  1. Gorilla Girl F1 Fast Version® This is a photoperiod-dependent, feminised and ultrafast flowering version of Gorilla Girl® (SWS74), the most potent “Super Strong” strain in the Sweet Seeds® catalogue with THC levels of up to 31%. It is a cross between the potent Gorilla Girl® and our own Sweet Gelato Auto® (SWS76). The plants have a very strong and stimulating effect with a THC content as high as 25%, some plants may even exceed these levels. This strain is known for its exuberant resin production which completely coats the calyxes with aromatic trichomes. The buds have an intense, sweet and fruity aroma and taste, with tones of blue cypress and wood complemented by citric, earthy shades. Variety SWS86 Indica: 40% / Sativa: 60% THC: 18-25% · CBD:0,1% Indoor Yield: 400-550 g/m2 Outdoor Yield: 350-600 g/plant Indoor Harvest: 7 weeks Outdoor Harvest: early September
  2. Science Reveals The Cannabis Industry’s Greatest Lie: You’re Buying Weed Wrong (And So Is Everyone Else) There’s much more to cannabis than THC—for solid proof, look no further than the CBD boom—but when it comes to moving product on the legal recreational market, only two numbers matter: the list price, and the THC content. Super-potent cannabis flower, with THC percentages of 25 percent and up, dominate dispensary shelves. High-THC cannabis will sell out very quickly while lower-percentage weed gathers dust. When cannabis tests at more than 25 percent THC, dispensaries can justify charging $75 or more for a store-bought eighth—because there’s a very good chance people will pay it, confident that they’re taking home the best and most potent weed available. If the weed’s in the teens, well, it had better be cheap. The problem is that this is all wrong. All of it. THC shopping is almost as bad and dumb as buying wine based on how cool the label looks (which is also how some people buy weed). Not only does THC content have nothing to do with how “good” the weed is, as recent research conducted by the University of Colorado and published in JAMA Psychiatry found, THC content is also a poor indicator of potency. High-THC weed doesn’t even get you “more high”! Researchers at the University of Colorado at Boulder’s Institute of Cognitive Science documented the experiences of 121 cannabis users. Half the study participants were users of cannabis concentrates—very-high THC cannabis extracts—and the other half preferred cannabis flower. Both groups received cannabis at varying “strengths”: flower users tried cannabis flower at either 16 percent or 24 percent THC, and extract users received oil at either 70 percent or 90 percent THC. Researchers checked study participants’ blood and monitored their mood, cognitive function, and intoxication level before, immediately after, and one hour after use. As the researchers expected, the concentrate users had very high levels of THC in their bodies after use. But they weren’t “more high.” In fact, every participants’ self-reported “highness” was about the same—“as were their measures of balance and cognitive impairment,” as CU noted in a news release. Medium THC flower, high-THC flower—all the same high! This was not what the researchers were expecting. “People in the high concentration group were much less compromised than we thought they would be,” said coauthor Kent Hutchinson, a professor of psychology who studies addiction, in a CU news release. “If we gave people that high a concentration of alcohol it would have been a different story.” Consider the cannabis flower users. Sixteen percent THC compared to 24 percent THC is a big difference—50 percent “stronger.” How can users of such differnet “strength” products report such similar psychoactive effects? The short answer is a theory that cannabis connoisseurs and cannabis scientists have been saying for years: There are many more factors at play than THC. Put slightly longer: Judging a cannabis strain on its THC content is not unlike judging a film based on the lead actor. The THC number isn’t going to be an indicator of the performance. (One very large exception to this: edibles. If one edible says it has 100 milligrams of THC, and another says it has 10 milligrams, and you eat the 100, you will absolutely be higher, longer, than if you ate the 10.) There are a host of cannabinoids, including CBD as well as more than 100 others—most of which aren’t even tested for. (Even if they were, would the average buyer know what to do?) There are also aromatic compounds called terpenes that dictate how cannabis affects the mind and body. All of these work in concert, a phenomenon known as “the entourage effect.” This is why synthetic THC simply didn’t have the same medical effects as smoking weed. A good way—maybe the best way—to determine if cannabis will be good, or at least good for you, is to smell it. But in legal markets like California, that’s now impossible. Pot is sold in prepackaged containers. And the coronavirus pandemic eliminated what limited opportunities there were to smell cannabis. Some shops let you wave under your nose a designated “smell jar”—a few buds in a container with a perforated lid. No longer. But back to THC numbers. Cannabis researchers know it’s not an indicator. Cannabis growers and sellers know it’s bogus. And yet, here we are. The market simply hasn’t caught on—and merchants, by putting high-THC cannabis out on the shelves to satisfy the misdirected market demand, are ensuring that the misunderstanding continues. “It’s a shame,” said Neil Dellacava, the co-founder of Gold Seal, a San Francisco-based cannabis brand that specializes in high-end flower. “I find stuff that’s absolutely amazing that I have to throw in the trash because it tests at 18 or 19 percent.” At that level, despite “an amazing terpene profile, the best smoke I’ve ever had” simply will not sell, he said. “People just don’t understand,” he added. “When people go shopping, they look for two things: they’re looking for price, and they’re looking for THC percentage.” The THC fallacy persists despite everyone’s best efforts. Both Instagram influencers as well as cannabis entrepreneurs and advocates have tried to explain that the THC number is, at best, a rough estimate (and a number that, depending on the lab that came up with it, might be inflated or suspect). With this much momentum, it’s unlikely science will change anything. It will take a long time for buyers to adjust their habits and realize THC content isn’t like alcohol by volume on a beer label after all. Until they do, connoisseurs can take advantage of the market inefficiency, and take home superior pot with lower THC levels at a reduced price. It will just require a little more work on the consumer’s end. But it will also require cultivators of lower THC, higher-high weed to have demand high enough to keep them in business, and that’s far from guaranteed. https://www.forbes.com/sites/chrisroberts/2020/06/16/science-reveals-the-cannabis-industrys-greatest-lie-youre-buying-weed-wrong-and-so-is-everyone-else/ associated link https://www.colorado.edu/today/2020/06/10/marijuana-concentrates-sharply-spike-thc-levels-dont-necessarily-get-users-higher
  3. 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
  4. Hey all Got this Auto Amnesia from Seedsman. Nearly at 10 weeks from pop but it has no trichomes and no smell. Seems no definitive reason for this to happen. All other strains before and at same time, as usual, grow nice dense, sparkly, stinky bud. Any knowledge? Much appreciated... Pics to follow.

  7. Cannabis reverses ageing processes in the brain Researchers at the University of Bonn restore the memory performance of Methuselah mice to a juvenile stage Memory performance decreases with increasing age. Cannabis can reverse these ageing processes in the brain. This was shown in mice by scientists at the University of Bonn with their colleagues at The Hebrew University of Jerusalem (Israel). Old animals were able to regress to the state of two-month-old mice with a prolonged low-dose treatment with a cannabis active ingredient. This opens up new options, for instance, when it comes to treating dementia. The results are now presented in the journal Nature Medicine. Like any other organ, our brain ages. As a result, cognitive ability also decreases with increasing age. This can be noticed, for instance, in that it becomes more difficult to learn new things or devote attention to several things at the same time. This process is normal, but can also promote dementia. Researchers have long been looking for ways to slow down or even reverse this process. Scientists at the University of Bonn and The Hebrew University of Jerusalem (Israel) have now achieved this in mice. These animals have a relatively short life expectancy in nature and display pronounced cognitive deficits even at twelve months of age. The researchers administered a small quantity of THC, the active ingredient in the hemp plant (cannabis), to mice aged two, twelve and 18 months over a period of four weeks. Afterwards, they tested learning capacity and memory performance in the animals – including, for instance, orientation skills and the recognition of other mice. Mice who were only given a placebo displayed natural age-dependent learning and memory losses. In contrast, the cognitive functions of the animals treated with cannabis were just as good as the two-month-old control animals. “The treatment completely reversed the loss of performance in the old animals,” reported Prof. Andreas Zimmer from the Institute of Molecular Psychiatry at the University of Bonn and member of the Cluster of Excellence ImmunoSensation. Years of meticulous research This treatment success is the result of years of meticulous research. First of all, the scientists discovered that the brain ages much faster when mice do not possess any functional receptors for THC. These cannabinoid 1 (CB1) receptors are proteins to which the substances dock and thus trigger a signal chain. CB1 is also the reason for the intoxicating effect of THC in cannabis products, such as hashish or marihuana, which accumulate at the receptor. THC imitates the effect of cannabinoids produced naturally in the body, which fulfil important functions in the brain. “With increasing age, the quantity of the cannabinoids naturally formed in the brain reduces,” says Prof. Zimmer. “When the activity of the cannabinoid system declines, we find rapid ageing in the brain.” To discover precisely what effect the THC treatment has in old mice, the researchers examined the brain tissue and gene activity of the treated mice. The findings were surprising: the molecular signature no longer corresponded to that of old animals, but was instead very similar to that of young animals. The number of links between the nerve cells in the brain also increased again, which is an important prerequisite for learning ability. “It looked as though the THC treatment turned back the molecular clock,” says Zimmer. Next step: clinical trial on humans A low dose of the administered THC was chosen so that there was no intoxicating effect in the mice. Cannabis products are already permitted as medications, for instance as pain relief. As a next step, the researchers want to conduct a clinical trial to investigate whether THC also reverses ageing processes in the brain in humans and can increase cognitive ability. The North Rhine-Westphalia science minister Svenja Schulze appeared thrilled by the study: “The promotion of knowledge-led research is indispensable, as it is the breeding ground for all matters relating to application. Although there is a long path from mice to humans, I feel extremely positive about the prospect that THC could be used to treat dementia, for instance.” Publication: A chronic low dose of delta9-tetrahydrocannabinol (THC) restores cognitive function in old mice, Nature Medicine, DOI: 10.1038/nm.4311 Media contact: Prof. Andreas Zimmer Institute of Molecular Psychiatry University of Bonn Tel. +49 (0)228/6885300 sauce THC good!
  8. Hi We have a new video on our Vimeo channel... Green Poison XL Auto®: We hope you enjoy it! jaypp
  9. Morning all, i always do greenhouse grows as i work away too much and an indoor grow is a no go. I normally grow autos as to be fair they need very little care although i tend to do 1 or 2 fems just see how they go. This year, as always, i have Sweet Seeds as i have yet to have a failed grow and have only ever lost 2 seeds due to not sprouting along with very uniform plants. This year i have 2 each of Mohan Ram, Black Cream, Blow Mind, Cream Mandarine, S.A.D. Will be 3 phased runs of this over the year with the last chop in September'ish weather dependent. On top of this i had a few freebies around so i thought why not use them up - 2 x G13 Auto Gigabub, 2 x THC Seeds Berry Bomb. All seeds were popped mid March and spent a few weeks under a cfl then popped in a warming house outdoor for a week to let them acclimatise to the colautos being uniform as alwayser temps, yes i know its early but i want a 3 phase planting so made an early start All look very healthy with the Sweet Seeds being like sets of twins other than the Blow Mind that look the complete opposite and to be fair i struggled with them last year too. The big surprise is thatthe GigaBud and the Berry Bomb are awesome looking, being bushier, taller and well into the fluffy top stage !! The SS have started but nowhere near as far on. The SS is generally the first to show and furthest on ! Very surprised. The Berry Bomb looks simply stunning yet its a breeder i generally wouldnt give a secong look, very happy and may do some more. My fems this year will be 2 x Samsara Holy Grail 69's and 2 x Delicious Seeds Sugar Black Rose fast version and finally 2 x Blimburn Grandaddy Purple. Having never done them and getting them as freebies i thought why not Hopefully it will be a decent year and be able to put some stock into the jars. Anyone having done any of the above mentioned outdoors please chime in with feedback Pics to follow. Thanks
  10. Hi everyone. I'm new here (Registered mainly for this specific post but after having browsed the site, I'll be sticking around) I'm about to start making THC Capsules (CannaCaps). I've had a bit of experience making a few homemade goodies before but these seem a bit more complicated to make (specifically with dosage). I have all the equipment needed for the process but I need some advice or clarification on how potent the caps may be. I've done a lot of research prior to this post but the conclusion is, unless you get the product lab tested, you'll never know for sure how much mg of THC is in a capsule. The weed I have supplied is said to contain roughly 15% THC per gram (Which is 150mg THC per gram) so once decarboxylated and added to either 1 or 2 teaspoons of extra virgin coconut oil and baked I'd roughly want to create 10 capsules which I estimated would have around 11-12mg of THC per capsule. Doe's this sound about right? I'm only an occasional weed user so I wouldn't want something that completely messes me up but people I'll be introducing to capsules are everyday smokers so I want something that'll give them a high also so it's finding the correct balance. I know these things are usually trial and error but hopefully someone on here can maybe cut out some of the errors and make it a smoother process. Cheers
  11. I've heard a couple of people claim that pollinating a single flower site on a female will globally increase it's resin production greatly.... Has anyone here done this to notable effect? interested in potentially taking this on as a breeding method....
  12. I don't need no thought control.......Sorry, got ahead of myself there. What if? If I'm just looking for the medicinal benefits and not really looking to get high, would I skip the decarboxolation step? I read that THCa has all the medicinal attributes of THC without the stony, but I'm not sure it's true. I need all the cannaboids, terpenes, all the factors that help with pain, but I need to function too. Thoughts? Respect.........As Always Cmoon

  14. The FDA Quietly Approved a Synthetic Form of Marijuana as Medicine Though FDA's stance on marijuana has remained notoriously under wraps, the government agency recently embraced the drug's main psychoactive ingredient. Last month, the agency approved Syndros, a synthetic form of THC, for treatment of ailments suffered by AIDS and Cancer patients. What is Syndros?Even though it's just now making headlines, Syndros is really nothing new, Motherboard reports; it's merely a liquid version of the drug Marinol, which was approved in 1985 as a synthetic cannabinoid pill, to treat the same conditions as Syndros. What are the advantages of Syndros over marijuana? Researchers have suggested that heavy marijuana use "could exacerbate the course of illness in patients who have schizophrenia," the New York Times reports. However as Paul Armentano, deputy director of the National Organization for the Reform of Marijuana Laws, points out to ATTN:, "none of those warnings appear on the warnings of synthetic THC." What are the drawbacks of synthetic THC? The answer to this question boils down to the "entourage effect," as it's been dubbed. The botanical version of marijuana flaunts a number of positive side effects that are absent in its synthetic versions, which contain only THC. As Armentano explains, "Some of the plant's components are greater than the individual parts." Why does the FDA approve of synthetic THC but not marijuana? Armentano says it's rare for the FDA to approve or reject a botanical drug for therapeutic use, but not completely unheard of. He explains that it's not up to the FDA to reschedule or deschedule marijuana; that falls in the realm of the DEA. What the FDA does do is green-light clinical trials for drugs; however, the agency rarely receives applications for trials on marijuana. "There is no inducement for private pharmaceutical companies to invest hundreds of millions of dollars on a drug they would have no proprietary control over," he explains. They have no control over it because they can't legally grow it or market it because of its federal Schedule 1 status. Still, the FDA's current stance on marijuana is not one pro-marijuana crusaders would be happy with. Michael Felberbaum, press officer for the FDA, tells ATTN: via email: What do marijuana advocates think of synthetic THC?"The FDA has not approved any product containing or derived from botanical marijuana for any indication. ... the FDA has not found any such product to be safe or effective for the treatment of any disease or condition." Ultimately, groups like NORML simply want patients to have access to marijuana in whatever form best aligns with their medical needs. Armentano tells ATTN: "I think patients ought to have the legal option to choose which therapy is safest, most efficient, and most cost-effective for their particular needs. ... Patients should have access to a wide range of cannabis-specific products, including access to herbal cannabis." http://www.attn.com/stories/10340/fda-approves-thc-liquid-form
