Hydroponics simply means growing plants without soil. Food for the plants, called hydroponic nutrient, hydroponics nutrients, fertilizer for soilless gardening, or plant food, etc. (may be organic), are dissolved in water and fed directly to the roots automatically.

Plants form smaller roots and grow in inert grow media (i.e. gravel, sand, water or even air). If you haven't seen it for yourself, you will be amazed.

I love vegetable gardening, especially with help from the science of hydroponics. Vegetables are prolific, seasonal, tasty, colorful, and nutrition degree. Now you too can enjoy effortless hydroponic vegetable gardening.

Hydroponic Tomatoes from some, might seem like a new invention, but all that is hydroponically grown tomato is a tomato that is grown with water, nutrients, light and air.Now, my main experience with hydroponic tomatoes was done using my Aerogarden system is a hydroponic system in that it does not use soil so that the mess that you have to worry about is slim to none except If you're like my husband and really sloppy with the watering can! Here's what I found and my adventure when I was growing hydroponic tomatoes in my using my Aerogarden.

Outdoor activities - outdoor wood burning fireplace in the patio

The first thing I found when I grow hydroponic tomatoes is that for some reason, they pushed a lot faster than I've ever seen a regular tomato growing.However, with the hydroponic tomatoes I think it's because of the constant supply of water, nutrients and light. Who is that all plants need to grow, but with the hydroponic system you are able to control exactly how much they get each of these items. Thus, the rapid germination of my tomato plants hydroponically me really excited because my stock of winter tomatoes ran down the last of my garden fresh tomatoes harvested began to go wrong.

So after waiting a few weeks my hydroponic tomatoes were high enough that I had to move my lights do not burn and I also had to support them, otherwise they fall.Now, with hydroponic tomato plants that support them is a little different from your other tomatoes, normally intended that you will not be able to use a tomato cage because you do not dirty cage address.So with hydroponic tomatoes you'll have to use some type of rope or wire to the plastic support with.

Whatever you do end up using your hydroponic tomatoes will be considerably different from what you are outdoors and you want to ensure that the material will not cut into your tomato plants.

Buying a hydroponic system or building a system

This is the most asked question relating to hydroponics. Should I buy one or build one? This author recommends a little of both. If you have an engineer's mind and dream of building your own hydroponic system, buy one first! Getting an inexpensive system will allow you to get your feet wet and give you a better understanding of how hydroponics works. The hands on experience is worth the cost of the system and chances are, you will be able to reuse the parts in that system when you set out to build your own.

If you would rather get right into building your own, do your research. Get all the information you can and don't rely on just one source. This is a constantly changing industry and there are many books still on the shelves that are already outdated. Building your own system can be very rewarding or extremely frustrating. It's mostly trial and error so, be patient.

Hydroponic gardening is the wave of the future. It is currently being studied in classrooms around the country, local horticultural societies and in government funded research at major universities and NASA. It is also becoming a popular hobby. Hydroponics is fun, exciting and easy to get involved in.

 

Hydroponic systems

Hydroponic systems are characterized as active or passive. An active hydroponic system actively moves the nutrient solution, usually using a pump. Passive hydroponic systems rely on the capillary action of the growing medium or a wick. The nutrient solution is absorbed by the medium or the wick and passed along to the roots. Passive systems are usually too wet and do not supply enough oxygen to the root system for optimum growth rates.

Hydroponic systems can also be characterized as recovery or non-recovery. Recovery systems or recirculating systems reuse the nutrient solution. Non-recovery means just what it says. The nutrient solution is applied to the growing medium and not recovered.

The Wick System

The wick system is a passive non-recovery type hydroponic system. It uses no pumps and has no moving parts. The nutrients are stored in the reservoir and moved into the root system by capillary action often using a candle or lantern wick. In simpler terms, the nutrient solution travels up the wick and into the root system of the plant. Wick systems often uses sand or perlite, vermiculite mix and a growing medium. The wick system is easy and inexpensive to set-up and maintain. Although, it tends to keep the growing medium to wet, which doesn't allow for the optimum amount of oxygen in the root system. The wick system is not the most effective way to garden hydroponically.

The Ebb and Flow System

The Ebb and Flow hydroponic system is an active recovery type system. The Ebb and Flow uses a submersible pump in the reservoir and the plants are in the upper tray. They work on a simple flood and drain theory. The reservoir holds the nutrient solution and the pump. When the pump turns on, the nutrient solution is pumped up to the upper tray and delivered to the root system of the plants. The pump should remain on for about 20 to 30 minutes, which is called a flood cycle. Once the water has reached a set level, an overflow pipe or fitting allows the nutrient solution to drain back into the reservoir. The pump remains on for the entire flood cycle. After the flood cycle the nutrient solution slowly drains back down into the reservoir through the pump.

During the flood cycle oxygen poor air is pushed out of the root system by the upward moving nutrient solution. As the nutrient solution drains back into the reservoir, oxygen rich air is pulled into the growing medium. This allows the roots ample oxygen to maximize their nutrient intake. Rockwool and grow rocks are most commonly used growing mediums in Ebb and Flow type systems. The Ebb and Flow is low maintenance, yet highly effective type of hydroponic gardening.

Nutrient Film Technique

The Nutrient Film Technique or NFT system is an active recovery type hydroponic system. Again, using submersible pumps and reusing nutrient solutions. The NFT uses a reservoir with a submersible pump that pumps the nutrient solution into a grow-tube where the roots suspended. The grow-tube is at a slight downward angle so the nutrient solution runs over the roots and back into the reservoir. The nutrient solution flows over the roots up to 24 hours per day.

Oxygen is needed in the grow-tube so capillary matting or air stones must be used. The plants are held up by a support collar or a grow-basket and no growing medium is used. The NFT system is very effective. Although, many novice hydroponic growers find it difficult to fine tune. It can also be very unforgiving, with no growing medium to hold any moisture, any long period of interruption in the nutrient flow can cause the roots to dry out and the plants to suffer and possibly die.

Continuous Drip

The Continuous Drip system is an active recovery or non-recovery type system. This system uses a submersible pump in a reservoir with supply lines going to each plant. With drip emitter for each plant the gardener can adjust the amount of solution per plant. A drip tray under each row of plants, sending the solution back to the reservoir, can easily make this system an active recovery type. In the early days of hydroponics, the extra solution was leached out into the ground. Continuous Drip systems are often used with Rockwool. Although, any growing medium can be used with this system, thanks to the adjustment feature on each individual drip emitter.

The benefits of hydroponic gardening

Hydroponics is proved to have several advantages over soil gardening. The growth rate on a hydroponic plant is 30-50 percent faster than a soil plant, grown under the same conditions. The yield of the plant is also greater. Scientists believe that there are several reasons for the drastic differences between hydroponic and soil plants. The extra oxygen in the hydroponic growing mediums helps to stimulate root growth. Plants with ample oxygen in the root system also absorb nutrients faster. The nutrients in a hydroponic system are mixed with the water and sent directly to the root system. The plant does not have to search in the soil for the nutrients that it requires. Those nutrients are being delivered to the plant several times per day. The hydroponic plant requires very little energy to find and break down food. The plant then uses this saved energy to grow faster and to produce more fruit. Hydroponic plants also have fewer problems with bug infestations, funguses and disease. In general, plants grown hydroponically are healthier and happier plants.

Hydroponic gardening also offers several benefits to our environment. Hydroponic gardening uses considerably less water than soil gardening, because of the constant reuse the nutrient solutions. Due to lack of necessity, fewer pesticides are used on hydroponic crops. Since hydroponic gardening systems use no topsoil, topsoil erosion isn't even an issue. Although, if agricultural trends continue to erode topsoil and waste water, hydroponics may soon be our only solution.

What does hydroponic gardening mean?

Hydroponics is a popular and environmentally friendly alternative to traditional gardening; and even if you have no yard, you can take advantage of its unique benefits in order to provide healthy, fresh produce for your family. Hydroponic gardening is perfect for city dwellers, commercial plant growers, schools, and farmers alike. Build yourself a hydroponic system, or buy one of many commercially available models, and you will be well on your way to enjoying a plentiful harvest.
Hydroponics is a centuries-old method of growing plants without the use of soil. The nutrients plants normally dervie from soil are delivered directly to the plants' roots. In a hydroponic garden, plants are suspended in growing trays. Without soil, the roots of the plant need not expand in an effort to seek out nutrients; therefore more plants can be grown in a smaller space. Plants no longer compete for root space or nutrients and grow faster and produce more fruit or flowers. Hydroponic systems often employ a growth medium such as Vermiculite, Rockwool, gravel or Perlite to physically support plants.
There are two basic types of hydroponic gardening: passive and active. In a passive garden, plants are suspended from a grow tray and their roots rest in a reservoir of water and nutrients. Alternatively, the grow tray may rest above the reservoir and the water or nutrients be passed to the plants via a wick. In an active garden, a water or nutrient solution is delivered from a reservoir to the plants at timed intervals via a water pump, drip line or spray line. In many active hydroponic gardens, the water or nutrient solution is recovered and returned to the reservoir for recirculation. In both active and passive systems, it is necessary to use an air pump to oxygenate the water or nutrient solution.
