Indoor Marijuana Grow Lights

indoor marijuana grow lights

Indoor marijuana growing activities are now becoming more and more popular. The main reason for these things is the wide spreading of marijuana legalization is countries, states, and terrorists. Another is the qualified ease of cannabis growing and trends to the marijuana plants with modern, state of art equipment. Marijuana is beneficial even for aspiring cannabis gardeners searching for a single plant to grow. The species are resilient, versatile, and resistant to infestation and harm. And for the aspiring cannabis users, growing marijuana in your own house could possibly save you a lot of money. You could cut out the intermediary and grow the weed from seedlings to flower and in time to joint. 

Nevertheless, if you are planning to start growing cannabis plants indoors, you just need to choose the right indoor marijuana grow lights. You will not get a good harvest without proper marijuana grow light. The best grow lights for cannabis typically equals the highest quality THC level, so it is important to get the best ones you could afford because there’s a lot of different kinds of pot grow lights available that looking for the perfect ones for your needs is a little bit hard. 

In this article, we will show you a list of some of the best indoor grow lights for cannabis currently available in the market. Others are a little bit costly, some of them are affordable. Despite that, if you use them properly, they will get the work done successfully. 

How do we light our cannabis growing space?

When you plan to set up for indoor marijuana cultivation for personal use at home, there’re a lot of factors to consider if you want to get a great outcome, but one of the most essential things to consider is the type of weed lamps and its power usage. You must bear in mind that everts technology has different benefits and downsides. Specific types of bulbs would offer you the best yields but at the same time, there is a substantial heat source that could cause conflicts to many cannabis growers, specifically those who live in certain warm climates or are only allowed to grow marijuana in small areas. On the other side, other kinds of lighting release almost no heat at all, even though sometimes the high cost of this kind of light, blended with its lower efficiency when contrasted to other types, mix to make them less famous. They are essential to many indoor cannabis growers that could only grow marijuana successfully with the low heat consumption of these grow lights. 

The selection of indoor lighting systems is based mainly on the period of growth in which the plant considers itself (seedling, vegetative growth, or flowering), which dictates the light spectrum and frequency needed. As we have noted, the available growing space seems to have an impact on this decision, as some lamps would also release too much heat for use in lowered areas as well as MH or HPS lights. 

The Right Light Spectrum for Marijuana Plants

When it comes to the color temperature of the light spectrum, marijuana plants would then receive blue light (450-500 nm) throughout their vegetative stage, and red light (610-750 nm) during the flowering season. Many cannabis growers use basic fluorescent bulbs or CFL light bulbs with a blue spectrum when rooting clones and during the first stages of developing seedlings. For plant growth and pre-flowering, most will start using lights with almost the same spectrum although with greater power, like metal halide lamps. This promotes the framework of the plant to become stronger over time, preparing it for plentiful flowering.

Red light spectrums are usually used for flowering marijuana plants, as this is the color range that best copy the sunlight throughout the autumn months, once outdoor marijuana is naturally in flower. In this situation, the most usually used are HPS lamps, progressively followed by LED systems due to its good performance, lower energy usage, and most substantially, low thermal emission, which would be the primary issue with high-pressure sodium (HPS) systems.

On other hand, most of the green light that is reflected by the leaves has no effect on marijuana plants, making it a great color spectrum to choose when cannabis growers want to function on their flowering plants with the lights off, without interrupting and stressing the dark period.

Lighting Systems for Marijuana Plants

CFL and Fluorescent lights

This is the optimal type of light for rooting and sprouting cannabis seeds, as well as the low weight needed throughout these phases, combined with their low-frequency consumption and power emission, make them great for this objective. Classic lighting systems using CFL energy-saving light bulbs or fluorescent tubes (Compact Fluorescent Light) are light-shaped fluorescent lights with such a classic base for bulb plugs. The CFL has built-in ballast, so you just need to screw it to the reflector and plug it in.

Metal Halide or MH lights

If you really want explosive plant growth during the vegetative stage, the Metal Halide lights are among the best choices. Their spectrum is great for this stage, and that we could seek lamps with a much higher intensity than CFL lamps and fluorescent. This type of light bulb requires a propellant to function, which can often be consistent with both MH and high-pressure sodium, the bulbs most usually used for the flowering phase. When you’re using the same ballast for the growth and flowering stage, you should take the wattage into consideration. For instance, you need to use 400w bulbs with 400w ballasts, so on and so forth. These lamps were mostly usually found in 250, 400, and 600 watts.

Metal Halide lamps as well offer outstanding results during the pre-flowering stage of development (first 2 to 3 weeks of the flowering stage) because their light spectrum helps to prevent bending when contrasted to HPS lighting, producing plants with a much more stocky framework, ideal for abundant flowering.

High-Pressure Sodium or HPS lights

Talking about HPS lighting means talking about the most famous lamps in any flowering space, even though LED panels were already slowly making headway in past years. We could even find HPS combined light (dual spectrum) used for both growth and flowering, or specific for this last stage. Traditionally, this has been said it is the kind of light that provides the best actual quality, even though its biggest issue is its heat emission and its spectrum is not really sufficient for growth development. In order to reduce the heat it emits, many cannabis growers used a cool tube beam, air-cooled curved mirrors attached to the extractor, which reduces the room temperature by a few degrees. Normally, you could also locate them at 250 watts, 400 watts, 600 watts, and 1000 watts, with 600 watts being the best in rooms of even more than one sq meter (1,5 m2 roughly).

CMH LEC grow lights

Ceramic metal halide lamps (or ceramic light-emitting lamps) are the latest light indoor marijuana grow lights in the market. With increased light spectrum, lamps such as Nanolux 315w CMH LEC, Lumatek Aurora 315w CMH LEC, or SunBurst 315W CMH LE are becoming incredibly popular due to its superior functionalities and higher yields, which are more skilled than standard HPS systems. You will find both 4200 K and bulbs, and also various fixtures; 315 watts, 630 watts Double Ended, 2x315W. One of the major novelties with context to this type of lamp is the new model and components: the traditional quartz part within the bulb has also been substituted by a ceramic component that offers a much wider range of lighting and therefore increases plant productivity. Both color flexibility and participation are stronger with these lamps, which are also more effective in terms of power consumption than the MH / HPS systems.

LED Panels and cannabis

LED lights are becoming incredibly popular among homegrown marijuana growers as they deliver good outcomes to HPS lights, but with lesser energy consumption and power emission. These lighting systems have improved considerably over the last few years, and now they offer outcomes that were unimaginable only a short time ago. Their major disadvantage is the price of lighting, and even though they are quickly recovered in the electricity bills due to their energy-saving usage, the initial cost is out of the range of many pockets. The major benefit of LED lighting would be that it hardly even produces any heat, and there’s no need for strong air extraction techniques in our cultivation area, even if it is a growing tent or a small room, and we might have to provide all the room with just a little extra heat in the cold season of the year, using heat mats, heating wires, etc.

UV light and Marijuana resin

The use of ultraviolet light in the cultivation of marijuana has been explored for a long period of time. As per the most widely accepted concepts, marijuana generates resin or trichomes designed to safeguard itself from the light intensity and solar UV rays coming from the sun. Even so, most of the experiments conducted out lacked the proper intellectual validity, so it would be early to assure their outcomes in indoor marijuana cultivation. If you want to innovate with this type of light, bear in mind that it should be UVB (not UVA) as well as low-intensity. These rays could also cause skin cancer and serious eye injuries, so we suggest extra caution when using these rays.

Plasma lamps for growing cannabis plants

Plasma lighting systems or HEP (High-Efficiency Plasma) have been discussed for some time. Even though they give greater efficiency unlike HPS lights, they possess different disadvantages, which means that they have not sometimes been used to grow marijuana: the light spectrum is not suitable for efficient flowering; they release UVC rays (very harmful to health); the initial price is high; they produce a lot of heat; they could even cause electromagnetic interference with electronic devices, WiFi signals, etc. if not protected.

Amidst these disadvantages, the benefits of plasma lamps are significant: bulbs are quite long-lasting and maintain the intensity of light over time; they give a very wide range of lights very similar to natural sunlight; they are using less energy than HM and HPS lamps, and they also give excellent light penetration. Even so, some light manufacturing companies have started developing LEP (Light-Emitting Plasma) lamps that, even if still costly, are a far more interesting prospect than they had been several years ago and surely worth looking out for in the long term.

Final Thoughts

You have to plan what takes top priority when growing cannabis indoors. Do you think about the environment, effectiveness, secrecy, and your energy bills? If you are searching for discretion, fluorescent, and LED for your indoor marijuana grow lights, these are the ideal options. HID is one of the best grow lights for cannabis if you are after efficiency. That is when you wouldn’t mind the increase in your electric bill. 

But then again, if you have a grow space of fewer than 5 sq feet, fluorescent is enough when you only have small plants. You could upgrade to a 250 watts HPS as your cannabis plants get bigger. If you have room, the MH light for plants in the vegetative phase as well as the HPS for the flowering stage will work well. Using MH lighting all around is fine, but it will have lesser flowers, more grasses, and lower yields. Options available work best for various approaches, so choose something that feels perfect for you and perform to its advantage. Once you have chosen the right indoor grow lights for cannabis, you can begin growing marijuana. After you’ve chosen the type of soil, your fertilizer choices, and a few other stuff.
