Hydroponics Gardening - An Introduction To Hydroponics Gardening For Beginners (Part 5) Plant Growth


There are three classes of plants. Each of these classes metabolize in a different way. The first class are succulent plants called CAM. These plants like low light and high humidity levels and so thrive indoors, in bathrooms and kitchen areas.

The second class of plants is called C4. These plants grow in hot arid regions and are very efficient at using both Carbon Dioxide (CO2) and Sunlight. Most C4 plants are grasses.

The third and last class of plants are called C3. These plants join two 3-Carbon atoms together to produce sugar. The chemical formula for sugar is C6H12O6 which is 6 Carbon, 12 Hydrogen and 6 Oxygen atoms stuck together. Most of our favourite plants are to be found in this class.


Like all living things, plants breathe 24 hours a day. In order to make energy each plant cell respires (converts plant sugar to energy). The plant uses Oxygen (O2) and expires, or breathes out, Carbon Dioxide (CO2).

In the same way that energy moves around the human body, so water, nutrients and plant sugars are continually being transported around the plant body. The leaves create a circular flow with the roots. This circulation occurs when the leaves draw up, water from the roots, through their Xylem.

These are straw like cells found in the plant stem. The water continually evaporating from the leaves sucks up more water from the roots and creates the internal water pressure that keeps the plant rigid. Thus if the plant is deprived of water, as in a drought, it loses its rigidity and begins to wilt when the internal pressure drops.

The leaves return energy to the roots in the form of sugar solutions. These are transported from the leaves via the plants Phloem. These are also straw like cells found in the plant stem. In this way the leaves exchange sugars for water and nutrients, while the roots exchange water and nutrients for sugar solutions. This liquid circulation is constant and continuous throughout the life of the plant.


The 3 main parts of a plant are the Roots, the Stems and the Leaves. Each of these parts is of great importance and any problem that arises in any of them will be a major one. The most sensitive part is the roots, as well as being the most difficult to see should a problem occur.

The Roots:

The miracle of growth starts at the roots. As already mentioned, roots transport nutrients up to their leaves and plant sugars are returned by the leaves. The roots also act as storerooms for the excess sugars that are produced by the leaves. These sugars are stored in the form of starch. The size of the root ball and therefore the amount of starch that can be stored, determines the success of the plant in terms of growth and productivity.

The size of the root system is directly affected by the amount of moisture, the temperature, the available Oxygen and the supply of plant sugars being transported down from the leaves. According to Graham Reinders, in his book "How to Supercharge Your Garden", a research Rye plant in a 12 inch pot was said to have had 14 billion root hairs. These hairs would have stretched 6200 miles (nearly 10,000 km) if placed end to end and covered an area of 180ft by 180ft (about 55m by 55m). The greater the root system is the more energy (starch) it will be able to store and so, the more nutrients it will be able to send up to nourish the leaves. The plant will then have the capability to grow stronger. The end result of this is that the leaves will be able to pass more plant sugars back down to the roots and so the cycle continues.

Another factor to be taken into account is the root medium. Plants take their nourishment from the medium surrounding their roots. It stands to reason that the less energy the plant has to expend in order to get that nourishment the more energy it will have available to use for growth and nutrient exchange with its leaves. Because a plant takes most of its water in via its roots, (the root hairs trapping the water molecules surrounding it) and transpires about 99% of that water out via its leaves, it will wilt and fall over if its roots cannot extract enough water out of its surrounding medium.

A plant growing in the ground will take its moisture from the surrounding soil. This moisture normally gets into the soil as rain and the plant absorbs that rain and the nutrients that have dissolved in it, via its root hairs. After the rain has stopped the topsoil quickly dries out as the water filters into the ground. Because of this drying out the plant has developed a means of absorbing Oxygen via its upper roots. The top third of the roots become specialized as "Air Roots" while the bottom third becomes specialized as "Water Roots".

It is vital to ensure that the Air Roots are not kept constantly wet as this will result in the plant drowning. The Water Roots however, may be kept wet all the time, providing that the water has sufficient Oxygen dissolved in it. Insufficient Oxygen will result in roots with brown, discoloured root tips and subsequent infections. Healthy roots are a crisp, white looking structure.

The plant is quite capable of healthy living with the roots exposed to light as long as they remain moist. However, light will encourage the growth of Algae which will cause odours. The Algae will also compete with the plant for Oxygen during the dark periods and nutrients in the light ones. This, of course will mean the plant has to work harder in order to produce sufficient sugars for its needs. The Oxygen produced during the dark periods is used to help the roots convert these sugars, from the leaves, into energy (Starch).

In The News:

Tracking the progress of the third party testing we at PES are coordinating along with U-Plug Products LLC, of their 2 kW U-Plug magnet motor that is a 24"x6" portable cylinder weighing 20 pounds, expected to cost 2,000 USD. We want to run it three times longer (21 hours) than what the best batteries available could provide. (PESWiki; February-April 2016)
Pre-launch video announces a new LENR website coming March 1, 2016 at http://LookingForHeat.com The video is very well done as an entertaining piece that hopefully will go viral. (Free Energy Blog; February 21, 2016)
It's not easy to find a qualified testing agency that is also willing to sign off on something that appears to defy our existing understanding of the laws of physics. U-Plug has agreed to allow for a group of us scientists, including at least 3 PhDs to go test their unit and publish our report. (PESN; February 20, 2016)
So that this is quite clear, this is a test on a Regular Torch. NOT the ELFE flashlight. This is to compare them. 2 x NiMH AA 1.2v Battery's in a Regular Torch with a Halogen Bulb. Load is 2.8v and 0.85amps. (PESN; February 17, 2016)
Video explains the scientific principles behind how the ELFE flashlight harnesses endless free energy from the environment (Earth's magnetic field), which works better in some regions than others. It also shows the insides the torch. Uses the word "antennae," as one of the components. (PESN; February 14, 2016)
"The OPhone contains a capacitor that directly powers our phone. During extensive use this capacitor may become discharged, however this capacitor is being constantly trickle charged by Orbo. So after a period of time the capacitor will be recharged and the phone will be functional again. In essence the phone is charging itself." (Free Energy Blog; February 13, 2016)
The company that has figured out how to harness the earth's magnetic field to produce usable power and has been selling the ELFE flashlight (two more customer reports), is now developing a 3 kW generator. In two weeks, they are holding a business meeting for international distributors. (PESN; February 12, 2016)
Illinois company is gearing up to manufacture a 2 kW (115 volts, 17.3 amps) magnet motor that is load-following, portable, 24"x6" tube, weighing 20 pounds, very quiet, with 3-year warranty but expected to last at least 20 years with zero maintenance. Third-party tested. MSRP 2000 USD, beginning March, 2016, through distributors. (PESWiki; February 11, 2016)
The government agent who worked on this technology five decades ago, that is similar to Professor Steven E. Jones' Joule Ringer, thinks it is conceivable that we could eventually scale this solid state technology up to have a device the size and price of an air conditioner providing 20 kw. (PESWiki; February 9, 2016)
Nagendra Singh in Mumbai, India, informs us that they have built five of these and have two running for customers presently, in the 40 kVA range. "Presently it is too [expensive], costing 3200 USD per kva below 30 kva." (PESWiki; February 8, 2016)
The SunCell is described as a solid state "Sun in a Box." A 200 kW module would weigh around 250 pounds, with energy production cost being around 1 cent/kwh, so return on investment could be ten days. They are expected to be available commercially by Q1, 2017. (PESN; January 6, 2015)
"Today I received my Elfe Flashlight and it works. Time will tell if it meets the claims of automatically recharging, when depleted. If it holds, the claims a real breakthrough in FE technologie would have been accomplished." -- German customer (PESWiki; February 6, 2016)
The phone battery indicator stays near full even with heavy usage throughout the day. (The battery is charged by the internal OCube that pulls energy from the wheelwork of nature, solid state). (PESWiki; February 5, 2016)
The capacity of the Proton-3ND (Proton -3 Nano Diffusion) battery is projected to be 44 times the capacity of lithium batteries. Electric vehicles with these batteries would have more power and much more mileage at no extra charge. (PESN; January 4, 2016)
HH2 water fuel cell creates pure hydrogen off a 9-volt battery. This was a big diesel HH2 cell that was tested on a 16-liter Cat engine for CARB testing; yet it ran on very low amps and a low 9 volts. (PESWiki; February 3, 2016)
A former U.S. Government worker describes his effort to bring to public awareness (by highlighting things presently in the public domain) energy and anti-gravity technologies that the government had operational 50 years ago but has kept from the public. (PESN; February 2, 2016)
Imagine an incandescent bulb that is actually more efficient than LEDs! Well, it actually exists (MIT) and it does so by recycling light. (Free Energy Blog; February 2, 2016)
SMBC-Comics.com has posted a fun spoof on our skeptics. (Free Energy Blog; February 1, 2016)
"OK, so a lot of people are asking what's the difference between an Orbo power cell and traditional batteries." Batteries store energy, Orbo generates energy, then trickle charges a lithium ion battery.] (Free Energy Blog; February 1, 2016)
Mr. Keshe is as misleading in the field of free energy as he is regarding me. That has been my experience the years I've been exposedto his work. He takes something and blows it so far out of proportion that it barely resembles the fact from which it was extrapolated into infinity. He demands: "Close PESWiki now." (PESWiki; January 31, 2016)
They have achieved solid state operation using an electromagnetic pump to spray the molten silver between the electrodes for the 1000/second continuous pulsing for continuous power production. (Free Energy Blog; January 29, 2016)
