Best Grow Light Hood Reflector in 2019
Last updated on April 19th, 2019 at 08:36 pm
Are you growing indoor cannabis plants? They need nutrients from light and water. But it’s not that simple. You’ll also need to provide the plants with enough light. LED grow lights are great, but how can you maximize your light coverage? That’s where reflector hoods come in. They maximize your grow light efficiency by ensuring 100% of the light is reflected towards your cannabis plants. It’s important for the plants not only to get light but to also the right amount, intensity, and range.
Indoor plants need 12 to 16 hours of light per day based on factors like whether they’re flowering plants or seedlings. A grow light can provide enough light for your plants. However, you’ll also need to adjust the light intensity, which can range from full sunlight to full shade. I’ve reviewed some top of the line grow light hoods for exactly that purpose.

What Is a Grow Light Hood Used for?
If you already have grow lights then why do you need a hood/reflector? These units are designed to work with metal halide (MH), and high-pressure sodium (HPS) grow lights. If you have a grow room, then you should definitely consider investing in grow light reflectors.
They use reflective materials in order to direct grow bulbs’ omnidirectional light downwards towards your plants. This makes the lights more efficient and reduces how much light is lost. This is especially critical when growing indoor plants since you’ll want to make your light sources as efficiently as possible.
A mistake newbie grows light users make in particular is not making their system as efficient as possible. If you don’t have the right hood/reflector, it can have a negative effect on your crop yield. That’s a bad thing!
A big plus of grow light hoods is both newbies and experts can use them. This makes them more flexible since you won’t have to have tons of experience in order to use the units, for example.
How about if you own grow lights known as compact fluorescent lights (CFL)? In that case, you’ll have to find/use a CFL reflector that’s specially designed.
Various types of grow light reflectors are available. It’s important to know the basics about the different types so you can pick the best one for your wants and needs. There’s more on that later.
Besides the different types, you also have different sizes and shapes to pick from like Square, Rectangular, and Parabolic. Sizes include Compact and Large.
The different combinations of these shapes and sizes change the light’s footprint including intensity and area. Some examples include tight-focus, wide, and less intensity.
This is another issue to consider when picking a hood/reflector. Different manufacturers use various kinds of reflective materials. There’s no “perfect” material, so each one has benefits/drawbacks. Make sure to consider these factors so you can make a good decision about the best one for your situation.
How Hood Reflectors Work
Let’s get a little more specific about how hoods/reflectors work. When grow lights give off photons they travel straight until they hit something. In this case, it’s the grow light reflector’s reflective surface.
Different kinds of surfaces are available. They include:
The physics involved with hoods/reflectors is quite complex. The main thing is to pick a unit that reflects a high amount of light like 97%, for example. This makes it more efficient and reduces how much light has to bounce around before it hits the plants’ surface.
There’s another reason a highly-efficient reflector is important. When there’s more heat energy lost it ends up in the grow room, which makes it warmer. That’s definitely a situation to avoid since it will make the area uncomfortable.
Benefits of a Hood/Reflector for Grow Lights
Why should you consider a hood/reflector to begin with? Here are some of the main reasons you should consider investing in one:
If you just use your hydroponic lighting to light your indoor plants, you’d “waste” lots of light. That’s because it would bounce more than a rubber ball off walls and ceilings. This makes you grow light less effective since less light gets to the plants.
It also causes higher energy bills. The longer you have to provide light for your plants, the higher your bills will be. This can be especially tough if you’re on a shoestring budget.
Keep in mind your bills will also be exponentially higher based on the number of plants you have. Each one will be affected by a bad lighting system.
A hood reflector not only makes sure your plants are getting light efficiently. It also helps to ensure they’re getting enough light. When there’s energy lost from an inefficient grow light system, this can affect how much light they’re actually getting.
One example is flowering plants. They need 12 to 16 hours/light daily. This is based on various factors. One is the type of plant you’re growing since some plants need more light while others need less.
Another factor is the efficiency of your grow lights. A hood/reflector can boost the light’s intensity and thus reduce how many hours of light they need. That provides several benefits including light that’s more intense, efficient, and affordable.
Wing vs. Umbrella vs. Hood vs. Air-Cooled Hood/Reflectors: Which is Best?
When picking a hood/reflector for your grow light you should also know which one is the “best.” We’re using this word loosely because it basically means the type that’s best for you. Here’s a summary of the basic options you have:
These are also known as ‘bat wings” and are a good option for small gardens. You can install these reflectors close to plants and they are a good option for newbies.
How do they work? These units include adjustable wings that you can tweak for your grow area size. These units are usually made of flexible aluminum. A key feature of winged reflectors is you can greatly maximize the light intensity that gets to your plants. This explains why these are better than old-school reflectors on the market, which only reduce light.
When using these fixtures make sure to cool the environment with air conditioners or exhausts. Take this step instead of cooling the fixture itself.
These are also known as “parabolic” reflectors. They’re often used in greenhouses for supplemental lighting due to their ability to cover a wider area. This is one of the most popular types of reflectors on the market.
You have two main options. Horizontal reflectors include horizontal-mounted lamps, and the light/heat are directed down to the area under the reflector.
Then there are parabolic reflectors in which the lamp has a vertical mounting. This directs the heat away from your plants.
A big benefit of umbrella reflectors is the plants experience less heat stress when a big area is covered. Another plus is the soil remains fresher longer, and the chance of later nutrient imbalance is less likely.
When you use grow tents the light is reflected towards the plants instead of getting aimed at them. The results seem to be better than standard horizontal reflectors in terms of healthy plants and bigger yields.
While “hood” and “reflector” are used somewhat interchangeably, we’re talking here about the basic hood shape. You can use this type of fixture in gardens of any size. If you’re using it in a big space, you’ll also need to use extra light sources.
One of the main differences you’ll see when picking a hood is whether it’s open or closed. An open-ended hood includes wing reflectors. These are the most popular ones due to the focused light and low cost.
The main drawback is there’s no system to decrease heat. As a result, you can’t place the hood close to plants, which can affect their growth.
Then there are closed hoods. This provides more focused/uniform light than open-ended units. The problem is while these can be plusses, they must be lifted higher versus open-ended hoods. If there isn’t enough venting, the heat can become an issue when using high-wattage grow bulbs.
This includes two main types including the air-cooled reflector. There’s also the cool-tube reflector, which is a version of the air-cooled. These are designed, so heat gets pushed past the glass at the hood’s bottom. These units also have venting holes located on the sides, which can connect to exhaust ducts.
Like other types of systems, there are pros and cons. In particular, you can control the light focus and heat, and place the reflectors close to plants without them getting burned.
How about drawbacks? The main one is air-cooled reflectors need to be maintained regularly. You must clean the reflectors/glass much more often, so the light output isn’t decreased. Another drawback is the unit’s glass panel is able to filter out UV lights, which can be helpful to plants.
The bottom line Is air-cooled reflectors are one of the best options for enclosed spaces and grow tents. Just be ready to shell out more money since this is the most expensive type of grow light reflector on the market.
There’s no question a hood reflector can make your grow light more efficient. It does this by making the light more focused so more hits the plant. Fewer rays bounce around and end up heating up the grow room. The key is to pick one that best suits the plants, lighting, and system you have.
