    what's funny, the plant i did right before, had a similiar problem, all i did was do a soil topping and kept it waters, which is what i did with that one, plus trimmed the damaged parts off of it. The next day...bam....hermied.....

    since then i have already re-amended the soil with iron, and also added more bone meal......which i need to keep up for later reference....

    Any chance you may be overwatering some. The thick ribs on the upper leaves and early yellowing points to that.

    Everything i can find in a one min search says
    Hermaphrodites are caused by genetics or stress

    Not to be confused with a bisexual flower (nanner) which is mostly stress related.


    So are these guys wrong? Any links to real science ?

    Hermaphrodites are not the same as a reversed plant. They grow male and female parts together and it is genetic. And rare just like humans.

    Reversed plants show some male parts randomly and are caused by stress or phenotypical tendencies.

    Best marijuana info in more of a textbook form is Clark’s Marijuana Botany.

    It’s in this free book list.

    You havent understood my explanation so the confusion still exists.

    There is no correlations to breeding hermies or stabalizing them.

    The thought reason for hermies is that it exsisted way before we turned up and has always existed hence why we can NEVER breed it in or out.

    The fact the plant can do this is because in the bad years the shorter the distance pollen has to travel the more chance of survival of species.

    I write this so we can dismiss your assumptions on the subject, these assumptions of stabalizing and breeding hermie free strains are not in line with current 21st century biology or all the evidence on the subject.

    But reversing a plant shows just how easy a herm system might work as in the plant has all the genetics to make male and female parts but not the genetics to make male seed from female reversal.

    It still misses the male chromosome.

    I agree with the mode of action you are saying but you sure can breed out hermies for the most part by crossing the plants with the best resistance.

    If it couldn’t be done we would all have seeded rooms.

    I find it a slap in the face to write that redundant stuff after everything i have presented.

    Mine is just the leading scientific theory when scientists tried to find the cause of herms in weed.

    They couldnt with conventional technology but ruled a lot out and left this theory plus a statement that it is shit hard to find or understand in this plants complex genetics and protein systems.

    No slap at all man

    I just want links so i can read at my own leisure is all lol

    These books state that it is hardwired and from stress. Easy conclusion to agree with when youve witnessex it first hand as a grower.

    Not the book I suggested. You should read it.

    Also ed Rosenthal explains it pretty well in his old book.

    Most of the info being argued about has been tested and is correct in Ed’s old book. Even uv and far red light.

    Very little new info is actually out there. The old reports are just off the radar. New people want the credit in the new industry.

    What links???

    The small amount of science turned up nothing except they need a bigger microscope which as of yet hasnt been invented.

    Taken six years to even find a scientific analysis of the subject, it would be shit hard to get this info again.

    Mainly they found more complexities and studied them, this plant dont get much funding for hermie issues.

    Yes they were correct on lots of stuff, these sites complicate everything though.

    Just growing and observing answers many questions without even needing to resort to the science.

    Those books have both. Grow observation and science.

    Yes very scientifically correct on most things, they were the pioneeers before us and the whole industry took off. Most were keen to make money, assuming youll find them in legal states behind many companies now.

    This is what I was getting at. I think op is going a bit too far with it. The genes determine how sensitive the plant is to hermaphroditism weather every plant is capable or not.

    Here's one for you MichiganMedGrower

    Sounds like someone's been reading from this a bit lol.

    Natural Hermaphrodites



    Some hermaphrodites seem to be genetically determined (protogenous). That is, they naturally form flowers of both sexes given normal growing conditions. Possibly genes carried on the autosomes (the chromosomes other than the sex chromosomes) modify the normal sexual expression. Monoecious varieties have been developed by hemp breeders in order to ensure uniform harvests.



    It is also possible that these particular are polyploid, which means they have more than the usual two sets of chromosomes. This kind of hermaphrodite may have XXY (triploid), or XXYY or XXXY (tetraploid) sex chromosomes. However, no naturally occurring polyploids have ever been verified (by observation of the chromosomes) in any population of Cannabis. Polyploids have been induced in Cannabis by using mutagens, such as the alkaloid colchicine.



    Whatever then genetic explanation may be, one or more of these natural hermaphrodites may randomly appear in any garden. They are sometimes faster-maturing, have larger leaves, and are larger in overall size than their unisexual siblings. They usually form flowers of both sexes uniformly in time and distribution, and in some unusual patterns. For example, from Mexican seed, we have seen a plant on which separate flowering cluster consisted of both female and male flowers: and upper section of female flowers had upraised stigmas, and a lower section of male flowers dangled beneath the female flowers. In other plants from Mexican seed, the growing tips throughout the plant have female flowers; male flowers sprout from the leaf axils along the main stem and branches. Plants from "Thai" seed sometimes form male and female flowers on separate branches. Branches with female flowers tend to predominate, but branches having mostly male flowers are located throughout the plant.

    Given that genetic anomalies exist like chimeras and shit, it's not 100 percent on anything yet I'd say.

    I never saw that before.

    And I see in your next post about the Thai and Mexican having known bisexual growth patterns.

    I have only seen hybrids grown outdoors but I understand hermaphrodites were common in the land race plants and we have bred the trait out best we could.

    And the debate continues lol. I find this all very interesting but my own observations lean towards the fact that throwing "seeds" has been solely caused by stress. Not sure if the plants that did throw seeds were predisposed or not, but without stress they produced seed free buds for 3 runs of clone from clone. Once they were moved outdoors (clones) they produced a few viable seeds, mind you the one seed I did grow out produced a plant with completely different characteristics than the original. Should have tried to keep it as it was one tall 4' single bud, great sog plant lol. Back in the days of the larger field grows we had to stay vigilant to cull the odd plant that threw balls or the whole grow was compromised, hence the 45 gallon drum for bubble hash lol.
