What is ideal PH in all hydroponics applications?

What is ideal PH in all hydroponics applications?

The two maximum necessary components in water and nutrient control are pH and conductivity, and a excellent figuring out and command of these variables is very important for successful hydroponic gardening.

pH is the measure of acidity or alkalinity of an aqueous resolution. If an answer is acidic then it has a pH in the vary of zero to six.9. If a solution is alkaline then it has a pH in the range of 7.1 to 14. Pure water or deionised water is neutral at pH 7.zero. The ultimate pH for most hydroponic gardening packages is between 5.8 and 6.2, except for for Rockwool cultivation, which likes a somewhat lower pH of about 5.5.


pH is the measure of acidity or alkalinity of an aqueous solution. The term pH refers back to the doable hydrogen/hydroxyl ion content of an answer. Solutions ionise into positive and adverse ions. If a solution has more hydrogen (certain) ions than hydroxyl (negative) ions then it is acidic and has a pH in the range of zero to 6.nine. Alternatively, if an answer has more hydroxyl (detrimental) ions than hydrogen (positive) ions then it’s alkaline with a pH in the range of 7.1 to 14. Pure water and deionised water has a steadiness of hydrogen (H+) and hydroxyl (OH-) ions, and is subsequently pH impartial (pH 7).

Why is pH important?

If the pH of an answer isn’t within the right kind vary the plant won’t have the ability to soak up one of the crucial very important elements required for right kind plant expansion. All plants have a specific pH vary, which is able to produce wholesome expansion, and this stage will vary from plant to plant, but maximum vegetation favor a slightly acidic growing surroundings (five.eight to six.2), despite the fact that maximum vegetation can continue to exist in an atmosphere with pH values between 5.zero and seven.0.

Growth Technology what’s pH how to regulate pHPlants grown in acidic environments can experience a number of symptoms, including aluminium (Al), hydrogen (H), and/or manganese (Mn) toxicity, in addition to nutrient deficiencies of calcium (Ca) and magnesium (Mg).

Conversely, in alkaline environments molybdenum (Mo) and macronutrients (except for phosphorus) availability will increase, however phosphorus (P), iron (Fe), manganese (Mn), zinc (Zn), copper (Cu) and cobalt (Co) levels are reduced, and would possibly adversely affect plant enlargement.

From the chart you’ll be able to see that each and every element can become more and no more to be had to the crops as pH adjustments. If the pH of your answer is out of the desired vary, one or more of the essential components will change into unavailable to the plant, causing nutrient deficiencies, which can result in sluggish expansion rates, and poor yields.

How to measure your pH?

There are a couple of ways to test the pH of your nutrient resolution, equivalent to paper check strips, liquid pH test kits, and virtual pH meters. The paper take a look at strips are impregnated with pH sensitive dyes, which change color when dipped into the nutrient resolution. The paper strip is then in comparison towards a colour chart to determine the pH of the answer being checked. The liquid pH kits paintings by adding a couple of drops of pH delicate dye into a small quantity of the nutrient solution after which the colour of the ensuing liquid is when put next towards a colour chart.

The maximum high-tech means of checking the pH is with a digital meter. All you need to do is dip the meter/electrode into the nutrient resolution for a few moments and the pH value is proven on an LCD show. The pH meters are fast and really correct when correctly calibrated. These meters need to be cared for correctly or they will no longer function. The glass bulb electrode needs to be stored clean, and some are required to be saved wet always. pH meters also need to be checked and calibrated incessantly to insure accuracy.
Adjusting your pH level

Passive Hydroponics

Passive hydroponic programs encompass growing in boxes or pots filled with a medium, corresponding to Soil, Coco, Perlite, Vermiculite, Rockwool Cubes, or hand-watering Rockwool Slabs.
Usually for this type of cultivation we’d suggest that the grower makes up one huge container of nutrient at a time. A 200 litre plastic drum is an ideal container. Once that is made as much as the correct ‘strength’ (conductivity), the pH will also be checked and altered to the best level of five.8-6.2. A careful observe will have to be product of the exact quantity of pH UP or pH DOWN that is added right now. In long term, this quantity will also be added as a regimen when making up solutions, and pH should remain lovely consistent from batch to batch, although spot checks are beneficial from time to time. Ideally you can use a meter, for example, BlueLab pH pen. The nutrient answer in the tank should remain solid and can be implemented to vegetation as needed.


Hard water is characterised through prime ranges of bicarbonates and it makes itself identified through depositing lime scale in kettles and by way of lowering the lathering ability of cleaning soap. Hard water will in most cases have a prime pH however not essentially. What will distinguish exhausting water is that it’s going to take a lot more acid to reduce the pH than with an an identical sample of softer water. This is for the reason that bicarbonates must be neutralized and this makes use of up rather numerous acid. The obtrusive downside for the grower is that he will be including reasonably huge amounts of acid frequently. If he’s using phosphoric acid this may lead to a build up of phosphate in the nutrient tank over time. High levels of phosphate within the resolution can inhibit the uptake of alternative components, zinc for instance, and cause basic nutrient imbalance.

Fortunately, properly formulated ‘Hard Water’ nutrient answers, akin to Ionic HW are designed to address this drawback. Conversely it’s essential to use a reverse osmosis gadget to filter your water, and then use the ‘regular’ cushy water nutrients.

Health and Safety:

pH keep an eye on chemical compounds are highly toxic and competitive liquids. Please practice these simple tips for safety and peace of mind.
ALWAYS retailer these fabrics in a safe place, preferably in a locked cupboard. Always stay them out of reach of children.
ALWAYS put on rubber gloves and protective goggles when dealing with any aggressive chemical substances.
ALWAYS dilute pH control answers sooner than use.

Hydroponic technique may help enhance vegetables, fruits production

The country can increase greens and end result manufacturing by way of 20 occasions through adopting fashionable agricultural technique ‘hydroponic’. This was once mentioned through agricultural mavens at the inauguration of hydroponic greenhouse, arranged by way of the Water Management Research Centre, University of Agriculture Faisalabad (UAF) right here Friday. UAF Vice-Chancellor Dr Muhammad Ashraf inaugurated the hydroponic.

Karachi University produces cherry tomatoes on mass scale

International Centre for Chemical and Biological Sciences (ICCBS), Karachi University (KU), has effectively produced overseas variety of tomatoes known as cherry tomatoes in its green houses at the huge scale. This is for the primary time in the history of Pakistan that any institution is generating all these tomatoes via using cutting-edge plant generation. The cherry tomatoes have been cultivated since closing two years, whilst this time the cherry tomatoes have been produced on the huge scale as examine to the final yr. Director ICCBS, Dr Muhammad Iqbal Chaudhary, revealed the truth whilst talking to the media on Tuesday.

[woo_product_slider id=”64262″]

According to Dr Chaudhary, seeds of cherry tomatoes had been bought from Canada and germinated on the biotechnology wing.

Dr Chaudhary

For preliminary adaptation the plant has been grown in green properties the place environmental stipulations have been comparatively controlled and it was once a fully insects-free surroundings. After first cultivation from seeds, disease-free and healthy plants were propagated on a mass scale using plant tissue culture techniques and chopping techniques.

The newly propagated crops have been allowed to develop to endure fruits in such a machine that they utilise the utmost gentle, humidity and vitamins He mentioned that the tomatoes could be picked when they are shiny and frivolously colored, except for when it comes to streaked heirloom tomatoes. A handful of crops will produce large volume of the small tomatoes, especially when they in reality get going in the sizzling summer season months, he added.

In cooler climates, cherry tomatoes do very best in a greenhouse, particularly if temperature is stored beneath 64 degrees Fahrenheit (18 degrees Celsius). The mass scale propagation the use of above-mentioned techniques is in a successful growth and shortly will be offered for advertising as a brand new number of tomato fruit with superb options and its crops for local farmers for cultivation in mass scale. In near long term novel feature options will be evolved using Genetic engineering, Dr Chaudhary concluded.

Produce or Perish! Choice is Yours

Produce or Perish!  Water crisis: Pakistan running dry by 2025, says study

Elections, Terrorism, celebrity controversies, media, movies, football and cricket wins are what rule Pakistan’s headlines but beneath all the commotion the country is battling a severe problem – a massive water crisis in future, no water no food no life.

Water shortage is one of the main thread to Pakistan agriculture in future, our water resource decline day by day and still we fail to develop new water reservoir while food demands increased day by day because the population of the country constantly increased. The second thread to our agriculture is the expansion of urban area that shrinks the cultivated area of the country and lasts but not the least thread is soil fertility problems like water logging, salinity, erosion etc decrease cultivation area.

In the future, we need more food to feed our population but we have less water and less fertile soil available for cultivation. We have two options

  1. Import vegetables from other countries for our daily use
  2. Produce vegetables for our daily use

Import vegetables is an easy way for us, during past few years we have the example of importing from India. Importing is a good solution only for a limited time because when we totally depend on other countries for our daily vegetable requirement we have no option to spend money on importing oil, medicines, engineering etc. mean we will spend only for our survival. The second option is produced our own veggies using less amount of water and land, this is a hard job need sincere and constant working. Sorry to say, now we are as a nation not like to work hard or think about the future even we do not agree to think about the future. 

Hydroponics cultivation is the production of vegetables and herbs using water in the soilless medium. Hydroponics farming save 40 to 70 percent water as compare to soil cultivation, water saving depends on hydroponics system used for cultivation. This the only way to produce vegetables accordingly our daily requirements using less amount of water and soil even produced in deserts or barren lands or on the roof of buildings. 

In the history of Pakistan first hydroponics farm in Pakistan was established by Tahir Rana in Faisalabad, he is a nuclear physicist who gave up a job in Canada to set up a vegetable farm. He earns a good profit two years but fails to run farm longterm. The question is why he stops working while earning the premium profit. The second farm is developed in Islamabad managed by Arid Agriculture University and the third successful farm is running in Abbottabad named Abbottabad Hydroponics. Some other small hydroponics farms working in Punjab, KPK, and Sindh.

Lt Cdr (retd) CV Prakash CEO of The Institute of Simplified Hydroponics, Bangalore India he has presented in his presentaion (March 2010) that “Has government support in many developed countries. India is yet to wake up to this reality. Even neighbor Pakistan has adopted Hydroponics cultivation with major government support.” ( Download Presentation: www.petbharoproject.co.in/downloads/Commercial-Hydroponics-%20Is-It-Viable.ppt). India government and peoples wakeup and start working on hydroponics but we sleep after starting working on hydroponics.

Screenshot of Presentation

If we think this is our big achievement, sorry to say this is nothing: our neighbor country start working after Pakistan but now we are moving like a turtle but they are working like a rocket. The question is simple: We are pioneer in hydroponics technology in south Asia but why now India is far advance in hydroponics and we are practically nothing? It’s better to ask this question to yourself, your researchers, your research institutes, your universities, your media and your government?

Hydroponic growing leads to tastier vegetables

Growing vegetables hydroponically leads to a more expensive, but tastier veggie, cumberlink.com reports.

Hydroponic growing leads to tastier vegetablesTomatoes are the king crop in hydroponics because of the demand for them in early spring and late fall when field tomatoes aren’t available. The challenge is to sell them at $2.99 per pound when field tomatoes are going for 99 cents, says Mark Toigo, 42, who has run hydroponic greenhouses for the last 15 years, among other duties, at the family-owned Toigo Orchards in Southampton Township, Cumberland County. Hydroponic grower Barb Rose, 52, co-owner of Beck-n-Rose of North Middleton Township, agrees with Toigo. She also developed a niche market in the last three years — a few chefs at “better restaurants who care what tomatoes look and taste like,” Rose says. She counts among her customers Fetter Brookside Market south of Carlisle, Mountain Lakes west of Carlisle, Oak Grove Farms of Mechanicsburg and the Butcher Shop in Chambersburg. For next season, all Beck-n-Rose produce is committed to current customers, says Rose, a former marketing manager for a start-up software company that sold last year for $40 million. “You do need to be a manager and a marketer” to be profitable, Toigo says, raising his voice above the half-dozen four-foot-wide fans that ventilate his 90- by 130-foot greenhouse off South Mountain Estates Road. He steps over piles of vines on the concrete greenhouse floor, the result of cropping the tops off tomato plants that have the last of the crop ripening on the vines. He will plant new tomato vines again in January for harvest beginning in April. Although growers would like to produce tomatoes through the winter, year-round tomato production isn’t feasible this far north. They say it doesn’t have the flavor of food grown in soil,” says Brubeck, who sells mostly to restaurants and to some grocery stores in Cumberland, Dauphin and Lebanon counties.

Detailshydroponic tomatoes Indian family makes a breakthrough in hydroponics

Indian family makes a breakthrough in hydroponics Indian family makes a breakthrough in hydroponicsAn Indian hobbyist has created a purely organic nutrient mixture for growing plants in water. Although it is still an evolving science, hydroponic agriculture (growing plants in water solution rather than soil) is spreading fast the world over. The nutritional requirement of the plants in this system of soilless farming is met by the nutrient mixtures, called hydroponics fertiliser mixtures, added to the water in which the plant roots are kept submerged. These mixtures are made of chemical plant nutrients. A breakthrough has now been achieved by an Indian hydroponics hobbyist in creating a purely organic nutrient mixture for growing plants in water. This wholly chemical-free plant growth solution has been tested successfully for growing several plants, including common vegetables like tomato and arbi and some high value medicinal plants like Brahmi, Arjun and Cineraria. Indeed, a good deal of research is underway in this system of soilless farming in the US and Europe but not much headway has been made anywhere in organic hydroponics. Of course, some hydroponics enthusiasts abroad have been experimenting with various kinds of organic manures and mixtures of plants, but successful and commercially viable organic hydroponics models are still not available. His daughter, Shweta Singh, a Delhi University botany student, has been assisting him in discovering and further improving the biofertiliser mixture for growing plants in ordinary water. “I will work on it for a couple of years more before thinking of launching commercial production of this bio-fertiliser for hydroponics. However, if some government organisation, such as the Indian Council of Agricultural Research (ICAR), comes forward, I am willing to cooperate with it in promoting organic hydroponics in India,” he says. He believes that nearly 200 commercially important plants can be grown by hydroponics technique.

Hydroponic Farming: Pakistan Future

To defeat food shortages in the upcoming era, Pakistan can use hydroponic farming to overcome crises of food shortage. Hydroponics can be a revolutionary technology for Pakistan to guarantee suitable and sustainable supply of vegetable. It reduces 70 percent to 90 percent less water and reduce cultivated area than irrigated soil and land based agriculture farming and gardening. No water was lost in the ground or absorbed by weeds or lost in evaporation.

[woo_product_slider id=”64262″]
With the collaboration of government and private sector, a hydroponic pilot project can be started across the country. The establishment of state-of-the-art greenhouse facility can produce hydroponic tomatoes of all varieties including tangy, elegant, cherry and others. If the hydroponic technology is properly deployed, the country could be a huge power player in the market because nobody else in the region is using high-tech hydroponics.


Hydroponic Farming- Pakistan Future 
A high tech hydroponic facility is more expensive to set up than soil farming but once it is set up, operating and maintenance costs were low and the very high and definite yields means that invested money would be recovered in one year.
The world leader’s countries in hydroponics utilize ‘cluster approach’ where land is allocated just for hydroponic farming practiced by different farmers. To develop a viable hydroponics industry, Pakistan urgently needs to improve its infrastructure facilities, such as availability of electricity and land. Greenhouses need a constant supply of power but the situation in Pakistan is not encouraging. By improving electricity facilities and establishing green house a fine chain of hydroponics farm can develop.
With more than 16 million populations, Pakistan needed to boost its agriculture performance, which was low and unpredictable compared to other major agriculture producers. If hydroponics is introduced properly, the country can triple the revenues earned on agriculture exports. The new technology also has a great potential to meet our food requirement.
