Foylon Reflective Fabric Vs. Mylar, Which Is Better

Do Not Use Aluminum Foil!!

Foylon vs. Mylar

Many type types of reflective fabric are commonly used for grow rooms. Some of the more popular choices are the following:

  • Mylar
  • Foylon
  • Black and White Polymer (AKA “Panda)
  • Flat White Pain
  • And even aluminum foil.

Of the above, Mylar and Foylon are they are also the best choices and the type of grow light-reflective fabric most often seen in store-bought grow tents. As a result, I will only briefly do an overview of the other reflective products. I will though do a comparison on Mylar Reflective Sheets vs. Foylon. And, also give you my reasons why you should choose either of the two. Stay tuned and for an overview of all of the above.

Why Is The Proper Light Reflection Material So Important?

To fully maximize your crop yield, the proper reflective material for your indoor growing operation is mandatory. The goal is for your light to hit your plants and not be wasted. Reflective material can account for up to 40% of your marijuana crop yield. Choosing the proper surface for your grow area walls can do wonders for your yield. For example, the correct surface properly applied to your grow room walls can add up to 30% more light for your plants.

The quality of the reflection is measured via a reflectivity rating. The rating is up to 100%, and the higher the rating, the better. A 95% rating does not necessarily mean you will get 95%. For example, (assuming a hypothetical 95% rating), you may get far less than 95% as some light will escape and not benefit your plants. Additionally, suppose the reflection product is improperly installed. In that case, creases, not 100% flat, or has rips in it, you will not get the wanted 95%.

How Can I Figure Light Reflection Value?

The best way to do it is to use a light meter that directly measures the light percentage. After you get the results, assuming it was not acceptable, make any adjustments to the growing area. I.E., Plug up pinholes or even entirely change the walls surfaces.

Grow Tent Reflective Material Review

Five types of reflective material are commonly used for grow rooms, which are the following:

  • Mylar-This is the most popular type of grow room reflective material on the market and is used on many commercial grow tents. It is known for being a highly reflective material.
  • Foylon-Is are similar to Mylar in performance. However, it is much more durable, which makes it more expensive.
  • Black and White Polymer-Is also called PANDA foil/plastic. As you may have guessed, it is black on one side and white on the other side. It is cheaper than MYlar and Foylon. Compared to Mylar and Foylon, it has roughly the same reflectivity at around 80 to 85%. One disadvantage is that it is plastic, which means it can get very hot. As a result, if you use it, you need to make sure you purchase reliable, and top-notch ventilation for your grow room.
  • Flat White Paint– Of course, this is paint and not sheets or fabric. I included it as it can be used for a grow room or grow box or cabinet. It is known for being budget-friendly and also high reflectivity at 85 to 95%. All you do is paint it on the walls of your growing area. The primary complaint concerning flat white paint is that it can’t be used for your marijuana growing tent. However, it is an excellent option if you to use your indoor grow light setup by wih a grow box or grow room.

Avoid Aluminum Foil For Your Grow Room-Aluminum foil has decent reflectivity. However, it is to be avoided as aluminum is more likely to crease, rip, and is overall less reliable. The creases and holes are more also mean that hot spots are more likely to occur.

This article will now examine, in more depth, Mylar, Foylon, and compare the two.

Foylon Reflective Sheets

Folylon is made by Duracote, whose headquarters are located in Ravena, Ohio. Foylon has earned its reputation as one of the best reflective materials you can purchase. Foylon is made up of spun polyester fiber and a foil laminate for reinforcement. It has superb reflexivity at 95%.

Not accounting for the price, Foylon’s durability is what makes it an excellent buy. Foylon is thicker and significantly more resistant to ripping and tearing than any commonly used reflective material. One downside for Foylon is that it generates substantial heat. (So, does Mylar) As a result, you will need to make sure that you have a quality ventilation system.

Using velcro on your Foylon sheets is an excellent practice as it will allow you to easily replace and clean the sheeting.

 

Reflective Mylar Sheets

Reflective Sheets

Diamond Shaped From Vivosun

IT was originally developed by NASA and is now manufactured by DuPont Teijin Films. It is the most popular reflective material on the market and is used on many of the most popular commercials grow tents. Many of the leading growing tent manufacturers, like Gorilla, use this material. It comes in one or two MM thickness and can be purchased in either sheets or rolls. Its known for having a refection ability of 95% is excellent.

Its biggest downside is that, compared to Foylon, it is prone to tears and rips. It’s recognized as having conduction that, if unchecked it will seriously damage your crops. So, excellent and reliable tent ventilation set up is essential for this highly reflective material.

Not All Are Equal

As it does not reflect as well, do not make the mistake of buying non-textured or smooth Mylar. Textured is superior to its smoother counterpart as it reflects light better and also is more durable. Diamond-Shaped is the most common for grow lights and it has the best light reflection.

Foylon vs. Mylar Reflective Materials

As far as performance, Mylar is quite similar to Foylon grow room fabric. Foylon does have slightly better reflection qualities at 95% to 100%. However, there are a few differences that you should know before you decided to purchase either reflective material. I will summarize each of these differences below and give you my thoughts on each.

Reflection Ability

Foylon has 95 to 100% reflectivity and Mylar is at 90 to 95%.

The better reflective ability is definitely a plus for Foylon. The average grower probably wouldn’t notice much difference between 95 and 100% reflectivity. But for the serious grower, that extra 5% can mean the difference between growing an award-winning strain and having plants that are average. That extra 5% grow light intensity will likely make little to no difference for marijuana plants grown by novice gardeners.

Popularity

Popularity doesn’t necessarily mean quality. Under most circumstances, popularity does mean more availability. Here, Mylar is tons more popular than Foylon. As a result, you can easily purchase it at a local store or Amazon. On the other hand, Foylon isn’t available on Amazon. Additionally, you will have a hard time finding any grow tents that use Foylon. So, if you want the highly reflective Foylon, you may need to order a custom-built grow tent or make one yourself.

Durability

This is the main reason why you would choose Foylon over Mylar. One of the major complaints of Mylar is that it tears quite easily as the sheets are quite thin. Foylon, with its spun polyester fiber reinforcement, is known for being considerably more durable.

Durability is a definite plus. But, as Mylar is relatively cheap and easy to get, a lower price isn’t as crucial as you might imagine.

Price

With Foylon, you will definitely pay extra for the extra durability and its higher reflection ability.

Final Thoughts

Good Enough

Good enough is not generally considered a compliment. For Mylar, It is a compliment. Mylar sheets are good enough for both consumers and highly respected grow tent manufacturers. Both high-end and budget, manufacturers use this material. One example is the Gorilla. Gorilla, which has an excellent reputation and excellent reviews, uses Mylar diamond reflective sheets on even their 2k+ product. Additionally, Vivosun, who makes quality budget-friendly grow tents, uses Mylar.

Both Gorilla and Vivosun make quality tents. Therefore, it is highly unlikely either would use substandard reflective sheets in their tents. So, if Mylar’s reflective material is suitable for Gorilla and other top-notch manufacturers, it would likely serve your purposes.

Why Would You Choose or Not Choose Foylon?

The durability of Foylon is a definite plus. However, Mylar is cheap. As such, any rips in Mylar sheets can be quickly and cheaply fixed. So, Folyon’s superior durability isn’t as big as a factor as you would think.

Foylon is an excellent choice for serious growers who demand maximum reflectivity and also maximum durability. Therefore, Foylon is perfect for high-end growers. Foylon is very expensive. But, it is likely affordable for a DIY grow tent.

Conclusion: Foylon is the best grow reflective material on the market as it surpasses MYLAR in reflectivity and durability. Mylar, though, is just fine for most cannabis growers. However, Foylon is also somewhat scarce and also quite expensive. As a result, based upon its premium price and scarcity, MYAR is not a wrong choice.
