Do it yourself – COB LED Grow Light Methods

Now, we are going to say something more about COB LED grow light methods and how to grow a perfect cannabis plant. We know that every cannabis plant grower wants a healthy, big, and beautiful plant, therefore, here are some ways how you can achieve that.

  • Make sure to get the right lightMost of the people don’t pay attention to the quality of the lamp and their specifications. Now, in order to get the best cannabis plant, you need to focus on the quality of the light that you will use. We suggest the blue and red lights or lamps with the full spectrum 380-780 nm. This way, you will definitely provide much-needed treatment for your plant.
  • Position the lights correctlyThe light’s position and distance from a plant is important for growing healthy and big cannabis plants. We suggest to place lamps a little bit close, but not to close, about 50cm away from the plant will do the job. This is important because some lamps have poor cooling systems and the heat will damage the plant.
  • Consider more lampsIf you want to get more cannabis plants, it is only logical to get more lamps. Therefore, you can use those lamps to create a sunlight-like area to provide your plants with the needed treatment. Also, you need to be patient and wait for the plant to grow, don’t add more lamps onto one plant since that will do almost nothing.

Consider COB LED fixtures with adjustable spectrum output

Most of the COB LED lights have wide spectrum that provides almost similar light to the sunlight. But, not all of them have the ability to adjust the spectrum output. This option will come quite handful when the plant changes stages and phases of its growth. With this, you will be able to provide your plant with the similar growing process as it were growing in the nature.

Cooling systems are important.

Every COB LED light has some kind of a cooling system. Why is that important? Well, without a cooling system, LEDs will last shorter and your plants will be damaged from the lights. Now, in order to get the healthy plant, you need to have a lamp with good cooling system. Most of the lamps have UL fans and heat dissipation features that come quite handy for every occasion.

Get COB LED fixtures with constant driver circuit

This will only ease the whole process of plant growth. You will be able to rest your head when you have a lamp with constant driver circuit. Most of the lamps have a proper LED driver that supply a constant current and it regulates the intensity of the light. Also, this is in a close connection with the temperature since light produce heat. Good LED circuit driver have ability to adjust the temperature of the light correctly.

Know what you want to grow

Since there are lots of different types of lamps, especially those with the COB LED grow lights, it is very important to choose the right lamp for the right job. Namely, most of the COB LED lights are convenient for indoor use, but some of them are better to be used in places like green houses, gardens, and other. The best way to know how to choose the right COB LED light, is to know where it performs the best.

What about the cost?

Well, almost every COB LED light is high initial investment to begin with. But, if you look for more cost-efficient COB LED lights, then don’t look at the price, look for the ‘’power saving’’ features. Namely, there is a big number of COB LED lights that are expensive at the beginning, but turn out to be a pretty good investment at the end. The lamps with more lights and less power are definitely the best way to save a lot of money through the whole process, but in the end it they don’t cost a fortune per se.

All in all, without high initial investment, you won’t be able to get the COB LED lights, but it pays off at the end, that we can guarantee you.

COB vs. Other LED Grow lights

I guess you already know, how crazy I am about COB grow lights. However, it doesn’t mean I am being biased. For proving that I’m not biased and COB rocks, here is something that I hate to do!

Why do I hate? It because I like all kind of LED grow lights and respect their effort. But, COB is something that just touched my heart. So, that’s why I hate to make a comparison.

As you already know why I hate comparing COB with other grow lights. That’s why I’m doing it differently. I am not doing any head to head comparison. Instead, I’ll tell you about all the varieties pros and cons. So, you can keep gathering bits of knowledge without hating any grow light. So, let’s get into it!

HPS Grow light

HPS grow light one of the most famous grows light in the market. It is known for its perfect and stronger light intensity. It has short light spectrum, and it consumes high-heat. It is quite large. It can run up to fifty thousand hours. It isn’t that expensive. According to the price range, it is suitable for intermediates.

CMH grow light

When it comes to high indoor grow lights, CMH is something that we see in the list. It is known for its extended spectrum. But the light intensity of it isn’t that high. It doesn’t produce a massive amount of heat, but still, it’s quite big. The lifespan of it is around 20,000-25,000 hours which isn’t that bad. According to the pricing range, it’s also perfect for intermediates.

CFL grow light

When you’re looking for something within the low price, CFL grows lights are first in the list. It has low-level light-intensity and tiny light spectrum. As it sounds like less powerful, it produces less heat too. It is small in size. It can perform 7,000 to 12,000 hours. According to the price range and configuration, it’s good for small growers.

MH Grow light

Are you looking for something average? Then MH is something that suits your requirement. CMH doesn’t have deep light intensity, but it has a high light spectrum. It is large and consumes the right amount of energy. For a reason, the MH light produces more heat. It can run up to 12k to 17k hours. It’s available within an average price range.

COB Grow Light

COB light is something that suits all the growers who are looking for the best product of the market and ready to spend the right amount of bucks too. It provides higher-density light and pure full light spectrum as well. As COB is a modern lighting technology, it consumes and uses all the energy, and that’s why it produces less amount of heat. It’s small in size, but still, it has a fantastic lifespan of 50k to 60k hours. It is quite expensive but deserves every penny of the money.

Now, the ball is in your court. You decide, investing in a COB grow light is good or not!

Confusion cleared: COB vs. SMD

Am I a hypocrite? Well, no! SMD light has some similarities with it, but COB is the updated version indeed. For saving all of you from buying SMD grow light by mistaken, I am writing this. Still, I don’t discourage people from getting SMD. SMD is good too. So, here are the differences between COB and SMD.

  • COB has more LEDs in it which SMD doesn’t, even in the same size panel.
  • COB light has higher intensity, more profound and stronger brightness in it.
  • COB isn’t bulky where SMD is.
  • COB produces less heat than SMD.
  • SMD permits you to change the colors where COB doesn’t.
  • SMD has a better spectrum and lightning coverage.
  • SMD has better penetrate rate.

So, these are differences between COB and SMD. COB and SMD’s looks quite the same, and that’s where all the confusion starts. However, COB and SMD aren’t the same things. So, before getting a COB light check wisely.

Conclusion

In the light of everything we said above, we can only add that every one of these COB LED lights that we discussed are definitely worth the money and you can benefit a lot from them. Anyhow, the best way to know which one to choose is widely explained in our buying guide, so there should not be any problems with that.

However, if you plan on growing a cannabis plant, then having one of these lamps will definitely help. They all provide great treatment for the cannabis plants and they are all equally convenient for indoor use. With any complicated effort or troubles, you will be able to benefit a lot from the lamps that we discussed. Choose your favorite and get it now!
