a thread with over 355 posts, and you need more details?

read first IMHO.

bryansm

150w floro up untill day 7
600w HPS from day 7 untill finish
12x4x8 closet with enough ventilation to make the door shut.
daytime 78-80 degrees
night 74-76 degrees
humidity 45-50%


i transplanted on day 10 from a flat to trade gallons.
when i added the bananas on day 14 the plants were loving the new room to grow.
From then on out plants showed strange symptoms. Vertical growth pretty much stopped and the stems just started looking crazy. i dont really know how to explain but they just looked like the stems a mother plant would have. Fat and woody.

thought it was the ethylene but went on with it anyway. then i came across this:

It was in 1864, that leaks of gas from street lights showed stunting of growth, twisting of plants, and abnormal thickening of stems (the triple response)(Arteca, 1996; Salisbury and Ross, 1992). In 1901, a russian scientist named Dimitry Neljubow showed that the active component was ethylene (Neljubow, 1901). Doubt discovered that ethylene stimulated abscission in 1917 (Doubt, 1917). It wasn't until 1934 that Gane reported that plants synthesize ethylene (Gane, 1934). In 1935, Crocker proposed that ethylene was the plant hormone responsible for fruit ripening as well as inhibition of vegetative tissues (Crocker, 1935). Ethylene is now known to have many other functions as well.

I thought that pretty much nailed what was going on pretty well. I did everything the same way as i always have. the only differences were the bananas and a uvb light added at 3 weeks into flowering; the bananas were long gone by then. ohh and they were not the same bananas the whole time, i swtiched em out.

I don't know what to tell ya...sounds pretty ledgit to me.

but I think it's strange that you're the only one that has complained about this, besides the guy that put them under a dome to trap more ethylene.

apparently it's like it is with everything, anything in excess is not good. period. even the most healthy things can become killers. people have even died from drinking too much water in one sitting.

possibly a strain that's more sensitive to it? maybe there was all ready a lot of it in the air around you...do you live near an orchard of some kind? do you know your PPM?

I believe fully that too much of it would indeed give a negative effect, I just can't get through my head that one or 2 or even 5 banana's could give off such an amount of ethylene. maybe there was a sort of pesticide on the banana that killed your plant, or a wierd bacteria from a dirty boat...who knows

eitherway, I think the banana thing is cool, but I'd rather let mother nature do her thing. the more we dick with nature the more we alter geneticly what it's suppose to be. eventually I believe it'll give a negative effect.

i have a similar religion , wk 2-4 if ph is high in range more f low more m
could explain hemi , also ethylene gas induces flowering in many plants .

smoken_kind

4 Bagseed plants, I used bananas for weeks 3 & 4.
I've been flowering for 8 days, last night I pulled 2 males and the other 2 are showing female flowers.

Do we know of any tests on plants like Kali Mist that aren't available 'feminized' or other plants that might be hard to feminize.
I would expect that the ethylene would act more as an indicator to the plant as to what sex to become rather than an actually driving force... hence the small amount produced by a banana having a success rate as discussed in this thread... a lot different from the report of plants absorbing ethelne directly from street lamps causing overly vegetated plants
As to why the plant becomes male or female it probably all has to do with regional genetic origin... phenotype and environmental condition. The plant has been evolving over 10,000 plus(am i way off on that?) seasons and is selectively engineered to respond to season cycle/condition circumstances to sex itself in the most productive way.
ie- a male coming of an undernourished, stressed late growing sprout is reciprocated in it's early easy release of polin by healthy, budded up female plants powerful enough to fully develop seeds with as much pollen it can get at any time... So as a plant healthily develops it naturally triggers itself... ethelyene is produced as growth rate is limited by less than one condition and extra energy is burnt off into hormones... ethelyene...
So by placing banana's near your plant your only circumventing your plants 'survival/selection ingrained' tendency to be the proper sex for it's conditions and age in the season (hence flowering before 3 weeks increasing rates of males).
By simply bypassing this effect you aren't altering the genes in anyway... your plant would probably look alot more tumorous and fucked up if the genes were mutated that much... your weakening the strain if you breed any of those females though... as were they in the wild they'd be less likely to produce male's rather than weak struggling females.... weak struggling females mean weak specie/strain. This also goes to point that the traits passed on by pollen form the minority and less stable traits to a seedling... enabling only successfully "selectively"" enhanced " seedlings (from good pollen) from retaining a trait and passing it on from a stronger female side of the propagatory situation...
Just my two cents... you get good males passing on solid traits that dominate a females seeds... your gonna get a bunch of healthy females from those seeds as they will be strong in there environment... to produce a whole other crop of plants determined to become healthy (become female) not necessarily become (male). Through this system the good traits of a male (other than his ability to become a male) are strengthened... which balances the system (its like a tier system) Cause obviously producing more male plants isn't going to strengthen a strain... you need seeds to to do that... This goes to say hermies are a natural part of the cycle as well... if a patch of females doesn't get pollinated because the nearest 'poor' conditions where males would develop are so far away... only the weakest (least stable breed/strain) would have hermied out... leaving the next season in the field to be comprised of 'Feminized' seeds (and whatever trees reveg of last season) So these hermie seeds not only have a high chance of being female dominant because they are in a bountiful field and also cause they're from a self pollinated female... But they also have a high chance of producing male parts,pollen/more seeds...
so basically as this system goes around females breed them selves into male' and strong strains based on the traits that weaken them (stability wise) which are the traits passed on from the weaker plants of the previous generation of "strong" males... and thusly interweave there own good traits with the good traits of the original male, and only the good traits, hence the 4,5 or 6 seasons of female dominant plots. THC strains should be bread under UVb death... only the plants with THE MOST CBD/THC deflecting UVb(which mutates/kills DNA) would have viable seeds... Take these females and mate them with a the mails of the different strain grown under similar conditions... Two high UVb perpetual grows with the males and females swapped out will build a strong THC strain after a few seasons, if you increase the other conditions to extremes you can build strains with other strengths as well.. i want a strain that self LST's... thats just nonsense though
Enjoy reading this! I recomend smoking a bowl beforehand!
I've written this to the best of my ability in reasoning over what i know, it could be wrong... but i do believe in the banana religion for producing sensi crops... just try and throw away those seeds... keeps the species alive (properly breed that shit)

There has been much debate as to whether or not ethylene promotes feminization. Many member of this site are intrigued by the idea, but not overly convinced, on account of the lack of evidence.

WELL I HAVE THE EVIDENCE.

I'll cut to the chase, their have been scientific experiments and tests performed to prove that ethylene promotes feminization in cucumbers (No studies were done on marijuana, yet I feel the theory must stand true for both). Results were conclusive and the test proved that ethylene gas...

(direct quote from website) "The data suggest that ethylene participates in the regulation of sex expression by promoting femaleness."
