Finding the best 600 watt LED grow light is one of the most important and difficult things for our grow room. A major issue arises when you are not fully aware of which type of light to install. Also, it’s important to know what maximum amount of heat is acceptable to grow your plants. You can harm your plant or its taste if you don’t know what you’re doing.
These factors are important as they are vital for the growth of your cannabis. You will find some 600W LED grow lights online being compared with HID or HPS lights. But, the most important thing is how budget friendly these lights are when compared to others of the same wattage.
In the long-run, smart people always go for LEDs as they consume less power and give the desired results. Usually, these 600 watt LED grow lights are perfect for an area equal to a 4×4 grow tent. If you’re using two of these lights, an area of a 4×8 grow tent is perfect.
In this article we will cover the best 600W LED grow light reviews. We go over all features of the most popular ones in various price ranges. You will read about all that we think you should know about.
Things to Consider When Buying a 600w LED Light
Simply using window lighting isn’t enough for your seeds to take root and grow healthily. If you’re gardening in a relatively large indoor space, you need to look for 600W LED grow lights, which will have the proper wavelength for your plants. 600W LED grow lights are horticultural and provide full-spectrum lighting for your plants.
You should always use grow lights for indoor plants because they allow you to maintain the optimum growth temperature inside your grow tent all year round. This is why choosing the right type of LED grow light is essential because getting it wrong could mean ruining your plants.
Consequently, there are a few things you should consider while buying a 600W LED grow light.
Four Key Things to Know About LED Grow Lights
First, it’s much easier to understand what you’re looking for if you have some knowledge about LED grow lights. For example, the following features can help you choose the best LED light for your specific needs.
Type of LED Grow Light
There are three common types of LED grow lights available in the market:
- Spread Style
- Traditional Panel
The Spread Style has two subtypes: Quantum Board and Spider LED. The shape of Spread Style LED grow lights involves multiple small LEDs spread out over a large metal surface or panels. As the LEDs are smaller, they have a lower wattage diode.
Traditional Panels have medium wattage diodes and are more compact than Spread Style LEDs. Chip-On-Boards (COBs), on the other hand, have higher wattage diodes and give off more intense light and deeper penetration into the plants’ covering.
Simply put, when buying, you need to keep in mind the intensity of the light as well as the energy bill.
In regards to heat output, the lower it is, the better the results. If the lights give off less heat, the grow space doesn’t risk becoming too hot. LEDs with higher heat outputs are low in quality as they wear off quickly and increase your maintenance costs.
However, ensure that the heat output is not too low and matches the growing needs of the plants. Light intensity tends to drop the further the plant is from the light source. You don’t need to buy a higher wattage to counter a low heat output.
Simply position the plant properly so that you don’t lose heat energy into the surrounding environment.
Quality of LED Chip
Although they’re expensive, good quality chips are specifically designed to encourage healthy plant growth by releasing precise wavelengths. In essence, LEDs are semiconductors with different ratios for different wavelength emissions.
Therefore, whether the diode is low, medium, or high matters a lot because this determines the specifications of the wavelength. For cannabis, the best quality LED chips are those with low to medium diodes.
Are you using your grow space for all the gardening stages or specific ones such as the flowering stage? This makes a difference because the plant requires different amounts of heat energy in different gardening cycles, i.e., from seeding to harvesting.
Some 600W LED lights come with veg and bloom switches, which makes things easier for you. However, if yours doesn’t, you have to keep an eye on the power consumption of grow light for the growing cycle.
When to Use a 600 Watt Grow Light?
Before buying a 600W LED light, make sure that you need one. It could be that you need a LED light with a higher or lower wattage. Usually, indoor gardeners tend to use 32 Watts LED lights, which have an output of 120-300 lumens. However, this wattage matches the needs of only smaller 1×1 grow tents.
Therefore, the wattage of light you need depends on two things, including:
The Size of Your Grow Space
Measuring the size of your grow space is very important to determine what kind of equipment you need. The higher the wattage of your LED grow light, the more area it will cover. This strongly depends on the brand and type of LED grow light, as the number of lumens outputted by different wattages differs from manufacturer to manufacturer.
However, you can find a rough estimation as follows:
- 2×1 grow tent (1-2 plants): 100 Watts
- 2×2 grow tent (1-3 plants): 200 Watts
- 2×3 grow tent (1-6 plants): 300 Watts
- 3×3 grow tent (1-9 plants): 450 Watts
- 3×4 grow tent (1-12 plants): 600 Watts
- 4×4 grow tent (1-16 plants): 800 Watts
- 4×5 grow tent (1-20 plants): 1000 Watts
Keep in mind that for larger grow spaces with plants over 10, you’ll need to get multiple LED lights.
The Type of Plants
Secondly, the type of plants you’re growing determine the intensity of light you need. Different plants require different levels of heat, which is why the light and temperature you maintain in the grow tent is very important.
For example, marijuana plants require about 200 Watts per 100 grams or 3.5 ounces. With one 600W LED, you can generally grow up to four marijuana plants (depending on your plant training method and the species of marijuana.)
