Hydroponics is a subset of hydroculture, which is a method of growing plants without soil, by instead using mineral nutrient solutions in a water solvent.Terrestrial plants may be grown with only their roots exposed to the nutritious liquid, or the roots may be physically supported by an inert medium such as perlite, gravel.Despite inert media, roots can cause changes of the rhizosphere pH and root exudates can impact the rhizosphere biology. The nutrients used in hydroponic systems can come from an array of different sources, including (but not limited to) fish excrement, duck manure, purchased chemical fertilisers, or artificial nutrient solutions. Plants commonly grown hydroponically on inert media include tomatoes, peppers, cucumbers, lettuces, marijuana, and model plants like Arabidopsis thaliana. Hydroponics offer many advantages, one of them being a decrease in water usage for agriculture. To grow 1 kilogram of tomatoes in Intensive farming requires 400 liters of water, in hydroponics 70 liters of water, and only 20 liters of water for aeroponics.Because of the lack of water needed to grow produce, it would be possible in the future for harsh environments which don’t have much accessible water, to be able to grow their own food.
The earliest published work on growing terrestrial plants without soil was the 1627 book Sylva Sylvarum or 'A Natural History' by Francis Bacon, printed a year after his death. Water culture became a popular research technique after that. In 1699, John Woodward published his water culture experiments with spearmint. He found that plants in less-pure water sources grew better than plants in distilled water. By 1842, a list of nine elements believed to be essential for plant growth had been compiled, and the discoveries of German botanists Julius von Sachs and Wilhelm Knop, in the years 1859-1875, resulted in a development of the technique of soilless cultivation.Growth of terrestrial plants without soil in mineral nutrient solutions was called solution culture. It quickly became a standard research and teaching technique and is still widely used. Solution culture is, now considered, a type of hydroponics where there is an inert medium.

Hello, everybody,today we're going to give you some tips on how to grow cucumbers.
1. Choose a right size flowerpot and fertile soil, and place the soil in the flowerpot. 2. Put the seeds in the pot and water the good seeds to make sure they have enough water. 3. Apply organic fertilizer to the seeds so that the cucumber can get enough nourishment. 4. Place the seeds in a sunny place for enough sunlight.
Cucumbers contain less than 5 percent sugar and are rich in dietary fiber. According to studies, dietary fiber can improve the sensitivity of insulin receptors in human body and improve the utilization of insulin in human body.At the same time, dietary fiber itself is a kind of polysaccharide, and can not be broken down, equivalent to a part of the food space in the human body.This is a good substitute for many diabetic patients who need to reduce their diet. In addition, when fiber enters the body, it will also wrap up part of the sugar in the food, making the speed of sugar absorption slow, which can effectively regulate the postprandial blood glucose balance.

A cherry blossom is a flower of many trees of genus Prunus. The most well-known species is the Japanese cherry, Prunus serrulata, which is commonly called sakura (桜 or 櫻; さくら). They are widely distributed, especially in the temperate zone of the Northern Hemisphere including Japan, Taiwan, Korea, Mainland China, Nepal, India, Pakistan, Afghanistan, Iran, Myanmar, Thailand and West Siberia.Along with the chrysanthemum, the cherry blossom is considered the national flower of Japan. All varieties of cherry blossom trees produce small, unpalatable fruit or edible cherries. Edible cherries generally come from cultivars of the related species Prunus avium and Prunus cerasus.
In Japan, cherry blossoms symbolize clouds due to their nature of blooming en masse, besides being an enduring metaphor for the ephemeral nature of life, an aspect of Japanese cultural tradition that is often associated with Buddhist influence, and which is embodied in the concept of mono no aware.The association of the cherry blossom with mono no aware dates back to 18th-century scholar Motoori Norinaga. The transience of the blossoms, the exquisite beauty and volatility, has often been associated with mortality and graceful and readily acceptance of destiny and karma; for this reason, cherry blossoms are richly symbolic, and have been utilized often in Japanese art, manga, anime, and film, as well as at musical performances for ambient effect. There is at least one popular folk song, originally meant for the shakuhachi (bamboo flute), titled "Sakura", and several pop songs. The flower is also represented on all manner of consumer goods in Japan, including kimono, stationery, and dishware.
The most popular variety of cherry blossom in Japan is the Somei Yoshino. Its flowers are nearly pure white, tinged with the palest pink, especially near the stem. They bloom and usually fall within a week, before the leaves come out. Therefore, the trees look nearly white from top to bottom. The variety takes its name from the village of Somei (now part of Toshima in Tokyo). It was developed in the mid- to late-19th century at the end of the Edo period and the beginning of the Meiji period. The Somei Yoshino is so widely associated with cherry blossoms that jidaigeki and other works of fiction often depict the variety in the Edo period or earlier; such depictions are anachronisms. Winter sakura or fuyuzakura (Prunus subhirtella autumnalis) begins to bloom in the fall and continues blooming sporadically throughout the winter. It is said to be a cross between edohiganzakura, the Tokyo Higan cherry (P. incisa) and mamezakura (P. pendula). Other categories include yamazakura, yaezakura, and shidarezakura. The yaezakura have large flowers, thick with rich pink petals. The shidarezakura, or weeping cherry, has branches that fall like those of a weeping willow, bearing cascades of pink flowers.

Hello everyone, today we are going to talk about how to grow succulent plants.
* Soil Succulents are suitable for use in soils that are permeable to water and air, dry, sterile and insect-free. A mixture of perlite and coconut bran (1:2) is recommended for most succulents. *Illumination When raising succulent plant indoors, place it in the window with sufficient sunshine or balcony aptly.If the summer temperature is too high, you can use a shading net with a 70% shading rate, and avoid 12-15 hours of sun exposure. *Moisture The principle of succulent plant watering is to water less and thoroughly,and avoid accumulating water. Spring and fall are the growing seasons for succulents, and the best time to water is when the leaves below begin to dry out. Summer is the dormancy season of succulent plants, mainly by spray watering, keep the surface of the basin soil wet.Water less often in winter.
*Temperature Succulents are native to South Africa, where the optimum growth temperature is between 12 and 28 degrees Celsius. Therefore, the spring and autumn are the most vigorous seasons for succulents.Make sure the room temperature is above 8 degrees Celsius in winter and below 35 degrees Celsius in summer, and pay attention to ventilation and cooling. Hope those tips may help you! Enjoying your plant!

What is Succulent?
In botany, succulent plants, also known as succulents, are plants with parts that are thickened, fleshy and engorged, usually to retain water in arid climates or soil conditions. The word "succulent" comes from the Latin word sucus, meaning juice, or sap.Succulent plants may store water in various structures, such as leaves and stems. Some definitions also include roots, thus geophytes that survive unfavorable periods by dying back to underground storage organs may be regarded as succulents. In horticultural use, the term "succulent" is sometimes used in a way which excludes plants that botanists would regard as succulents, such as cacti. Succulents are often grown as ornamental plants because of their striking and unusual appearance, as well as their ability to thrive with relatively minimal care.
Many plant families have multiple succulents found within them (over 25 plant families).In some families, such as Aizoaceae, Cactaceae, and Crassulaceae, most species are succulents. The habitats of these water preserving plants are often in areas with high temperatures and low rainfall, such as deserts. Succulents have the ability to thrive on limited water sources, such as mist and dew, which makes them equipped to survive in an ecosystem which contains scarce water sources.
In next part, we are going to discuss on how to plant succulent!

Hello everybody, welcome back to our channel! Today we are going to give you some tips on how to grow tomatoes. *Temperature: 24℃-26℃ *Sowing time:July & August *Adequate illumination *Drain away water in time *Disinfect the seed: During disinfection, wrap the seeds with gauze and soak them in 50℃ water for 10 minutes, or soak them in 10% sodium phosphate solution for 20 minutes.Rinse with clean water and soak in 30℃ warm water for 23 hours.Get the dry stuff out.
*Prepare a shelf to prop up the development and stay upright *If the first flower doesn't bear fruit, the plant won't be able to bear fruit until the leaves are full. A tomato flower has both the stamen and the pistil, and there is no natural pollination medium. To make the fruit fuller,it need our help by gently tapping the flower with a finger or cotton swab. *Before and after flowering, lateral buds will grow out of the leaf base. The lateral buds below the first tidbits should be removed in time so as not to consume nutrients. *When the red fruit is fully ripe, cut and harvest from below. The ripe fruit tends to split or fall off, so don't harvest too late.

“It is the time you have wasted for your rose that makes your rose so important.” “You're beautiful, but you're empty...One couldn't die for you. Of course, an ordinary passerby would think my rose looked just like you. But my rose, all on her own, is more important than all of you together, since she's the one I've watered. Since she's the one I put under glass, since she's the one I sheltered behind the screen. Since she's the one for whom I killed the caterpillars (except the two or three butterflies). Since she's the one I listened to when she complained, or when she boasted, or even sometimes when she said nothing at all. Since she's my rose.” ― Antoine de Saint-Exupéry, The Little Prince
“We can complain because rose bushes have thorns, or rejoice because thorns have roses.” ― Alphonse Karr, A Tour Round My Garden “Did you hear about the rose that grew from a crack in the concrete? Proving nature's laws wrong, it learned to walk without having feet. Funny, it seems to by keeping it's dreams; it learned to breathe fresh air. Long live the rose that grew from concrete when no one else even cared.” ― Tupac Shakur, The Rose That Grew from Concrete “It was June, and the world smelled of roses. The sunshine was like powdered gold over the grassy hillside.” ― Maud Hart Lovelace, Betsy-Tacy and Tib “I feel as if I had opened a book and found roses of yesterday sweet and fragrant, between its leaves.” ― L.M. Montgomery, Anne of the Island
“Feeling at peace, however fragilely, made it easy to slip into the visionary end of the dark-sight. The rose shadows said that they loved the sun, but that they also loved the dark, where their roots grew through the lightless mystery of the earth. The roses said: You do not have to choose. ” ― Robin McKinley, Sunshine “Love is like the wild rose-briar; Friendship like the holly-tree. The holly is dark when the rose-briar blooms, but which will bloom most constantly?” ― Emily Brontë, The Complete Poems “Princess,” he whispered against her ear. “My beautiful, beautiful princess. I want to spoil you. Pamper you. Indulge you.” ― Teresa Medeiros, A Whisper of Roses “An idealist is one who, on noticing that a rose smells better than a cabbage, concludes that it makes a better soup.” ― H.L. Mencken, A Book of Burlesques

Hello everybody, welcome back to our channel! Today we are going to teach you how to grow delicious grapes at home. Here are 7 steps to go: 1. Plant your grapevines. Depending on the species of grapes you are planting, spacing will be different for each plant. For American and European grapes, plant each vine 6–10 feet (1.8–3.0 m) apart. Muscadines require much more space, and should be planted approximately 16 feet (4.9 m) apart. Plant the cuttings in a trench with the basal and center bud covered. The top bud should be just above the soil surface. Press the soil firmly around the newly planted grapevine cuttings. 2. Give your plants a good watering. Grapevines don’t prefer heavy water or rain, so after the first watering keep the amount of water you give them to a minimum. Keep water near the roots so that the majority of it gets absorbed rather than evaporated by the sun. If your area doesn’t get much rain, set up a drip system directly at the roots so that the grapevines get small amounts of water on a regular basis.
3. Prune your grapevines. The first year, the grapevine should not be allowed to produce any fully matured fruits as these can damage the young vine with their weight. Cut back all the fruit, as well as all the vines except for the strongest that branch off the cane. In later years prune as needed following established local practices, and prune back 90% of the new growth on older vines each year. 4. Prune vines when dormant. Always always prune grapevines when they are dormant. They will otherwise bleed their sap - losing vigour. This is typically in late winter when it is no longer cold enough to frost outside.
5. Mulch around the vines. A layer of mulch around your plants will regulate soil temperature, retain water, and reduce weeds. 6. Apply pest control as needed. Little pest control is needed as grapevines are naturally hardy. Keep weeds at bay by hand-weeding on a regular basis, and cover you grapevines in bird net to keep birds away if necessary. Seek guidance from your local gardening club or agricultural extension on how to combat the Vine Moth. It is one of the few pests that can decimate grapevines. 7. Harvest your grapes when appropriate. Strong, edible fruit likely won’t appear for anywhere from 1-3 years. When it appears, test its ripeness by picking a few grapes from different areas and tasting them. If the grapes are sweet, start picking as they ready for harvesting and eating. source:wikihow
Hope you can enjoy a fine harvest!

Aquarians are born between January 21st and February 19th, and belong to the Air element of the zodiac. The Air sign posse are the "Big Brain Charlies" of the star signs; analytical, objective, clever annndd, well, a TEENY bit chilly. They don't do feelings, no thank you very much.
Orchids are the flowers that are popularly known to be gifted to the Aquarius. As reported by the popular horoscope websites & experts, those with the zodiac flower sign of the orchid are curious and inventive. While the orchids are believed to be the symbol of respect, dignity, innocence, femininity, grace, joy and happiness, orchids has several other meanings as well mainly due to the wide range of colors available in this stunning flowers.
How to grow Orchids? Select a species of orchid. Some orchids are easier to grow than others. Cattleya, Phalaenopsis and Paphiopedilum orchids are amongst the easiest to grow and are recommended for most beginner gardeners and orchid growers. There are, however, believed to be over 40,000 species of orchid species — that's two times the amount of existing bird species and four times the amount of existing mammalian species. There's almost literally an orchid for any type of person. Choose the right kind of soil for your orchids. Some first-time orchid growers make the mistake of assuming that orchids need to be potted in soil like other blooming flowers, choosing potting soil as a conduit. That would likely kill your orchid. Most orchid roots need far more air than potting soil would give them, but they still need something to anchor their roots, and so they benefit from a looser, more porous mix. Try a potting mix, or combination of several different mediums. For simplicity's sake, you can make two basic kinds of potting mixes that will work for most kinds of orchids. Make sure to add water to your mix and strain it before using for best results. Choose a snug pot for your orchid unless it is large. Many orchids are comfortable being root-bound. Choose a smaller pot to place your orchid in, making sure that there are plenty of holes in the pot itself for drainage. Make sure to avoid decorative pots as well because the glaze is harmful to orchids. Pot your orchid. Remove the orchid from its original pot, making sure to cut off any dead or rotting roots. Divide the root matter into several different sections, if needed, before placing the plant in its pot. Know when to re-pot your orchids. In general, you will need to repot your orchid every two years or whenever you notice that the lower leaves have died. You may also need to repot your orchid if the plant outgrows its pot or if the roots are dying.

Bonsai is a Japanese art form using cultivation techniques to produce, in containers, small trees that mimic the shape and scale of full size trees. Similar practices exist in other cultures, including the Chinese tradition of penzai or penjing from which the art originated, and the miniature living landscapes of Vietnamese Hòn Non Bộ. The Japanese tradition dates back over a thousand years.
The Japanese loanword "bonsai" has become an umbrella term in English, attached to many forms of potted or other plants, and also on occasion to other living and non-living things. According to Stephen Orr in The New York Times, "the term should be reserved for plants that are grown in shallow containers following the precise tenets of bonsai pruning and training, resulting in an artful miniature replica of a full-grown tree in nature." In the most restrictive sense, "bonsai" refers to miniaturized, container-grown trees adhering to Japanese tradition and principles. Purposes of bonsai are primarily contemplation for the viewer, and the pleasant exercise of effort and ingenuity for the grower. By contrast with other plant cultivation practices, bonsai is not intended for production of food or for medicine. Instead, bonsai practice focuses on long-term cultivation and shaping of one or more small trees growing in a container.
A bonsai is created beginning with a specimen of source material. This may be a cutting, seedling, or small tree of a species suitable for bonsai development. Bonsai can be created from nearly any perennial woody-stemmed tree or shrub species that produces true branches and can be cultivated to remain small through pot confinement with crown and root pruning. Some species are popular as bonsai material because they have characteristics, such as small leaves or needles, that make them appropriate for the compact visual scope of bonsai. The source specimen is shaped to be relatively small and to meet the aesthetic standards of bonsai. When the candidate bonsai nears its planned final size it is planted in a display pot, usually one designed for bonsai display in one of a few accepted shapes and proportions. From that point forward, its growth is restricted by the pot environment. Throughout the year, the bonsai is shaped to limit growth, redistribute foliar vigor to areas requiring further development, and meet the artist's detailed design.
The practice of bonsai is sometimes confused with dwarfing, but dwarfing generally refers to research, discovery, or creation of plants that are permanent, genetic miniatures of existing species. Plant dwarfing often uses selective breeding or genetic engineering to create dwarf cultivars. Bonsai does not require genetically dwarfed trees, but rather depends on growing small trees from regular stock and seeds. Bonsai uses cultivation techniques like pruning, root reduction, potting, defoliation, and grafting to produce small trees that mimic the shape and style of mature, full-size trees.
