- LED’s produce low amounts of heat so they will not burn your plants. You can choose to move the lights closer to the plants. Closer lights means more light getting to your plants at a higher intensity.
- Low Heat means less heat stress for your plants which ensure maximum fruit, flower and bud production.
- Low heat produced by the LED lights also means less ventilation and lower air conditioning bills. Watch and adjust your room temperatures as you start using LED lamps.
- LED’s produce the exact bandwidths plants need to grow, flower and produce fruit. Three colors are key to growth which are blue, orange and red at a ratio of 1:1:7 respectively. This technology was originally developed by NASA for use on space missions so the Astronauts could efficiently grow food.
- LED grow lights provide your garden the same amount of usable light and use about a third of the electricity. A 600 watt commercial series LED grow light is equal to about 1600 to 1800 watts of HID lighting. This same light only uses 5 amps to produce that amount of light. A 1000 HID light in comparison uses 15 amps of electricity.
- If you are feeding your plants on a regular schedule with a high quality fertilizer be prepared to tweak fertilizer levels because of the lower stress and heat levels. Plants will use less nutrients for better results.
Being knowledgeable about your LED Grow Light.
- Hang your light in a safe fashion. Use quality hooks and parts to attached into building structure.
- Do not get your light wet. Similar to all other lights water is not your friend.
- Read the instructions and send in your warranty card (or do it online).
- Use a quality light timer rated correctly for the size light(s) you are using.
- Use a surge protector on your light. Rare surges in power lines can happen.
- LED’s can be used for shorter photo periods in some cases. Plants need darkness and rest to grow the next day.
- Do not obstruct ventilation openings on the LED Grow Light. Let it breathe.
- Keep your light(s) clean and occasionally check your fans for dust. Canned air is helpful.

Indoor plant gardens require adequate amounts of light to promote healthy growth processes within plant structures. And while sunlight may not be available in needed amounts, specially designed LED grow lights can simulate needed light energy for plant processes. When deciding between blue or red LEDs, the particular needs of the plant can help in determining which will work best.
Light in its most natural form comes from the sun. Sunlight contains the full balanced spectrum of energy wavelengths so crucial for maintaining life on Earth. According to the Gardener’s Supply Company, plant processes rely on the energy contained inside light to produce food and support the plant body. Different types of light produce various energy wavelengths that affect plant structures in different ways. LED lighting actually sits just below the visible light spectrum, so the energy contained inside LED wavelengths is thermal, or radiant energy.
LED stands for light-emitting diode. This light-emitting feature refers to the degree of heat that radiates from an LED bulb, according to the Gardener’s Supply Company. This form of energy is made up of longer and slower wavelengths than those that form visible light. As a result, living cells actually absorb LED wavelengths, which has direct effects on cell metabolism processes. The use of red and blue lighting for indoor planting purposes combines the thermal effects of LED wavelengths with blue and red energy wavelengths.
Of all the colors contained inside the visible light spectrum, plants are most responsive to the energy contained inside red and blue wavelengths, according to the University of Missouri Extension. Both types of energy play vital roles within plant photosynthesis processes where light energy is absorbed and converted into carbohydrate materials. These carbohydrate materials are then converted into food for the plant. The metabolism processes involved in making plants strong and healthy rely on the energy contained inside blue and red light waves.
The wavelengths contained inside light are made up of photon energy particles. The energy contained inside blue LED light plays an essential role in stimulating and regulating seedling growth processes, according to the Plant Physiology Information website. Chlorophyll pigments contained on leaf surfaces are responsible for absorbing incoming light energy. These areas rely on the energy contained in blue light waves to create the chemical reactions that take place in photosynthesis. Blue light waves also promote the production of chlorophyll materials on leaf surfaces.
According to the Gardener’s Supply Company, red LED light waves help to stimulate overall growth throughout the structure of a plant. When growing vegetative or flowering plants, red wavelengths help to stimulate fruit and flower growth processes. This form of energy is also beneficial in stimulating seed and bulb growth, though a balance of blue light is needed to properly regulate early growth processes. In general, both red and blue light waves are needed for the health and growth of plants, so balanced amounts of both provide an ideal environment for new and established plants.
Coverage area varies widely depending upon many factors:
wattage of individual diodes
shape of the grow light
degree angle of the diodes
overall wattage of the light
. . . the list goes on
Of all of the reasons coverage is affected, the most important is its intended usage. You see, many manufacturers publish coverage areas based on the vegetative stage. This is a very important point. When plants are in the vegetative stage, they need less intense lighting than in the flowering stage. As cannabis growers already know, getting plants successfully through the vegetative stage with LED grow lights is pretty straight forward at this point. It gets tricky when bringing your plants through the flowering stage successfully due partly to the fact that some lights are just not up to the challenge. More importantly manufacturers are eager to show clients a huge savings in electricity (thus justifying the higher entry cost) stating a 90W LED grow light can support a gardening space of 4′x4′.
Let me be blunt here – a 90W LED grow light can support a 4′x4′ footprint but only during the vegetative growth of plants like lettuce, herbs, and some fruits and vegetables. If that is what you are wanting to grow then you will do just fine. For those of you growing cannabis, coverage expectations need to be put in check.
Chlorophyll a, the most important light-absorbing pigment in plants, does not absorb light in the green part of the spectrum.
So as you can see:
Make up of an ideal led panel:
2% UVB Leds for resin and tric production. 380mn
6% Royal Blue Leds 455mn
12% Blue Leds 470mn
30% Red Leds 627mn
50% Far Red leds 660mn
Sunlight contains 4% ultraviolet radiation, 52% infrared radiation and 44% visible light.
I would stay away from amber leds I have seen I studies that show an increase in hermaphrodites.
I will go into Chlorophyll b when I can find the graphic again.
