Before we worry about the type of light to use, we should first make sure that we are going to be able to efficiently use the light!
In this article, we are going to reviews different ways to get more bang for your buck in regards to your lights.There is a lot of wasted beams that float right past our bud that we need to reflect back! Use these methods before you spend money on new lights! Always make sure you are getting everything you are paying for! There are different methods you should use according to different factors such as if you travel or not, so be sure to ponder all your options.
- The most basic defense is to paint your grow area with flat white paint, NO GLOSS which reflects probably about 50% of the beams it comes in contact with back to your plant. It is recommend to also use a fungicide when painting.
- Rubberized roofing paint is about 90% reflective and is mildew resistant. This will reflect a fairly good amount back, but we will want something closer if possible since the farther light travels, the weaker it is.
- Aluminum foil is a really cheap fix, but it comes with disadvantages. Since it crinkles easily, you will get less efficiency out of it. Also, it can form hot air pockets which could disturb your plant. This method will not exceed 55% light reflected and make sure to use the dull side to reflect light. Foil is also electrically conductive and a fire hazard when in close quarters with lighting fixtures.
- Mylar is similar, except that it is thicker and less crinkly, which can also come infrared, meaning that helicopters will not be able to see your heat signature from above, spotting the grow room and these are also tear resistant. This polyester comes in varying thickness and retain 92-97% light reflection.
- Foylon is slightly less reflective, but is less susceptible to damage and easier to clean so tends to be better in the long run. Both reflect radiant heat around 85% so a fan is most likely necessary when using these.
- White/black panda plastic is useful when you are building a temporary grow room and do not want to mess up the walls. The white side is 75-90% reflective and a 6 mill thickness will ensure maximum blockage and durability along with the black side blocking light as well.Keep away from light, however, or it will melt.
- Styrofoam or polystyrene foam sheeting is excellent for harsh environment grow rooms that require extra ventilation and assist in keeping temperatures down. It is approximately 75-85% reflective and will not create hot spots.
- Emergency blankets are a single layer of polyester film covered in a later of vapor deposited aluminum. This is not very efficient because it is so thin reflecting about 70% of light and 90% radiant heat. If not attached flush, they can create hot spots and the blanket tears easily once punctured, but is a very cheap option.
