Your reflector plays a much bigger role than you may realize. Sure, you know that it redirects wasted light back towards your canopy, rather than illuminating the walls and ceiling of your room and tent.
But, there are some huge differences between cheap hoods and the best grow light reflector.
If you are paying for electricity, the equipment to setup your grow, and putting serious effort into this, you should really be getting the most out of your hood.
In this article, we are going to cover everything you need to know about buying a reflective hood, including the best grow light reflector currently on the market.
We’ll cover the different types, and help you choose the right one for your grow light setup.
Why are reflectors useful in a grow room?
Unless you are using LED grow lights, you’ll need a reflector. More often than not, your fixture includes one, so you may not even think about it.
But you need to replace your reflector every so often, which is the whole purpose of this article - helping you choose the right grow light reflector hood.
Before we get to that, though, let’s cover why you need to replace yours every so often.
Why you need to replace your grow light reflector just like your bulbs
You replace your bulbs every so often, so why not replace your reflectors? Sure, cleaning them is an important task and can certainly prolong their life.
But, cleaning only does so much. At a certain point, you are better off buying a new one.
Some factors in your grow room can affect how quickly your reflector loses efficacy and will need to be replaced. One example of this is growers using coco as their media.
This is a great media, but it creates a lot of dust. This dust rises and coats the walls of your tent or room, along with your bulb and, that’s right, your reflector.
What are the different types of grow light reflectors?
There are a few different types of grow light reflectors. The main difference between these is shape and function.
The most common and useful type is the air cooled reflector. These are distinguished by the opening on each end of the hood, which is where you would connect your ducting for your ventilation system.
The purpose is to help expel any heat building up within the hood, over your canopy. This not only improves the grow room environment, but helps preserve the life of your bulb.
There are also non-air cooled reflectors, which have the same shape and style as the air cooled reflectors but without ventilation ports.
Another style of reflective hoods is the wing style. As the name suggests, these have two wings - this design also helps dispel built up heat, but not as actively as an air-cooled reflector.
Finally, you have the parabolic reflectors. These are shaped sort of like an umbrella, and are much less common than the aforementioned types of hoods.
Now, let’s get into what we consider to be the best grow light reflector, and the criteria we use to choose this.
What makes the best grow light reflectors better than others?
Metal type is the biggest determinant in how effective and efficient a reflector will be.
When you are shopping based on price and looking for a cheap solution, you are going to get a cheap metal, such as plain old oxidized aluminum or anodized aluminum.
These create plenty of issues in the grow room, including hot spots, loss of light, and heat buildup.
Equally important to the amount of light a hood reflects, is how well it maintains that reflection over time.
Cheaper metals will start to lose their reflection quickly, leading to light being absorbed by the reflector rather than reflected.

Now, we are going to cover the best grow light reflector choices of 2021.
Sun System 8" Double-Ended Air-Cooled Grow Light Reflector
