Femmed Seeds Outdoors how to make your own femmed seeds

Hi, I am looking for information on making my own femmed seeds.
I know of one way besides stressing your plants out.
I would like to hear from someone who has used this way to get femmed seeds.

I am just starting to do a daily spray on one branch with a 50ppm solution of GA3 or Gibberillic acid a plant horomone used by the food industry to set fruit (seedless varieties), increase amount of blossoms/flowers.
In one week my females one branch should be sending out the beginnings of a male flower. As the male balls mature and most are ready to puke the pollen I will cut it off and with a small fan blow the pollen over my 3 females.
I am not sure if this is the way it will go but I am going to try it.

I need to know how long it'll take for the first male flowers to show. how often do I spray and for how long a period?

 

This is something I( found on a site I could order it from) www.rarexoticseeds.com


Gibberellic acid was first discovered in Japan in 1935 as a result of the study of a condition common in rice plants called "foolish seedling" disease, which caused the plants to grow much taller than normal. The effects of gibberellins weren't widely understood until years later. Gibberellic acid, GA3 is a naturally occurring plant hormone that regulates the growth of plants, including triggering seed germination. Gibberellic Acid is not manufactured; it's a natural product extracted from the Gibberella fujikuroi fungus. There are over 100 known forms of gibberellic acid; GA3 is the most effective.


Seeds of many plant species require exposure to low or high temperature within a certain period before they will germinate. This process is called thermal stratification. Alternatively, the hormone gibberelline can be used to break such dormancy.


Alcohol soluble GA3 Powder 90% is the most economical form of Gibberellic acid. It is soluble in 70% common rubbing alcohol. Before it can be used is must be turned into a liquid. The amount of Gibberellic acid that needs to be used is very small. Drop the correct amount of powder in a small bottle, then add a few drops of rubbing alcohol. The only reason to use alcohol is to dilute the Gibberellic acid powder. Use just enough alcohol to wet the gibberellic acid powder. If after a couple of minutes you can still see some powder add a few more drops of alcohol. Then just add water to get he right concentration. It is often being said that alcohol will damage plants. Yes, but not in the very low concentration needed to dissolve Gibberellic acid. 90% GA3 powder will not dissolve in water. Once mixed it loses viability within a week, even if refrigerated.


You don't need much of the solution to soak your seeds, just enough for the seeds to fully swell. Most seeds can be soaked in the small poly-bags. Tiny seeds should be folded up in a filter paper for ease of handling when soaking. Larger seeds can be soaked in a pill bottle or small jar.


To know the concentration, replace X and Y, (X mg / Yml) x 1000 = Z ppm


To know the amount of solution to make to get a certain ppm, replace X and Z, (X mg / Z ppm) x 1000 = Y ml


To know the quantity of powder to use, replace Z and Y, (Z ppm x Y ml) / 1000 = X mg


For exemple: 100mg of GA3 in 200ml of water gives you 200ml at 500 ppm (part per million). 100mg of GA3 in 400ml of water gives you 400ml at 250 ppm. 1g of GA3 at 90% concentration will be supplied as a powder in a small ziplock bag, sufficient quantity to make a 2 liters of solution at 500 ppm. You should have enough for a couple of years.


Use strong solution, 500 ppm, on very hard to germinate seeds; and a 250 ppm on seeds that are just hard or slow to start. Seeds enclosed in a hard coat may be submit to a higher concentration, 750-1000 ppm. You can scarify the seeds at first. Soak seeds for 24 hours and at most three days for the ones enclosed in a hard coat. Keep the seeds at room temperature with occasional careful shaking. The seeds may then be sown. Don't use it on easy to start seeds unless you dilute it greatly, like 25-100 ppm, and soak them only for 2-3 hours. Normal, easy-to-sprout seeds will become very elongated and stretched out, then die if GA3 is used on them. Concentrations of about 2 ppm can cause tubers to sprout earlier.


Gibberellic acid can also influence the timing of flowering, flower gender, flower size and increase the number of flowers. If a plant is sufficiently developed, premature flowering may be induced by direct application of GA3 to young plants. Formation of male flowers is generally promoted by concentrations of 10 to 200 ppm, female flowers by concentrations of 200 to 300 ppm. You may have an increase in the number of flowers by direct application of GA3 to young plants, at 25 ppm.





When there is difficulty with fruit set because of incomplete pollination, GA3 may be effectively used to increase fruit set. The resulting fruit maybe partially or entirely seedless.


GA3 applied near the terminal bud of trees may increase the rate of growth by stimulating more or less constant growth during the season. Since GA3 regulates growth, applications of very low concentrations can have a profound effect while too much will have the opposite effect.


Although GA3 is not listed as a poison, the following precautions should be observed. Flush with water any GA3 that may get into the eye. Avoid skin contact if possible and wash away any contact with soap and water. Avoid ingestion of GA3.

 

Also I've heard of a "Silver something" solution you spray on the plant. This might be the place to have instructions for many ways of femming seeds

 

ive heard of this other acid.. not sure what its called, but its suppose to be used to germinate them, and say you germinate 25 seeds 2 might actually germinate the rest die.. but the ones that survive are suppose to be super potent , so potent that its actually toxic or its full of the toxin not sure... your suppose to breed that plant and throw it away cus its so potent and full of toxins, the seeds left over from them are suppose to be ok to grow/ smoke or w/e when finished. its suppose to just make super potent dope.. not sure if its true , ill try and find it again i was reading it about 2 or 3 months ago..

 

Sounds like this Gibberillic Acid, it has numerous forms just that GA3 is the best form to use.


Yes please let me know what you find out, I was hoping one of the "experienced" growers would step up and tell how its done in the seed industry, but I guess those secrets (if there are any) are not given out.

 

i THINK this is it, but when i read it a while back it was on a diff page about pot, could not find the original that i was looking at YET..


Salicylic acid (from the Latin word for the willow tree, Salix, from whose bark it can be obtained) is a beta hydroxy acid (BHA) with the formula C6H4(OH)COOH, where the OH group is adjacent to the carboxyl group. This colorless crystalline organic acid is widely used in organic synthesis and functions as a plant hormone. It is derived from the metabolism of salicin. In addition to being a compound that is chemically similar to but not identical to the active component of aspirin (acetylsalicylic acid), it is probably best known for its use in anti-acne treatments. It is poorly soluble in water (0.2 g/100 ml H2O at 20°C


Salicylic acid (SA) is a phenolic phytohormone and is found in plants with roles in plant growth and development, photosynthesis, transpiration, ion uptake and transport. SA also induces specific changes in leaf anatomy and chloroplast structure . SA is involved in endogenous signaling, mediating in plant defense against pathogens.[2] It plays a role in the resistance to pathogens by inducing the production of 'pathogenesis-related proteins'.[citation needed] It is involved in the systemic acquired resistance [sAR] in which a pathogenic attack on one part of the plant induces resistance in other parts. The signal can also move to nearby plants by salicyclic acid being converted to the volatile ester, methyl salicylate,Salicylic acid was also isolated from the herb meadowsweet (Filipendula ulmaria, formerly classified as Spiraea ulmaria) by German researchers in 1839. While their extract was somewhat effective, it also caused digestive problems such as gastric irritation, bleeding, diarrhea, and even death when consumed in high doses.





ProductionSalicylic acid is an organic acid biosynthesized from the amino acid phenylalanine.


Sodium salicylate is commercially prepared by treating sodium phenolate (the sodium salt of phenol) with carbon dioxide at high pressure (100 atm) and high temperature (390K) - a method known as the Kolbe-Schmitt reaction. Acidification of the product with sulfuric acid gives salicylic acid:





It can be prepared by the hydrolysis of Aspirin (acetylsalicylic acid)[4] or methyl salicylate (Oil of Wintergreen) with a strong acid or base


again not sure if this is what i was looking at b4 because it was worded diff,(as in a stoner was wrote it) il keep looking for the other page tho...sounds pretty intense..

 

too bad they didnt have instructions on strength, frequency and duration,


of how to use it. I've heard the aspirin myth but have never heard of it being used to success, nor have I tried it yet.


I've keep watching and thank you for getting the info

 

GA is applied to branches before flowering then again 2 weeks after flowering. I think.

 

Yea GA, silver thiosulfate and colloidal silver are the only three things I know of that you can use to interfere with the ethylene pathway to revert sex.
