HLG first coined the term “Quantum Board” for an LED grow light with the diodes spread out over a large area (on a board). The board style LED grow lights have become very popular almost as soon as they appeared on the scene. Growers are reporting results that may beat even other LED grow lights when it comes to the amount of yield for the electricity used. I was impressed when I tried one myself. It’s probably too early to call it the winner just yet, but it’s undeniable these are some of the best LED grow lights available today!
Grow Space: 2′ x 2′
2.) Traditional Panel
How Far to Keep from Plants: 36″ is the recommended starting distance from the plants.
Now that you have a basic understanding of the different types of LEDs, lets talk about using them for growing cannabis.
3.) COB Style
The “spider style” LEDs are similar to Quantum Boards in that the individual diodes are spread out and tend to be on the smaller side, but they are set on a panel with “arms” like a spider as opposed to a solid board. One very popular example is the SPYDRx line of LED lights. These typically have an extremely high price, but growers who use them swear they get better results than any other type of LED grow light.
Light Emitting Diodes represent the latest technology in grow lights. Although they can cost up to $500 for a single unit, you can find plenty of models that offer the same functionality at a fraction of the cost.
The main reason this grow light is on the list in the first place is its central chip-on-board (COB) LED from Cree, and the ideal color spectrum for weed farming. COB LEDs are more powerful than standard LEDs, which allows them to penetrate deeper into the canopy. They also emit full-spectrum light that weed plants love.

This is not the end of cool features this budget device delivers. Unlike other cheap grow lights, this one comes with the ability to daisy-chain multiple units for a larger grow space. The one thing Growstar shares with other budget grow lights is it’s nonexistent water resistance. This doesn’t mean it’s low quality, it means you should be careful with water around it.
