Dank

Sounds like a good project @CreX , strangely enough the first drop I have ready for the forum is Mystery Sativas x KushCookies F2. Haven't seen too many pheno's yet but the moms were tall and sweet. If you have a very specific profile in mind it might be worth ordering some breeding stock to find a suitable dad.

@CreX sound like u need the "Sherbert" pheno from the KushCookies F2's selection. What is strain is your plant? Smells like dank sherbert tastes like dank sherbert. Its the sweetest thing I got, will make some F1 crosses with it to drop for sure. I am waiting some Zkittlez regulars, from Californian breeders, not the seedcompany in Spain or Amsterdam, there will be a marriage between the Sherbert and Zkittlez at some point.

Hi @Stoukie , haven't had to deal with PM in a while, some friends had good results with just mixing a tablespoon of vinegar to about 1.5l of water. Here is the recipe I used when encountering problems. Compliments of Smokin Moose "Hydrogen peroxide is beneficial as an addition to nutrient feeding programs at all times. It feeds the good aerobic bacteria and kills the bad anaerobic bacteria. It also introduces radical oxygen atoms which oxidize elements, making them more available for the roots to assimilate. I apply 3% H2O2 at a rate of 30ml/gallon to the reservoir. The plants show no visible signs of stress afterwards, which indicates that it was not an excessive application. Sprouting Seeds: add 30ml 3% H2O2 to 1 pint of water. Soak the seeds overnight. Insecticide Spray: combine 250ml 3% H2O2 to 1 gallon spray mix. Fast growing container plants: add 30ml of 3% H2O2 to 1 gallon water. Hydroponics: apply 3% H2O2 at a rate of 30ml/gallon to the nutrient reservoir." Edit - The US gallon is used in the United States and is equal to exactly 231 cubic inches or 3.785411784 liters. The Imperial gallon or UK gallon is used in the United Kingdom and is equal to approximately 277.42 cubic inches. Its exact value is defined as 4.54609 liters. One imperial gallon is approximately 1.2 US gallons.

@CreX that sounds awesome, breeding Cannabis is really fun and really not that difficult. Biggest challenge is keeping pollen in the right area's so that the sensi can also get harvested! Awesome @highchome I was thinking to start dropping some testers after the comp. Stoked to see your guys interest! Feel free to drop questions start threads in the forum section. I am always learning and experimenting. The future for breeding Cannabis is surely a bright one, will hopefully contribute to those future seeds you want to breed.

@PsyCLown IPM stands for Integrated Pest Management. Here is a nice source if you would like to read up more about it. https://www.grownrogue.com/cannabis-industrys-pest-control-secret-integrated-pest-management-part-1/

Lekker man! Having a nice IPM regiment during veg times really helps a lot I find. Everything wants that GOOD WEED, peeples, sheep, dogs, cattle, flies, fungus, ALLES!

About the yellowing of the leaves, it is quite normal later in flowering, especially if feeding regiment is stopped and flush started. The plants use resources stored in the leaves to finish up production, its a nice way to know that there is not to much N left in the mix and the plant is finishing up and doing its thing. Sorry about the PM, sure you will salvage some good product there, seems like the guys know how to treat this situation, just follow the advice above, should be sweet. Try to get the PM sorted out if possible, good luck @LukeS

@Pat999 @Stoukie I have a horticultural friend (not Cannabis) that mentioned to me the other day he uses cinnamon to control PM organically, I haven't tried yet. The usual H202 mix + some diluted vinegar also does the trick for me. Glad your are winning that battle man! If all else fails I defol like a mofo! Not trying to give advice just been meaning to mention this to you guys about the PM, especially with outdoor season coming sooooon!

The seedlings should bounce back fine, I would be careful of over watering with that medium, a technique i like is to simply feel the weight of the pot after you watered, compared to when it is a bit more dried out. When you transplant them into bigger pots at a later stage you could consider adding some perlite (if its available) into the mix, you can add anything from 30% to 50% perlite and be ok. This will make your mix a lot more aerated, will dry out quicker and plants roots will grow a lot faster. I also notice quite a bit of bark in your soil, while it is not the worst thing it the soil, it does require Nitrogen to break down, plants could get a bit short of N as they grow. After it breaks down it will start to release the N back into the soil. Does wood mulch deplete the soil of nitrogen? ... A: The nitrogen is not actuallydepleted, it's temporarily tied up. This can happen when organic materials low innitrogen, such as shredded wood chips or pine bark, are incorporated into the soil. - source nola.com/homegarden/2014/03/does_wood_mulch_deplete_the_so.html

The idea behind breeders sending out tester seeds to forum members is not a new one, it is how I got started getting some decent genetics back in the day, on International forums. Breeders send out free tester seeds of their breeding to get a better understanding of the results. The more plants we as breeders can see get grown out, the better we can understand our strains and get valuable feedback from community members. For the early days I think it could work like this: Breeders can let me know about any potential seed drops that they are planning, this is just a formality, after this I will give you the thumbs up to post about your "new drop" of seeds, post will then get stickied here until all available testers are sent out. The breeder agrees to send the beans free of charge to the tester, the breeder can pay for courier or arrange with the tester to pay the shipping fees, whichever way they decide. The reason for this being that we do not sell any Cannabis seeds here in the group, for now at least, until laws are in place. The tester agrees to do a grow diary here on the 420SA forum under the https://www.420sa.co.za/index.php?/forum/92-local-genetics/ section in the main forum. This will help showcase the breeders work grown by different individuals using different techniques of growing. Some testers might decide to just take the seeds and not bother with doing a diary, if this is the case, breeders can decide whether or not to send them free tester seeds again. Diaries do not have to be updated every week, but a start to finish grow with at least all growth phases. Testers that keep their diaries updated more regularly (like once a week or more) will be favored by the breeders. THE BREEDERS RESERVE THE RIGHT TO DECIDE WHO THEY SEND SEEDS TOO. That is the final rule set to ensure nobody tries to exploit breeders here on the 420SA forum. If a breeder is not sending you tester seeds, consider becoming a real part of the community and I am sure your luck will change. Keep breeding and growing 420SA! PS - Any ideas, advice or potential problems feel free to discuss it here on this thread. Ready to start rolling out some testers slowly slowly. Also running this past you @420SA , just jotted down what I was thinking, will update and edit as necessary.

Very cool @420SA looks great! DIY for the win ekse!

Just to clarify I meant purple in the veins of the leaves, not so much the stems.

@Slartibarfast she is looking nice! Is this auto the exact same strain as the previous grow? Also have you been feeding her, could be that she is a heavy feeder/not a heavy feeder, or perhaps soil is a just bit different, there are so many variables in a grow. Even seeds from the same strains do not usually perform exactly the same as their siblings. I see there is purple down the veins of some of the leaves, if this is not a signature of the strain I would guess your soil has a bit too many metals, perhaps Iron, or the PH is just such that the metals are being absorbed by the plant. (This is just a maybe, rarely happens)

Hey guys and gals, are we running out of steam for donations? The minimum donation is only R10, just thought I would mention it. Thanks again for this platform @420SA truly LEGENDARY STATUS!

Here is some decent content about breeding, some cultivation information as well.

Hi @growopz , growing outside I usually defoliate quite a bit of the older fan leaves as they lose some luster, depending on the strain I could remove up to 60%-70% of the bottom 2/3 (fan leaves) by harvest time. Outdoors this helps a lot with the PM, and getting those popcorn nuggies to get phat. Indoors I usually go bare bottom (no leaves or growth) below the screen, then some defoliation through flowering, mostly to remove yellowing fans, or to get light on a shaded bud. Side lighting should increase the lumens and production I would say, ofc considering the direct heat on the plants. I am a LED noob so I am not sure how close or far lights need to be, growers in Canada love using side lighting (sommer HPS) in their massive grow rooms. Here is a excerpt from 420Magazine posted by Weaselcracker , he is quite experienced with it. "As for defoliation- I think first we would have to define it. The term could cover a pretty large range of practices. Usually I think of it as -major stripping of leaves to ‘increase yield’. Some people go around constantly pulling off fan leaves Almost all people do some amount of thinning and trimming. In general sativas seem to dislike getting tortured in flower. Sometimes that’s a good thing when you’re trying to slow them down. Most people doing a lot of defoliation and getting away with it seem to be doing it to heavy indica strains."

Yip you have those correct, the mycorrihizal fungi is common practice when transplanting these days, I think the fungi would also help minimize the stress, as well as you mentioned supply nutrients and what is needed to the plant to assist recovery. Using EM1 and the Myco is a good practice to ensure you have a diverse beneficial microbial ecosystem in your soil. Happy soil happy plants.

Very cool experiment @Stoukie I see online the auto's do well with the LST training, not many topping their plants, love a bit of good ol weed tinkering! One could also coordinate the topping of the plant with prior dose of MycoRoot (or similar) as well as EM1 if it is available, this could minimize a lot of the shock and really assist in recovery. Cannabis plants take quite a bit of mutilation in nature (ofc sometimes the plant doesn't survive), bouncing back and growing stronger than before is not uncommon. Recent findings also show that LST and certain techniques like some defoliation, etc can actually increase the terpenes and possibly resin production. These tests were most likely done on photo strains. Its only natural that these tests get done on autos!

Kilimanjaro x DP I saw this available at World of Seeds https://www.cannabis-seeds-bank.co.uk/world-of-seeds-landraces-kilimanjaro/prod_2780.html feminized and regular. Not sure if this is the one that clocks in at 26%, but the only one I found for sale, only did a quick search though. I usually try to keep the original moms vegging (and sometimes dads), seeds that arrive from overseas (for a few runs at least). That way you can always create a inbred line, DP line, or whichever you wish. The main benefit is that strong mom / dad can be identified and you can always backcross to stabilize, or make new hybrids.

@Kgrows it is a good idea for us hobby breeders to buy in some genetics every year if possible, the truth about starting from pure landraces (not Afghanica cultivars that had human intervention) the growers in Amsterdam start growing out 1000 plants for their first selection of parents, naturally for a hobby breeder this is a bit difficult. Strain hunting is awesome tho, I am not sure if you have seen the series "Strain Hunters", but when they go to Swaziland they find a lot of hybrids before eventually finding the Swazi Gold sativa. Personally I haven't been to Swaziland so I cannot say for sure how rare Swazi Gold has become. Strain hunting should partly be to preserve the genetics as well as finding new exciting crosses. Usually when you make a hybrid from two distant strains, some interesting pheno's should occur. If you do decide to get some Kilimanjaro beans, I have a few mystery sativa's that is crossed with my KushCookies F2. I can send you out some tester beans of these (if you were keen ofc), providing you are willing to do some pheno hunting as I have not grown out too many of these mystery sativa crosses. The few that we did see this year were quite interesting plants. I would pick a Kilimanjaro male for them, but would have to be a future project for me personally.

@Kgrows we have Durban Poison that adds quite a bit of THCV into the mix, providing it is the genuine strain, if it does not have to be South African, but African, take a look at the strain Kilimanjaro, reportedly measures 26% consistently on flowers, pretty good for a landrace strain. Locals call it the elephant killer lol. I have never grown it, but sure looking forward to it one day. If i was doing a African breeding project I would play with Kilimanjaro and some of our ZA strains, see what happens. The beauty of landrace strains is their genetic makeup, thousands of years of natural selection (with minimum help from human breeders) provides very homogeneous genes for a particular area/ecosystem. Kilimanjaro Named for the tallest peak in Africa, this sativa sets the bar quite high. Originating in Tanzania, this landrace strain became incredibly popular in Europe before taking off in North America. (side note: a “landrace strain” is a strain of cannabis that is indigenous, original, or otherwise naturally occurring. Landrace strains create the body of strains that hybrids come from.) It packs a wallop with at least 26 percent THC on almost all flowers tested and is consistently one of the most potent strains available in Canada. The flavors are bright, fresh, and citrusy, and the high is a classic, stimulating, energetic burst of creativity, just like most sativas. It will have you blessing the rains down in Africa.

Feeling blessed

High THC Content Strains There is some HulkBerry from RQS in my recent order, apparently should test quite high, not as high as the "Glue Strains" I would imagine. In the past I have had some White Russian plants that were super potent, no idea about what the thc levels were. I saw on Wikileaf (not sure about these tests) that Nothern Lights registered 35% thc. Interestingly the Chocolope in the growoffs was polinated by a NL dad. I think I read that somewhere on the forum, not 100% sure tho. What do you guys think about High THC Strain breeding, any new strains or even landrace strains tipping the scales? Just cross one high thc strain with another and select for even higher thc?

Damn baie mooi!! Jis im jealous bro, the neatness is also next level, making me feel a bit slordig jong! Nice to see that build, never seen a similar one, you should patent it! Curious how many lumens you will be pumping out there, going to be staunch!
