Minimizing Unpleasant Odors in Your Hydroponics Systems

clipped from www.homehydroponics.info

If you are running home hydroponics systems, you probably have had to contend with unpleasant odors wafting from your grow room. While this may be less of a concern in professional hydroponics systems, it can sometimes be discouraging for your average home hydroponic grower to feel like they have to constantly mask the odors in their own house. While you can’t change the fact that many of the materials used in hydroponic growing have a potent smell, there are certain steps you can take to ensure your house does wind up smelling like a greenhouse.

Today, hydroponics is used in a variety of settings. Wherever soil is unavailable, hydroponic gardening seems to appear. Wildcatters on offshore oilrigs grow their own tomatoes. Cooks on nuclear submarines hydroponically grow vegetables to use in there crew’s meals. Right now, plants are growing on orbiting space stations without a single grain of soil.

This video is an outline of the equipment and steps neccessary to build your own hydroponic garden.

Hydroponic Gardening for beginners

The Benefits of Hydroponics

hydroponicsHydroponics 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.

When is it too early to love hydroponics?

Hydroponics is definitely the wave of the future. But it’s nice to get proof of this once in a while. The Hooked-on-Hydroponics Awards were just announced for kids who are involved with growing fruits, vegetables, or flowers hydroponically, in a classroom setting. Read all about it at the following url. (For the best hydroponic newsletter on the web, please go to http://www.advancednutrients.com/newsletter)

When children and
teens explore how to grow plants hydroponically (without
soil),
fruitful
questions
bloom,
and these
questions can lead to active investigations and problem
solving.
These studies may even lead to classroom business opportunities

Urban hydroponics greenhouses to be located in high-rise buildings

Our best minds look to a future of urban gardens that feature Controlled Environment Agriculture located in tall buildings which will eliminate the need to transport produce to market and provide much fresher fruits and vegetables (and flowers) to city folk than conventional field farming.

Cities may sprout vertical farms
Proposed high-rise greenhouses could help solve a looming food crisis, professor says.

The world is going to need vertical farms because conventional agriculture can’t handle what’s to come, Despommier says. By mid­­century, the world is expected to add another 3 billion people, pushing its population close to 10 billion. Feeding all those extra mouths will require finding an area of agricultural land larger than Brazil – without cutting rain forests needed to stabilize the world’s climate.

And indoor agriculture is more efficient. One indoor acre of strawberries can produce as much as 30 outdoor acres can. In general, indoor acreage is four to six times more productive, in part because of the year-round growing season. “Outdoors, you might get one crop [per year]; indoors, you might get four or five crops per year,” Despommier says.

There are Many Hydroponic Systems to Choose From!

example of a hydroponic systemThere are many Hydroponic Systems that a grower can choose from and they are as follows:

1. Water Culture or Aquaculture. This is the method of hydroponics that is the simplest to set up on a small scale. In this system the plant roots are totally immersed in a nutrient solution. The major disadvantages of this system are the large amount of water required per plant and the need to aerate the solution continuously. The system must provide means to support the plant above the solution, aerate the solution, and prevent light from reaching the solution (to prevent the growth of algae).

2. Aggregate Culture. Growing plants using aggregates like sand or gravel is often preferred to the water culture method since the aggregate helps support the roots. The aggregate is held in the same type of tank used for a water culture system. The nutrient solution is held in a separate tank and pumped into the aggregate tank to moisten the roots as needed. After the aggregate has been flooded, it is drained to provide aeration. Enough water and nutrients cling to the aggregate and roots to supply the plant until the next flooding.

3. Aeroponics. In an aeroponic system, the roots of the plant grow in a closed container. A misting system bathes the roots in a film of nutrient solution and keeps them near 100% relative humidity to prevent drying. The container may be of almost any design as long as it is moisture proof and dark.

4. Continuous Flow Systems. The nutrient solution is held in a large tank and pumped or allowed to flow by gravity to the growing pipes. The continuously flowing nutrient solution bathes the roots and then returns to the holding tank. The solution aerates itself as it flows back into the tank.

5. The Ebb and Flow (or Flood and Drain) System. Many growers consider this the Rolls Royce of hydroponic systems. It usually involves the use of multiple modules or double buckets—the inside bucket or basket contains the grow medium, such as baked clay pebbles, while the outside bucket is flooded periodically by a pump on a timer for a set period of time, let’s say 15 minutes, then the solution is drained back into the reservoir. Aeration takes place automatically each time the solution is drained, since the resulting vacuum sucks air into the buckets.

Take your pick!

Name change for this blog

I discovered that Avocado99 was widely used (without my permission.) Some guy is posting videos on YouTube under that name, while somebody else is running a MySpace page. I decided to retire the name and rename this blog.

Oh, I’ll still sign my pieces “Avocado99” but I’ll run under the new title, in order to reestablish my rights of ownership and exclusivity.

Brock Greenbud, the real Avocado99
