Feminized Seeds Hermie Test - 14 strains, which are high risk; frequency; DM Reverse;

i'm growing fem. white queen, from amsterdam seeds...i'm finding next to no info on the strain, let alone how prone she is to herming...
i have some DM reverse, just in case, but would it also be good to spray them down preemptively? my plants are just now in their 6th day of 12/12, but vegged for 11 weeks, all showing pistils and staggered nodes...
in my head i thought maybe spraying them a few times around week 3, but would spraying as early as week 2 be better?

Hobbes get rid of the pro mix and replace it with oceans forest and worm castings also sounds like stress to me because all these female seeds are made with sts not hermied with a stamen.The more nitrogen the less likely for your plant to hermie.I have two greenhouse seed var. that I cant get to hermie even under light stress

ya iheard and am pretty dissapointed that i cant try ssd . i replaced it with purple diesel from high grade, only 60 CAD for ten i thought id give them a chance too and if it is real purple oregon thai in the mix its so worth it.


also had a question for you about peak. i like a sativa buzz right and i need a cheap-o outdoor plant so i was thinkin the two timewarp crosses blueberry and skunk. but im uncertain about the blueberry, think it will turn out shittay like yours? im already growing two skunk dominant strains and would perfer not to get another one but if i have to to get the best timewarp i can i will................so wat do u think mang?

get reg. seed dont do fem if you want to have more seed you could make your own. even sell them to your friends. you cant do this with fems to unstable they will herm .for this reason i think fems should be cheaper the regs. i could take regs and make more of that same strain with out haveing to reorder more seeds, but with fems i have to keep going back to the dealer. maybe one day they will think of this and change it around or even stop selling regular seeds all together male pollen will become exspensive just like in the dog or horse worlds the seed industry is assbackward in that respect. they charge you less and give you more, but charge you more and give you less i would rather have the ablity to make my own seeds for ever then to have to keep buying fems but thats just me. and i live in the usa,and i dont have acces to seed banks the way other countries do canada , amsterdam, UK so for them i guess it would be too time comesuming to have to remove males. but all i do is take 4 of my 10 seeds and veg then sex all need is 1 female then ,clone, clone, clone, then take that male you kept and pollenate one of the clones then you have seeds for life didnt even need to use the other 6 seeds. and all this for a fraction of the price of fem seed,
so you can kindof see why i say reg. seeds are a still, for where im siting its a still, i guess you could pollenate a fem but you would have to pollenate with a differant strain and this would make it too unstable, not to mention a new strain all together which could be good or bad most likely bad if you are crossing with bagseed. or you could be like that other guy who posted that he buys fem seeds every year theres nothing wrong with it at all you have to find whats best for you - where i live its not ez to come by good gens..............................

well said.. i got some fem seeds going right now.. and i wanna do my own breeding.. like u said gotta get some reg seeds...

"Hobbes get rid of the pro mix and replace it with oceans forest and worm castings also sounds like stress to me because all these female seeds are made with sts not hermied with a stamen.The more nitrogen the less likely for your plant to hermie.I have two greenhouse seed var. that I cant get to hermie even under light stress"

Thanks TM, that's a great tip. I've been wanting to run some Ocean Forest but it hasn't been sold in Canada except by mail order and it's expensive to ship in a dozen bags for each grow. But I'll order a couple of bags this weekend and mix them with some worm castings I bought a while back and threw in a box.

"all these female seeds are made with sts not hermied with a stamen."

What does "sts" mean?

"The more nitrogen the less likely for your plant to hermie."

Where did you read this? It's opposite of what I've been able to find.

"Nitrogen fertilizers masculinize the phenotype by stimulating the formation of male flowers. The proportion, number and degree of monoecious plants increases with increasing N, and the total N content is always higher in monoecious individuals than it is in females. (79)"

.

Hey CC

"but im uncertain about the blueberry, think it will turn out shittay like yours? im already growing two skunk dominant strains and would perfer not to get another one but if i have to to get the best timewarp i can i will"

Texada Timewarp is, I believe, a clone only strain from around Vancouver Island in BC, Canada. I'm not sure if anyone has back crossed to get an IBL or if it may have been breeding on the Islands for so long it can be considered a landrace strain. I've seen other breeders TT and it's always a cross unfortunately. I'd love to get some TT not crossed.

I have Peak's Blueberry and Skunk seeds in storage, I haven't grown either yet but from what I've read of their BB it should be sexually stable. Sagarmatha, Dutch Passion and DJ Shorts genetics is a good combination.

Crossing Peak BB with TT should improve the stability in the cross. The Skunk cross will probably be amazing and may not have dominate Skunk Characteristics. I think TT x BB will grow out fine, but email Peak and look through their testimonials.

I think your best course of action is to email Peak with your questions. They are very good (if a little slow) in helping out. Give them a link to this thread and this page number so they can find your questions quickly, ask them to post the answers here if possible. It'll be good for everyone to know and public injuries often get quick answers.

Feminizing your crop - In Depth

Feminizing: All You Ever Wanted to Know About Sexual Expression, and changing it


[This is from rexresearch.com, an excellent site for anything to do with growing cannabis.]


The sexual expression of cannabis is determined by its genetic makeup, and by its metabolic temper, which is regulated by the male enzyme andrase and the female enzyme gynase. Environmental conditions (light, nutrients, soil and water) may suppress the formation of the dominant enzyme, and allow the opposite sex to express itself partially (hermaphroditism) or completely (sex reversal). (71, 72)

[About this next paragraph: I thought that normal levels of N with lowered levels of K were ideal for producing fems in early veg...]


Nitrogen fertilizers masculinize the phenotype by stimulating the formation of male flowers. The proportion, number and degree of monoecious plants increases with increasing N, and the total N content is always higher in monoecious individuals than it is in females. (79)


Treatment of hempseed with ethylene gas will increase the resulting number of female plants by about 50%. Ethylene is produced by certain plants (i.e., bananas, cucumbers and melons), and these can be used to treat hempseed in a simple manner. About two weeks before you plan to sprout the seeds, place them in a paper bag or envelope and put that in a plastic bag with the peels of a ripening banana or cucumber. Replace the peels after a couple of days, and change the bags to prevent mold.



Hempseed can be feminized while they are forming on the plant. Fruit peels are spread around the area for two weeks before the plants enter the flowering phase. Remove the skins when the plants begin to flower. Otherwise, treatment with Etephon will accomplish the same effect.



When hempseed is treated with the female hormone estrogen, percentage of females that are produced will increase by about 10%. Dissolve a birth control pill in water and soak the seeds overnight in the solution. After the initial soaking, continue to treat the seeds by sprouting them on a paper towel soaked in the solution. (80)


A.I. Zhatov tested the effects of ethrel on hemp:
"Treatment of hemp plants with an aqueous solution of ethrel changed the ratio of male to female flowers. The greatest effect was observed when plants were treated during flowering of male flowers." (81)

Electricity also can change the sexual expression of cannabis; B.R. Lazarenko and I.B. Gorbatovskaya reported:

"Under the influence of the electrical current, the numerical proportions between hemp plants of different sexes was changed by comparison with the control to give an increase of female plants by 20-25%... The characteristics acquired by the plants in electrically treated soils are transmitted by inheritance to the third generation..." [emphasis added] (82)


Photoperiodism is a most useful tool with which to control the sexual expression of cannabis. For example, J. Limberk made a careful study of lighttime on the sexual index of hemp, and reported thus:
"Male plants usually flowered earlier than female. Female plants flowered only when the period of daylight was shorter than 14 hours; male plants flowered even when the day was longer than 14 hours. Reduction of light intensity in the first stages of plant development lead to increases of female plants by 4.3%. Intersexual plants (22-30% of the total) were present in conditions of 11-13 hours light per day. Grafting of plants did not change sex."



The probable future sex of a pre-floral hemp plant can be guessed at by calculating the Leaf-Mass Index (LMI): Count the points (3, 5, 7) on 3 leaves in the center of a cluster. Divide that number by 3 to determine the average number of points. Repeat the process several times, and figure that average also. Multiply the two averages to determine the LMI. A high LMI indicates that the plant will be female.



The phyllotaxy changes to alternate just before the onset of flowering. Then the sex of the plant can be determined by making a close examination of the upper nodes of the main stem. The onset of flowering is indicated by the appearance of undifferentiated primordial buds behind the stipules at the nodes of the petioles (along the stem at the base of branches). Within a few days they differentiate. The male pistils are flat or knobby with a curved shape and 5 open petals about 5 mm. long; they have a single tiny stalk. Overlapping vegetation often disguises their appearance.



The female develops pairs of flowers surrounded by pointed bracts of protective leaves that will enclose the seed. The female stigma usually appear as 2 fuzzy white hairs forming a "V" that protrudes from a bract. Resinous hairs (glandular trichromes) cover the calyx (2-6 mm long).



Gibberellin will inhibit the formation of flowers on cannabis, but sometimes it will otherwise cause the growth of fertile female flowers on genetically male plants. Silver nitrate or cobalt chloride causes masculinization of flowers of female hemp, possibly due to blockage of ethylene synthesis. High levels of N salts --- and long photoperiods --- have a masculinizing effect on hemp.(74-76)

"Dioecious hemp plants were grown to an age of 20 days in a day-length of 21-22 hours, then given an inductive treatment of ten 8-hour days to initiate flowering. After return to long days and during the period of differentiation of flower buds, a total of 0.5 gr lanolin paste containing 0.5% NapthaleneAcetic Acid (NAA) was applied to leaves at the 3rd and 4th nodes. In genetically male plants, female plants were subsequently formed in sites which would normally be occupied by males, a result which appears to be regulated by the level of native auxin in the vicinity of meristems during the period of differentiation of flower primordia. Secondary effect of auxin treatment were evident in an over-all reduction in intensity of heteroblastic development, the trend towards a reduction of leaf lobing and serration which normally accompanies plants passing through a period of flowering than in untreated controls."

Disclaimer: I do not vouch for the veracity of the information in this post.

I'm researching this info, very interesting. Any botanists on here who can confirm or deny this?

.

"The sex of the plant is determined by diffuse genetic markers (probably spread across the genome) not x and y chromosomes. This is why there is so much sexshifting with the Cannabis.

Doesnt a good 100-300 ppm GA3 spray give you localized (to the area of applicaiton) pollen production? You can get GA3 cheap from supergrow.biz

I dont believe it is possible to get 100% true fems, just 100% fem expression with a higher then normal percentage of true fems. This is because a true fem cant produce pollen and cannot be selfed. Fem seeds seem a waste to me, but if people want em. This is becasue Im pretty sure one could get consistantly 75% fem expressing plants from normal seed with a proper production schedule which includes ethylene and auxin treatments.

Also, if one wants to weed out fem expressing plants with male markers one might try giving male treatments to the seedlings and keeping the resulting female plants. They will most likely be heavy or true fems. I think BAP works good cause it tends to produce healthy, bushy plants but mostly male. "

STS is achemical agent that all breeders are using to reverse the sex of female plants.It can be puchaced at GH hydro.All breeders including soma are using these.Paradise seeds have ayou tube vidio showing aplant reversedat last years cup.It was of delahaze.Lucs gear is so stable it is unbelievable.I have grown opium twice from seed and now have been cloning a mother for six months without any hermie.I also understand you have alaskin ice,get it out of your grow now before you waist time and space with that bullshit.Too stretchy and no freakin BUZZ.I have GHS trainwreck ,opium, Mandala#1and hybrids i have bread myself.All are about done but this site wont let me post pic.Trainwreck in the 8th week with no hermie.

"STS is achemical agent that all breeders are using to reverse the sex of female plants.It can be puchaced at GH hydro."

Thanks MTM. I've heard of colidal(?) silver but never the other, and you can order it online. Imagine that. (Forest Gump reference)

I'm going to get a bottle of the stuff, fantastic.

"I also understand you have alaskin ice,get it out of your grow now before you waist time and space with that bullshit.Too stretchy and no freakin BUZZ."

Thanks again, you've saved me from a huge disappointment.

"I have GHS trainwreck ... Trainwreck in the 8th week with no hermie."

I'm thinking of growing Trainwreck as my next Fem, have you grown this strain before? Wondering about the potency, type of high. How many more weeks do you think until harvest?

.

The Trainwreck is super smoke,9out of 10 on potency.There are three phenos ,I am cloning off of the sativa phenoand it is mind blowing.The indica phenos are great too but I am a sativa lover.The indica pheno grows rock hard nugs and the sativa is somewhat purple.I wish I could upload pics but I am not the only one having trouble.Hey man you really have to try the Opium from paradise,any of lucs gear is stable and I guarantee you wont have any hermies.Opium has a sativa pheno and a indica pheno,I currently have both in mothers.I have harvested on run of GHS ice and wreck and there was no comparison ,the ice stretched beyond belief and harvested only 30 grams per plant.I fell for Arjan THC ploy on the ice just like you did.You wont be dissapointed with the wreck.If that ice is 23percent thc I will kiss Arjan and Francos ass.I dont know know why I cant upload pics or I could show you some buds .,that are going to finish next week.I also have several jars curing.Maybe in the next few days it will let me post pics so it will help you pick your favorite pheno.I gave you the wrong website for the STS ,I fond it in high times new products about 6 months ago.I am trying to find it but I have all weed mags for the last 10-years.Good luck with the wreck.PS I also was a pro mix fan but not anymore,oceans forest with castings just yield twice as much medication

The top bd is GHS trainwreck and the bottom picture is opium from my last grow ,my daughter puts all these fancy logos on my pics .I dont know how she does it.This is on my login name it still wont let me post pics

try making your pictures smaller

i have produced pollen with ionized silver and or giberellic acid both methods can work if done propely. i am aware of the sts method also which is effective although sts is highly toxic and somewhat dangerous while ga and ionized silver are much safer to work with. in fact to purchase sts a government form is needed at least in the us.

"i am aware of the sts method also which is effective although sts is highly toxic and somewhat dangerous while ga and ionized silver are much safer to work with. in fact to purchase sts a government form is needed at least in the us."

I think I'll stick to late flower bananas.

.

ionized silver is safe and easy to make and works well on most strains otherwise ga is another relatively safe alternative. i have done the late flower method also at least with some strains and it works.

is this true i found this on here somewhere

i'm doubting it...seems like Phrenology for seeds to me. I could easily be wrong.

false seeds depending on strain come in all shapes and sizes that includes males and females.
