How can you keep a female marijuana plant female?

Answer 1

If you want your female to develop seeds without having a male to pollinate her, there is a few tricks you can do. What you will be aiming to do is to force your female to turn into a hermaphrodite so it will generate it's own pollen sacks which you can harvest and pollinate her/it with.

Marijuana plants hate stress. Too much stress and it will die, just enough stress and it will hermie. You can try tricks like switching from warm air in the day to cold air at night, heavy constant wind, exposing the plant to light for a short period during the dark cycle, switching back and forth between flowing and vegetating, allowing her soil to dry out (You don't want to kill her!), then giving her water.

Another trick you can use will guarantee pollen sack growth, however, using this method means that the plant cannot be smoked, eaten or anything. It is just being used for pollen and seeds. This method involves foliar spraying with 30PPM (Parts per million) of colloidal silver once she enters the flowering stage once per day. She will soon begin growing pollen sacks. Once they start to develop, stop spraying the plant. Harvest the pollen and pollinate your plant with it. This will also guarantee feminized seeds as well. Only spray your plant in a well ventilated area away from pets, food and any plants that will become consumed.

And finally, there is rodelization. This trick is not overly reliable and also unfortunately makes the plant less than desirable for consumption due to the advanced age the plant will be at harvest time. This method involves just letting the female flower for much longer than it's peak. As a last-ditch effort to keep her lineage going, she will develop pollen sacks shortly before dying so she can self-pollinate and develop seeds. The downside of this method is that it appears that not all strains can be rodelized in that they won't develop pollen sacks at advanced ages.

One final method which is purely theoretical that I thought of, which I have not researched or tried would be foliar feeding with colloidal silver after revegging a plant. This benefits you in two ways. When a plant is forced to hermie, she will not be nearly as potent and secondly, colloidal silver can make the plant toxic. What you do is you harvest normally, but carefully. Harvest everything but the fan leaves and cut about 1/3 of the plant off the top. Leave some small buds on the lower part of the plant as well. Transplant her into new soil, try not to damage the root structure too much. Put the plant back into a 16/8 cycle (Or whatever you use for vegetating) and let her vegetate. It will take a few weeks for new shoots to grow. Early on while she is revegging, you probably will notice some heavily mutated leaves, this is normal. Be very wary about letting her nutrients run low. It is absolutely imperative you do not allow a nitrogen deficiency. If she loses her leaves, she will die. A good idea would be to feed her nitrogen-rich plant food after harvesting, such as blood meal, alfalfa meal, diluted (10:1) healthy human urine or straight nitrogen fertilizer. When ready, drop the lighting to flower the plant and start the foliar feeding with 30 PPM of colloidal silver daily until she develops pollen sacks, stop feeding her the silver and harvest the pollen and pollinate her. You will not get nearly as many seeds if you do this after revegging as the general yield is only 25%-50% of the original yield.

I should note that self-pollination causes seeds now have hermaphroditic genetics which may or may not cause the seeds to be more prone to turning into hermaphrodites than non-self-pollinated seeds. However, further breeding through self-pollination in the same lineage will result in genetic defects. Additionally, if the mother was grown from a feminized seed, the genetics could have been destabilized which can cause hermaphroditic seeds. However, there are advanced breeding methods to reduce it's tendency to turn hermaphroditic, like back-crossing, which is a special way to inbreed a plant to stabilize the strain, which can only be done on non-feminized seeds unless you cross another strain into it using a male.

Note about colloidal silver: Colloidal silver builds up in the human body, causing argyria, which is a irreversible, permanent blue-grey discoloration of the skin, organs and eyes. Some say it has benefits in the human body as holistic medicine, however no empirical study to date has shown that colloidal silver has even the slightest benefit, nor is it naturally found in the human body. Consumption of plants that have been sprayed with colloidal silver can cause argyria so it is suggested you do not consume any plant that has been sprayed with colloidal silver as it will have a much higher concentration of silver than products specifically marketed for consumption. As an additional precaution, I would not eat the seeds from a plant that has been sprayed. However, the progeny from a plant that has been sprayed is safe.

Answer 2

no. the time and amount of males around it will only influence the amount of seeds in the bud. absence of males will only encourage the female to grow trichomes, known to contain very high amounts of THC.

Answer 3

you can keep a marijuana plant 100% female by keeping any male plants away from it ..even a male plant in your neighbors yard can fertilize your plant even if it is inside your home.. as soon as a female plant is fertilized it produces seeds and a much less potent product ..also keepin your plant 100% female requires vitamins minerals and mantainance on some occassions. also a female plant can become a hemaphrodite by setting the flowering light cycle too early ..hope this helps

Answer 4

You don't. Like THC, the seeds come from the female plant. The male plant only produces pollen.
