Day 2. Opened the cabinet round 6am and #1 was trying to push it's way out. Checked again at 5pm and #1 and #3 have sprouted. To be honest, I was expecting #3 to be a problem as when it germinated it looked a bit funny. Seed cracked open completely and the tail was very small. Haven't given any more water since I put the seeds in soil and put domes over them. Here's hoping for females next. Sent from my DRA-LX5 using Tapatalk2 points

Those leaves are very dark green, think there might be some Nitrogen tox as well. Leaf tip curling may point to a rootzone issue. 1. What medium is the plant in. 2. What nutes were used. Need some opinions from the indoor guys.2 points

Whatsup brothers An update on the grow. I think the seeds sprouted around the 27/28th of August, so the little girls are about 2 weeks old now going into their third week. The Platinum OG never made it through, so I only have the Banana Kush, Bruce Banner and Sunset Sherbet from this batch. Excuse the poor photography, hopefully I get better at it Banana Kush Bruce Banner Sunset Sherbet2 points

To properly stabalize a strain you need to repeat the process up to f5 depending on the plants genetics and what it was interbred with previously. Hopefully you don't discover any unwanted recessive traits like hermaphroditism or a genetic weakness to powdry mildew. Unwanted males are destroyed immediately, minimizing the risk of foreign cross pollination. Females that dont make the breeding cut, can be flowered out if they look good enough.2 points

https://weedmaps.com/news/2020/08/an-in-depth-look-at-the-study-that-discovered-thcp-a-cannabinoid-more-potent-than-thc/ A new cannabinoid has been discovered, and the ramifications could be massive. Scientists funded by the UNIHEMP research project have discovered a new psychoactive molecule: Δ9-Tetrahydrocannabiphorol, or THCP; and they believe that there are great scientific implications for the phytocannabinoid. Phytocannabinoids are cannabinoid molecules that are specifically produced by plants. There are several types of cannabinoids, including endocannabinoids, synthetic cannabinoids, and phytocannabinoids. Endocannabinoids are compounds that are produced within the body by an organism's endocannabinoid system; and synthetic cannabinoids are man-made chemicals that cannot be found in nature. Phytocannabinoids, on the other hand, are a different beast altogether. They are those that naturally occur in plants and are found in a variety, including echinacea. However, the plant species in which phytocannabinoids are most prominent is cannabis. Because of cannabis' status as a Schedule I controlled substance in the US, there are several barriers that prohibit the scientific study of the plant and its constituents. Thus, a considerable portion of cannabis research takes place abroad. Many clinical and laboratory studies of cannabis take place in Israel and Canada, where there is federal research funding to support this work; but, the newly discovered THCP was characterized by a group of Italian scientists. Unlike the US, government funding for cannabis research is relatively commonplace in Europe. The discovery of THCP was enabled by the UNIHEMP project, which is sponsored by the European Regional Development Fund. A multi-disciplinary team of Italian scientists was responsible for the discovery of this novel cannabinoid, led by Giuseppe Cannazza of the University of Modena and Reggio Emilia. The researchers' findings were published in late 2019 in the journal Nature. THCP is 33-times more active than THC Throughout the duration of the project, the group studied a medicinal cannabis cultivar, dubbed FM2, which was supplied by the Military Chemical Pharmaceutical Institute in Florence. Using a variety of scientific characterization techniques, the researchers observed two novel cannabinoids, THCP and CBDP, and isolated them from other cannabinoids that were present. Following this discovery, the group artificially synthesized THCP and CBDP to create reference materials, and the synthesized versions were successfully used to verify the natural expression of the two cannabinoids in the FM2 cultivar. After the confirmation of the identity of the two cannabinoids, the group turned its focus to THCP. To study the compound, they pursued an in vitro experiment with cultured cells. This experiment tested the binding affinity of THCP with CB1 and CB2 receptors, using synthetic cannabinoids as reference materials. It was shown that, when comparing THCP-related results to the previously reported data of other cannabinoids against the CB1 receptor, THCP is 33-times more active than delta-9 THC. This finding is critical because the group also found that the chemical was present in FM2 at 0.0029%, whereas THC was found to be expressed at 3.9%; so, even in smaller amounts, THCP is more active than THC. They also tested the cannabimimetic activity of the molecule. Cannabimimetic activity is a measure of how well a substance replicates the effects of more well-characterized cannabinoids which bind to the CB1 receptor. An in vivo experiment involving mice was performed. Herein, the influence of THCP on body temperature, spontaneous activity, immobility, and pain was determined — the results of these tests confirmed that THCP acts similarly to other cannabinoids like delta-9 THC. Will THCP be important? According to the study, even at lower doses, THCP has more cannabimimetic activity than THC. Further, the group posits that THCP could account for the wide variability of patient responses in cannabis-based therapies, even amongst cultivars with equal THC doses. This means that cannabis' psychotropic effects, which the scientific community attributes to THC, may actually be due to the presence of THCP. Unfortunately, none of the original researchers could be reached for comment. However, experts in the field do have varying opinions regarding the study. Dr. Cecilia J. Hillard of the Medical College of Wisconsin said, “I think it is well designed.” She goes on, “[The study] has two important gaps, in my opinion. First, they should have compared the in vivo effects of THCP to that of THC 'head to head' so that relative potencies could be assessed. Second, I would like to know whether THCP has greater efficacy to activate the [CB1 receptor] in particular. THC is relatively safe because it has low efficacy at the receptor. If THCP has high efficacy (like the synthetic analogs that have also increased the tail length), it is a more concerning finding, as it would suggest that strains making a lot of THCP could be more dangerous to use than those that do not.” Expanding on how THCP could be more dangerous, Hillard continued, “The so-called 'spice' compounds are synthetic agonists of the CB1 receptor. They are full agonists, meaning that they are very strong activators of the CB1 receptor. Compared to THC, these drugs have significant adverse effects and produce significant dependence (addiction). So, my issue is that we do not know yet whether THCP is like THC, a partial agonist, or like the synthetic compounds, a full agonist. And my concern is that, if it is the latter, cannabis strains high in THCP will have more adverse effects than those that are low.” Dr. Samuel Banister of The University of Sydney states, “[The study] was well designed and executed,” concurring with Dr. Hillard. However, he goes on to disagree with the group's assessment that THCP may account for the variability of psychotropic effects across various cannabis cultivars: “While this possibility cannot be ruled out, the known potency differences for THC and THCP at cannabinoid receptors is relatively small, while the difference in abundance of each in cannabis is enormous. The same is true of CBD and CBDP, although CBD requires even higher doses to achieve many of its pharmacological effects. For this reason, I do not feel that minor or trace phytocannabinoids like THCP or CBDP contribute significantly to the psychoactive effects of different cannabis strains.” How this novel cannabinoid plays out in both medical and recreational use is yet to be determined, as much more research is needed. Nonetheless, this new evidence suggests that analytical laboratories in US regulated markets may need to expand their testing panel to include THCP.1 point

Hi If anyone is interested I have a very good 2nd hand paperback of the Cannabis Breeders Bible by Greg Green. The deal also includes 20 regular seeds ( Seedsman ) of afghani indica ( 10 ) and skunk #1 ( 10 ) seeds. Just thought this would be a nice package for anyone wanting to get into breeding. Let me know if you are interested.1 point

Living soil with organic nutes, shouldn't be seeing those symtoms - if you stick to the dosages. I tried ph'ing my feeds in soil once.....my girls didnt like it, never again. With a smaller amount of medium the plant might get rootbound quicker, but I doubt it'll affect it that badly. Transplanting(carefully) is an option to consider.1 point

No no don't try it . Just to be on the save side, when I said PM I mean powdery mildew. Last season I had to deal with it and it wasn't fun. And last season was also the first season that I had to water in the evening too, as it got so hot during the day. I think I got powdery mildew on some plants because I watered in the evening. This season I'll get bigger pots, only water in the morning and if necessary I'll do a bit of defoliation to hopefully prevent PM in future.1 point

That's what I've been thinking. I'm always gonna have the space and patience to try. But if you look at some of the comments is it worth trying with half decent seeds. And a big sorry to the hijack of the thread. I'll try to behave [emoji6] Sent from my DRA-LX5 using Tapatalk1 point

@BluntKnife, you can mix 1-2 tea spoons of epsom salt with 4 liter of water. I found this info on the Royal Queen seeds website, which I think is a trustworthy source. Of course you water your autoflower with less so you would need to amend the amount of epsom needed accordingly.1 point

This little lady was my test subject, which I used to try out the germinating process and growing it before going out and buying seeds etc. I got lucky and it was a female (I think), but my other test subject turned out to be a male. So pulled that one out. She sprouted about the 7th of July, give or take. So she is about 9/10 weeks old. I know this isnt part of my official first grow plants, but if you can give any advice on her as well please Strain, it is either Kandy Kush or 24k Gold, not sure exactly as I didnt take notice which one was which when I planted them. So the one was the male which was pulled out1 point

Hi @BluntKnife, so this is the patient. To me this looks like a Magnesium deficiency. If that's the case (wait for other opinions too) you can fix it with Epsom salt. I am a bit careful with my diagnosis as I never had this problem.1 point

With decades of SAPS choppers spraying the rural areas, and in general the war on the plant, our local landraces have been decimated. I dont think the original DP is around anymore. Neither swazi for that matter. There has been European genetics influence on those populations for years. Lots of hybridization.1 point

Isolating a strain from what's effectively ''bagseed'' is a long term story with no guarantee of success. If the strain has been interbred with itself over a period of time your chances may improve. You will need space and time and lots of patience. Planting as many beans as you can manage properly, isolating good females and males depending on what your criteria is for the strain. Interbreeding them, then planting the resulting f1 beans and sifting through the offspring looking for keepers. It can take years on a small scale level to stabilize a strain.1 point

As a farmer I try and use common sense and only water my plants in the morning. I dont want the water to be sitting, damp while the big light ( sun ) is off. I prefer catching my veggies in the morning and greasing their roots with some nice sky juice.1 point

Well straight up... The rules weren't hard to follow. You gave warnings and still persons did not comply and that did suck... The competition needs to maybe have noob catagory and a "best newcomer" award, but needs to be more suited for experienced growers looking to challenge themselves. There are quite a few breeders on the site that I am sure will love to exhibit their genetics as the staple genetic for a grow off so maybe offer this to some of the local breeders... Give us an amount of seeds you need per grow off, and I'm sure guys will come to the party. Potentially a small buy in for serious contestants to compete for the main prizes , and consolation prizes for other entries that don't buy in.1 point
