Maintaining moderate heat levels has always been one of the main concerns of all gardeners who have their own indoor garden.

A large number of grow lights emit way too much heat that can harm your plant. With quantum boards, you don’t have to worry about that.

Quantum boards tend to distribute heat equally over the whole board, in order to make sure there isn’t too much heat in one place.

They are also usually set up with aluminum sinks which keep the quantum board cool enough.

In comparison to other grow lights, whether it be simple ones or LED ones, these boards are a lot more effective.

Some researchers have proven that quantum boards are twice as effective as basic LED grow lights.

They also need a lot less electricity than all other grow lights, which will save you up some money.

Quantum board can be your DIY project too. They are pretty easy to make, and at this point, you can even find quantum board kits in the supermarket which will make the whole process much easier.

What can be a problem If you decide to purchase a quantum board is a fact that they go out of stock very often.

Unfortunately, quantum boards can’t be used outdoors since they won’t survive in either too wet or too humid environments.

COB LED lights – What Are They?

COB LED lights

Chip-on-board lights are commonly known as COB lights. This is also a type of LED lights and they consist of many tightly packed LED chips that are bonded to silicon carbide.

The chips are usually of a smaller size, all situated on one metal board.

What made COB LED lights popular in the first place was their efficiency and life span, which were way better and longer than regular lights, like HPS or MH grow lights.

Don’t forget that they were on the market a lot before quantum boards, so for a long period of time, they were certainly the most popular and effective type of grow lights on the market.

COB LED lights have an extremely high CRI, or Color Rendering Index which means that your plants will be exposed to the light of highest quality that won’t harm them.

COB LED lights can have some problems with heat management since there are many chips located in just one small place.

Problems with heat are very rare, but you have to be aware that overheating can happen. Commercial growers usually add fans to their COB LED lights, but it can be quite an expensive addition if you pursue gardening as a hobby.

Like most of the LED lights, COB lights also have a long life span and can last you for more than 50,000 hours. This means that one COB LED can last you years.

They also don’t require a lot of electricity, so you don’t have to be afraid of large electricity bills.

Unfortunately, COB LED lights have one very weak spot, and that’s the concentration of light.

Since all of the light in COB LED lights comes from just one source, the further away the light bulb is from the source, the less light will be coming from it.

This often leads to so-called dark spots which will lead to some parts of COB emitting little to no light. Long term, this can be very harmful to your plant.

COB LED lights can be quite an investment, but they will pay off shortly since they will last you for years and will save you up a lot of electricity.

People are often skeptical about COB LED lights, but they actually have many good and few negative sides.

As you have already seen, there are many pros and cons for each of these grow lights.

Quantum boards are a new and very efficient technology that is becoming popular in gardening, but they tend to be unavailable pretty often.

They are more efficient than other grow lights and are very easy to use, which makes them a perfect choice for people who pursue gardening as a hobby or are new to indoor gardening.

Unfortunately, their biggest disadvantage is the fact that they can’t be used outdoors since they can function in a wet and humid environment.

If you need grow lights that you would use both indoors and in your grow tent, you should avoid quantum boards because it will double your expenses.

On the other side, COB LED lights are a much older technology, but they are still pretty good and efficient.

The biggest problem is that COB LED lights often have blind spots which prevents them from distributing light equally to all plants.

In conclusion, both quantum boards and COB LED lights are efficient grow lights, but I would always recommend using quantum boards. They are the newest and most efficient technology on the market and are suitable for both beginner gardeners and commercial growers.
