pH is a term used to describe the measurement of how alkaline or acidic something is. In the case of hydroponic gardening, it means how acidic or alkaline the nutrient solution or growing medium is. Plant nutrient uptake is what nutrients the plant takes up. How much plants take up is dependent on the solution being within a certain pH range. Most pH ranges are often around 5.5 to 6.2.

pH stands for potential of hydrogen. Every 1/10th increase in pH brings about a 10 times increase in oxygen. While most products attempt to balance to the pH of skin (5.2 to 5.6) TVI products which are highly oxygenated and near-perfectly charged have a pH of between 7 to 8.5, or doing the math, are hundreds to thousands of times more oxygenated than others. No wonder The Vital Image users have such beautiful skin. Back to Top

The acidity and alkalinity of a substance is referred to as its pH value. A neutral substance has a pH of 7, a substance with a pH above 7 is considered alkaline and a substance with a pH below 7 is considered acid. The term acidosis is used to describe a state of excess acidity in the body fluids whereby the term alkalosis describes a state of excess alkalinity.

pH is a measure of the acidity ("sourness") or alkalinity ("sweetness") of soil. The scale ranges from 1 to 14, but few soils are more acidic that 5 or more alkaline than 9. A pH of 7 is perfectly neutral, but most plants grow best when the pH is a slightly acidic between 6.5. Soils in areas with low rainfall tend to be alkaline. Where rainfall is high, soils are more often acidic. This happens because rainfall gradually washes calcium from soil.

Hi, I'm doing a science project on hydroponic farming, using the Water Culture method, i need to know how to get the best results, especially with pea plants & carrots, if anyone can give me some advice, than post it on the bulletin board, please address it to J.S. of Fl hi ! i am interested in starting a hydroponic vegetable garden as a business, what size should the garden be to be commercially viable ? would appreciate a reply.

If you are interested in experimenting with one or more of the most likely candidate bioenergy species in your area, you can start by gaining some working knowledge of growth characteristics and management responses under local conditions - this will be useful if a later opportunity for commercial production and sale of biomass occurs in your area.

I would like to know the source for seeds that are recommended in Howard Resh's book Questions and Answers. I have a small hydroponic hobby setup and do not wish to buy a hugh amount of seeds. Can you help me. Hello Ron -- please comment on the potential of using pvc gray pipes (plastic electrical conduit pipes) for 2-liter hydroponic systems. Those pipes are UV-protected, but I am wondering if they are safe compared to Schedule 40 pvc pipes. Hope to hear from you soon.

Answer: Limestone and sea shells are both composed of Calcium Carbonate, which will react with Phosphorus in your nutrient solution and precipitate out as insoluble Calcium Phosphate, which is not freely available to your plants. Thus, using limestone or sea shells as a medium is not a good idea. If you think you have some limestone in your medium, here is how to test for it.

It is well known that the body fluids of healthy people tend to be more alkaline (high pH) and the body fluids of sick or diseased people are acidic ( low pH). Healthy blood, spinal fluid and saliva are normally at a pH of 7.4. This alkaline state is necessary for cell growth, cell function and cell repair. It has been proven that cancer cannot grow in an alkaline solution because an alkaline solution will hold oxygen at a high level (Cause and Prevention of Cancer, Biochem Zeits, 152: 514-520).

The timer turns the pump on. The pump sitting in the nutrient solution reservoir pumps the solution up the hose to the garden to supply the plant roots with food. The plant roots will use as much nutrient as it needs and the rest is returned back to the reservoir for the next feeding. Determined by your timer setting. About every 15 minutes. The overflow pipe keeps the water from rising to high in the cups. This is the ebb and flow or flood and drain hydroponic system. I am a first time grower.

There is no typical set-up, but depending on which system and configuration you choose, the various elements could include: a reservoir (to hold water and nutrients), grow trays or grow pots (to hold the plants and/or grow media), grow media, a water pump, and a timer.

You can ferment Kombucha in a dark or in a light place. It is best not to grow it in direct sunlight because that may destroy some of the beneficial bacteria needed to produce Kombucha Tea. The temperature where the Kombucha Tea is being fermented should remain between 75-85° F. If it gets too cool it will take longer to ferment.

hello, my class is learning about hydroponics. Like how they work and stuff like that.Right now we are growing lettuces the hydroponic way.the way we are doing it is we have a container with stones with our lettuces in it we the lettuces up the top and the roots hiding under the stones and another container with the water and when we put them together the roots dangle in the water and we have a straw to blow bubbles.

i am new to this site and i have a question: first of all, please don't mind my bad english. i am from holland, you know. if i build, let's say the 11 bottle hydroponic system, and i turn on the pump and fill the system with water/nutrients, then what happens? does the water drain off just like an ebb & flow system, or does the waterlevel drop because the plants absorb it? i can imagine the water running back through the pump after it is switshed off.

i am doing a project on the effect of ph levels of water on the growth of hydroponic plants and i need help...e-mail me at guardangel2005@aol.com thanx-melissa hello first what a great site, Second i am a chef and I am trying to grow a hydroponic herb garden. Basil, mint, sage, chives, parsley, and maybe some heirloom tomatoes. All my plants keep dying and i dont think i have the correct fertilizer. Can you grow these plants hydropontically and what I am dong wrong.

There is much confusion in regard to pH. What is most important is the reserve potential of alkaline or acid pH not the number itself. Therefore, an alkaline number of 10 or even 11 with a low reserve number (measurement of potential to do work) will not harm anyone, or anything. An acid product made with a plant enzyme that has a pH 1.8 is as safe for human skin as say 2% boric acid is for eyes because the acid reserve number is very low.

pH is a measure of the acid / alkaline balance of the water, for which 7 is neutral, below is acid, above is alkaline. The water tested is at the point of abstraction ? that is in the borehole.

The pH needs to be in a proper range in order for the nutrients to be available to the plant. The optimum soil pH for boxwood is between 6.5 and 7.2. If the pH is below the recommended range, add dolomitic lime. This lime has low oxide content and will persist in the soil for 4‑7 years depending on application rates and soil type. If the pH is above 7.5, then lowering the pH would be in order. This is accomplished by adding iron sulfate.
