Best Reflective Material for Grow Rooms – An Ultimate Buying Guide

Now that we have sorted you out with some of the best available reflective material for the grow rooms, both the mylar and other variants, it is time we discuss some of the important factors that you need to consider when it comes to buying your favourite reflective material. Aside from the quality of the product, there are a few other factors that one needs to keep an eye out for.

1. Type of reflective material

While there are several types of reflective materials available in the market for the grow rooms, there are a few specific variants that you need to keep an eye out for. For your convenience, we are going to share the different types of reflective materials available.

2. Mylar reflective material

This is likely the most popular type of material in the lot and can reflect up to 95% of the light. These are mainly made with polyester material, one that is extremely durable and doesn’t interfere with the normal reflective process. If you are buying this material, make sure that you have proper ventilation inside the room. But, these are sometimes extremely thin which makes them prone to tear and puncture.

3. Paint reflective material

If you are not a big fan of polyester materials, the paint is the next best option. For this, you can directly use the white paint to ensure faster reflection of the light without any hassle. The best reason why several indoor gardeners prefer this is because of the ease of use and cleaning. The latex material is extremely easy to remove without any hassle. It also doesn’t produce heating inside, which again is a reason why it is so popular.

4. Foylon reflective material

This is an extremely underrated form of reflective material, which is one of the reasons why you normally wouldn’t find this in the market. It has a very similar design to the Mylar reflective material. It is an expensive option, so if you are willing to spend that extra money, you can look into it. It allows 95% of the light to bounce back to facilitate the growth of the plants.

5. Plastic reflective material

Lastly, the plastic reflective material is another factor that stands out in the list of materials. It is made with a black or white polymer that helps reflect 95% of the light to prevent hotspots inside the grow rooms. This one is particularly popular among marijuana growers.

6. Price point

Another factor that you need to consider while buying a reflective material for the grow rooms is the price of the sheet. You want something effective and at the same time, extremely durable as well. Generally, the price varies between $5-$20, so try and stick to that price point.

7. Size 

Last but not least is the size of the roll that you are buying. Since these reflective materials are subject to destruction if left out for long, the last thing you want to do is buy in bulk and waste the amount that you don’t need. So, try and buy one that comes with customizable cutting options according to the size of your grow room.

FAQs

1. Why do you need reflective material for grow tents?

A reflective material is really important for grow tents because when you are using a grow light inside the tent, the light spreads multi-directionally and doesn’t really ‘focus’ on the plant. With having reflective layers all around the tent, the idea is that a majority of this light would bounce from all sides and reach the plant from all angles and from all directions, allowing it to grow better. Some of this light would even reach at angles which can otherwise become inaccessible due to the dense growth. Reflective materials around the inner walls make sure that there is no light-loss that is happening and your plants are getting all the artificially created sunlight that they require for a healthy growth. 

2. Should the inner or the outer layer of a grow tent be reflective?

The inner layer of the grow tent has to be reflective, and the outer layer needs to be made of a thick canvas, that is generally double-stitched to ensure maximum strength. This is generally a darker cloth too, to make sure light just can’t leak out of it. The inner layer, on the other hand, is the one which is being discussed in this article. The inner layer needs to be reflective which ensures that all the light bounces back to the plant and no light is absorbed away by the tent or lost in leaks. Having a very reflective inner layer and a strong and durable outer layer ensure that you are getting the best possible results. 

3. Which is the best kind of reflective material to use inside a grow tent?

While there are a number of materials out there that you can use to line your grow tent’s inner walls with, we suggest making use of the diamond mylar layers. This layering is significantly better than using something like matt white or orca grow layers, as it gives your plants an enhanced and increased lighting. Research has proven that when you use diamond mylar layers, your plants get up to 25% more light than they would without it. However, you’ve got to watch out for the dirt inside the tent as Mylar picks up dirt rather quickly.

4. Where to buy the best reflective material for grow tents?

If you are planning on buying reflective material for your grow tents, we suggest you walk into any store that sells gardening supplies (and especially grow tents). You are bound to find at least some mylar layers over there. Besides that, if you go to specialized stores which provide such layering, you can find mylar layers over there as well. However, instead of checking out store to store and shop to shop, we would recommend you to check out the Amazon web store where you can get hold of a large number of these shiny mylar layers and buy them in just a couple of mouse clicks,

5. Can you grow plants inside a grow tent without using a reflective material?

The answer to this is yes – you can grow plants inside a grow tent without using a reflective material, but excluding that would be a rather bad choice to make. This is because while your plants can grow well even without this layer, the fact is that when you use an inner lining that is highly reflective, your plants get up to 25% more light than they would otherwise get. This ensures that you are getting better yields as well as plants that grow healthier, taller and stronger compared to those that grow in tents without an inner lining. However, most commercially available grow tents today come with mylar lining pre-included in them.

Conclusion

Having a reflective surface for your grow room is extremely important, especially if you have a grow room that is growing plants that need a direct light source. Buying a good quality material is extremely important, so if you were planning on buying a random reflective material and call it a day, you need to change your perspective now. We have sorted out the best ones for you exclusively to check through.
