About This Class


If you are interested in growing your own food or homestead projects but don't know where to begin, this class is for you! :)

The Kratky method is a form of passive hydroponics. This means that no pumps or electricity are needed during the growth cycle. You just need a water reservoir, cups, seedlings, growing solutions and you're good to go! :) This is a great benefit to a new grower who wants to keep things as simple as possible. 


Happy planting! :)

1. Introduction: Growing at a slower pace, world population is expected to reach 9.7 billion in 2015. Could pick it nearly 11 billion after 50 years. In this scenario, how can we feed the world? Countries around the world, especially developing countries like mine with receives ness of hunger and food scarcity is more severe. I was starting to values counterstrategies to meet the growing demand. Home gardening or a time-tested strategies that are widely adopted and practiced in various circumstances may local communities with limited resources and institutional support. This is part of agriculture and food production systems. In many developing countries. In the face of a global food crisis, globbing your own food is a simple solution on to numerous health, environmental, and economic problems. Whether you're growing a lattice, single tomato, or just any herbs is beneficial to your health as well as the environment. Hi everyone, I'm Christine and let me help you and how you can go your own healthy fluid at the comfort of your home. Growing fruits and vegetables seems overwhelming to most people, but it's actually quite simpler than it sounds. All you need is a few square feet in your home or water source and a little money, effort, patients and time. Let me introduce you to hydroponics Democrat key method. 2. What is Hydroponics?: Let us discuss first what is hydroponics score? Hydroponics is a method of growing plants, but instead of using soil, it depends on water-based nutrient solution. The ADM may seem like an oval head, but has actually been around for thousands of years and help to enable population growth. As the availability of arable land decreases. Also, over the last decade, people's interest in how their food is produced has greatly increased. More consumers want safe food that has been produced with a sustainable mindful growing practices and is free from pesticide residues. As a result, Merkel tumors are choosing to grow their own food and many exploring hydroponics. Hydroponics comes from the Asian declamation of hydro, meaning water and panics, meaning labor. The water is doing the work here and enabling the fast growth of the plants. Hydroponics works in a variety of scenarios, from grabbing a small collection of herbs in a kitchen. Although we opt in numerous plants in a large-scale commercial operation, people with limited or an altar space such as urban residents, apartment enters who can't have an ordering garden, find hydroponic growing very useful. Of the best plants that grow in hydroponic system include herbs, lettuce in greens, tomatoes, peppers, and strawberries. But as a rule, avoid plants that grow tall like coin have deep taproots like potatoes, or grow in a binding insurer. Hydroponic plants are exposed to light to allow for the process of photosynthesis. And plant roots are exposed to air, allowing the roots to capture oxygen that they need to grow. Nutrients mixed into water included phosphorus, nitrogen, and calcium. 3. History of Hydroponics: If wiki Study back to the 600 BC, plants will be in grown in soil or school. Sure. If any of you, if it was not identified directly as hydroponics, the patient hanging guidance of baby learn and floating guidance of the Aztecs in Mexico where hydroponic in each war. In 1856, professor Julius von Sachs publishes the first formula, auto nutrient solution that can be dissolved in water to grow plants. This standard formula, we just a few minor tweaks is used for the next eight years. In 19 thirties, Dr. William Frederick Greek it professor in a plant nutritionist at the University of California, growths tomato vines 25th high in his backyard using only water and nutrients. And he coined the name hydroponics. And during World War II in the 1940s, shipping a fresh vegetables to obviously it's outposts was not practical. And a coral iodine is not a place to grow them. Curiosity in hydroponics was revived and government sponsored experiments began. The United States and British armies establish height of hydroponic units at military bases on several islands in the Pacific to provide fresh produce the troops during wartime. In 1965, nutrient film technique or the NFT, a hydroponic technique developed by Alice. The method involves a very shallow stream of other film of water recirculating past the bear fruits of plants in a channel. And also the required nutrients are dissolved in the water. In the 1900's, hydroponics went mainstream. This new world introduced living within, if it really stick right, you hydroponics gardens off tomorrow. Also at high Times, Magazine began to detain simple hydroponic system, introducing thousands to whole new way to grow buds. Do these smart hydroponics, advances in hydroponics have grown tremendously in the last century. We now fully understand that healthy plants require water, sunlight, carbon dioxide, and nutrients to drive. 4. Types of Hydroponics: Types of hydroponic system. First is the electronic system. This is the most high-tech and usually more expensive, but they're also one of the most effective systems. In this system, the plants and roots are suspended in here. That reservoir we add oxygen air pump past Misters which spray a fine spray over the plant roots. Some growers will use so nonstop fine mist well, others will missed on a cycle, the cycle of MS. Teeny shorter than the flawed and rain model with only a few minutes between each each cycle. This allows the roots to continuously have nutrients without oversaturation or submersion. It also naturally allows the roots to have greater exposure to oxygen, which is critical for growth and development. Second is the drip systems. This is usually found in commercial settings as opposed to residential, because they're better implemented in a larger scale. This system anchors each plant in a small part filled with a soilless planting mid-June and uses a system of small troops to flip the nutrient solution into the roots of each plant. The Randolph is collected in a pan or tree below the parts and then circulated back to the tubes using a pump. You it to monitor their nutrient balance in your solution on and check the lines and shapes for clients. Nice setup can be used to grow larger plants like tomatoes, melons, and bumpkins. Is the nutrient film technique or the NMT system. This system uses gravity to supply routes with nutrients and water in water pump center, center anytime or pushes water through the channel. This delivers a thin film of nutrients and water to the plants where the roots are not completely submerged. At the end of the channel, the solution drops back into the main reservoir to be used in the system. The deep water culture or the BWC. This consists of others or water filled with water and nutrient solution. The plants are suspended over the reservoir using the net part and growing media. The roots themselves are submerged in the reservoir so they have a constant supply of water and nutrients. The NMT system, plant roots need oxygen or they can drown. So we need to use here an air pump with the air stone to pump bubbles in. There is a war to continuously oxygenate the water and deliver the necessary oxygen to the roots. Fifth, an ebb and flow system, also called the flood and green flattery plants with nutrients on a cycle. This is a less common practice because it's not as flexible to your plants needs. Some growers like this system though, because it doesn't continuously exposed to plant roots student nutrient solution. You feel a tree with a grouping museum to house the plants. At time pump will fly that way with nutrient solution. And as I click Schedule, the cycle of flooding depends on the type of dance, water testing, the Earth temperature, the growth cycle in more. After flooding the tree, gravity drains the solution, I'm back into the reservoir to be re-used. An air pump should oxygenate the water in there is a war. As it waits for the next flat cycle. This system can work well if you have strong monitoring processes to understand your plant's growth intake of nutrients. And last, the crack key method. This is the ECS system to maintain for most growers, we just need the tub filled with nutrients, solution, and suspense plants in pots overeat so that the roots are partially submerged. This partial wetting allows the roots to take up nutrients while also exposing them to oxygen. As another simple passive system, the Gracchi method is one of the best hydroponic systems for those who are new to working with water. It is easy to set up and get going. Now I'm gonna teach you how to set up the Gracchi hydroponics method. 5. The Kratky Method: The Gracchi method is a passive hydroponic system that is simple and low maintenance, making it perfect for anyone who wants to garden, but doesn't have a lot of time or experience or materials like bumps or any irrigation systems. Because it's pretty much just planning, setting water. And it works for a quick history. The Gracchi hydroponic method was developed by Dr. Burnett caret key, a professor of botany to the University of Hawaii. He first began experimenting with crappy hydroponics in the light in the late 1990s to grow plants without using soil. The method is named after him and has since become popular among homebrew words for its simplicity and low maintenance requirements. 6. Kratky Method: How does it work?: Believing the gulp of air above the water, our plants grow healthy roots and get all the oxygen they need. As the plant drinks more water and nutrients, the water level goes down in the roots, grow down with it. By measuring the correct amounts of water from the start. No refilling or circulation is necessary. Simple yet effective strategy is what makes quite key the only real passive unplug system. 7. Kratky Method: Advantages: Now that you know what the crack key method is and how it works, let's discuss the benefits of using this method. The best thing about the crappy system is just how we see it is to set up no need for tubes, filters, dimers, or any mechanical system. Another benefit is the lower of its initial cost. I bet you'll have the material of aquatic system in your home right now. Also, little effort is needed. As we all know, gardening can be a time-consuming task. Tronic failure, or a mist watering. They could mean the end of your little plant. When word is always scary in a way, the fruits of labor seemed new arena board. The quickie method is great as it doesn't need to be checked off in. It is simple as it gets. Just make sure you get the nutrient solution right and you're good to go. In this method, plants grow fast and have great yields. Believe it or not, studies have shown that fields are as good as ones from the other method. You are in sacrificing any delicious veggies for the simplicity of this method. And last, you can also make some extra cash. Once you have a setup GUI, you can expand and sell your crops to local restaurants and formal markets. Because anything homegrown, especially organic, will usefully fetch a premium. 8. Kratky Method: Disadvantages: Well, the credit card system is great. It doesn't come without its downsides, but for the disadvantages, it is not that great for larger blanks. While the system is great due to how low maintenance it is, bigger plants need much bigger containers. Second, the lack of scalability. The grid DC stem is great for at home and small-scale weeds. But net for large-scale operations can be great for meeting the needs of your kitchen and impressing friends and family. But trying to meet any kind of large-scale production goals with this system is just impractical. Potential for pests. Because this is a passive system. It opens itself up to potential pests. If exposed the standing water, it can attract various insects, especially mosquitoes. This can be an issue for people with an outer set up. In order to help avoid these, you should look to avoid exposing water anymore than necessary. But these are some of the disadvantages of using the secret key method. 9. Kratky Method: Best plants to grow: But what are the best plants to grow with a crappy method? The key works best within leafy greens. These include lettuce, peanuts, kill, Bok Choy, and some herbs. But in this class we're gonna focus on growing lettuce. It's true that some vegetables way easier to grow then address. If you want to start off with something that will build your confidence in hydroponic. Let's start with the letter score then. If you haven't tasted any fresh homework, let us, I think you're missing out. It's far superior in these and vitamin content, the distort both alternative. It is also one of the most popular crops for any hydroponic growing method because all of its varieties grow well using the caret key method. Now I'm going to fool you step-by-step on how we go. Let us in a small backyard using the crap key method. 10. Kratky Method: Materials Needed: Materials needed for germination. We need, let us see it's sterilized coco peat seedling tray, net parts or cup. For cranky setup, we just need some kind of war with a leader is really simple plastic container that will hold the water and nutrient mix will do. We just need to lead because let us will seep in a hole in it. It also blocks the light from the nucleus solution and it keeps pests away from the roots and slows the evaporation of the liquid. We also need net cups. These are plastic cops for holding your suit, your siblings, they need to have holes in the bottom so that the roots of the plants can go through. Of course, the hydronium, hydroponic nutrient. Instead of pulling the three fund from the soil, hydroponic plants get it from the water. We will need to combine the liquid or a solid nutrient mixes store water to feed our lattice. And last, we need a pH measurement tools. Beach Police are very important role in determining the solubility of the nucleons. Most veggie screw in a slightly acidic condition. 11. Kratky Method: Lettuce Seed Germination: The first step in growing lettuce is CD-ROM mini fun, Zoom in Asia and is a very important factor for growing any plant. One of the key factors of CG rumination, it's the right growing myth. You, for me, cocoa beat is the best growing museum for a lattice. It is extracted from coconut husk and it goes under some processes to become a medium suitable for growing plants. Aside from that, it is eco-friendly or all natural materials. We can repeatedly use these inner garden. Why we need the sterilised? Basically sterilizing kills any viruses or bacteria that developed and good effect. New seedlings grows. This way we will effectively eliminate pathogens, Excel laundry as well as harmful fungi. The moisture and why I'm that increased Germany's on also provide the perfect breeding ground for harmful microorganisms that live in it. There are two common ways to sterilize liquids, software or bid, which is biochemical or a bucket. We can use various chemical products like hydrogen peroxide or ammonium salts. But if you don't want to use chemical products and one more eco-friendly which I prefer. We can choose to buy here. First, we just need the boot, the cocoa beans in boiling water for like 15 to 30 minutes. Let it cool down in brain is in squeezed to remove the water. Once ready, get resilient tree infinity with cocoa. Mix small hole in each cell of the cylinder tree. But let us see it in those holes and governance lightly with a bit of coco peat. If your bid is already dry ice, bridge just enough water to my stem. But don't make it wet because too much water will not let the roots grow and expand to their full potential. If you're solving more than just one variety of lead to stone, forget to label them. Let us see its usability. Seven to ten days to germinate or less untamed if it will only be good evolve these depend on the quality of the seed. During the germination process, makes sure that your plants are getting the right amount of sunlight and the soil is constant, consistently moist. 12. Kratky Method: Lettuce Hardening Off: Once this is how Germany, they will turn into small seedlings, will treat for a tiny leaves and now ready for hardening. What is hardening? It is simple process of gradually exposing tender plants to sunlight, nutrient water and even temperatures. Personally, a lake adding the nutrient water when they are just about out of the seedling stage. So the seedlings can gradually addressed in the nutrient water and it can support its growth. Because generally you will notice that the growth, It's starting to slow down because they are lacking with the nutrients to continue this east, when we will start adding the solution, I only use 50% solution to the water, meaning half of the normal mixture. Us instructed in your nutrient solution. 13. Kratky Method: Growing Stage: After a few of these to begin, I'll transfer the baby lettuce to the reservoir and start the crack key method. So of course, we need to prepare the reservoir. First, drill or caught the lead to eating large enough to please and hold the cup. Second, fill the reservoir with water. Distilled. Water is fine as long as it is not contaminated. Preparing of nutrient water, the amount must be carefully calculated to suit the size of the container or level of the water. After you have added are nutrients. Check the pH level of loose solution with a pH meter released by 0.5 to 6.5. The nutrient solution is right. If not, adjust the pH level of the water. Remember, pH adjusters Scan be the jewel so it is important to use it cautiously at all times. Always wear safety gear will help in handling need including gloves and eye protection. Leads the cops with the baby lettuce and there is a war. Keep parts of the roots Humphrey in the ear and the other parts sound into the nutrient solution. The next question is, can you feel you're cranky reservoir? Definitely, yes. If you notice the plant's roots are in touching the water, there is no hormone and refilling your quaternions of war. However, the whole point of the Socratic method is that it is passive, meaning you don't need to do anything to the system once you start it. If you measure the correct amount of liquid the first time, you will never need to refill it. The roots will grow down at about the same rate that the water level goes down. 14. Kratky Method: Waiting Time!: And now you're on your way to grow in your letters hydroponic. From here, the catechist system will self-sustained. Simply monitor for any drastic changes. You are now one step closer to conquering the gardening world. Now you just have to wait.
