HLG 650r Pros:
HLG 650r Cons:
The term “quantum board” was first coined by Horticulture Lighting Group (HLG), a supplier of LED grow lights and other growing kits. Since then, other brands have released their own quantum boards with Samsung chips and good drives. And one of them is Spider Farmer, a Chinese manufacturer that offers high-quality LED grow lights.
When it comes to coverage area, the HLG 650r and SF4000 grow lights have different strengths. The HLG 650r is designed for 7×7 ft vegetation coverage and 5x5 ft flower coverage, whereas the SF4000 can accommodate vegetation up to 5' x 5', but only 4' of flowering plants. This means that HLG 650r has a larger coverage area for veg than the SF4000, but the SF4000 has a larger coverage area for flower.
The HLG 650r and the SF4000 both are known for their high efficiency. In fact, there's not much difference between these two grow lights in terms of efficiency. The HLG 650r has an efficiency of 2.84 umol/J, while the SF4000 has an efficiency of 2.7 umol/J. So with these grow lights, expect better results from your plants .
However, the HLG 650r is more pricey than the SF4000. It's actually very impressive how SF4000 can provide the same results as HPS lights but at a much cheaper price. This is probably why it's one of the most popular grow lights today.
When it comes to comparing the spectrum of these two grow lights, HLG 650r has a full spectrum white and 660nm red while SF4000 has white, blue, red and IR (3000K, 5000K, 660nm and IR 760nm). The HLG650r, compared to the SF4000, produces a more intense red light that is better at helping plants grow and produce flowers and fruit.
This means that if you're growing plants with a high flower/fruit yield, then the HLG650r is a better choice. But if you're looking to grow more leafy greens, then SF4000 is a great alternative.
Both the HLG 650r and the SF4000 grow light offer a passive cooling design and run quietly since they have no fans. However, they differ in terms of features. The HLG 650r offers 5 years warranty while SF4000 offers 3 years warranty. The SF4000 is daisy chaining capable, while the HLG 650r does not offer that capability.
Nevertheless, the most important thing to keep in mind is that both the HLG650r and the SF4000 are great grow lights for plants.
They are designed for serious gardeners and growers who want to get the most out of their plants. But if you're just a beginner, then it's best to start with a cheaper option which is SF4000 as it offers great features but at a more affordable price point.
