Automated Hydroponics (Hydroponics (Methods (Bottle Hydroponics (Also…

- - - - Also known as the Kratky method, this simple hydroponics system is small and versatile. It can be grown in any location (with little tweaks) and can grow a large range of crops. It does not require electronics, construction, or power tools. Although it is simple, it does not produce yields as large as other, more complex methods.
    - - A subtype of deep water culture hydroponics, this method entails a floating raft that holds the plants, keeping the roots completely submerged in the nutrient solution. Ranging in size, possible in any location, and requiring only a little construction, this system works best with shorter crops that require little oxygen for their roots. Although crops that require oxygen in their roots can be grown with the system, a air pump is often necessary to aerate the solution the plants are suspended in.
    - - This flexible system uses capillary action, the way that water is able to defy gravity with surface tension and adhesion, to keep plants hydrated. Similar to some traditional gardens, this system is less suitable for the indoors and tends to require construction, but does not require electronics. Crops that can be grown must be tolerant of wet conditions and grow best if they are smaller due to the often limited size of the garden.
    - - A circulating hydroponic system, this method keeps plants watered with a stream of shallow nutrient solution in growing channels. Although size can be a challenge, as this method tends to take up more space, it is lightweight, water-efficient, and easy to customize. This method requires a little more planning, due to factors such as flow rate and design, and grows plants with roots that won't block the flow of the nutrient solution best.
    - - A recirculating hydroponics method, this system utilizes irrigation lines to deliver the nutrient solution to the plants. Here, the solution is dripped onto the plants as they grow and is drained out and recirculated. Although it requires some assembly and is a larger hydroponics system, this method is better suited for larger crops such as cucumber and tomato plants. It is best suited for greenhouses and the outdoors, is water-efficient, and requires electrical work.
    - - This method is popular in aquaponics, or the combination of aquaculture (raising aquatic animals) and hydroponics. The bed that holds the plants provides a lot of surface area for beneficial bacteria and filters out fish waste. Although it's substrates are limited and it can be difficult to clean, this method is great for customizing and growing a wide variety of plants.
    - - Also known as an "ebb and flow" system, this popular technique ranges in both size and variety of crops. Suitable for any location, the method work by pumping a nutrient solution into grow trays that are then drained of excess. The many variations of this technique affect its location, crops, and size, but all require electrical work.
    - - One of the newer hydroponic growing techniques, this futuristic-looking method has the possibility for large yields and quick growth. Within aeroponics, there are two main categories: high pressure and low pressure. High pressure uses misters that are inserted into pipes that water plants that are suspended above the pipes, while low pressure systems use perforated disks and/or splashing to get the nutrient solution to the plants roots. Much like the other systems, this system is versatile and suited for any location, but this method is the most risky for new growers. Since the roots are not always in water, it is likely that the roots will become dried out to a point of permanent damage.
    - - Popular with growers that have limited space, this often-decorative method works best with leafy greens, herbs, and strawberries. There are a few different ways to do this method, such as aeroponic towers, drip towers, flood and drain grow racks, rotating/ferris wheels, NFT A-frames, and rain gutter systems. Although these systems are often very aesthetically pleasing, they do not do much to improve crop yield, increase growth speed, or help keep the plants alive without care.
- - - - The Arduino Uno is an open-source microcontroller that is based on the ATmega328. A microcontroller board is a computer designed to to run one specific program that does not change often once it is finished. This works well with my project because there will likely be one program written for the system that will "tell" it how to do the different functions necessary for my system and when to do them.

      - Relay Module:
  - - - Also known as the Arduino Integrated Development Environment, this open-source system makes it easy to upload programs to Arduino boards. It is written in Java, and is based on Processing, another software sketchbook. To clarify, this is where code for the Arduino is written and uploaded.
      - How it works: After writing the program and pressing upload, the program is translated into the C programming language, and then translated again by a avr-gcc compiler which makes the commands readable by the actual microcontroller itself so that it can perform the tasks it has been given.
