![]() ![]() They do everything, but they do everything to an average level. Their jack of all trades approach is also part of the reason some growers avoid them. If you opt for an adjustable model, then light coverage can be altered as your plants develop to keep everything running smoothly. When you compare cost versus light coverage, wing reflectors stand out as the winner in this respect. This angled bounce not only helps prevent hot spots but offers a fairly even spread of light intensity. The wing reflects light in much the same way as the other types of reflectors do however, the angled design means the light rays will hit multiple points and bounce back in various directions. ![]() Their diversity is also the reason for their widespread popularity. They offer a balanced, often adjustable, middle ground for light coverage and light intensity. Wing reflectors would sit somewhere in the middle of both umbrella and hood reflectors. Umbrella reflectors also take up a lot of room so may not be viable for the majority of recreational or novice growers. Even if you shell out for high-quality reflective material on your umbrella, placing the lights too close to cannabis plants may burn the leaves, damaging them. The risk with lowering umbrella reflectors too far is that bulbs still generate a lot of heat. Light is dispersed over a wider area, but unless you decrease the distance between the top of your crop and the lights, light rays won’t penetrate much past the canopy roof. ![]() The increased light coverage comes at the expense of light intensity. For this reason, you would need less of them to cover the same area however, their most significant benefit is also their largest downfall. UMBRELLA REFLECTORSĪs the name suggests, umbrella reflectors offer a much larger footprint of light than the previously mentioned hood reflectors. With that in mind, you will need to think carefully about positioning to get the best bang for your buck. They are considered to be so versatile because they come in a variety of shapes and sizes however, the typically square shape of the reflector hoods gives a rather narrow reflective pattern, especially when compared to other types of light reflectors. They can be tailored to the space available, and depending on how much light you want to reflect they can create concentrated areas for a select few plants or cast a wider beam of light, typically suitable for commercial operations. Shallow and wide or tall and narrow, there is a good chance a hood reflector will be more than suitable for the majority of growing environments. The market has opened up tremendously, and as such, it is common for features to span differing models. Instead, we will list the most popular, categorized by how they are designed. It would be impossible to list every single type of light reflector variation there is. If the energy from light is lost to heat, rather than being reflected, all you will do is increase the temperature of your growing environment unnecessarily. ![]() Remember, we are trying to improve efficiency, so reflecting as many light rays as possible without any loss is our key objective. How reflective a surface is depends on how much of that energy is lost as heat. During the reflection, the surface it meets will absorb some of the light's energy, dispersing it in the form of heat. In this case, that surface will hopefully be a light reflector. Light will always travel in a straight line until it meets a surface it can bounce off of. The “best” option will depend entirely on your existing equipment and intended use, as well as your budget and the space you have available. There isn't necessary any one definitive light reflector that is the best. The complication comes from a vast array of light reflector designs, differing material and (in some cases) overinflated manufacturer proclamations. The result? You get better yields without wasting any of your already optimized lighting setups. Light reflectors divert that wasted light back down to your plants, increasing light coverage and intensity. The beams that upwards, well, that's a lot of wasted energy and money. Some will undoubtedly reach your plants and fulfill their intended purpose. Shining a light above your cannabis crop, regardless of how strong it is, is going to send beams of light in every direction. Shining a light is going to send beams of light in every direction including upwards. When growing indoors you will need one or more lamps above your cannabis plants. ![]()
