How to pick the best reflective materials for grow room?

When picking a reflective material, you need one that will maximize your light’s reflection across the grow room. Different kind of materials have different reflective capacities and this is an important factor you must have in mind. You need a reflective material that can tend to your needs and the peculiarities of your grow room. Below, we will discuss the most important factors to consider when buying a reflective material for your grow room.

Reflective Capacity

Adequate reflection of light is the main function of a reflective material. You should be very much concerned about your material’s reflective capacity. This tells a lot about how well it can benefit your plants in the long run. For instance, Mylar is arguably the most reflective material and provides close to 100% reflectivity. If you are looking for an option with the most reflectivity, you now know the best material to look out for.

Paint, plastic and aluminum foil materials can also provide up to 95% reflectivity depending on their models. Endeavor not to purchase a reflective material that is prone to wrinkles and scratches. This will bring about dark spots and hot spots. Light concentrates on hot spots while it is absent in dark spots. When these become present in your sheet, it won’t reflect light equally to all areas of your grow room.

The reflective capacity of the option you’re choosing is very important and you must not make any mistake. The capacity of the material to reflect light will determine the health of your plants.

Durability

This is another important factor to consider when purchasing your reflective material. You don’t want an option that needs replacement after just months of use. For instance, aluminum foil can easily wrinkle or scratch and this doesn’t promise a sheet that can last long. Some paints may also wash out in a short time as a result of environmental conditions. Endeavor to buy a sheet made from a material that promises longevity. You don’t want yourself having to make frequent replacements.

Temperature

Before going ahead to buy a reflective roll, make sure you know the temperature of your grow room. There are certain materials best suited for cold environments while there are also materials made for hot environments. You need a reflective sheet that can suit your grow room in order not to endanger the health of your plants. For instance, paint reflective material doesn’t emit excessive heat. This in turn means your grow room with high temperature will not become hotter. If your grow room has a low temperature, a Mylar or Foylon reflective material is your best option. These materials emit radiant heat and require proper ventilation.

Budget

The first things you consider whenever you want to purchase a product are usually the cost and your pocket. You want a cost-effective roll that won’t put a hole in your pocket. You also want it to have high quality. Endeavor to go for a roll that is affordable and doesn’t compromise on quality. If you are going for an expensive option, ensure it’s providing good value for your money. Don’t buy a product that is not commensurate with the price.

FAQs on Reflective Material For Grow Room

Can I Use Mirrors As Reflectors in my Grow Room?

AnswerNo, please don’t. Mirrors are only great at reflecting images, not light. Apart from not being great reflectors, they can harm your plants. They can generate hot spots due to the infrared light they reflect which is heat.

They are notoriously prone to delamination in damp conditions. They are not good options for your plants if you don’t want trouble. This is why you almost don’t see them in grow tents or boxes. It will do you a lot of good to put them in your bedroom or bathroom where they are actually useful.

Is tin foil a good reflector?

AnswerYes, tin foil is a pretty good reflector. It works perfectly when its surface is clean. Impurities of aluminum materials are no good to the foil. They reduce its reflectivity, scatter and raise radiation absorption. Purity should be up to 99.6% at least if high reflectivity wants to be obtained. Other factors like surface roughness, heat rays and smoothness also affect foil’s reflectivity. When purity and heat rays of the foil increase, light reflectance will increase. When surface of foil is not smooth, light reflectivity decreases.

While the tin foil will not reflect much light as mylar will do, it will reflect enough light to effectively aid your plant’s growth. When you put enough space between plants, light from tin foil will reach each of their foliage.

What is the best color to paint a grow room?

Answer: The best color to paint a grow room is white. This is because it reflects more light than silver wall or metallic colored covering. White paint can reflect as much as 75-85% grow lights. There are no bubbles or pockets with white paint so you should be rest assured there won’t be any hot spots. It is made in such way that nuisances like mildews, fungi and molds will not find shelter in it.

Once you ensure the surface you are painting is smooth, with white paint, you won’t have anything like wrinkling. Cleaning a painted surface is also clean.

Conclusion

Gone are those days when you are only restricted to outdoor farming, innovation has now turned things around. You now have the luxury of growing plants indoor with tools that can aid their growth and survival. You would have noticed all the four products we reviewed are of mylar material. This is because of the high reflectivity it provides for the good of plants.

Your plants require plenty light and normal temperature to ensure effective growth. In searching for the best reflective material for grow room, you should go for a product that promises you high reflectivity, super durability, and proper temperature.
