I remember OD .... even went out and bought some. But of course when it came time to germinate, that memory flew right out the window ... thank goodness bc chimed in with this thread, ended up with 72% females! Maybe with a folic acid and banana combo, that ratio can be improved upon the next grow

That is exactly my plan JV. And I will do some side by side experiments too. My only problem is it takes months in my garden for us to know the sex....
Some with bananas and some without but all will get folic acid.

Peace- OD

Plant Hormones and Thiamine (Vitamin B1)

Hormones are produced naturally by plants, while plant growth regulators are substances applied to plants to influence growth and development in some way. All plant hormones and plant growth regulators (PGR) are in fact 'organic' in that they contain carbon and nitrogen however these can be divided into either synthetic (man made) compounds (such as IBA used in rooting powders/gels, or cycocel) that mimic naturally occurring plant hormones, or they can be naturally occurring substances that have been extracted from plant tissue (e.g the cytokinin 'zeatin' is extracted from maize). Whether a plant growth regulator is naturally derived and extracted from plant tissue or synthetic can have a major effect in terms of the result on plant growth. Naturally derived PGRs, can be absorbed and deactivated inside plant tissues where as synthetic PGRs due to their chemical structure are resistant to break down inside the plant.

Plant growth regulator substances are usually applied in low concentrations to plants as only a few parts per million is sufficient to have the required affect. Most often these types of compounds are applied as a foliar spray, although some work best if applied as a seed soak, or media drench around the plants base. The method of application of various PGRs depends on what compound is being used for a particular purpose, but usually their effects are short lived, and repeated applications are required to achieve the desired result.

There are 4 groups of PGR compounds: these are Auxin, Gibberellins (GA), Cytokinin and Ethylene. While auxins, gibberellins and cytokinins are considered to be growth promoters. Ethylene is a gas which can cause leaf abscission and ripening of certain types of fruit, however when applied at the correct concentration as Ethrel (foliar spray) it has been used to induce femaleness in flowers of cucumber and other dioecious plants.

Auxins are most widely used to stimulate root formation on cuttings and are often used in the form of NAA or IBA, although they have other horticultural applications as well such as promoting fruit set in some plants such as tomatoes.

Gibberellic acid (GA) can have the effect of increasing plant height by elongation of the internodes on plants. GA also increasing the rate of germination and break bud dormancy. GA stimulates cell division and elongation, and will stimulate bolting or flowering in some plants by causing cells in the flower bud to divide and expand lengthwise more rapidly than normal. Synthetic compounds such as Cycocel have been produced which are 'anti-gibberellins' and force a plant to remain dwarfed by blocking the elongation effect of the plant's natural Gibberellins.

Cytokinins (such as BA or BAP, or Kinetin, Zeatin): Cytokinins promote cell division, they also promote the growth of lateral buds and stimulate leaf expansion resulting from cell enlargement. Cytokinins also slow down ageing or senescence in leaves, allowing them to stay green and actively photosynthesising for longer.

When using PGRs the timing of application is important. Many PGRs only work when applied at a certain stage, and some are more effective if applied in the root zone where up take can be much greater than when spayed on the foliage.

Many of the other naturally derived PGRs are best applied to the plant part which they are to effect (i.e sprayed on the flower buds, foliage, or applied to where roots are to form).

Now does anyone have any experience using ethrel? What concentrations is good to promote flowering? Should it be applied to the roots or the leaves?

I have no idea as to the answer to any of your questions. But the point of this thread is to NOT have buy some special order product to increase the ratio of females.

Four seeds went down, four sprouted. That was about 6 weeks ago and I put bananas under them for weeks 3-5. I have two confirmed females, one suspected male (I am 80% sure it is male) and one that hasn't lifted its skirt or pulled down its pants. If I end up with 3 out of 4 well, that means that the bananas had no effect at all (with all other things being equal). I have never had a ratio of 75% or under. Shit, I don’t remember the last time I had a male. I'm not taking a shit on this religion because we all know that things, between seeds, are never equal.

Im not sure I understand the point of NOT buying something extra. I think most people in this thread are buying something extra; the banana. I am using them too now because of this thread.

SkierGuy23

You just don't get it do you? The idea of the banana " is to NOT have buy some special order product to increase the ratio of females."*

I'd like to see you get some of the additives at a convenience store or grocery store (where most people get their bananas).
