Agriculture / Do You Want To Know How Bug Zappers Work? by Selvage1: 3:28pm On Apr 08, 2020 |
Having quite some fun outside in the evening, aren’t you? While you are enjoying your time, several harmful bugs are feasting on your food, or you are their food. A bug zapper helps you to keep those nasty bugs from sucking on your blood or eating your food. “ZAP” that’s what we hear when a bug zapper is in action. Ever wonder how bug zappers work? Let’s find out. What is a bug zapper? [img]https:///1269/1012965006_4c060f5911_b.jpg[/img] A bug zapper is a device that attracts insects with light and kills them. Usually, insects that are allured by light fall victim to it. The bug zapper is formally known as an electric discharge insect control system, electrocute trap, or electric insect killer. It usually attracts the insects with its light source, where they come face to face with an electrical grid. Touching two high voltage wires between them makes them electrocuted. The name bug zapper comes from the onomatopoeic zap sound produced by it when an insect is killed. History of bug zappers: First bug zappers were introduced in 1911 by Popular Magazines that had a piece showing a fly trap. The flytrap had all the elements of a modern bug zapper, which includes the electric light and the grid. Two unnamed Denver men implemented it, but it was too expensive for practical use. In 1932, the first bug zapper was patented by William M. Frost, according to the US Patent and Trademark. Dr. William Brodbeck Herms, a professor at the University of California, paved the way for modern bug zappers by introducing the electric insect killer in 1934. Parts of a bug zapper: [img]https:///1269/1054937440_336f1896c4_b.jpg[/img] Bug zappers are quite simple, consisting of several parts. These parts include: Housing: The exterior casing of the bug zapper is called the housing. It is usually made with plastic or any such metal which is electrically grounded. The bug zapper is given the shape of a lantern, cylinder or rectangular cube. It may also have a grid design to prevent children and animals from being electrocuted by touching the inside. Light bulb: Usually, mercury, neon, or ultraviolet rays are used to make the light source. Since such types of fluorescent lamps are most likely to attract insects. Wire grids: Wire grids are usually two in number. It is the part of the bug zapper that is electrified to kill the insects that surround the light bulb. Transformers: The device that electrifies the wire meshes is the transformer. The voltage of this device goes from 120V to 2000V. The wire meshes are supplied with an increased voltage of 2000V by the transformer. There are tiny gaps between the wire meshes about the size of a typical insect, which allows them to enter easily. These small gaps are about 2mm(0.079 in). The light being ultraviolet allures it inside. It is because many insects see better in ultraviolet rays than in visible light and are more attracted to it. Flowers that allure insects during pollination reveal patterns only in ultraviolet rays. How do bug zappers work? Despite going through various improvements, the bug zapper is still the same as it was since 1934. Its safety and bug luring capacity are still the same with just a few ups or downs. An ultraviolet ray emitting from the light bulb attracts the insect towards the electrified wire-mesh grid. This is where the bug is electrocuted as soon as it touches the wires. A high voltage power supply consists of a transformerless voltage multiplier circuit. The circuit consists of diodes and capacitors. The tiny gaps between the wire are just the right size to fit in. The bug itself completes the circuit along with the transformer allowing the voltage to cross between the space and vaporize the bug. The highest voltage carried by it is 2000V. When the circuit is closed, a “zap” sound is heard from the zapper. Some facts about bug zappers: A bug zapper kills more than 10,000 insects in a single evening. However, it does not discriminate between the types of insects. It kills any insect that is lured by its ultraviolet rays owing to its outstanding luring strategy. Now, the controversy comes whether the bug zapper works or not. Obviously, it does. If you spend a night beside a bug zapper, you will know. However, it kills beneficial insects than harmful ones. A study published from the researchers of the University of Delaware in 1996 shows that, after collecting and identifying kills from six bug zappers from different sites, they found some astonishing results. Out of 14000 kills from the bug zapper, only 31 were mosquitoes and biting gnats. That is, it is killing beneficial insects like aquatic bugs more. This is causing a heavy toll on the nearby ecosystems to a great extent. It is because the harmful insects like the mosquitoes etc. are not attracted to UV light. They are more attracted to the carbon dioxide in your breath and water vapor in your sweat. However, now a day, we can see bug zappers that emit carbon dioxide and water vapor, which is a plus point. A bug zapper may not be the most effective way to kill harmful insects, but it paved the way for a better and modern approach to prevent them. Many alternative and better options are arising in this sector. Some are more non-toxic to humans and other animals. But our ecosystem doesn’t consist of humans and animals only, and there are many beneficial organisms as well. We have to make sure our repellents for mosquitoes do not kill them off. It will lead to many catastrophes. We must make sure to install the bug zappers with chemicals that only kill mosquitoes, not other insects.We need to the exact information of how bug zappers work properly. During this time, bug zappers have been installed with Octenol, carbon dioxide, etc. chemicals that allure mosquitoes and biting gnats only. Bug zappers with light sources other than UV rays are also being used. Not only this, other references to repel insects are becoming very popular. Yet the research is still going on to improve the bug zapper as time goes by. |
Agriculture / What Is Grow Room? by Selvage1: 9:16pm On Apr 02, 2020 |
There are 4 different types of potential grow room uses when growing a flowering plant such as medical marijuana. The first would be a small rectangular grow room, used for cloning machines. This can be used to contain your cloning activities separate from the rest of your plants (however you can always put your cloner with your other vegging plants if you prefer). You would just want to make sure you have enough room to hang lights over your cloner and of course have some type of minimal ventilation. The next type of the most commonly used grow tent would be your mother tent. This can be a variety of sizes depending on how big your mother plant is and how many clones you need to take. You would just again want to make sure that it is big enough to allow some growth and still have room to hang your lights. This is another case where you can just have the mom with your vegging plants. You then have your vegetation grow tent. This tent would be used to grow your newly rooted clones up into full bud yielding plants. A good rule of thumb is to use about 25% of the space that you will be flowering in. You may want to use a bit more if you opt out of using the tents above and just housing your mother plant and clones all in the same grow room. The final and most important room is your flowering room. While your plants are flowering it is very important to maintain optimal conditions in order to maximize yield and quality. This room should offer enough room to have osculating fans, your lighting system, and preferably plenty of room to ensure all major plant leaves are exposed to direct light. Or, you can always just use one big tent and do everything in one cycle rather than keeping a continuous grow. Why Use a Grow Tent You may be deciding whether or not to even use a grow tent. Grow Tents have been used for years to conceal grow operations and to maintain the security of the growers using them. With medical marijuana being legalized in states around the country, one might think that concealing your grow isn’t quite as important anymore, especially with a medical marijuana license. However; most people still want to remain anonymous to their neighbors and of course the police, making a grow tent the perfect solution. Using a grow tent, you can grow small amounts of medical marijuana for personal use without anyone having to know about it. Here are some other good reasons to own and use a grow tent: #Saves time and energy compared to building your own grow room #Increased light efficiency with reflective walls #Ability to control the environment and increase yields #Easy set up and take down, takes up minimal space when deconstructed #Ability to clone, grow, and bloom plants all in one area #Light proof for those nosey neighbors or if you still want to use the rest of the room without it being lit up #Already include inlets and outlets for cables, lights, irrigation accessories, and ventilation chambers
