Cannabis Grow Lights

Cannabis Grow Lights

The best place to grow Cannabis crops is in South America close to the equator the location where the intense sunlight can provide your plants’ sufficient energy to grow to 10 to 15 feet in height.

When the changing seasons while the plant advances throughout its life-cycle, adjustments in made from the color spectrum of the sun as well as the length of each day enable the plant to understand when it is time for it to be fertile.

The flower part stands out as the sexual parts associated with plants. Once the time of year shifts right from Springtime to Fall season, the time comes for the plants to get ready for reproduction.

Because we are going to be taking out the male plants, when this happens, the female plant bud will keep growing, and also their THC material will continuously expand.

You’ll want to make use of a set of two varieties of lighting meant for growing Cannabis.

Cannabis Grow Lights

Throughout the phase of fast vegetative growth, the cannabis plant will be needing plenty of blue-spectrum lighting switched on for most of the day.

Many stores offer these types of cannabis grow lights as daylight lamps.

The color value of lighting can often to be found over the package as color temperature, indicated as Kelvin.

The color temperatures you need for this particular phase of growth are going to be higher, something within the range of 6,500 Kelvin.

For better vegetative development, you will want a minimum of 2,000 lumens per sq. Ft.

Several types of cannabis grow lights

In case your budget is not especially limited, you can get some Metal-Halide (MH) lighting.

This cannabis growing lights are ideal for the vegetative growth phase of the growing process. They can produce significant quantities of light.

MH lighting must have ballasts to be able to function and therefore are higher in price. They will additionally generate far more heat. If you have a small growing system, MH lights could be overkill. In that case, I would suggest fluorescent Lighting.

LED Cannabis Grow Lights

LED is the acronym for Light Emitting Diode. This type of diode has essential characteristics. They come in small size, and collectively they give off light.

LEDs find application in lighting systems like lamps, bulbs, digital timers and watches, remote control systems, electronic devices, and appliances and growing cannabis indoors.

The lifespan of LEDs is comparably longer in relation with other light sources, and they are a highly efficient light source. Applications of LEDs can be both with commercial or personal purposes.

Like for example, in households where one desires to grow cannabis, he can use LEDs as a light source.  Also, in areas where there is not enough sunlight, the light emitted by LEDs is a suitable replacement as a light source.

Based on findings, the light coming from LEDs can boost the growth of cannabis indoors since the artificial light from the LEDs can support photosynthesis.

Advantages Of LED


the photosynthetically active radiation (PAR), which is emitted by LED produces better energy and results, especially in applications of growing cannabis indoors.

The lights coming from the LED accelerate the growth of cannabis because the wavelength of the light emitted by the device is ideal as cannabis grow lights since plants require specific wavelengths of light necessary for photosynthesis.

Studies show that the bulbs that emit white light which was used before as traditional artificial light can prevent the growth of plants, and the same is true with incandescent lamps or bulbs.

With incandescent lamps, almost 80% of heat is produced instead of light, which can be harmful to growing cannabis.

But with LED, however, optimal results can be attained by balancing the right spectrum of red and blue light. That is why LED cannabis grow lights is widely used instead of white and incandescent bulbs.

Energy Conservation

LEDs are efficient and conserve energy. More than 75% of energy saved by the LEDs help preserve and protect the environment in an indirect manner.

As compared with HID lights, LEDs only consumes half. Approximately, LEDs use up only 100 watts of power and last up to 50 times longer than those traditional white lamps and lights.

Usually, the device lasts up to seven years, which is a great deal of savings, both with energy consumption and the cost of replacement. That is perhaps the reason why many people use LEDs and prefer it for domestic use.

Less Heat

LEDs dissipate less heat as compared with HID lamps. The effect of this is that the growing cannabis not be subjected to too much heat, and as a result, no frequent watering is needed, thus saving water and the environment indirectly.

Also, less heat dissipated means that the cooling system would not be taxed to make the room cooler, thereby reducing the system costs for cooling the room.

LEDs are ideal as cannabis grow lights with the high-humidity requirement.

Zero Noise

Unlike fluorescent lamps which make a buzzing sound when turned on, LEDs are silent when turned on. It is another advantage of LEDs over other lighting systems as no unnecessary and unwanted sounds are produced.

Cycling and On/Off Action

LEDs can be switched on and off in a matter of microseconds. These on and off action would not short the life of LEDs as compared to HID lamps and fluorescent bulbs which are known to be a little cranky when subjected to cycling on and off action and sometimes have trouble restarting.

It makes LEDs a great choice as cannabis grow lights as the device can be turned on and off with ease without breaking it.

No External Damage and Deterioration

One characteristic of LEDs is shock resistance. Unlike HID lamps and fluorescent bulbs which can easily break when subjected to shock, LEDs are not fragile.

When fluorescent bulbs brake, there is a danger to humans and the environment as they contain toxic materials. LEDs do not contain such poisonous materials.

LEDs dim slowly, a characteristic called “slow-failure” which is ideal as compared to sudden burning out of light bulbs.

Multi-utilitarian Quality

LEDs consume less energy, come in smaller packages, and maintenance cost less. Those qualities make LED lights as a multi-utilitarian device.

Also, it can be used in a wide variety of applications such as light indicators, illumination, visual signaling, remote controls, motion sensors like that of an optical mouse, and many others.

Wireless mouse, for example, functions on radiation received due to the LED lights (usually red and blue are used). LED lights are also used as a light source for systems such as vision and theater.

Wide Variety

Diodes come in different types. There are Flashing Light Emitting Diodes, Bi-color LEDs, Tri-color LEDs, RGB LEDs, Alphanumeric LED, and many other kinds. Each of the types mentioned earlier has its corresponding feature and characteristic.

Cannabis Grow Lights 1With the numerous manufacturers of LEDs, one must be aware and beware of low-quality LEDs to get the maximum advantage of the device.

Always go for products which are comparatively higher than those that come in cheap price tag but the warranty and the company that manufactures the same is in question, or unknown.

Remember that LEDs lasts for a longer period of time, even under extreme conditions, but it pays to look for the best quality LEDs to avoid future problems and regrets.

Lights for Growing Cannabis

There are two primary forms of fluorescent lighting options which can be useful for growing cannabis. You can find fluorescent grow light tubes. A well-known company that creates grow-light tubes is called Grow-Lux. However, various other manufacturers exist on the market. This kind of marijuana grow lights must have fluorescent lighting fixtures, that are around at almost any hardware store for less than $15, and they are generally simple and easy to construct.

CFL Lights
CFL Lights

Another kind of fluorescent lights that you can use called CFL’s (compact fluorescent lamps). CFL’s goes into regular light bulb sockets. It may let you have more significant production of light. You can buy it in several spectrum ranges. For the vegetative stage, you would like to work with Daylight light bulbs that have a color temperature of 6,500 Kelvin. While lit up, it looks like a bright white-colored light, nearly a blue color. CFL’s would be the option for lumination of a small grow system. They produce minimal heat, and you can combine it with a reflectorized clamp sockets offered by Walmart at as low as $5.00.

HPS Light

flowering stage Lighting

Towards the flowering phase of cannabis growth, the plant is going to grow better using an increased amount of red spectrum lighting, something around 2,700 Kelvin and needs to be switched on only for half a day. The amount of light also needs to be higher too towards no less than 3,000 lumens for every square foot.

High-pressure Sodium light
High-pressure Sodium light

There aren’t any fluorescents out there that offer decent light within this range. On the other hand, CFL’s may get to this kind of spectrum, and they are available as soft white cannabis growing lights. They seem like a mixture of the yellow and orange colors when lit up. Good brighter lighting which functions properly within this range would likely be HPS (High-pressure Sodium) light HPS lights need to have a ballast to operate.

HPS lighting produces plenty of heat. Therefore they should be positioned farther from your crops compared to fluorescent lights.


Lighting for Cannabis

The list below summarizes the advantages and disadvantages of the various lighting fixtures for growing cannabis:

  • Metal-Halide: Intense lighting that creates plenty of blue-spectrum light. Uses a ballast to operate. It is an excellent option for the vegetative stage.
  • Fluorescents growing light: Extended tubes that produce a blue spectrum lighting. Needs a fluorescent fixture to function — ideal for the vegetative stage.
  • Compact Fluorescent Light: Tiny spiral designed tubes which generates red or blue spectrum light. Suit a regular lighting socket. Perfect for the vegetative stage – 6,500 Kelvin or for the flowering stage use 2,700 Kelvin light.
  • HPS: Intense lighting which produces plenty of red-spectrum light. Needs a ballast to operate — just the thing for the actual flowering stage.

The truth is, the sunlight hardly ever changes from a single spectrum to another. It may be useful to make use of the two blue along with red spectrum cannabis grow lights.

Rather than transitioning lighting sources completely, opt for a relation of around 3:1 for either stage.

With regards to your plants’ vegetative stage, make use of 3 times just as much blue spectrum light as red spectrum light and for the flowering stage work with three times nearly as much red spectrum light.

Timers for your cannabis grow lights

Additionally, you will need to have a timer for use on your cannabis grow lights. You can buy timers at any hardware store or Walmart for around $5.

They can be programmed to have different on/off periods, which will simulate day/night periods.

  • For the vegetative phase, you want to have more extended day periods, usually 18 hours on, 6 hours off.
  • For the flowering phase, shorter days signal the coming of fall, usually 12 hours on 12 hours off.

Invest in a timer, because turning the lights on and off becomes a pain, and forgetting can mean the difference between good and inadequate cannabis production.

Don’t worry if this seems a little intimidating. We will remind you of what kinds of lights to use when we start growing.

For a small grow operation, I recommend using CFL’s the entire way through. They are readily available, have a high light output, and you can purchase it in spectrum ideal for either growing phase.

Now that you have most of your supplies, you need to build your grow room.
