lighting than in the flowering stage. It is during the vegetative growth stage that cloning, transplanting, pruning, and bending are all initiated.

Turn your LED grow light ON for 18 hours a day and then turn the light OFF and leave your plant in the dark for another 6 hours. Your plant will need four to six weeks of this cycle to be ready to start the flowering stage. Pre-flowers are the first indication that the plant is ready to move into the next stage of growth. The pre-flowers grow at branch internodes just behind  the leaf spur in around the fourth week of vegetative growth, when the plant is six to eight weeks old. When you start seeing pre-flowers forming this means that the plants are ready to go into the flowering stage. You can continue to grow in the vegetative growth stage or switch to flowering at this point. The pre-flower looks like a regular female flower with white fuzzy pistils. The pre-flowering can take from one to two weeks. Wait to induce flowering until pre-flowers have appeared. Induce flowering by switching your light cycle to 12 hours of uninterrupted darkness and 12 hours of light. 


Flowering Tips

With LED grow lights we mimic the seasons by changing the light cycle from 18 hours a day to 12 hours. Give your plants 12 hours of uninterrupted darkness and 12 hours of light to induce visible signs of flowering in two weeks or less.  Adding more light to the plants also help give bigger flowers and yield. It is recommended to add an all red 90 watt led grow light at this stage for more robust flowering.

Once you have induced flowering for one to two weeks and flowering starts, it can last can last eight weeks or longer. During flowering growth patterns and chemistry changes in the plants (i.e. indoor growing flowering stages). Stems elongate, leaves grow progressively fewer blades and flower formation is rapid at first then slows. Phosphorus and potassium uptake increase to promote floral formation. Your nutrients should have less nitrogen and more potassium and phosphorus during flowering.  Don’t give nutrients too often as this can cause your plant to get nutrient burned. You should use about 30% less nutrients with LED flowering grow lights as compared to MH/HPS systems. Do not overwater, over nutrient and do not harvest too early. 


Cloning Tips

LED grow lights are great for cloning plants. Proper usage of LED grow lights will multiply the number of plants you have in a methodical and environmentally friendly way. Cloning require only 2-3 weeks in the vegetative state.  Use an 18-20 hour ON cycle for your clone and spray it with water intermittently. As with the vegetative state, when your plants are seedlings the light should be at the recommended hanging distance. As the plants start to grow adjust the light upwards a few inches at a time.
