Practical Hydroponics: Kitchen garden of sweet potato (kamote) tops

Practical Hydroponics
Kitchen garden of sweet potato (kamote) tops

Dr Abe V Rotor

                      
Three-week old kitchen garden of sweet potato (kamote) tops

You can grow kamote or sweet potato tops* in the kitchen. It also serves as a greenery of sort on the window sill.


Fill to three-fourth a convenient glass jar with tap water. Place a healthy tuber on the mouth of the jar. To keep it steady, stick three pieces of toothpick like a tripod. Add water daily as roots develop. Be sure to replace water weekly to prevent mosquitoes from breeding in the jar.


In a week's time or two you can start harvesting. At first allow the tops to extend. Just clip the leaves you need in your cooking. Rotate the position of the tuber towards the source of light, so that you will have more shoots, and greener and bigger leaves.


Now you have a dish garden for a whole month or longer. You can grow fresh onion leaves with this technique. Try it on garlic.


You see, this is simple hydroponics - soil-less gardening. It is introduction to the science of hydroponics and aeroponics. For school children, why don't you try this as your project?

Read more about hydroponics and aeroponics. Happy gardening! 

Here are some of the health benefits of sweet potato leaves:

* Anti-Diabetes
* Helps in Heart Health
* Anti-mutagenic and Antioxidant
* Anticoagulant
* Enhances Eye Health
* Anti-bacterial
* Helps in Bone Health.

Post-Impressionism reflects our inner thoughts and feelings

Post-Impressionism reflects our inner thoughts and feelings 

"Post-Impressionist art is known for its bold colors, expressive images, and symbolic elements. Artists in this movement often used thick paint applications, called impasto, and painted from life. They also emphasized geometric or distorted forms, and used unnatural colors that they attributed with strong emotion." Internet quote

Paintings and Verses by Dr Abe V Rotor

Radiance from the bottom is brighter than the sky's, AVR

"Glow coming from below,
from the heart or volcano."

Rainbow seen on broken glass, AVR

"Fragmented rainbow, its arch gone,
 ROYGBIV ceases to be one."

Danaus butterflies escape winter in the North, 
converge, then return in Spring, avr. 

"Monarchs, yet heed Nature,
 in a great adventure." 

Strange colony of seaweeds on coral reef, AVR 

"Queer forest in the deep,
often seen in our sleep."

Mountaineering conquers the self more than the mountain, AVR.

"Mountain to conquer,
fear, pride and anger." 

Reproductive cells under the microscope, AVR

"Sparks of life unseen,
each carries a gene."

Fish of the same fins get together, AVR

"School of fish,
unity missed."

Edge of a forest scene one morning, AVR

"Fishing but not the catch,
under an holy arch." ~

"Post-Impressionists believed that a work of art should not revolve 
around style, process, or aesthetic approach. Instead, it should place 
emphasis on symbolism, communicating messages from the artist's 
own subconscious."

Remnant of a local Niagara Fall, AVR 

"Dry waterfall,
after the Fall."

Replica of Archaeopteryx in relief painting. 

"Archaeopteryx risen,
to modern day chicken." 

Emerging lotus from a pond at sunrise

"Glow in the murk,
sun in the dark."

"Nature is not only all that is visible to the eye... 
It also includes the inner pictures of the soul." ~

Environmental degradation is the most serious global abuse

 Environmental degradation is the most serious global abuse

Environmental degradation is the most serious global abuse, not only in pursuit of actual human need, but his unending want of affluence apparently of no end. The earth is slowly choking with deadly gases, its surface defaced and stripped of natural cover, man-made materials dumped on land and water, in fact its geography has changed and continues to be modified directly and indirectly by man.

Dr Abe V Rotor

A child's allegory of  Fishing on the Moon at Doomsday 
by Mateo M Rotor 9, author's grandson 2022. 

1. What withheld the world to shift to alternative energy was the cheap fossil fuel, virtually oozing from the ground and flowing through pipelines around the globe to feed the industrial boom and millions of cars as affluence rose to the point of ostentatious and frivolous living.  But each car’s exhaust is a miniature volcano, erupting daily, worse than a Mt Pinatubo (Philippines) and Mount St Helens (US) combined.

2. The air accumulates gaseous materials and particulates, building acid rain that turns  soil acidic and unproductive, defacing valuable works of art (historical relics and artefacts), causing illnesses heretofore  unrecorded in medical books, and triggering other diseases as well, including the resurgence of ancient diseases like tuberculosis.   
 
                     Thinning of the ozone layer over Antarctica. Ozone hole has been detected over the Arctic.  

 3. The ozone layer, a protective blanket against radiation from space is being thinned by CFC and other gases.  A hole at the southern hemisphere as big as continental USA, exposes millions, particularly children, in Australia and New Zealand to ultraviolet rays, a major cause of skin cancer.  A smaller ozone hole is building up over the Arctic region. 

4. Gases in the atmosphere trap heat from escaping, thus solar heat together with heat generated by the earth and man’s activities collectively contribute to global warming at an alarming rate.  Climate change has been the cause of climatic adversities (typhoons, tornadoes, drought, blizzards), erratic weather, and other unexplained atmospheric phenomena. 

5. In Al Gore’s “An Inconvenient Truth” the world is getting warmer and warmer at a geometric rate, far exceeding any period of the history of the earth except in its early formation.  Warming is traced to increasing amount of CO2 in the air, the principal gas of combustion mainly of fossil fuel that runs agriculture, industry, transportation, and  illuminate whole cities around the world.  

6, The failure of timely shift to alternative fuel even as fossil fuel sources are dwindling, even as alternative energy is available, even as population demand tremendously increased in the past one hundred years, has grave consequences which we are feeling today, and this is just the beginning - fuel shortage, high cost of living, increasing inequity leading to mass poverty.

7. Environmental degradation is the most serious effect, not only in meeting actual need, but unending want of affluence apparently of no end. The earth is slowly choking with deadly gases, its surface defaced and stripped of natural cover, man-made materials dumped on land and water, in fact its geography has changed and continues to be modified directly and indirectly by man. 

8. Reminiscent of the Dust Bowl of the Dakotas in the US in the early 20th century are similar desertification cases, farmlands becoming wastelands due to excessive farming and poor management, such cases include the Sahel region (Africa) struck in the 60s by extreme drought, farmlands around the shrinking Aral Sea (Russia), the source of irrigation now only a measly fraction of its original size.  AERIAL PHOTOS A comparison of Aral Sea in 1989 (left) and 2014 (right)

9. We don’t have to go far.  Our own Laguna Bay, bigger than the Sea of Galilee, is dying, its once pristine blue water as I saw it in the sixties as a UPLB trainee in a lakeshore barangay, Gatid, Sta Cruz, is now shallow and muddy as siltation and pollution from homes, farms and industries from four surrounding provinces worsen by encroaching  settlements and fishpens clogging the lake – indeed a desecration of the lake’s beauty as described in Rizal’s celebrated novel, Noli Me Tangere. 

10. All over the world lakes and rivers are dying: Lake Chad of Africa, Aral Sea of Russia, tributaries of Mississippi in the US, Nile in Egypt, Yangtze in China, Mekong in Vietnam.  Who would believe that odor of methane and hydrogen sulphide from the polluted harbour of Hongkong is the first to greet passengers even  before landing on the sprawling modern airport? So with tourists on reaching the deck of the 100-storey Sears Tower on Lake Michigan in the US. ~

Children's Books: Nature and the Classics

Children's Books 
 Nature and the Classics*
 Living with Nature Center 
San Vicente, Ilocos Sur

"Write, read Classics about Nature, and vice versa;
Reach for the highest level of arts and philosophy." - avrotor

*The word classics is derived from the Latin adjective classicus, meaning "belonging to the highest class of citizens." The word was originally used to describe the members of the Patricians, the highest class in ancient Rome.

Dr Abe V Rotor

“We still do not know one thousandth of one percent of what nature has revealed to us.” –Albert Einstein

"There is something infinitely healing in the repeated refrains of nature—the assurance that dawn comes after night, and spring after the winter." –Rachel Carson

 
"It seems to me that the natural world is the greatest source of excitement; the greatest source of visual beauty, the greatest source of intellectual interest. It is the greatest source of so much in life that makes life worth living" - David Attenborough
 
“I firmly believe that nature brings solace in all troubles.” –Anne Frank

"In every walk with nature one receives far more than he seeks." –John Muir

 
“Let the rain kiss you. Let the rain beat upon your head with silver liquid drops. Let the rain sing you a lullaby.” –Langston Hughes

 
"If you wish to know the divine, feel the wind on your face and the warm sun on your hand.” –Buddha

“The goal of life is living in agreement with nature.”- Zeno


Classics or classical studies is the study of classical antiquity. In the Western world, classics traditionally refers to the study of Ancient Greek and Roman literature and their original languages, Ancient Greek and Latin. Wikipedia

"Freedom in imagination, young as he is, while grownups yearn for expression outside the confines of art; who is the master then? " - A V Rotor

"Nothing, indeed, is more dangerous to the young artist than any conception of ideal beauty: he is constantly led by it either into weak prettiness or lifeless abstraction: whereas to touch the ideal at all, you must not strip it of vitality." - Oscar Wilde

"It is only after years of preparation that the young artist should touch color - not color used descriptively, that is, but as a means of personal expression." - Henri Matisse

You can't hide behind mask;
it is no longer Halloween;
with thin lips and sleepy eyes,
I know where you've been. ~
