yes you can stress the fem to produce male sacs but the seeds you get from the self pollinates plant will all be hermie seeds, now if the pollen from the herm pollenates another plant that is female those seeds from the other plant will be fem seeds. but yeah the seeds a self pollinated plants gives will give you all hermie seeds. you catch my drift?

I hear you bro i know exactly what you mean. TY for info it makes a diff in my breeding program. Look out Ihave some kickass breedings going on. Much Mahalos
that means thank you in hawaiian

no problem dude, thats what this place is here for to learn. just glad i could help you out.

no that is incorrect if the female you choose to reverse is a stable female and does not herm under stress it is a good candidate for reversal with silver or ga3. if it was stable prior to being selfed it will be stable as an s-1. herm tendencies are genetic regarding either s-1fems or normal females.

I agree with bicycle racer. If you have stable genetics to begin with and are using silver or g-acid to block the hormone that creates females, you'll end up with a male plant that doesn't carry the male sex chromosome and the resulting off spring should be all female.

Unless your using a strain that is prone to hermi and really I haven't read a lot of reports from breeders who have used hermi strains to make S1's so that part at least is just my speculation..

I'd probably be a little more concerned with loss of vigor depending on the strain.

well if you look at the question the dudes asks he says "stress" a female to get seeds...... nothing at all about using silver....so yeah i am correct buddy

again this persons question was about "STRESSING" a fem seed into making more fem seeds. nothing about S1 or using silver. the strain here is not even listed so any reports of hermies are irrlevent. so again i am correct. if you stress a fem female, the seed you will get from that "stressed out" plant will be hermie. :boogie:

I dont know, i might be wrong here but i always thought a seed can't be hermie but she can carry the hermie trait in her genetic pool, any thougts?

yeah plus not having your grow room dailed in can bring out the hermie trait in fem plants. also light leaks during flowering... anything that can stress the plant can bring a hermie trait out of the gene pool

Let me see if I understand this right if I use silver or ga3
to produce male pollen on the feminized plant that I will more then likely produce viable feminised seeds without hermie problems.

yes that is correct yo. not by stressing them

I'm under the impression that Colloidal Silver and such methods are also considered "environmental stress".

Here's a lil blurb from Marijuana Botany by Robert C Clarke:


i) Sex -
Attempts to breed offspring of only one sexual type have led to more misunderstanding than any other
facet of Cannabis genetics. The discoveries of McPhee (1925) and Schaffner (1928) showed that pure
sexual type and hermaphrodite conditions are inherited and that the percentage of sexual types could be
altered by crossing with certain hermaphrodites. Since then it has generally been assumed by researchers
and breeders that a cross be- tween ANY unselected hermaphrodite plant and a pistillate seed-parent
should result in a population of all pistillate offspring. This is not the case. In most cases, the offspring
of hermaphrodite parents tend toward hermaphrodism, which is largely unfavorable for the production
of Cannabis other than fiber hemp. This is not to say that there is no tendency for hermaphrodite crosses
to alter sex ratios in the offspring. The accidental release of some pollen fro predominantly pistillate
hermaphrodites, along with the complete eradication of nearly every staminate and stami- nate
hermaphrodite plant may have led to a shift in sexual ratio in domestic populations of sinsemilla drug
Cannabis. It is commonly observed that these strains tend toward 60% to 80% pistillate plants and a few
pistillate hermaph- rodites are not uncommon in these populations.
However, a cross can be made which will produce nearly all pistillate or staminate individuals. If the
proper pistillate hermaphrodite plant is selected as the pollen- parent and a pure pistillate plant is
selected as the seed- parent it is possible to produce an F1, and subsequent generations, of nearly all
pistillate offspring. The proper pistillate hermaphrodite pollen-parent is one which has grown as a pure
pistillate plant and at the end of the sea- son, or under artificial environmental stress, begins to develop a
very few staminate flowers. If pollen from these few staminate flowers forming on a pistillate plant is
applied to a pure pistillate seed parent, the resulting F1 generation should be almost all pistillate with
only a few pistillate hermaphrodites. This will also be the case if the selected pistillate hermaphrodite
pollen source is selfed and bears its own seeds. Remember that a selfed hermaphrodite gives rise to more
hermaphrodites, but a selfed pistillate plant that has given rise to a limited number of staminate flowers
in response to environmental stresses should give rise to nearly all pistillate offspring. The F1 offspring
may have a slight tendency to produce a few staminate flowers under further environmental stress and
these are used to produce F2 seed. A monoecious strain produces 95+% plants with many pistillate and
staminate flowers, but a dioecious strain produces 95+% pure pistillate or staminate plants. A plant from
a dioecious strain with a few inter- sexual flowers is a pistillate or staminate hermaphrodite. Therefore,
the difference between monoecism and her- maphrodism is one of degree, determined by genetics and
environment.
Crosses may also be performed to produce nearly all staminate offspring. This is accomplished by
crossing a pure staminate plant with a staminate plant that has pro- duced a few pistillate flowers due to
environmental stress, or selfing the latter plant. It is readily apparent that in the wild this is not a likely
possibility. Very few staminate plants live long enough to produce pistillate flowers, and when this does
happen the number of seeds produced is limited to the few pistillate flowers that occur. In the case of a
pistillate hermaphrodite, it may produce only a few staminate flowers, but each of these may produce
thou- sands of pollen grains, any one of which may fertilize one of the plentiful pistillate flowers,
producing a seed. This is another reason that natural Cannabis populations tend toward predominantly
pistillate and pistillate hermaphro- dite plants. Artificial hermaphrodites can be produced by hormone
sprays, mutilation, and altered light cycles. These should prove most useful for fixing traits and sexual
type.

word...I think making feminized gear is evolved into an art form.
I agree with the hermaphrodite tendencies in a strain carrying over. That would suggest, in making S1's, that we stay away from strains that have any herm tendencies. The Marijuana Botany excerpts would further suggest that end of flowering would be best for forcing pollen from a donor female. This, I think, is where experience with breeding comes into play, as a female gets older she is less fertile. So I think there is a certain point in flowering that is optimal to force pollen.
I'm not convinced there is a difference between the seeds from the pure female recipient as the seeds from the female that was forced to reverse. It would take a batch of each to prove it to myself. So I'll remain constant on my thinking that there is no difference between the two until proven to me otherwise. So that is to say, S1's will only be hermaphrodites if their parentage carries this trait, not from being forced.:evilgrin0013:

So if i had a feminized plant and it got stressed from say a light leak and hermied and pollinated a female plant in my garden the seeds from that plant are no good?

again no. either the plant is stable or its unstable plants that are genetically stable females will tolerate stress and light leaks without herming while another strain right next to it which is herm prone will show problems right away. the plants that dont herm under bad conditions are good candidates for stable s-1's

yes you can stress the fem to produce male sacs but the seeds you get from the self pollinates plant will all be hermie seeds, now if the pollen from the herm pollenates another plant that is female those seeds from the other plant will be fem seeds. but yeah the seeds a self pollinated plants gives will give you all hermie seeds. you catch my drift?

also if you use herm pollen on a different female even a stable one you will still get some herm seeds. as you used pollen from a herm plant therefore introducing that trait to the seeds produced. saying herm pollen used on another different female will produce fem seeds is wrong.

use of silver binds copper inhibiting ethylene production in nature this never happens. so it is not something the plant genetically has a built in stress response for. ethylene inhibition is the only proper way to make fem seeds that im aware of i have made many fems this way and have yet to see any herm problems of any kind with the resulting seeds. one thing i dont do is make seeds on the reversed plant i only collect the fem pollen and then apply it to another clone of the same strain which has not been sprayed with silver at all and is a normal female.

stressed moms make stressed babies, simple as that. bicycle racer is on point with what he is talkin about that dude sounds like a mad scientist, props yo! clones are soooooo much easier than seeds, but looks like youre already into flower so that wont work. or you may just want some seeds, i dont know! i only use seeds last resort im starting some right now actually, trying to get some new genetics in this barren wasteland of a state i live in. anyway good luck!
