Your first lesson in LED science (How to make them work)
 
LETTER: But I've been researching some growing forums & people are saying that LED's are fine for supplementary lighting but do not have enough power to grow plants successfully to budding stage by themselves alone. Another comment was that the LED's are fine for vegetative growth, but cannot produce enough light to give the plant sufficient energy to bud up, in any bulk - that the plants produced are spindly. What do you say?
 
REPLY; The simple answer is that they are NOT using enough LED's. Spindly plants are a classic case of light starvation, the solution? Easy, use more LED LIGHT!!
I use 300 Watts of LED and stopped using my 400 Watt HPS. My power saving is 25% and at those power levels LED light creates radically fast growth and stays very cool in my grow tent requiring no ventilation. Growing is thus greatly simplified, no heat, no odor and not a sound. The secret is just to use a LOT of LED's. People are just expecting way to much from a few LED's. In order to get great results using only LED's you will need an adequate amount of light power.
300 Watts of LED power per 10 sqaure feet will give you a very rapid 'Rain Forest Fast' growth and VERY prolific budding I guaranty it!! If any thing we get way to much budding. I have counted over 64 buds and a plant only 8" tall. This happened in light that was on 18 hours and off for 6 hours per day. We never changed the light cycle and the plants always bud profusely giving us almost 100 flowers in the first 90 days. This is the LED effect but ONLY if you have enough raw LED power at your disposal!! Also you need to use 87% red light in order to get this effect. We always use much more red light these days and at much greater light densities. I personally would not use any other light source. I am hooked on LED's!! Be advised you may have to use more LED's than you have been lead to believe in order to the raise those certain varieties of plants that really appreciate lots of extra light. Not all plants are the same, some plants just require MUCH more light. If these Sun worshiping plant varieties DO get enough LED light the results will be absolutely hyper-prolific growth and fruiting like you have never seen before! Save your money on those expensive fertilizers and put that money into extra LED's and you will get much better results!!

Our grow light systems use new wide angle LED's which provide a larger area of light saturation than do other LED grow light systems. Our grow light systems are designed to be water resistant so they can be easily used with any watering system since we use water resistant LED's in a glass casing! Our LED grow lights emit virtually NO thermal (Heat) radiation so plants can grow right up against them without any harm. Gro-Tek is your advanced horticulture solution.

LED grow lights have many advantages over traditional plant growing lights. The LED lights utilized by LED grow light systems are specifically tailored to emit the parts of the light spectrum plants need to flourish. Plants only use about 9 percent of the light emitted from halide lamps while LED's are nearly 98% efficient for chlorophyll production! LED grow lights emit virtually NO thermal (Heat) radiation that can burn your plants. In fact plants LOVE growing right up against the LED's soaking up all of the perfect wavelengths of light being emitted. They also have an extremely long lamp life lasting over 150,000 hours (well over 15 years of continuous use for these newest 3rd generation lights). Many plants grow bigger and faster under LED grow lights than they do under ALL OTHER traditional types of grow lights. LED grow lights will save you time and money and is the wave of ALL future growing to come since no wavelength of light goes wasted! Almost all of the LED's energy is used for chlorophyll production and this is a high technology first for any type of grow lights.

 

GROWING WITH LED LIGHTS (Usually works well for both low and high light plants)
Our solid state grow lights have been designed for one reason: To grow plants effectively and
affordably. And they do, because the most important part of our design process has always been growing plants.
 
When growing tropical and jungle type plants LED's can be used as stand alone lighting but when growing outdoor plants LED's work best when mixed with fluorescent lights like the T5
 
 
Use LED's as a supplement to your metal halide HID lamps by adding more Red or Blue
to the total light in your growing area thus controlling flowering and bulking.
 
Now for plants grown in windowsills some extra Blue light is needed since most window glass filters out most of the Blue light while allowing all of the Red light to easily pass through to the inside.
 
This is why plants grown in windowsills turn yellow due to lack of essential Blue light waves and some critical UV waves. Most Calcium / Borosilicate window glass tends to filter out most the Blue light/UV wavelengths while allowing the Red light to easily pass through and this creates a chemical imbalance in many plants.
 
This is why plants grown in windowsills turn yellow due to lack of essential Blue light wavelengths and UV. Red Light is not necessary for plants grown in windows since Ca/Borosilicate glass allows red light to pass through easily.
 
Plants can be manipulated by LED's too! Providing excess Blue light creates faster greening and stem growth while enriching dark chlorophyll production while excess Red light promotes fruiting, seeding and flowering since the plants think winter is coming. The Sun puts off more red and less blue light in the fall so manipulating plants is VERY easy when you have lights that put off VERY specific wavelengths! This is perhaps the most important part of LED growing,,, the fact that YOU are in full control of the light wavelengths!!! You can force the plant to react to your needs and you can't do that with ANY other kind of grow lights!!! Being able to manipulate the red and blue wavelengths will give indoor growers a new found control over their corps. In the case of growing Cilantro premature "bolting" or flowering is a big problem but with LED's you can just add some extra blue light and any "bolting" instantly stops!!! Try that with HID lighting. As LED's drop in price and increase in power outputs they will eventually dominate all artificial plant lighting.

About the light
 
Specific Frequency Blue Light LED's are not to be used alone.
Blue Booster LED's have a Specific Frequency - Recommended to be used together when using HPS lighting to augment their otherwise low performance in the Blue light ranges. Plants grow faster and taller when they have extra Blue Light plus you can actually triple the life span of annuals to over three years while watching them grow into monstrously large plants! Only having some extra Blue Light can do this for you!
AKA - The "Mother Keeper Light" - Blue light is great for your Mother!! She grows taller making LOTS of cuttings available for you but she never goes to seed since she is instead putting all of her energy into growing taller trying to find that special RED light just over the horizon,, so she thinks.
 
Specific Frequency Red Light LED's are not to be used alone.
Red Bud LED's have a Specific Frequency - Recommended to be used together when using FLUORESCENT or METAL HALIDE lights to augment their otherwise low performance in the Red light ranges. Red light tells plants that it is time to make ' New Baby Plants' Red Bud lights and are used to force flowering while maximizing the weight and potency of the flower as well.

Mounting -

Lumens and Lux are measurements of how bright a light source appears to the human eye only. With Lumens or Lux you can't accurately compare the plant growing capability of grow lights! If a grow light manufacturer rates their grow light output in Lumens then they are only telling you how bright the grow light will appear to your eyes and has NOTHING to do with plant growth since plants only use a tiny percentage of the FULL light spectrum that old fashioned grow lights emit. In fact Chlorophyll is green for a good reason, plants use this color as a type of "Sun-block" to remove 95% of the unwanted and damaging light wavelengths. LED Red / Blue lighting have such narrow bandwidths that plants without green Chlorophyll would actually survive and never be damaged by the LED's perfect and tailor made light wavelengths. Nearly 100% of the light an LED grow light emits is completely absorbed by the plant! LED's can also be left on 24 hours and day without stressing plants since the Chlorophyll does not have to do battle with unwanted light-waves. Under the COOL GLOW of LED lights plants will think they are growing in Alaska, the land of the midnight Sun and plants grow really FAST in an Alaskan summer season!!!

The most accurate unit of measurement for comparing grow lights is in microEinstein's, which measures how many photons of light strike an area per second. While microEinstein's is a much better way to estimate a lamp's plant growing ability than Lumens or Lux but it is still not correct to use it for comparing grow lights because of the tiny band widths of light plants actually absorb. The irradiance power factor or amount of light that actually gets used in plant growth or Chlorophyll production can be factored at a rate of 400µ mol/mª/sec per every 150 LED's average since they have an extra high MCD output. Now remember this rating is 95% growth efficient light!! All other grow lights except LED grow lights emit mainly wasted light energy that does not help the plant produce Chlorophyll. In fact 95% is wasted since plants only use very narrow bandwidths of the total light energy. Rating light output in simple terms like Lumens or Lux is EXTREMELY misleading especially when rating a GROW LIGHT which has a very specific job, like creating Chlorophyll 'a' and 'b' !!!

For best results lots of aluminum foil (shinny side up) should be employed on the walls of the grow boxes.This is a new way for thinking since HID would get way to hot confined to a reflective grow box. With LED grow lights dropping in price and getting more affordable daily we may all have to rethink our growing techniques to keep up with the times. Cutting your electricity bill back by up to 95% may be the best reason of all to invest in a $5.00 roll of aluminum foil.Making reflective grow boxes may sound like a bit more work BUT not having to worry about fires, ballast replacement, heat, burned plants, ballast noise, ventilation, filtration and high electric bills may just make you think about rearranging the way you grow plants! LED's are finally getting more affordable! The time is NOW to get ready for this new emerging world of economic LED growing!
 
 
 
 
Consider LED grow light products for applications where you want tosignificantly
reduce the electricity costs and eliminate the wasted heat of inefficient HID lights:
 
 
Photosynthesis with LED's
 
The nature of light The energy produced by the sun reaches the earth as electromagnetic radiation. Light and other forms of electromagnetic radiation are considered to have both a wave nature and a particle nature. Particles or packets of light (its particle nature) are known as photons - the smallest divisible units of light. The brightness of light depends on the number of photons absorbed per unit time. Each photon carries a fixed amount of energy which determines the amount that the photon vibrates. The distance moved by a photon during one of it vibrations is referred to as its wavelength and is measured in nanometres. specmove Electromagnetic radiation spans a broad range of wavelengths. At the one end of the spectrum of electromagnetic radiation there are gamma rays which have a wavelength of 10-5 nm and at the other end, radio waves which have a wavelength of 1012nm. A very small part of this spectrum can be seen by the human eye i.e. between the wavelengths 380 and 750 nm. This part of the electromagnetic spectrum is called visible light. Almost all life depends ultimately on this part of the spectrum for its energy. Humans perceive the different wavelengths of visible light as different colours. Within the spectrum the longer the wavelength of the radiation, the slower the vibration of the photons and the less energy each photon contains. Thus photons of ultraviolet light, at the blue end of the visible spectrum, have shorter wavelengths and contain more energy than red light and infrared radiation. Sunlight contains 4% ultraviolet radiation, 52% infrared radiation and 44% visible light. Why is only visible light used by plants ? Light and photosynthesis. Chlorophyll does not absorb all the wavelengths of visible light equally. Chlorophyll a, the most important light-absorbing pigment in plants, does not absorb light in the green part of the spectrum. Light in this range of wavelengths is reflected. This is the reason why chlorophyll is green and also why plants (which contain a lot of chlorophyll) are also green. Note in the graph above that the absorption of light by chlorophyll a is at a maximum at two points on the graph 430 and 662 nm. The rate of photosynthesis at the different wavelengths of visible light also show two peaks which roughly correspond to the absorption peaks of chlorophyll a. Plants do not depend only on chlorophyll a in their light harvesting machinery but also have other pigments (accessory pigments) which absorb light of different wavelengths.
 
 
Why plants only use visible light as a source of energy for photosynthesis.
Plants could use the ultraviolet or infrared section of the spectrum for photosynthesis but here is why they don't.
 
Ultraviolet light Each photon of ultraviolet electromagnetic radiation contains too much radiation for most biological systems. Its high energy drives electrons from molecules and breaks weak bonds. It is absorbed by oxygen in the forms O2 and O3 (ozone). The ozone layer of our atmosphere protects life on the planet from high levels of ultraviolet radiation.
 
Infrared light Each photon of infrared electromagnetic radiation does not contain enough energy to do useful work in a biological system. Cells do absorb this radiation but it contains insufficient energy to excite electrons of molecules and is thus converted to heat. Infrared radiation is absorbed by water and by carbon dioxide in the atmosphere.
 
Visible light Each photon of visible light contains just enough energy to excite the electrons of molecules without causing damage to the cell.

When should you use LED Grow Lights

(Light Emitting Diodes) instead of HID?

LED Grow Lights are better suited than high intensity
discharge (HID) lights in a number of situations:

* To put a lot of light on a small space
* For plants that are sensitive to heat or UV radiation
* Reduction of heat output
* Multi-tier gardening
* Areas where space or ventilation restricts the use of HID lights
* Reduction of power consumption
* Areas where the noise generated by the HID ballast is unwanted

Our new line of LED lights is ALL about helping your plants psychologically with key frequencies of light.
We just use tiny amounts of this psychological influencing lights such as
790nm and 720nm Reds plus 385nm violent and 330nm blues called PGS waves.
This is only about sending the plant a healthy Psychological Growth
Signal and does not actually contribute to Chlorophyll production directly speaking
 
The next wave in the technology of 'Correct Indoor Plant Lighting'
will also deal with healthy plant psychology
as much as RAW chlorophyll production which are
actually tied together much more than was previously thought.

Why do HID lights look so bright?

The human eye is very sensitive to light in the yellow and green regions (500-600 nm). HID lights produce a large amount of yellow and green light, so they look very bright to the human eye but all of this blinding glare is very deceptive as your plant will not use any of this bright 500-600 nm light for growth.

WHY LEDs MAKE BETTER PLANT LIGHTS LEDs vs. HID Plants do not use all parts of the spectrum equally. This is because photosynthetic pigments like chlorophyll and carotene absorb light very strongly at particular wavelengths. Using the right colors in the proper proportions, nearly any desired spectrum may be produced with LEDs.
Here is a graph above shows how the spectrum of LED Grow Lights is very close to that of the absorption spectrum of chlorophyll, a plant's primary energy collecting pigment. Also, the peak of the spectrum of our grow lights coincides with the peak of the photosynthetic response curve. This ability to match spectrums allows LEDs to produce high growth yields.

ADVANTAGES OF LED PLANT LIGHTS LEDs vs. HID

Long Life! - The useful life of our 3rd generation LEDs is 150,000 hours plus burning 24 hours a day! This is called the 'Alaskan Summer' LED growing method is the best way to grow with LEDs! During this 24 hour per day "GREENING" or growing cycle you also add extra CO2 into the grow room. When you need flowers or fruit to appear simply cut the light cycle back to only 12 hours per day. If you prefer growing using only the LED lights on 24/7 and need flowers or buds your can force fruiting using the
 
Energy Efficient - Save 95% on your power bills over HPS / HID lighting. Also consider all of the other reduced power consumption caused by blowers, filters, air conditioning and the usual repairs like ballasts, transformers and over heated bulbs, etc.
 
Better for plant growth - Plants can use nearly all of the light emitted from LED lamps. Wasted energy in metal halide lamps can be calculated in not only efficient use of the light wave lengths but also by massive losses of just wasted HEAT energy! LEDs are just warm to the touch. LED lights produce very little heat. The temperature of our growing areas is controlled by normal residential AC/heating and a ceiling fan. In most situations, no special ventilation or air conditioning is needed.
 
Reflective surfaces -
Use lots of reflective mylar or aluminum foil in your grow room. Cover every last inch including the floor and ceiling. Never allow the light to hit a dark area like soil, cover it too!! Light moves at 187,000,000 miles per second. That means if you have a dark spot ANYWHERE in your grow room the size of a 'quarter' it could actually absorb 25% of the light!! Making sure that every square inch of your grow room is made reflective should become an obsession! When it comes to reflection there is no such thing as "GOING TO FAR". When its done right plants will reward you with explosive growth! It's that important!!
With HPS or HID you can't use that much reflective foil in tight quarters due to the heat build up. Having a 100% reflective grow chamber is the secret key to creating Explosive Growth with all 'cool-light' emitting growing lamp systems.

Control Over Your Plants - The most important benefit to LED light is that you have full control over the wave lengths of Red and Blue light ! The amounts of red and blue light can be precisely controlled. Light can be placed exactly where you need it most. I have placed a Red LED right against the surface of many plants actually touching the areas most likely to produce a flower including orchids, and few days later flower buds started to form! Amazing!!! The level of growth manipulation and control that LEDs can offer the grower are only just now being barely explored. We have manipulated tiny seedlings with excess red light and in just weeks watched them burst into flowers. We have controlled annuals with excess Blue light into thinking summer was never going end and made the last for many years while turning them into monstrously large plants! LED growing is in its initiatory period and much more will be learned in the exciting years to come!

Distance - Just keep the LED's at least 6" away from the plants for best results. If the LED light gets any closer than 6" weird stuff can happen. The leaves could start to grow in curls and spirals and flowering could start very rapidly!!!!! I have experimented with CLOSE PROXIMITY LED growing and the plants do really wild things, its kind of fun to see and it does not hurt the plant! I have had flowers start growing upside down when growing right up against the LED bulb. The plants love it but they can grow strangely when very close to the LED's. For best results 12" to 16" away from the plant is the best. Also plants can go through LED shock. The light from an LED is so potent that many plants may possibly not grow for the first two weeks when you initially put them under the LED light for the first time. Think of it as over fertilizing a plant,,, to much of a good thing is not good. To avoid LED shock you can start by putting the light about 40" away from the plants and moving it closer ever few days until its about 12" to 16" away. LED shock is not fatal but the plants undoubtedly think they have seen the 'LIGHT GOD' and kind of freak out for a little while if you put the LED's right on top of them all of a sudden.

Plants Stay Cooler- There are two types of plants, those whose chemistry works better in hot weather, like corn and wheat and those who like it cooler and more temperate environments, like the plants you'd choose to grow indoors for instance. Most cooler growing plants shut down when it gets too hot to avoid losing more water than they can bring up from their roots. The LED Grow Light gives your plants all the light they need, without the heat of conventional grow lights, letting them grow quickly at room temperature.

Good News for Terrariums and Other Plants Grown "Under Glass"- Plants with high humidity requirements, like African Violets, ferns, and many carnivorous plants, are commonly grown in Terrariums, also called Wardian Cases. Unfortunately, the combination of high humidity with the heat from most light sources, either the sun or conventional grow lights, causes a great deal of condensation on the inner surface of the glass, obscuring your view of the plants inside. By using LED Grow Lights to light your Terrariums no heat is added so the glass stays clear of condensation. Some seedlings with very high humidity requirements are grown with glass covers over their pots for a period of time. Getting enough light to these plants is a challenge, but not if you use an LED light!! The LED Grow Lights emit so little heat that they can be placed directly on top of the glass or plastic cover if desired.

Enjoy Delicate Blooms Longer- Flowers are very delicate, as can be seen from the spotting and edge burning they get outdoors. Richly colored rose petals fade quickly under the summer sun. This is not true when flowering plants bloom indoors under the LED Grow Lights. Miniature roses have been grown with LED Grow Lights with blooms that were picture perfect and unblemished, with some varieties having flowers that lasted for six months without change under blue only LED light. For those of you growing flowers for perfume oils then you really need LED lights as they can increase the potency of your flowers oils and resins dramatically!! An LED light is the only type of light that can be placed within touching distance of your flowers and not burn them. Emails from many loyal customers have reported potency increases of over 600% when the blooming flowers where exposed in ultra-close proximities of LED light radiation.

 
Economical - Low power consumption, high efficiency and cool operating temperatures make LEDs a cost effective choice for your indoor growing needs.
 
Peace of Mind - Besides drastically reducing the chance of burning your plants or even burning down your house, using LED grow lights can also keep the cops away. Gro-Tek does not by any means endorse the growing of illegal plants, in fact we discourage it, but another advantage of our LED grow light systems is that you will never have to put up with the inconvenience of having the police knocking at your door asking what you are growing inside. If you grow Orchids in a residential neighborhood you already know that this is what happens! Police use thermal imaging technology to search for people growing illegal plants indoors. (Police also scan through the power companies data-bases looking for abnormally high power bills too). Our grow light systems are undetectable to thermal imaging because they emit virtually no thermal radiation and use very little power. No one likes the police knocking at the front door especially when their only growing Orchids!

Gro-Tek grow light systems are intended for growing legal plants only. Do not ask questions about growing marijuana or making mushrooms fruit! They will not be answered. These lights are to be used for growing herbs, spices, vegetables and all flowers indoors which eliminates the need for pesticides offering great a organic quality to your plants.
 
Always use a surge protector when using LED lighting!!! No warranties will be honored on systems not protected with surge protectors!
