Who's the idiot who said cannabis is not classified?It is called weed because of it's hardiness and tenacity... it is not actually a weed. Cannabis has no classification.
It is neither plant nor tree nor weed... learn it.
Do you think Dutch Passion is listening to this advice?For you potential breeders out there, you should not follow these rules as any (would-be)males that change to female because of enviromental condition may have the hermaphroditic gene and should not be used with breeding, for my non-breeding tomatoe plant moms tho i folow those rules to a "T".
Last time I checked: Sativa and indica have not been classified as separate species. It's still not known whether it's a separate species or a sub-species. As if it mattersWho's the idiot who said cannabis is not classified?
Cannabis (Cán-na-bis) is a genus of flowering plants that includes three putative species, Cannabis sativa L.,[1] Cannabis indica Lam.,[1] and Cannabis ruderalis Janisch.
I know there have been a few topics on how to achieve a higher female percentage, but here is an article that had a few more conditions added to it. Check it out courtesy of cannabis-seed-banks.com
PERCENTAGE OF FEMALES
From literature it appears that the growth of a male or female plant from seed, except for the predisposition in the gender chromosomes, also depends on various environmental factors. For growers who are well experienced, percentage of female plants is 60% - 90% female, but less experienced growers can end up with 100% male plants. The environmental factors that, according to literature, influence gender are:
- a higher nitrogen concentration will give more females (at the three-pairs-of-leaves stage and continue for two or three weeks).
- a higher potassium concentration will give more males (at the three-pairs-of-leaves stage and continue for two or three weeks).
- a higher humidity will give more females (at the three-pairs-of-leaves stage and continue for two or three weeks).
- a lower temperature will give more females (at the three-pairs-of-leaves stage and continue for two or three weeks).
- more blue light will give more females (at the three-pairs-of-leaves stage and continue for two or three weeks).
- Fewer hours of light will give more females (at the three-pairs-of-leaves stage and continue for two or three weeks).
- In later stage, as you increase the light, the plants grow faster and show more females/less males. Sixteen hours of light per day seems to be the best combination, beyond this makes little or no appreciable difference in the plant quality.
- Another idea is to interrupt the night cycle with about one hour of light. This gives you more females.
- Spray dilute Fish Emulsion ( 1 tablespoon per gallon ). When the plants have three sets of true leaves, plus the top sprout, give them a wetting spray of Fish Emulsion. Do it once a day for three of four days. Top and bottom of the leaves.
- To achieve 100% female plants is to expose young seedlings for several hours to an atmosphere of Carbon Monoxide. It doesn't hurt the plants, but it could kill you.
- 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.
- 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.
It's not only about genetics. Plants don't immediately develop gender, right out of the seed. Just like human babies, they don't start with a sex and develop one over time; however, they do grow into their first gender, eventually.Also, less experienced growers can end up with 100% males. wtf are you talking about? Was that even in the article?
Experienced growers on this site have had nearly these kind of results. It's about genetics.
Also what's the part about a seeds predisposition? This means that the seed is predisposed to be a certain sex... which means that in all likelyhood, despite whatever environmental factors/changes you introduce the plant will turn out the sex it was meant to be.
To my mind, by fucking around like this you are merely increasing your chances of getting hermies.

You can't really talk about genetics if you don't know what seed predisposition is. But anyway, seed predisposition doesn't mean that changing environmental factors won't cause plants to turn out female. If a seed is predisposed to be female, it's still easy to come out with a male. People just don't often try to make plants male--unless they are breeding with FOG--or mess up badly enough to do so.
All plants are "hermies". kiss-ass They live in a cycle, going from male, to female, to male, to female, with stages in between. If you want females, exposing seedlings to CO for a long period of time works. Later, they may change to male if they are exposed to other male plants, or if some other environmental factor causes them to change--another example, shock.
A weed is an unwanted plant - my ladies are never that.well to be corrected cannabis IS A WEED, yes it is a weed, and called weed,, hence the name.
Cannabis isn´t a plant?? Mine were last time I looked.Cannabis has no classification.

That's incorrect in regards to cannabis (and human babies by the way), they don't change their sex ever. Even if a female cannabis plant produces hermaphroditic growth. Female dioecious plants (and they are female due to a lack of Y chromosomes) like cannabis, can produce pollen but it is female pollen (for lack of a better term). It is different than male pollen (XY pollen). Only male dioecious plants can produce pollen capable of producing male offspring. And male dioecious plants, like cannabis, do not produce hermaphroditic growth.It's not only about genetics. Plants don't immediately develop gender, right out of the seed.

Preety sure everyone posting in this thread has died of old ageI must be honest...this sounds like complete bullshit. Everything about it. Sources?...
WEll I'm new here just wanted to say that incase anyone else actually tries to follow. And ya...the rightful old age of two years old/Preety sure everyone posting in this thread has died of old age
