breeding

[wutwut]

can someone write me an short list about breeding? it's my first time trying to make new seeds with selected parents.


what kind of males not gonna looking for? how about lights and temperature? is it just better to sex only couple of branches in the grow tent which plants inside of that are going to be medicine?

other opinion is to dust two clones in a closet with 40w/125w cfl.

i would have to ask what your goals are, and what kind of seeds are you looking to make. without getting too specific (which you need to do lol), males that are slow to finish flowering, or have low flower production would probably be something to select away from.

there are S1s, R1s, F1s, and so on. you can feminize, you can rodelize, you can cross male to female, bx a female back to itself, and so on. its all based on selection, in one way or another.

lights and temp are no different from the ideal growing environment. you dont need to change if you are close to 75 F and 50 RH, and putting out a decent amount of light intensity and penetration. that being said, cfls arent going to cut it in any high yielding way. a closet is also not a great place to grow plants period. you need ventilation, and most closets do not have any.

do some real research on icmag, and wherever else you like. i would suggest you tighten up your grow game before you try to attempt any breeding, even if for personal use. just throwing some pollen on a female plant randomly is not breeding. its called chucking.

good luck!

I agree on some points with the poster above... but disagree on some others..

Yes you should have a goal or two but really it still is breeding.. it's super fun and rewarding, and as long as your honest with yourself and other people about your selection process and parents then no harm can really come( other than seeding your smoke) and you'll learn a lot and I find it personally rewarding!

First goal I would focus on is how many seeds would you want to make? A small plant can yield 100 seeds pretty easily... every hair can become a seed theoretically...if you wait till around day 25 of flower that's a lot of hairs, but at day 20 or so you'll get a lot and probably get bigger healthier seeds although a bit fewer..

Next is traits you are trying to isolate or add to the female... if you want to isolate choose a sibling male if available and try to select for similar growth rates leaf shape smell etc..in a partner , where as if you want to add bigger buds or thicker stalks you would look for plants with those traits, maybe from other lines even.

If you have a closet /cardboard box/totes whatever you can build a breeding chamber... in this you want no wind ideally and no air to escape...it will ruin your smoke crop like nothing if a fan is blowing that pollen anywhere! You can even cut branches of the male and flower them in cups of water like a cut flower over paper to collect the pollen, or just put a small male in with a few small clones under pretty low light even... they just need to live really... but healthier plant will make more bigger healthier seeds... still 4 or 5 clones flowered immediately in beer cups or yogurt tubes whatever with a male put in 7 or so days later will yield 100+ seeds even under a small amount of light... just lower light and temps mean less water... be wary of overwatering as the plants will die...

But yeah super easy and fun... just dont seed your weed by accident and say I didn't tell ya so..

If you do want to pollinate a plant and isolate the pollen to a branch or signal plant just use a bag to contain the pollen, leave for 24 hrs or so then wash the plant off with a sprayer or in the shower... it will kill the pollen that hasn't done its job...

Male selection is a bit more complicated than females. In females you can
evaluate the smoke right away.
You can't do this with men without some gender changing by some chemicals.


What you can do is watch their looks and take a sniff from a stem rub, which
gives hints of the terpene types and concentration of that phenotype. Compare
the smell of the stem to the desired females stem rub smell and you'll get an
idea if its the same or something different. You can also select for early or late
flowering in males. Don't select weak males, that's obvious.


You also can select different males and pollinate the females separatedly and
grow out the offspring and then evaluate. Thats how males are evaluated in the
end - in their offspring. There is also a thread about the gender changing hack
with ethephon. https://www.icmag.com/ic/showthread.php?t=99597

Whats an r1?

Litterally all the plant wants to do is reproduce, if you just plant seeds and grow them..providing they are regular m/f progeny they will make seeds and all you have to do is supply a constant environment typical to this species. It is also a particularly adaptable and robust species by nature, so one would struggle to not make seeds....breeding is improving a line, just make a bunch of seeds and grow them and repeat and over time the genetics will adapt or die.

an R1 is nomenclature for a female plant, reversed onto a different, unrelated female plant. where as an S1 is simply a female plant reversed onto itself, or hopefully a separate second clone of itself. or more if you are making bulk seeds.

if the original poster wants to go through generations of selection of large amounts of regular seed, in a closet with cfls, he or she has my blessings lol. sounds like slow torture for a beginner grower. im merely suggesting that he or she step up their growing skills and research more on their own, maybe grow out some headstash first before attempting something as time consuming as suggested.

Yeah, but making your own seeds is a really fun process. I agree it starts to be a huge time suck when you're trying to develop something, but you gotta start somewhere. And it's a different kind of reward pulling out hundreds of seeds that you made from a harvest. You can usually end up finding a keeper out of that first run pretty easily and just run that for a little bit while you get your bearings on what you want to do next.


Almost every plant I grow came from seeds I made through haphazard pollen chucking, and I regret none of it. As time has gone on, I've gotten a better idea of where I want my crosses to go, and will be starting my f2 hunts on one of those lines very soon. Also in a very small space.

Someone shared this genetics explanation a while back. It gives a pretty good rundown and should answer allot of your questions. As an addendum, the time frame of landrace genetics being mixed up has created so many mutts x mutts that predictable outcomes are somewhat of a long shot. Practices of 'pheno hunting' and 'clone only strains' prove this to be true.

nice find, and agreed on the state of genetics nowadays. too many pollen chucks have introduced a large amount of muddied genetics to the scene imo.

when i was a young lad on the sales floor, we had varieties that would sound so utterly boring nowadays, NL, four way, sweettooth, (old) ak47, chem in its infancy, g13..... so many good varieties with individual expressions. nowadays reading these lineages is a full on research project.

I pick the male that displays the best vigor, shows balls the fastest, has the best structure as far as node spacing and leaf size that I'm looking for, and ideally has a strong smell
