Besides buying the seeds from trusted seed banks, there are also other alternatives that growers can use to produce their own supply of female seeds. Just think of how awesome it must feel to produce a batch of Bruce Banner strain seeds without having to purchase from a seed bank.
Make sure to have protective materials such as goggles, gloves, and a safety mask when mixing the solutions. STS can leave behind burns on one’s skin and is also toxic when inhaled. Remember not to use any metallic objects when producing STS as these can reduce efficiency and alter the material’s composition. Only use plastic when making STS.
Females can also be distinguished by their nodes which look tiny balls with a bunch of little hairs growing out of them. Female cannabis plants produce flowers and usually have high amounts of THC. Raising feminized marijuana seeds has a 95% chance of producing female plants.
The first thing must do is to put 20 ml of distilled water into a plastic cup. Dilute at least 300 mg of silver nitrate into the cup of distilled water. Silver nitrate can be obtained from Argenpal sticks which are available in online pharmacies. Each stick of Argenpal contains 42.5 mg of silver nitrate. The silver nitrate is found at the tip of each stick. Argenpal is a medication that is used for getting rid of warts.
One can collect the male pollen sacs and use them to pollinate other feminized plants. To do this, one should evenly cover the female’s buds with pollen 2 to 3 weeks into their flowering stage. Females that get pollinated in this manner will begin producing all-female cannabis seeds. One must observe caution when pollinating plants through the rodelization method so that one will only pollinate some of the plants while leaving the other ones alone so they can be used later for personal consumption.
Understanding stomatal (pores on leaves that open and shut like a eye)
indole-3-acetic acid (IAA) = Auxin, Is a plant growth hormone.
Ethylene, A natural plant hormone used in agriculture to force the ripening of fruits (usually effective at 77f degrees). Is known as a flammable gas. Ethylene’s hydrate is ethyl alcohol. Stimulates leaf and flower senescence (process of deterioration, leaf yellowing), boosts root growth, known to prolong vegetation in light change, however in some plants will jump start flowering, boosts stem and branch production along with size, counteracts auxin effects, boosts cotyledons by 300% (first 2 weeks of growth). Natural sources of ethylene include both natural gas and petroleum; it is also a naturally occurring hormone in plants, in which it inhibits growth and promotes leaf fall, and in fruits, in which it promotes ripening.
I have not did testing etc, and still working on getting best method for this, but if people have other info feel free to add it. There is nothing worse than having a cross idea and then get all males. So this is a work in progress much like my turpenes research. Selfing a plant in this fashion would make male only so crossing to another plant is advised.
Cytokinins Chemistry, Activity, and Function
By David W. S. Mok, Machteld C. Mok
Metabolism and Molecular Activities of Cytokinins
edited by J. Guern, C. Peaud-Lenoel 1980
Feminization of genetic males is possible by Cytokinins which induce mRNA population of female type (Delaigue 1984 and 1986). A classical cytokinin effect is retardation of leaf senesnence. Highly active in sensescence promotion is methyl jasmonate. Ethylene, ABA, and possibly cytokinins are involved in plant response to environmental stress (Neyer 1987).
Cytokinins role in stomatal mechanisms has been further studied with regard to cytokinin – ABA interactions (Blackman and Davies 1984) and age-related changes in stomatal responses (Blackman and Davies 1984) as well as light conditions (Guring 1984). Cytokinins might reduce stress injuries (Balasimha 1983) and increase stress resistance (Titove 1986). So stress should lower cytokinins and thus creating males. Naturally occuring cytokinins have been reviewed by Mcgaw in 1984 and Palni in 1983 and 1986. Scott and Horgan also provided naturally occuring cytokinins in 1984. Females appear to be Zeatin based. 1-hydroxy-methyl zeatin from wheat (Rademacher and Grabe 1984) and 1-methyl zeatin along with 9-riboside (Surico 1985, Evidente 1986, and Itaya 1986) was perfect examples of naturally occuring cytokinins along with 6-benzylamino-purine-9-b-d-riboside (Ernst 1983). Potatoe tubers contain numerouds cytokinins along with a extremely high amount of the cytokinin oia-zeatin riboside (Hashizume 1985). Typically cytokinins decrease drastically in potatoes after harvest however in bud sites the cytokinins increased 20-40 times (Turnbull and Hanke 1985).
