Ok according to the following:
Ethylene Gas C2H4
An apple produces a higher amount of Ethylene gas.
Also, I figure if your doing this as a business producing clones in a legal environment. Meaning overseas not here in the States...you could call a company like Airgas and just buy a cylinder of Ethylene and have a regulator and release a few times a day.
But using a Banana peel and the seeds...this makes the seeds females...so why not use pure Ethylene if your producing female seeds...this is also something to think about.
There isn't a guess if this works anymore, its already been done before according to Wiki.
Ethylene - Wikipedia, the free encyclopedia Quote:

Ethylene acts physiologically as a hormone in plants.[12][13] It exists as a gas and acts at trace levels throughout the life of the plant by stimulating or regulating the ripening of fruit, the opening of flowers, and the abscission (or shedding) of leaves. Its biosynthesis starts from methionine with 1-aminocyclopropane-1-carboxylic acid (ACC) as a key intermediate.

This statement here also confirms this.

In 1935, Crocker proposed that ethylene was the plant hormone responsible for fruit ripening as well as inhibition of vegetative tissues (Crocker, 1935).

List of Plant Responses to Ethylene
* Seedling triple response, thickening and shortening of hypocotyl with pronounced apical hook. This thought to be a seedlings reaction to an obstacle in the soil such a stone, allowing it to push past the obstruction.
* In pollination, when the pollen reaches the stigma, the precursor of the ethylene, ACC, is secreted to the petal, the ACC releases ethylene with ACC oxidase.
* Stimulates leaf and flower senescence
* Stimulates senescence of mature xylem cells in preparation for plant use
* Inhibits shoot growth except in some habitually flooded plants like rice
* Induces leaf abscission
* Induces seed germination
* Induces root hair growth – increasing the efficiency of water and mineral absorption
* Induces the growth of adventitious roots during flooding
* Stimulates epinasty – leaf petiole grows out, leaf hangs down and curls into itself
* Stimulates fruit ripening
* Induces a climacteric rise in respiration in some fruit which causes a release of additional ethylene. This can be the one bad apple in a barrel spoiling the rest phenomenon.
* Affects neighboring individuals
* Disease/wounding resistance
* Triple response when applied to seedlings – stem elongation slows, the stem thickens, and curvature causes the stem to start growing horizontally. This strategy is thought to allow a seedling grow around an obstacle
* Inhibits stem growth outside of seedling stage
* Stimulates stem and cell broadening and lateral branch growth also outside of seedling stage
* Synthesis is stimulated by auxin and maybe cytokinin as well
* Ethylene levels are decreased by light
* The flooding of roots stimulates the production of ACC which travels through the xylem to the stem and leaves where it is converted to the gas
* Interference with auxin transport (with high auxin concentrations)
* Inhibits stomatal closing except in some water plants or habitually flooded ones such as some rice varieties, where the opposite occurs (conserving CO2 and O2)
* Where ethylene induces stomatal closing, it also induces stem elongation
* Induces flowering in pineapples

So its already been proven. Enough said. I know I'll be using it to guarantee my plants to be female.
I also found this on another website...so we might not have to go through all that trouble after all.

there's a product called "Sensa-Spray" that is used to induce flowering in plants ( aka marijuana). you mix the spray solution with water then spray it onto the plants. the product activates when it is mixed with water, decomposing into ethylene gas.
its about $20 for a 2oz bottle which makes 2 quarts of solution. a simple google search using the search phrase "Sensa-Spray" will yield alot of sites that sell it.
try adding some to the water that you use in your jars. the gas will build up in your jars creating a nice ethylene filled environment. or put a glass of water into your growbox and add a few drops of sensa-spray to the water everyday.

I normally don't post or read over at IC, and I found some more information there. According to a few, using a Sensa-Spray mixture with water, and soaking seeds lead to 100% females. That was 4 seeds per germ. For a total of 5 germinations. So 20 seeds total. All ended up being female. That's a good number and would be hard to get no males in 20. The odds are against you.

I use a product called Sensa -Soak It contains a product called ethylene I get about 9/10 fem when using this combined with another product called Sensa-Spray .The spray is usedf at the start of flowering and then once more in 10 days time .(It really makes the plants wilt and if you have a breed which is a bit Hermy It seems to repress maleness and realy bring femaleness to the for.

Oh and you can get Sensa-Soak here.
PLANT HORMONES
Its an Australian company though...the product costs roughly 30.00 USD and 35.00 in AUD.
I couldn't find it anywhere else. Damn that was a lot of typing
