  1. Hi all. I've just noticed one of my 2 week old Criticals seems to have self topped itself with 4 leaves at the top with two double leaves? Has this every happened to anyone else? There's no problems just never seen it before. Any thoughts? DPG
  2. Been having a peruse on the site and have come across two CBD strains. I saw that one is identified as Sativa and the other Indica. What is the difference for a CBD rich plant? Without the psychoactive properties, what are we looking for? Any guidance would be grand
  3. https://medicalxpress.com/news/2019-06-genes-cannabis-disorder.html A large team of researchers with members from Denmark, Iceland and the U.S. has isolated a gene associated with cannabis use disorder (CUD). In their paper published in the journal Nature Neuroscience, the group describes their genome-wide association study surrounding CUD and what they found. For many years, users of cannabis claimed that it was not addictive. More recent research has suggested that such claims are both right and wrong. Most people who consume cannabis do not become addicted, but some do. Prior research has found that approximately 10 percent of users have CUD—when they stop using cannabis, they experience withdrawal symptoms similar in some respects to withdrawal from other drugs. Symptoms include cravings and engaging in behavior to fulfill their need. This finding has added evidence to theories that there is a genetic component involved in addiction. In this new effort, the researchers sought to find that possible genetic component for CUD. To isolate the possible gene or genes involved, the researchers tapped into a European genome database to compare the genomes of 2,000 people known to have CUD against another 50,000 people who it was assumed did not have the condition. The researchers found a gene variant called CHRNA2. The team followed up those findings by carrying out the same kind of comparison with an Icelandic database—in that instance, they were able to compare the genomes of 5,500 people who had CUD against 30,0000 controls. They report that they found the same result—the gene variant CHRNA2. The researchers are quick to point out that having the gene does not turn someone into a pot smoker—instead, it makes them more likely to become addicted to it if they start using it. They also note that they believe the gene they isolated is likely one among several that are involved in cannabis addiction. But they suggest that their findings could contribute to other studies that seek to understand the nature of addiction and perhaps lead to a treatment for people with CUD who are struggling with their addiction.
  4. https://phys.org/news/2019-05-genetic-differences-cannabis-strains.html Research from Washington State University could provide government regulators with powerful new tools for addressing a bevy of commercial claims and other concerns as non-medical marijuana, hemp and CBD products become more commonplace. The new analysis of the genetic and chemical characteristics of cannabis is believed to be the first thorough examination of its kind. The current method is inadequate, says Mark Lange, a professor in WSU's Institute for Biological Chemistry. Regulators focus on levels of the psychoactive compound THC and just a handful of the more than 90 other cannabinoids. The industry makes various claims about different strains, from sedating indicas to invigorating sativas, Acapulco Gold to Zkittlez, but they defy objective analysis. "There is a reason why all these strains have different names—because a lot of them are very different," said Lange. "But some strains with different names are actually very similar. The bottom line is there is a lot of confusion." Until now. Lange and his colleagues analyzed genetic sequences from nine commercial cannabis strains and found distinct gene networks orchestrating each strain's production of cannabinoid resins and terpenes, volatile compounds behind the plant's powerful aroma. Their research was published today in the journal Plant Physiology. Armed with this new tool, people can start to sort out a variety of issues that are already emerging as recreational cannabis is legal in 11 states, including the entire West Coast, and hemp is legal across the country. Lange's analytical method, for example, can be used to clearly delineate between psychoactive cannabis and hemp, which by law has to have less than 0.3 percent THC. It might help identify the skunky smell that elicits complaints from the neighbors of pot farms, opening a way to breed and grow something easier on the nose. It can test the health claims of cannabidiol, known by the shorthand CBD, or the alleged synergy, known as the "entourage effect," between cannabis compounds. It can truth squad your bud tender. "One of the things that needs to happen in the emerging market is that you know what you're selling," said Lange. "You can't just call it something and then that's good. We need to be very clear that this is the cannabinoid profile that is associated with, say, Harlequin -it has a specific cannabinoid profile, a specific terpenoid profile, and that's what it is. If it has a different name, then it should have a different profile. Currently you can do whatever you want." Lange is an expert on trichomes, the resin-producing glands of plants like mint. But in this case, he could not touch the plant if he was to comply with federal and university policy on cannabis research. All the material was handled by EVIO Labs, a private cannabis testing company licensed by the Oregon Liquor Control Commission. Anthony Smith, an EVIO biochemist and co-author, drew RNA from each strain by abrading trichomes with glass beads and filtering the material. A third party sequenced the RNA. In the end, Lange and his team touched only a high-resolution data set that clearly marks both the genes of each strain and their end products.
  5. What strains everyone growing at the minute? im currently running Casey jones incredible bulk sour pink grapefruit almost week 6 flower stacking up nicely let me know what your all growing
  6. Hey new member here looking at what strain to do next and im set on a cookies strain but im having trouble finding the best ones ? i know barneys farm and royal queen has released cookie fem seeds, has anyone tried or in the process of these ? i know bsb has a cali cookies and im running their diesel now but im not sure. im set on humbolts lemn garlic og, a cookies strain and maybe something else to fill my tent out with. Maybe some freebies they always throw in but id rather stick with something more legit. any recommendations would be nice
  7. Just thought I would share this here as I'm sure a few people will find this very interesting and informative. enjoy Phylos Galaxy Phylos has the world’s largest database of cannabis DNA featuring the genetic identity of thousands of varieties from over 80 countries. The Phylos Galaxy is a 3D population genetics visualization of this data, offering the public unprecedented scientific insight into varieties that, until now, have only been categorized by street names. Anyone can submit a variety to the Galaxy with Phylos Genotype, a DNA sequencing test that offers permanent placement in the Galaxy, a “living” digital genetic report that updates in real time, and digital marketing tools to share your exciting varieties with the world. The Cannabis Evolution Project The Cannabis Evolution Project was a two-year collaboration with Rob Desalle, a curator and phylogeneticist at the American Museum of Natural History. Thousands of ancient and modern cannabis samples were collected from around the world, and serve as the foundation for the Galaxy you see today. We’re still working hard to tell the evolutionary story of this diverse and amazing plant. How does it work? Each node, or star, in the Phylos Galaxy represents a single cannabis plant. The distances between nodes show how similar they are. The lines show how related they are. Samples that share a lot of genetic variants will be very close, and different genetic populations are represented by colors. How did you make the Galaxy? We sequenced the DNA of over a thousand cannabis plants and compared them. We mapped those relationships into three dimensions using Principal Components Analysis, a well-established technique in the field of population genetics. We combined this approach with other statistical genetics methods that generate “heredity lines” connecting closely related samples. Then, we made an interactive visualization. These techniques have never before been used to visualize a single species. Why is Phylos sequencing the DNA of different Cannabis varieties? We want to know how Cannabis has evolved, what its history was like, and how it has co-evolved with humans. We want to know what domestication does to the shape of evolution, and to better understand the complex diversity of hybrid strains. We’re investigating where they came from, why they’re so different, and what makes each one unique. And most importantly, we want consumers and patients to finally know what they’re getting and be able to find it again without relying on inaccurate names. http://www.phylosbioscience.com/the-phylos-galaxy/

  9. Hi all, Hopefully someone an help me!? Q: Does my Short and Sweet Auto Feminised seedling have TMV?1st two pics below show my concern: I am new here, and a "bit" flustered by this potentially contagious/yield fatal virus, especially as everything else seems to be going so well...(so far)I am happy to provide any further info if needed..I'm afraid that the virus may spread to the others if I leave this one in the tent! Please help me! More info about my grow: Hi everyone, new farmer here who has been following the many incredibly useful threads on 420 for quite some time now...silently in the shadows no more as I need some desperate assistance from you expert growers...I have a 1x1x2M tent setup with X4 15 litre airpots and X4 different strains of autoflower for my first attempt.I am running 900 watt equivalent full spectrum LED panels (X2 450w equiv / 200w actual draw each), as well as a pair of 120cm Sunblaster T5's with nano reflectors vertically on either side.Active intake with filter, 350m3 extractor with Rhino pro scrubber. Good negative pressure.My readings are 24 - 26 deg celcius, with a regulated RH of 60%I have noticed one of my 8 day old since breaking soil seedlings is a bit Mottled and today after watering, one of the main leaves has a crinkle in it, a slight curl of one of the serrated side tips and isnt looking great. It has been treated exactly the same as the other 3 plants, 2 of which are growing at a great rate - 1 is nearly 5inches across its helicopter blades and looking very healthy as are the other 2.The strains Im growing:1: Green Crack Auto Fem (AKA Green Cush/NYC Diesel hybrid)2: Amphetamine Auto Fem3: Cash Crop Auto Femand lastly the suspected plant which may have TMV?4: Short and Sweet Auto FemI have attached a few pics and would greatly appreciate your help as I dont want all my other babies in my first ever grow to get infected if it is a virus!Other info:1st pic - Today (Day 8 from breaking soil)2nd, 3rd, 4th pic (4 days from breaking soil) - Seemed to have mottled appearance when very youngThen a few pics of my setup - this has now changed slightly with oscillating fan, larger extractor, more lights, humidifier, etc..etc...but for the most part that is how my tent looks.Never fed them any nutes, just Canno Pro soil, Canna Coco, Bat Guano, Perilite, Vermiculite mix with well rinsed Canna clay pebbles on the top.I leave my soft tap water to sit in the tent at tent temps for 48-72hrs at least to evaporate the Chlorine and then PH to approx 6.6 with PH Down and add Canna Rhiztonic at half strength. Thats all they have had so far. Watering about every other day, been misting in between as my RH was down at 35-40% until yesterday when I added an automated humidifier setup to maintain 60% RH. This resulted in all the plants perking up and much accelerated growth.Temps are 24 - 27 degrees Celsius for the most part, slightly lower at night as my intake is from outside, but the 2 LED panels keep it warm and I vent scrubbed air inside into second carbon filter to keep RH in the tent..working well so far.Lighting schedule 24/0 for the duration.Many thanks,Saint
  10. The Rise of Marijuana™ (Patent Pending) To the cannabis industry, a patent granted last August was either doomsday or the dawn of a new era, depending on who you asked. U.S. Patent No. 9095554 covered the “compositions and methods for the breeding, production, processing and use of specialty cannabis.” Filed by a group of California marijuana growers, it covers any cannabis plants with a certain chemical profile, including THC (the main psychoactive chemical in marijuana) and terpenes (the molecules that give different varieties their distinctive odors). Although the government had issued patents on certain compounds derived from the cannabis plant, this was the first time a patent had been issued for the plant itself. “It’s seen as the big guys versus the little guys. There are a lot of people who are afraid of Big Ag and Big Pharma coming in and taking over,” says Jennifer Martin, a cannabis grower and consultant. colorado-weed In a grow house in Colorado, marijuana is raised for sale in legal dispensaries. The patent comes as social norms around marijuana are loosening and cash-strapped states turn to the drug to alleviate their budget crises. Today, 20 states have legalized medical marijuana, and pot has become a business valued at $6.7 billion. Although the federal government still classifies cannabis as a Schedule I drug with “no accepted medical use,” the industry’s reach—and revenue—is still expected to climb as more states loosen their restrictions on the drug. As the industry’s supply chain has transitioned from underground growers to legally recognized suppliers, it has caught the attention of scientists and entrepreneurs interested in cataloging and capitalizing on marijuana’s medicinal potential. “A lot of people are afraid of Big Ag and Big Pharma coming in and taking over.” In 2011, a group of Canadian scientists published the first full genome sequence of the marijuana strain Purple Kush. In the five years since, both researchers and biotech firms have begun classifying and standardizing marijuana strains so that customers may one day walk into any marijuana dispensary around the country and know that the Girl Scout Cookies strain they bought last week is the same one they’re buying today. The results are transforming the cannabis industry into a potentially high-tech, high-stakes business. Meanwhile, long-term breeders like Martin fear that if small-time hobbyists can’t compete, they’ll lose the soul of the industry to the likes of Monsanto and Pfizer. These fears have led scientists like Mowgli Holmes of Phylos Biosciences to use DNA sequencing to document as many existing strains as possible and release them into the public domain in an attempt to block more possible patents. “Whether it wants to or not, the cannabis industry needs to start looking at itself as an agricultural industry. But it’s also a pharma industry. We have a very uniquely placed plant,” says Reggie Gaudino, vice president of scientific operations at Steep Hill Labs in California. http://www.pbs.org/wgbh/nova/next/evolution/patenting-pot/ (check link for full article)
