hydroponic system

Wick Hydroponic Systems

The wick system operates under very simple parameters, in that it’s passive, with no moving parts attached to it. A wick is used to draw nutrients from the reservoir and into the growth tray and it’s a fully automated procedure that takes little effort from you.

Water Culture Hydroponic Systems

Like I said in the introduction, the water culture was the first type of system invented in hydroponics. It stands on fairly straightforward principles: a reservoir filled with nutrient solution, atop of which the gardener places a floating platform that can hold several planters (or cups, or something similar). The roots of the plant that you “install” will be drowned in the nutrient solution, with the rest of the plant being held by the planters.

Drip and Ebb and Flow Hydroponic Systems

system/>Ebb and flow hydroponic systems can be found everywhere and together with their younger brother, the drip system, they make up the majority of hydroponic gardens in the World. Both types of systems work on basically the same principles: a growth tray is attached atop a nutrient container. Nutrients are flooded into the growth tray by a pump, they are absorbed by the plants and the excess solution that couldn’t be absorbed is drained down into the nutrient container, recycling it for future use.

Nutrient Film Technique Hydroponic Systems

Another popular hydroponic system, the NFT uses a constant flow of nutrients to wash out the plants’ roots, feeding them in the process. Because this system uses no growth media for the roots, it allows for better oxygenation and it has low maintenance costs in the long run. Just like the ebb and flow or drip systems, the nutrient film technique floods the growth tray (where the plants’ roots are dangling in) then drains the excess back to the reservoir. Like with the above mentioned hydroponic systems, this kind of nutrient recycling is a great way to save nutrients, but unfortunately it also creates pH instability in the reservoir, which leads to more complicated problems later on.

Aeroponic Systems

Although not hydroponic systems per se, aeroponics use some of the basic principles in water-based soilless plant growth, but use air vapors instead. Plants are usually suspended on top of a reservoir in aeroponic systems, with the container being tightly sealed. A mechanism creates vapors out of nutrient solution and sprays the result in the reservoir, engulfing the dangling plant roots. This helps them acquire nutrients faster but also allows for some great oxygenation capabilities, which cause your plant to grow heavily.

Many indoor gardeners employ the Ebb and Flow method (also known as the Flood and Drain method). With this hydroponic gardening system, a submersed pump floods the grow tray with a nutrient rich solution at regular intervals. A mechanism monitors the surrounding environment to help determine the amount of nutrients to provide to the plants for optimum growth. With this hydroponics grow system, gardeners can use a variety of different growing mediums. Gravel and Grow rocks are also helpful when placed in the bottom of the grow tray to help the plants get the nutrients provided by the solution. Or, for smaller plants, gardeners may choose to use individual pots that they can easily move around if needed. Beware of power outages, though. Since some equipment runs on electricity, a power outage can cause the roots to dry out quickly.

The water culture technique is an ideal way for providing nutrients to your hydroponics grow system. Using this raised gardening method, plants are placed on a Styrofoam sheet which is floating in water that is rich in nutrients. A pump then bubbles the nutrient-rich solution towards the roots so they get a great mixture of essential nutrients and oxygen. The ideal vegetables to grow in the water culture method are lettuce and other small plants that grow rapidly in water. Plants that do not grow well in water should be grown using one of the other hydroponic gardening systems. The water culture method is also popular for classrooms to teach young students about the growing process.

Perhaps the simplest method for a hydroponic gardening system, or raised gardening, is the Wick method. With this hydroponics gardening method, there are no expensive equipment to buy and no moving parts. The gardener simply places one end of the wick into a solution rich in nutrients and the other end of the wick is placed into the growing medium, where the plant roots are. The nutrient solution is then transferred into the growing medium. For diagrams and free plans about how to build this type of hydroponics grow system, visit simplyhydro .com. One disadvantage of this hydroponic gardening system though, is that it is not ideal for large plants, as they use up the solution and water faster than the wicks can supply the nutrients.

You can discover either hydroponic gardening systems or raised gardening methods that provide a wide array of benefits to passive or avid gardeners. With a hydroponic gardening system, you can be as involved or as uninvolved with the growth of your plants as you want to be. Gardeners have been able to find many hydroponic gardening system diagrams and plans in books and on the internet, including many free ones at "simplyhydro .com". Finding a hydroponic gardening system that suits your needs is not a difficult task.

Plants metabolise carbon dioxide and H2O to make required energy through the function of photosynthesis. Light is key because it supplies the energy required for this transition. The concentration of the light has been found to boost the measure of energy made. This will keep on going up until the plant reaches its saturation point for light, so you should consistently try to step-up the quantity of light your plants get. Plants grown in an out-of-door garden would commonly take in 8-12 hrs of sunshine per twenty-four hours based on the climate. You should seek to imitate this as well as imaginable to maximize photosynthesis. Make certain to distance plants out sufficiency to head off having them deflect the light from each other.

Insufficient lighting will hinder your plants and may pass on permanent developmental impairment even after lighting conditions are changed. The stalk will be thin and extended causing it to have trouble supporting the plant as it sprouts. A decreased number of leaves may spring up and the leaves that do grow will not flourish to their regular size. As the plants mature they will not be able to bloom or bear fruit and may even become yellow based on the duration of the lighting insufficiency.

Reduced carbon dioxide (CO2) measurements can also limit your plant's capacity to photosynthesize. Plants can synthesize much more carbon dioxide than is commonly seen in the standard atmosphere. You can enhance the quantity of carbon dioxide usable to your plants by using a carbon dioxide system in your indoor hydroponic lay out.

Effective exhaust fans will cool your plants and spread the air so a clean supply of carbon dioxide and O2 are usable at all moments. An oscillatory fan set on the equivalent timekeeper as your lighting should supply sufficiency ventilation for the majority of indoor gardens, but bigger layouts will plainly require a more involved fan rig.

Depending on the kind of hydroponic scheme you employ, H2O quantity may or may not be a problem. Whichever setup you select make certain to consistently keep decent H2O for your plants. H2O problems will cause persistent lack of yield even if it is counterbalanced rapidly.

H2O caliber on the other hand, can be a important issue for any hydroponic growing setup. Tap water in many sites includes minerals and salts, which can change the nutrient balance of your hydroponic solution. This is commonly called "hard water" and can frequently be counterbalanced by changing the mix of your nutrient solution. endeavor to keep the salt of your water beneath 325 parts per million (ppm) whenever you can.

Plants grow better between a certain spread of temperatures. Extreme temperatures may lead to smaller development and deficiency of fruit output. Of course, good growing temperatures can diverge from species to species, but warm-season veggies and many kinds of flowers grow better in between about 65° and 80° F. Other cooler-season vegetables such as cabbage ordinarily grow better in between 50° and 65° F.

When I began reviewing hydroponic components and starter's kits on the Internet and nearby gardening suppliers. I was amazed to discover that basically you can purchase from a simple hydroponic unit costs about $20 to greenhouse with full automation costs $20,000. The vast range of product and amount of information available is both pleasing and confusing. While you have a great range of products to choose from, it is not easy to make a choice.

Therefore, before you buy anything or start looking for a starter's kit, get a few good hydroponic gardening beginner's guides and take your time to read up on the subject. Then develop a rough idea of the size of the hydroponic unit your want and what you want to grow in it. Much of the beginner's kits won't make sense unless you understand the basics of hydroponics and your needs.

It is very important to have an idea what you want at the very beginning. For example, a person who spends $30 a simple hydroponic system may later find out that 7 days a week, 3 times a day, he/she must be available to pour nutrient over the aggregate. For the busy city dweller, this could be a hassle. In this case, an automated hydroponic system will be more suitable for him/her.

Just to let you have an idea of the common types of hydroponic systems Water Culture System, Ebb and Flow System, Nutrient Film Technique (NFT) System and The Drip System.

When you start planning for your very first hydroponic system, the followings are just some of the considerations:
- Where do you want to plant, outdoor or indoor?
- How much space do you have?
- How large a hydroponic unit you need?
- What the types of plants do you want to grow?
- How many plants will you grow?
- How much you can afford to spend?

Once you have decided on your hydroponic system, you can handle your purchase in one of two ways

1. If you enjoy working with your hands, making things, gain tremendous satisfaction from what you create, then you can build your own unit by following the steps provided in the guides, and just restrict your purchases to those things you cannot make or otherwise adapt from materials at hand such as pump.

2. If you will rather concentrate on the actual growing of hydroponic plants using a system that is proven, then you can buy an entire hydroponic unit including a container, an aggregate and for some degree of automation, a pumping device. Many kits also include an initial supply of nutrients.

Once again, if you are new and keen to try out hydroponic gardening, then read. Personally, I think if you do it for the first time, then it will be good to get some books, at least two to three books. Because different authors likely focus and provide more details on more than one hydroponic systems based on their own experiences. So reading a few guides allows you to have better understanding of various types of systems and helps you to identify the best system suitable your needs.

A good basic guide should provide a parts list, a tools list and step-by-step instruction, and advices to ensure that you are able to build a good hydroponic system. In fact, nowadays, there are also guides on the internet coming with video clips to better illustrate the building process.

Hydroponics is fun and simple to learn, hope you will enjoy.

Hydroponic Systems & Techniques The science of hydroponics has evolved since its inception with the development of two main systems – the water based hydroponic systems and aggregate based hydroponic systems. Water based hydroponic systems use water around the plant roots for delivery of nutrients. In aggregate based systems, plant roots are supported in some kind of inert material such as rockwool, pebbles etc. Both Water Culture Hydroponic Systems and Aggregate based Hydroponic Systems may use one of several different techniques of nutrient delivery to plant roots depending on requirements particular to the system.

Water Culture Systems Water culture systems use water for delivery of nutrients which can be delivered to plant roots in different ways. Several techniques can be used; some of the more common of these are -

Nutrient Film Technique In nutrient film technique a plastic trough or tube is used as the container through which a thin film of nutrient solution is made to flow continuously. Plants are grown out of holes on the top of the tube with their roots in the trough. The thin film of nutrient flows constantly past the roots. The trough is positioned to slope gently in order to maintain the circulation of the nutrient solution through the nutrient reservoir, to the plant roots and back. This is a popular technique with the home gardener and comes in many variations.

Aeroponics makes use of a nutrient mist delivered to the roots by a vaporizer or some other means. An A shaped frame constructed out of Styrofoam boards forms the support-base for plants. The plants are placed in holes on the inclined sides of the frame with the roots reaching out through the holes. The nutrient mist sprayed inside the A frame which then settles on the roots from where it is absorbed by the plant. Excess nutrient runs down the frame, is collected and recycled.

The aeration method was one of the first hydroponic techniques to be developed. In this method plants are suspended 1 inch above a nutrient solution collected in a container. An aquarium air pump is used to bubble oxygen through the nutrient solution. The plants are carried in a 2-inch deep mesh tray that fits inside the container when the lip of the tray is placed over the container’s edge. Gravel, clay pebbles or vermiculite filled in the tray serves to hold the plants and at the same time allow the roots to grow down into the nutrient solution.

Aggregate Systems Aggregate systems use inert materials such as rockwool, clay pebbles, gravel, etc. to support plant roots. The inert media serves to support the plant and also allows good oxygen penetration to the roots in addition to retaining a thin film of nutrients and water.

The flood and drain method is the most commonly used aggregate system. In this system a container is filled with aggregate and plants which is then flooded with a nutrient solution. The solution is then drained back into the nutrient reservoir by opening a valve at the bottom of the container. The roots should be submerged for not more than 20 -30 min. during each cycle.

Another widely used aggregate system is the trickle feed method. The nutrient solution is continuously pumped from a reservoir through a 1/2-inch irrigation tube. This tube branches into several 1/8-inch tubes that feed the solution to containers carrying the aggregate and plants. Solution that may be in excess gets collected at the base of each container and is then returned to the nutrient reservoir.

Hydroponic systems offer several advantages over conventional soil based systems of growing plants. They afford better control over plant growth eliminating weeds and soil borne diseases. Many indoor greenhouse also optimize plant nutrition helping grow better crops more economically.

One aspect of plant culture that is wise to keep in mind is to pay attention to the growing conditions a particular plant needs to survive and thrive. Poor choices for hydroponic-style gardening are succulents, because they will only thrive in dry conditions, and you are attempting to grow plants in the medium of water. Water-loving plants make a good choice for Hydroponic gardening, because the plants will be growing in water. Melons are a good example of a fruit that grows well in this circumstance. Watermelons and cantaloupe can both be grown successfully hydroponically because both are water loving plants and can thrive in this sort of growing medium.

Although not considered a fruit by some, nevertheless tomatoes meet the scientific criteria for classification as a fruit. Tomatoes grow wonderfully in a hydroponic environment as long as they have excellent lighting.

Other fruits that grow well hydroponically are berries. You can grow strawberries, blueberries, blackberries and raspberries very well in a hydroponics system.

Grapes are another favorite fruit that you can grow using this method as well. Both table grapes and wine grapes have been successfully grown using hydroponic methods.

Surprisingly, there are some trees that can be grown in a hydroponic manner. Banana trees are one, and dwarf citrus trees, such as lemons, are another. Imagine growing fruits that would normally require a tropical or very warm climate to produce fruit during an Alaskan or Scandinavian winter, through the appropriate use of a hydroponic plant system and the correct lighting and proper nutrition.

All plants will receive absolutely no nutrients from soil, since this system uses none, so the gardener must supply the plants with nutrients in the form of a nutrient solution. You water the plant with the nutrient, and the plant takes the food up through its roots. Typically the nutrients are dissolved in distilled water, because the water needs to be very pure. If you use your own water, you will likely want to have the water tested for elements that may already be present, so that you do not provide too much of any one nutrient.

Hydroponic-system gardening is an excellent way to increase fruit yields over conventional soil gardening, and it allows gardeners to grow fruits that would otherwise not be possible in their climate or soil.

1. The hydroponic system structure must be able to support the root system without soil.

2. You need to have an efficient method of supplying air, light, and nutrient to your plants.

When these two requirements are fully satisfied, you can then begin experimenting a more complicated and automatic system.

To meet the first requirement which can be quite easy with the help from good beginner’s guides. All you need is a simple hydroponic unit that consists of a waterproof container filled with a growing medium or aggregate for root support. You place seeds or young plants into the aggregate. Then you pour a nutrient solution over the aggregate to feed the plants, and that’s it, you have your own hydroponic garden!

Unfortunately, most of the times, when the hydroponic system is in operation, beginners encountered several problems. This is mainly because the second requirement is not well planned. No matters what kind of system you select, air, light and more importantly, nutrients are vital to your success. Therefore, while you are planning for a hydroponic system, it is always a good idea to get a few good hydroponic gardening guides and put a bit of extra efforts in studying about nutrients. You won't regret.

One of the important considerations for the second requirement is the type of nutrient you want to use. When selecting a nutrient to use, keep in mind that the nutrient must be designed specifically for hydroponic application. Using common fertilizer is not advisable as these products are designed for use as a supplement to soil gardens and may not contain sufficient essential elements to suit the hydroponic condition. Of course, there are also many commercially available hydroponic nutrients that make it easy to get started in hydroponic gardening for those prefer not to make their own nutrients. However, again, these commercially ready hydroponic nutrients are usually designed to satisfy the widest range of plants, lighting conditions and stages of growth.

Hydroponic nutrients come in all flavors, powers and liquids, single part, two part, three part or even more. Selecting the best one for the plants may not be easy for beginners. Majority of the experienced growers prefer a system that is simple to use, inexpensive to own and effective at growing a wide variety of crops to their fullest potential without additional supplements. In general, two part and three part nutrient formulas are always better than the single part or general purpose formulas because they allow you to custom blend your nutrient solution for each crop and stage of growth for better performance.

So, while you are working on your hydroponic nutrients, it is always good to learn to mix your own nutrients in different concentration and combinations to tailor for the specific growth requirements of your crops. Good hydroponic gardening guides usually recommend their own recipes of self-made nutrients that have been proven successfully numerous times by the experienced authors/growers. So beginners can always start with these recipes and slowly experiment them to get the best growth from your plants by adjusting the amount of ingredients.

Let me start by explaining a little about hydroponic gardens. To put it simply, hydroponics is the process of growing plants without soil. Instead of soil or compost, the roots of the orchids are placed in a mineral nutrient solution.

Hydroponic systems have become very popular in recent years, not just for orchids but all plants in general. There are many advantages associated with growing plants/crops in a hydroponic system. These advantages are beneficial especially to commercial farmers where their livelihood depends on the success of a crop yield.

The soilless nature of hydroponics means that soil borne diseases are no longer an issue. How many times have one of your orchids developed a disease which originated in the soil and infected many orchids before you realised? This will not happen in your hydroponic garden which means there is less need for pesticides.

Not only do you not have to purchase any soil, you will no longer need to perform possibly the worst part of orchid care – weeding. Due to its nature, hydroponics removes this mundane task from your schedule.

As you will be aware, over watering an orchid is a very common mistake. Your hydroponic system will allow you to set up the correct watering schedule. You will also prevent waste by not watering weeds.

You can set up a hydroponic system almost anywhere. This means that if you have very little space you will still be able to set up your own garden. It also means that your climate will have less of an influence so you could try orchids which would never grow in ‘your’ type of soil.

Do you ever have problems getting your enough light to your orchids? Well, with a hydroponic system more of your orchid is exposed to light. As more of the orchid is visible, especially the roots, it becomes easier to make a quick diagnosis of any problems which will prevent disease from spreading.

Due to advances in science we now know the nutrients which ideally suit the orchid. This means that our orchids get everything they need to grow in the right quantities. So if you set your hydroponic garden up correctly, all your care will result in you growing beautiful orchids.

Nigel owns OrchidCareExpert.com a website which contains lots of useful information if you wish to know more about orchid care.

One of the best reasons to consider growing plants in your apartment hydroponically is that this type of system is much easier to get set up than hauling heavy containers and soil up several flights, and the end result is fresh food for your family. To get started with a hydroponic garden in an apartment, you will need to know that there are two basic systems you can choose from: water based and media based. Medium is not soil, but instead could include composted bark, gravel, peat moss, perlite or vermiculite. Also, if you select an active system it will need electronic timers and pumps to make it function well, whereas a passive system doesn't rely on pumps and instead uses a wicking agent for the roots of the plants to access the nutrients.

Because the plants are grown in water, they receive no nutrients from the soil as they ordinarily would. Instead, in hydroponic plant gardening the gardener supplies the plants with nutrients by applying a nutrient solution to the roots via distilled water. The big three nutrients that plants need are nitrogen, phosphorus and potassium. There are other nutrients, called macronutrients and micronutrients, that the plants will need as well and will need to be added to the nutrient solution. Macronutrients are needed in greater amounts, and micronutrients in smaller amounts, but all are needed for plants to thrive.

One of the benefits to growing plants in a hydroponic manner is that they are less bothered from pests and diseases. Many plant pests live in the soil, so when you eliminate the soil you often get rid of the pest's habitat. Hydroponic plant propagation can also be accomplished without using a great deal of pesticides Another reason why this style of gardening is popular is it will produce more food than you could grow in the same amount of soil. You can grow the food in a spot where there is no soil at all, namely, your apartment. So have fun gardening and produce some great-tasting food with hydroponic plant gardening.
