Difference in hydroponic gardening

Posted on by blogger

When growing hydroponics, there are a vast variety of growing mediums that may be used. The mediums include materials, including perlite, vermiculite, coconut fiber, gravel, sand, or any number of other materials. Even air may be used as a hydroponic growing medium. The hydroponic growing medium is an inert substance that does not supply any nutrition to the plants.

All of the nutrition comes from the nutrient solution, typically combining water and fertilizer. Hydroponic fertilizer and fertilizer intended for use in soil (regularfertilizer) contain the three main nutrients. These nutrients are nitrogen, Phosphorus, and potassium. The main difference between hydroponic fertilizer and dirt fertilizer is that hydroponic gardening fertilizers contain the proper amounts of all of the essential micro-nutrients that regular fertilizers do not include. The plants are expected to find these elements in the soil.

Problems may arise for the plants if any or all of the micro-nutrients are not present in the soil or have been depleted by successive or excessive plantings. Hydroponic gardening fertilizers are usually in a more pure form than are regular fertilizers so they are more stable and water-soluble.

Organic fertilizers are typically very different than either the hydroponic fertilizers or the dirt fertilizers in how the deliver nutrients to the plants. The organic fertilizers rely on the action of bacteria and microbes to help break down the material into its basic elements so the plant can easily use it. Hydroponic and regular fertilizers then supply the plants with these elements.

Another difference between hydroponic and regular gardening is that growing hydroponics can be extremely complicated. Hydroponics are controlled with computers and sensors which help control everything from watering cycles to nutrient strength, and the amount of light the plants receive. However, hydroponics can also be very simple. The average home hydroponic system usually consists of a few basic parts, including a growing tray, a reservoir, a timer controlled submersible pump to water the plants, and an air pump to oxygenate the nutrient solution. Light is, of course, also required to help the hydroponic garden to grow.

There are also micro-nutrients that are required for healthy plant growth. These micro-nutrients include calcium, sulfur, magnesium, boron, cobalt, iron, copper, manganese, zinc, and molybdenum. These nutrients are the essential elements that plants need in very small amounts. Plants are likely to become sick without these trace elements and will develop all sorts of problems depending on which nutrient is missing.

The lack of micro-nutrients in food crops can mean a lack of nutrients in the food. This will result in the food not being as healthy as it could be and potentially lead people to develop health problems due to the lack of these essential elements. Any hydroponic gardener needs to use a good quality hydroponic fertilizer when they are growing plants using hydroponics.

Gardeners should always monitor their system too much rather than too little to avoid any problems. The ability to quickly and easily test and control pH in hydroponics is a major advantage over regular gardening, where testing and adjusting the pH is much more complicated and time consuming.

How To Fail At Csa Market Gardening

Posted on by blogger

CSA market gardening is a great way to connect farmers and consumers. The farmer receives a good income and guaranteed cashflow, and the consumer gets a steady supply of fresh, local food. But your CSA can fail if you don’t avoid the following mistakes.

CSA market gardening mistake 1: Marketing. Community Supported Agriculture programs typically experience high turnover of customers, especially in the early years. You may lose as many as 40% of your customers each year. This means you need to be continuously marketing to find new customers to replace the losses, and even more if you expect to grow.

Marketing your garden doesn’t have to be difficult or expensive; the first thing to invest in is some good business cards. Cards are a cheap way to promote your market garden. You can print both sides of the card, perhaps using the back of the card as a coupon for new customers.

Mail-out flyers are also an effective marketing tool. Flyers let you target a particular geographic area, and a 1-page 2-sided flyer gives you lots of room to get your message across.

You should also consider creating a website for your market garden; having a web presence is expected of businesses these days. And a well-designed, keyword-focused, content-driven website is your marketing magic weapon, bringing in customers even while you sleep.

CSA market gardening mistake 2: Not growing enough produce. When customers join your CSA, they often pay you in advance for the season. You have to make sure you deliver great value for that payment. This starts with planning.

Since you know how many customers you have, you can plan your garden to make sure you have ample produce for everyone. For example, if you have 50 customers who each want one head of lettuce each week, you need to be able to harvest at least 50 heads. However, not all lettuce seeds germinate. And not all plants successfully grow to produce a harvestable crop. You can lose plants to insects, or disease, or bad weather. So to make sure you will have sufficient produce available, you need to build in a safety factor; that is, plant more than you think you will need. So to get 50 harvestable head of lettuce, you might start by planting 75 seeds; this will give you some allowance for losses.

And you have to take all reasonable means to protect your crop from the perils mentioned above. You need protection against insects, disease, flooding, predatory animals, drought, and storms. It does you no good to grow beautiful vegetables if you lose them before harvest.

CSA market gardening mistake 3: Not growing enough variety. Successful CSA’s grow lots of vegetables, and a large variety of vegetables. There are some good reasons for this: first, your customers will appreciate receiving something different in their delivery boxes each week. The more types of vegetables you grow, the more people you will appeal to.

The second reason to grow a large variety is for security of production. To give an extreme example, if you grew only two vegetables, and you lose one, your garden has lost 50%. On the other hand, if you grow 20 different vegetables and you lose one, you garden is still at 95%.

And finally, you need to grow a large variety of crops to stretch out your season. Different vegetables, and even different types of the same vegetable, mature at different times. The more you grow, the longer your potential season.

CSA market gardening can bring a great benefit to both farmers and consumers, if you avoid these mistakes.

Why Hydroponic Gardening Is Becoming More Popular

Posted on by blogger

Hydroponic gardening has spiked in popularity recently mainly because the quality and productivity of hydroponically grown plants has been unmistakable. These plants grow faster and healthier than their soil-grown counterparts. This is due to the fact that they are grown in an environment where there is a virtual limitless supply of nutrients and water at their disposal.

These hydroponically grown plants, because they are not grown in soil, do not need to fight off diseases and pests which are natural in soil. Pesticides can be decreased or even eliminated.

And because the nutrients and water are delivered in just the right proportion directly to the plant’s roots, they are better equipped to grow – faster, healthier, larger!

Hydroponically grown plants have the following benefits:

– They will provide high levels of nutrition

– They will be better tasting

– They will be rich in color.

In hydroponic gardening you will find that the crop’s water and nutritional needs are less complicated and sometimes more effective. Just a few simple measurements and it will be evident what adjustments need to be made to the nutritional balance in the water. All the guesswork is eliminated!

Although nutrient solutions are available from local hydroponic suppliers and contain the correct proportions of essential minerals, gardeners may also make their own nutrient rich solutions. This may sometimes require quite a bit of extra work however.

When it comes to the growing medium that will provide plants their nutrition, different materials have been successfully used. Materials such as sand, porous rock, gravel, pumice, perlite, and vermiculite have all proven to be good choices. Fired clay particles can also be used. These all are capable of providing a way of getting the nutrient rich water into the plant’s root system.

Also, there are various types of containers and pumping arrangements for delivering nutrient solutions to the garden and draining it back to the storage tanks for reuse.

If you’re just starting out in hydroponic gardening you may be wondering which types of plants are most suitable for hydroponic gardens. The answer to this is tomatoes, peppers, lettuce, and cucumbers. There are some types of tomatoes that will continue to produce year round.

Some plants can be started from seeds and seedlings. In this case use commercially available rock wool plugs submerged in the media. These make excellent incubators for germination and seedling growth.

And since hydroponic gardens are self-contained, they can be located just about anywhere space permits. It is not unusual to find these by windows, on rooftops, or in closets.

Kitchen Food Dehydrators – A History Steeped In Piracy

Posted on by blogger

How do you feed a world that is becoming increasingly hungry? This is not a new question and one that according to the Food Preservation Team from the Department of Nutritional Science at the University of Missouri has been plaguing food engineers for decades if not centuries. According to their research achieving this grand goal cheaply and efficiently on a global scale is the challenge. Food preservation through dehydration may hold the key to feeding masses of hungry people. While the future of food dehydration may be stellar, its history over the last several centuries may hold some surprises.

Food drying or dehydrating is believed to be one of the oldest methods of food preservation throughout human history. It allowed hunter-gatherer societies to successfully travel, explore and hunt for different food sources. The development of agriculture was the single, major factor that made it possible for mankind to settle in permanent communities and transition from hunter-gatherer nomadic tribes. How to save or preserve these foods for a later date is a whole separate study. Research has showed that the first ancient stable, settled, civilization arose in Mesopotamia and Egypt in the Middle East. The uncovering of dried fruits, grains and dried, salt preserved fish and meat are traced back to over seven thousand years to these first ancient civilizations. Farming eliminated the constant need to search for food and allowed populations to grow through the production of a more stable food source. There are neither volumes of recorded history nor any one source of collected material on food dehydration. However very recent Middle Eastern archeological digs have un-earthed food samples which research determined to have been dried foods originating in ancient Jericho over 4000 years ago. In addition, Old Testament Biblical scholars have been able to isolate bits and pieces of scripture which mention the preservation methods of sun-drying and smoking foods over a hot fire as a means of feeding their people.

For centuries, much of the European diet depended on dried cod, known as salt cod or bacalhau (with salt) or stockfish (without). It formed the main protein source for the slaves on the West Indian plantations and was major economic force within the trade routes of the day. The next mention of food drying doesnt emerge again until around 1630. At about this time in history a band of French mavericks began appearing up and down the Yucatan peninsula and Caribbean islands. They were known as the buccaneers. The term buccaneer was actually derived from the Caribbean Arawak word buccan which is referencing a wooden frame for smoking meat. The meat of preference at the time was the plentiful, slow moving manatee or sea cow. From this became derived in French the word boucane and hence the name boucanier for French hunters who used their wooden frames to smoke meat from feral cattle and pigs on Hispaniola (now Haiti and the Dominican Republic). History of course tells us the rest of the story about the buccaneers. English settlers occupying Jamaica began to spread the name buccaneers with the meaning of ruthless pirates when in reality it was referring to their ability to dry meat. The name became universally adopted later in 1684 when the first English translation of Alexandre Exquemelins book The Buccaneers of America was published.

Along with an amazingly colorful history which includes ancient roots and ruthless piracy, food dehydration is even today on the forefront of cutting edge food engineering and preservation. Todays food dehydrator is a surprisingly simple capsule of modern technology and historical know how. Todays typical kitchen food dehydrator has electronically generated air flow along with micro-processor governed temperature control. In place of the wood frame on the beach is an amazingly compact, ergonomically designed piece of history that fits snuggly on a kitchen counter. With multiple level trays, even air flow and constant temperature control a person can dehydrate a large volume of fresh fruits, veggies and meats literally over night. The simplicity, efficiency and very low cost of the modern food dehydrator is once again taking center stage in the complex world of food preservation and engineering. Developing nations and countries that have endured natural disasters are re-discovering the practicalities of food dehydration to feed their hungry masses. The buccaneers of yester-year had no idea how their simple practice of meat drying on the beach would become a modern means of feeding a hungry world.

Build Your Own Eco-friendly Water Soaker Garden Irrigation System – Conserve Water

Posted on by blogger

You looked at installing a underground sprinkler system on your property. And then stopped short when you realized the thousands of dollars it would cost! How could plastic pipe and sprinkler heads cost so much? Here is a lasting inexpensive water irrigation system that is near maintenance free and will have your neighbors wondering why they never see you watering your garden and plants. You can claim yours to be an environmentally friendly garden soaker system (or water drip system), using the minimum amount of water to sustain your plants and shrubs.Get the water as close to the plant roots as possible. Using less water is important to our global environment.Communities now encourage water soaker systems instead of sprinkler systems. Water applied near the ground will mostly be absorbed into the earth where it is needed by the plant and grass roots. Water sprayed above the plants and grass lands on the leaves and flowers before dripping to the ground. This longer exposure to the air will cause much of the sprayed or sprinkled water to evaporate into the hot summer air.More than ever now communities control the watering of lawns and gardens during the summer months. Sometimes you are restricted to garden watering only – not lawns. An automatic water timer system combined with a soaker hose system makes plenty of sense in reducing the amount of water dispensed to water your garden plants and shrubs. So how can I make an effective soaker system for my garden for under $500?With some off-the-shelf components, you can have a simple but elegant soaker system that with be automatic and near maintenance free. With a simple water timer system, Y-connectors, faucet multipliers, some 1 1/2″ abs pipe, quality 1/2″ garden hose and your choice of soaker hoses or irrigation hoses for potted or hanging plants, border gardens, row gardens or (dare I say) even lawn sprinklers. You now have the elements for a simple soaker irrigation system for your garden. This do-it-yourself automatic water irrigation system will ensure you water plants at the best time every day; specifically, early morning and late afternoon. As an added home security feature, when you are away from home your garden will sustain its beauty and make it look like someone is at home.Here is the material list required for your automatic garden soaker system. (Note: there is a complete Picasa image gallery of all the required components of this inexpensive soaker system at http://picasaweb.google.com/carl.chesal/GardenIrrigationSystem ):1) Select your water timer I selected Orbit from Home Depot. Make sure it has a battery timer so power outages won’t alter your scheduled watering times. It should allow for at least 3 watering zones.2) Select your main faucet multiplier (or Valve splitter) that will attach to your outside water faucet and can accommodate the 3-4 water zones plus a spare to allow for regular garden hose watering. You can secure these special faucet multipliers from garden centers or at Lee Valley Tools. 3) Enough 1 1/2″ ABS pipe (and glue) and 22.5 degree elbows to run underground (6″ – 10″ depth). Use the 22.5 degree elbows only to allow for easy insertion of the garden hose into the ABS pipe. You can cut further costs by burying the garden hoses directly underground. The ABS piping does provide added protection from accidental puncture from aerators, pitch forks and other garden tools. This ABS pipe can also serve double duty to run low voltage wire or speaker wire to the remote areas of your garden.4) Enough quality garden hoses to run through the ABS pipe and connect to the soaker hoses in all your garden beds.5) Soaker hoses for all your garden beds.6) Enough Faucet multipliers (Valve splitters) to extend each watering zone with soaker hose as required.Creating your automatic garden soaker system involves more of a landscaping effort than anything else. Here are 3 steps to completing your eco-friendly automatic garden soaker system (Note: refer to the Picasa image gallery for details of component assembly):1) Bury the ABS pipe feeding the garden hose through it as you connect and glue the pipe sections. Bury the pipe 6″-10″ under your lawn or sidewalk. Have both ends extend out of the ground using the 22.5 degrees elbows so that the stiff hose can still be easily pulled through the pipe.2) Connect the soaker hoses to the ends of the garden hoses and weave the soaker hoses through your garden under plants and around shrubs. Follow the installation instructions of the soaker hose manufacturer.3) Install the water timer and water zone valves on the faucet multiplier. Connect the hoses for each zone. Follow the installation instructions of the water timer manufacturer. Do not set the water time for each zone more than 20 minutes each. Set two water times early morning (around 6 am) and late afternoon (around 7 pm).Maintenance of your Irrigation System and Preparation for Freezing Winter Temperatures:1) Disconnect the [zone] hoses at the main faucet where the Water Timer is located. 2) Using a Shop Wet Vac, suck the excess water from each zone hose. Use electrical tape to secure the vacuum pipe against the end of the hose. Turn on the wet vac and let it run for 10-15 minutes. Empty the water extracted before repeating this for each hose at the main faucet. You will extract enough water from the hoses so as not to incur any winter damage to your hoses from freezing water.3) Tape a plastic bag over the ends of each of the [zone] hoses. This will prevent little critters from getting in the hoses and clogging them when you reconnect the system in the spring.4) Remove the water timer and faucet multiplier. Store them in a warm place where they will not freeze.5) Note: you DO NOT need to disconnect and remove the soaker hoses. They should last 4-6 years before you need to replace them. Check the soaker hoses each spring for holes. You can patch these holes with high-friction Silicone tape. You may also leave outdoors all-year-round any valve splitters that were used to increase the soaker hoses in a particular water zone.You now have an inexpensive water soaker system that won’t break the bank. You have saved thousands of dollars and can boast of being a friend to our environment. You clearly are doing your part for water conservation and the ecology. Nice going!
