Would giving a plant one hour dark in the middle of the light period everyday work the same? If you grow outdoors its a lot easier this way round! Or do outdoor growers have to use chemz to make femz?

mate one hour of light in the middle of the dark period works inside aswell as outside i mean why use chemicals when it so easy to give one hour light in the middle of the dark period works great with no chance of any chemical nasties going on plus its also alot cheaper than chemicals

Not very stealthy to try and give outdoor plants extra light during the night though eh.

I wouldn't want to grow fem seeds that will hermie due to light torture.

Covering your outdoor guerrilla plant up during the day for an hour is possible.

Giving your outdoor guerrilla plant light during the night isnt possible.


So my Q is does dark during the light cycle stress the plant enough to hermie?


As for chemical nasties, your spray it on to produce femmed seeds. you dont have to smoke that bud, it wont be sensi after all. just grow some plants for next yers seeds.

the seeds produced arn't light tortured just the father plant is

my first ever grow produced shed loads of feminized blueberry seeds which I still have loads left, but is nice strain so I am happy.

as for dark during the day im not sure worth ago though yes you cant give a gurilla grown plant one hour of light at night but you just said an outdoor plant and an out door plant can be brought in during the night if its in your garden
ps you only have to light stress the father plant into being a hermaphrodite from a normal female plant. then use the pollen to seed yor outdoor plants o need to strees every plant out just one ordinary female plant must be turned hermie this will produce enough pollen to make many many seeds

Ahh thanks green dreemer, hadnt thought of that, Grow 1 plant indoors and stress it then collect pollen for lots of guerrila ladies, that makes sense.

glad you now understand

Was that deliberate speed?Thats what I am feminising,Dutch Passion Blueberry,how many seeds you get from a feminised lady if it was accidental?

No mate not deliberate as it was my first grow I light stressed them, but the weed was excellent smoke and the seeds their was shed loads.

any issues back crossing with itself. using the pollen on the stressed female

no that is called selfing a plant hvent had any probs that is how big budda's g bomb was developed from a clone only strain the g

same as, had skunk11 feminised spew a hundred or so, binned them all as couldnt work out if seeds grown would be hermi's, im assuming so, was not sure as was not going to light leak the seeds that i got from the feminised plant, still baffled today

mate those seeds were femmed you should not have thrown them away and iv never had a hermie of any of the seeds i have had myself getting them this way or any of the femmed seeds that i have brought and hope my luck continues as iv heard alot of people have had hermies of femmed seeds
i have had alot more hermies of regulare seeds than iv had from femms

bummer, will remember next time,

I've read the same about using the pollen from female plants which send out a few male flowers.

People can be very against using such pollen and i think it depends.

There's a thing sometimes occurs which isn't like bad genetic hermaphroditism, a couple of male flowers low down a plant after budset and no more than that.

I have 1 Himalayan Gold right now which sent 2 male flowers out and the pollen's in my fridge and i will use it, revegging both HG's i last grew and stressing the one which didn't give 2 male pods so i get more diversity in the seeds, (2 very different pheno's i should add.).

Plants doing this are just being naturally dioecian in a very casual and minimal way and those who know and grown for years well before i started aren't fussed, so i was and am fine about this and i expect nice femmed seeds just as stable as if i intentionally stress hermied.

But then, there's plants which will break into tons of male flowes all over the plant where buds set without intentional stressing.

These are considered, i consider, genetically corrupted and will most likely Not give femmed seeds but hermaphroditic and all offspring will be as bad as the parent so never give decent bud.

So these need to be culled, not persevered with.

A few odd male pods early on after budset is natural enough in plenty of strains, apparently, so i'd encourage anybody to take advantage and get free femmed seeds, cross as well for good vigourous variety etc.

But genetic hermies are not the same, if tons of male flowers express on a female and you didn't cause it on purpose you'd just be wasting your time imho.

Paxus.

So i wonder why no one just did it with a cheese clone

Interesting.

I had a Mandala #1 that I flowered a little longer than the others and after the chop I noticed one male flower pod very low down on one of the buds and I had like 1 beautiful, mature seed below that.
I assumed it would be hermie but stuck it in with some others I was growing in a tiny pot to see what would happen for myself. It is 5 weeks into flowering now and no signs of any male flowers as yet.. smells the same, though has slightly weird looking pistils ...straighter , more stuck together and less wispy than the original

how do you collect such a small amount

Will give collodial silver and GA a go next month to see how it will work out!
Any ideas on how many ppm (parts per million) your collodial silver should have best?
Going to try out 500 ppm first! You will need a collodial silver generator to make sure to get real collodial silver,
because otherwise you just end up with a silver ionic solution, ain't you?
We will keep you uptodate!

SGBs

Does anyone know anything about PP Seedbank - I can't seem to find any info about them?

Its the same guy who is doing work on HR's "Black-rose" chillie,its a UK based seedbank doing their research abroad.

you can order GA3 from ebay and some other uk gardening specialists too!

sgb the ppm is around 15 ppm for cs il be on this thread in more detail in a week as im still using my ps3 to surf an its hard to type anything but will have comp back by then

Silver thiosulphate isn't something in itself that can be sourced. You have to source silver nitrate and sodium thiosulphate and then mix them in water to make silver thiosulphate solution. Silver nitrate and sodium thiosulphate are both used as photography chemicals.

what a read!!

using the light stress method sounds like the easiest option for me, would this be possible to only stress 1 bud or so with a torch rather than stress the whole plant?

also im in wk 3 of flwrn now, would it be a bit early to start stressin em out?

id hate to upset them prematurly , even thou i plan to stress the jeebus outta a bud or 2 if it works like that?

ef.

how many nights of light stress? a week or until the male flowers jump out?

You could stress one branch or 2 but dont know how you would completely isolate the rest off the plant. week 3 of flower is good as you dont want to start to late as the buds will be past there best later on especially on your mother plant.

how many night could be anything maybe around a week at a total guess

makes sense.

im thinking a led torch shone thru a tube with a branch in .

but wud that be enough Watts?

praps itd need to be stronger than that, i think im gonna grab one now, its been int dark for 51/2 hrs now.

LED it is. and ill try n remember to do it for a week.

ef

dont matter mate about watts if they can herm from a light crack in the door

well, that was easy enough for the first night. if i can keep it up til i see balls ill be chuffed.

just so u know, im using a 9 bulb LED torch. are they still callled bulbs?

as u can see in the pic above, the kitchen roll tube goes over the bud to be tortured into submission.

and the torch hangs into the top of the tube. with tissue at the bottom of the tube stopping any escaping light.

im surprised at how hot that lil torch got in an hour.

ok, more learning to be done.

ef

ok, the light went on at 7am.

and i got to thinking, if the light stress affects them at night, would a 'dark stress' have an equal effect?

well, i dunno, but im gonna do it anyway, see if i can uberforce some balls out.

heres some images.

ef

dark stress would work. no point on leaving leds on 24/7 as the branch would veg not stress. you need to go in like in for a random hour in the dark cycle and vice versa another way to stress them if over flower them by extra weeks like 14 for an 8 week strain but you need younger buds to cross the pollen with

Wow! what a very interesting post this has taught me alot bloody brilliant i tell thee

¿Where'd you get those 85W CFLs from, eurasian_farmer?

easy.

so the 2nd day of stress factor... they've had now 2 interrupted nights and one interrupted day period.

so it goes, lights out+5hrs(1 hr stress of light)
and then, lights on+6hrs(1hr stress of dark)

hopefully they wont know what to do except, whippin the sack out.

no pics from last night as cam was unavailable. but heres a shot from 10 minutes ago.

scribb, my local hardware guy has em in 'blue' but the 'red' ones have to be ordered by the dozen.
so as yet i have none of the reds.

ef

the subject bud is the murky lookin one in the leftcentre foreground, as of yet, balls=0
i was gonna add a pic of the cfl box, but its not around, musta dashed it out.

bahahahahahhaah, what a great choice of words mate hahahahahahahhaha ::

sorry.

rubber band is round the bud im puttin thru a world of torment.


ef

almost 2 weeks of nightly interuptions and still no balls...wtf's..



ef

To be honest, that's a good thing. You don't want to make fem seeds from a plant that was easy to hermie. In fact, if you want the most stable fem seeds, that are the least likely to hermie in the future, you should stress all of the plants to weed out all of the hermie prone plants. You want to find the female that is the most resistant to sex reversal under stress. Then give it silver to reverse it. The seeds should be much more gender stable.

2 weeks is nothing but in my opinion you started late but you still have options soma over flowers his strain say an 8 weeker 11 weeks which causes his plants to go into survival mode and kick out sacks if it was me i would harvest a couple off buds for the stash now and then if ready and keep a few on there to over ripe as you need only a couple of sacks for alot of seeds.
Also what is with the green light if your using green it wont stress your plant in theory

High all just thought id give an update as was gifted some 3 femmed shortryder seeds from nirvana as the others did not auto Cut a long long short these have preflowered after a couple of weeks in 3l pots so one had its first aplication of cs today

cheers all, got the silver on its way!

ur right i did start late, was expecting a male out the 5, and i only got 2 which turned out to be these light stress proof gal.

the green light wasnt in the stress zone, promise. i wanted to see if it wud affect the growth of the others, it dint. but it feels weird. cos it light sthe room. anyhow..

i removed the plants to be punished at the end of the day cycle, kept em in dark for 5-6 hrs, then switched on main lights for an hour or 2, then back in dark for 5 hrs ish.

in the first week was covering individual branch's with a sealed end'd kitchen roll tube, so each cola got punished thru the day. an hour here, an hour there, really goin to town on em.

nada......

so i got 2 rooted clones now. and the trichs on the stressed planst are startin to turn GoLd.

alchemy at its finest, turnin bat shit n stinky fish emulsh into fkn Au!!

jah bless, praise allah, god almighty, father in t' heaven. i kneel at thy feet. tears, of rapture, the 1, in the many.

alpha, omega. love.

had a light fall on both chsls and a ssh, crushing their stems...we'll see how emergency splints help..

smokes like, did i say that or just think it...

ive been making good progress with my short ryders check me sig

try hermie it somehow i dont think that will be hard

As far as im aware all you have to do is look at those blueberrys the wrong way

just to add i grew a bag seed along with my top44 on my 2nd grow, the top44 were normal seeds i found the females etc and grew them with the bagseed, the bagseed what appeared to be female hermied somewhere along the grow and shagged the female top44 and produced quite a few seeds, i grew all these seeds in the smallest pots i could get with no veg for fun to see what they were and all were female no hermies!, and was quite nice a smoke, now i wished i kept some of the fuckers but it worked for me
