(TMU) – The art and skill of creating miniature trees from the trees found in nature originated in China over a thousand years ago.
The Japanese fine-tuned the techniques and named it bonsai, which simply means ‘planted in a container’. The aim of this tradition is to grow a healthy plant that will grow into maturity but remain much smaller than the size of the same species growing in nature.

We usually grow our autoflower cannabonsai directly above the base medium and then gradually reveal the roots For this round of autos we used the transplanting technique we use with photoperiods, which ultimately affected their growth but made for some nice small cannabonsai In our Root Training handbook, we demonstrate the two distinct root techniques specifically for autoflower and photoperiod cannabonsai 👩🔬👨🔬
This is achieved by using small containers for planting and thereby restricting the plant’s ability to absorb nutrients and develop extensive root systems.
The most famous bonsai, the Japanese White Pine or the Yamaki Pine, is just under 400 years old and was trained into an exceptional Bonsai by six generations of the Yamaki family and miraculously survived the atomic bomb dropped on Hiroshima 75 years ago, on August 6, 1945, completely unscathed.
The tree is now part of a permanent exhibition at the National Bonsai & Penjing Museum in Washington DC.
In recent years, growers have experimented with creating cannabis bonsai, primarily to produce clone clippings from a mother plant.
The smaller size of the mother plant as a bonsai means many mother plants can be grown in a much smaller space, thus allowing for diversity in the cannabis garden and eliminating the need to grow from seed.
Although the basic steps for planting and training a cannabis bonsai are the same as for any tree or plant, bear in mind that soil, light, humidity, heat and water requirements differ from species to species.
YOU’LL NEED: a young cannabis plant in a pot, a drill, plastic coated wire or gardening twine, a wooden stake (or dowel). If you’re starting with a mother plant clone clipping you’ll need a pot and soil as well.
STEP ONE: PREPARE THE POT
No need for using a traditional bonsai pot, a small upright pot will be fine. Drill holes around the rim of the pot, this will be useful to help with training the plant with string or twine. Ensure the holes are big enough for the twine to fit through comfortably.
STEP TWO: PLANT YOUR CUTTING
Choose a healthy and sturdy cutting from the mother plant. Add the soil to the pot and position the cutting in the pot.
Push the wooden stake into the soil next to the main stem of the cutting and be careful not to damage any roots. The stake can be used to position the trunk of the bonsai to any position you want it to grow, with the help of the twine and the holes drilled in the pot. Don’t tie the trunk with too much force, and leave some room for the trunk to grow in width.
STEP THREE: TIME TO TRAIN
Train the branches as you did the stem, by tying them in the position you choose with the twine using the drilled holes. To create horizontal branches they will need to be tied down tighter and less tight for the vertical. Be gentle so as not to damage or snap the branches. The branches should be allowed to be grown without too much restriction.
STEP FOUR: PRUNING
To keep the classic bonsai shape and allow airflow to the plant’s main stem it’s important to keep the stature and prune to only the offshoot branches. Cutting the main branches could affect the health and growth of the plant severely.
At this stage the jury is still out on how long bonsai mother trees should be kept active. Since they can be kept in a vegetative stage indefinitely, they could technically keep going for as long as they are alive. However, growers have found that pure indica’s degrade faster and sativa’s last longer.
Currently, as a general rule, indica’s are replaced every 3–4 years, hybrids every 4–5 years, and sativa’s every 5–6 years. However, the strain and the quality of care the plant receives will no doubt impact its lifespan.
WHICH STRAINS ARE BEST FOR CANNABIS BONSAI TREES?
The genetics of each strain is different and those strains with shorter stature are likely to be more suitable for developing into cannabis bonsai.
Two strains with a short stature that might be ideal for developing into bonsai are Critical Kush and White Widow.
Critical Kush, an indica dominant hybrid, grows short and bushy because of its 80:20 indica/sativa ratio. The high THC content has excellent relaxing and sedative properties.
White Widow, a legendary Dutch classic strain is a well-balanced hybrid with a potent mix of sativa and indica. THC levels are above 20%.
Scientists Thrilled by Discovery of Rare, Mammoth 400-Year-Old Coral
A massive 400-year-old hard coral discovered on the Great Barrier Reef has scientists expressing their sense of surprise and excitement.
Named Muga dambhi by the Manbarra people, the Indigenous group who have traditionally taken care of the land, the “exceptionally large” brown and cream-colored coral is located off the coast of Goolboodi or Orpheus Island in the Great Barrier Reef.
It is believed that the coral was spawned some 421 to 438 years ago, meaning that its age predates the arrival of Captain James Cook and the advent of colonization in Australia, notes the Guardian.
The spectacular coral is about 35 feet wide and over 17 feet high, and is double the size of the nearest coral.
Scientists and members of the community participating in a marine science course discovered the specimen earlier this year.
While not the largest coral in the world, the huge find is of major significance to the local ecosystem, according to Adam Smith, an adjunct professor at James Cook University who wrote the field note on the find.
“It’s like a block of apartments,” Smith said. “It attracts other species. There’s other corals, there’s fish, there’s other animals around that use it for shelter or for feeding, so it’s pretty important for them.”
“It’s a bit like finding a giant redwood tree in the middle of a botanic gardens,” he added.
It is likely that the coral hasn’t been discovered for such a long time due to its location in a relatively remote and unvisited portion of a Marine National Park zone that enjoys a high degree of protection.
“Over the last 20 or 30 years, no one has noticed, or observed, or thought it newsworthy enough to share photos, or document, or do research on this giant coral,” Smith said.
The coral is in remarkable condition, with over 70 percent of its surface covered in live coral, coral rock and microalgae. No disease, bleaching or recently deceased coral has been recorded on the specimen.
“The cumulative impact of almost 100 bleaching events and up to 80 major cyclones over a period of four centuries, plus declining nearshore water quality contextualise the high resilience of this Porites coral,” the field note added.
The specific coral has been given the name Muga dhambi, meaning big coral, out of respect for the Indigenous knowledge, language, and culture of the Manbarra Traditional Owners.
Greenland Ice Washed Away as Summit Sees Rain for First Time in Recorded History
For the first time in recorded history, torrential downpours of rain have struck Greenland’s icy summit nearly two miles above sea level.
Greenland, an environmentally sensitive island, is typically known for its majestic ice sheet and snowy climate, but this is fast changing due to a massive melt taking place this summer.
However, the typical snowfall has been replaced in recent years not simply by a few showers, but by heavy rainfall. The torrential downpour last week was so huge, in fact, that it washed away a terrifying amount of ice across some 337,000 square miles of the ice shelf’s surface, reports Earther.
Temperatures at the ice shelf had simultaneously warmed to a significant degree, with the summit reaching 33 degrees Fahrenheit – within a degree above freezing and the third time that the shelf has surpassed freezing temperatures this decade.
The fact that rain is falling on ice rather than snow is also significant because it is melting ice across much of southern Greenland, which already saw huge melting events last month, while hastening rising sea levels that threaten to submerge whole coastal cities and communities.
To make matters worse, any new ice formed by the freezing rainwater will not last long. The ice shelf currently existing on Greenland was formed by the compression of snow over innumerable years, which shines bright white and reflects sunlight away rather than absorbing it, as ice from frozen rain does.
The huge scale of the melt and accompanying rainfall illustrate the growing peril of rapidly warming climate conditions across the globe.
“This event by itself does not have a huge impact, but it’s indicative of the increasing extent, duration, and intensity of melting on Greenland,” wrote Ted Scambos, a senior research scientist at the National Snow and Ice Data Center at the University of Colorado. “Like the heat wave in the [U.S. Pacific] northwest, it’s something that’s hard to imagine without the influence of global climate change.”
“Greenland, like the rest of the world, is changing,” Scambos told the Washington Post. “We now see three melting events in a decade in Greenland — and before 1990, that happened about once every 150 years. And now rainfall: in an area where rain never fell.”
South Korean Toilet Turns Poo Into Green Energy and Pays Its Users Digital Cash
What if your morning #2 not only powered your stove to cook your eggs, but also allowed you to pay for your coffee and pastry on the way to class?
It seems like an absurd question, but one university in South Korea has invented a toilet that allows human excrement to not only be used for clean power, but also dumps a bit of digital currency into your wallet that can be exchanged for some fruit or cup noodles at the campus canteen, reports Reuters.
The BeeVi toilet – short for Bee-Vision – was designed by urban and environmental engineering professor Cho Jae-weon of the Ulsan National Institute of Science and Technology (UNIST), and is meant to not only save resources but also reward students for their feces.
The toilet is designed to first deliver your excrement into a special underground tank, reducing water use, before microorganisms break the waste down into methane, a clean source of energy that can power the numerous appliances that dorm life requires.
“If we think out of the box, feces has precious value to make energy and manure,” Cho explained. “I have put this value into ecological circulation.”
The toilet can transform approximately a pound of solid human waste – roughly the average amount people poop per day – into some 50 liters of methane gas, said Cho. That’s about enough to generate half a kilowatt hour of electricity, enough to transport a student throughout campus for some of their school day.
Cho has even devised a special virtual currency for the BeeVi toilet called Ggool, or honey in Korean. Users of the toilet can expect to earn 10 Ggool per day, covering some of the many expenses students rack up on campus every day.
Students have given the new system glowing reviews, and don’t even mind discussing their bodily functions at lunchtime – even expressing their hopes to use their fecal credits to purchase books.
