If anyone out there needs Gib, I can supply it in liquid form at either 50, or 100 PPM. For 50 PPM, I ask $15.00 @ Qt., and at 100 PPM it's only $25.00 @ Qt., suspended in reverse osmosis filtered water & checked for ph, ready to spray right out of the bottle, & that much can go a very long ways. It will last thru several growing seasons, even if you're trying to go commercial with feminized seed production, as all it takes is one good properly treated female, producing male flowers, to pollinate a huge number of plants, producing thousands of seeds, eh. Contact me at s12345@sbcglobal if you're interested. I've seen it selling for $29.95 for 1/2 gram on the Internet. I offer a much better deal, and if you want a larger quantity, I can make it even cheaper. I can do this because I'm a commercial walnut grower and have access to commercially packaged ferts & ammendments that only commercial farmers can get. And in spite of many postings to the contrary, gibberillic acid is NOT synthetic. It is a naturally occurring plant growth hormone, occurring in nearly all plants to some degree. This Gibb is approved for use on ORGANIC crops. It is used on all the seedless grapes grown, that many of you love & consume regularly. I simply reduce the concentration by adding reverse osmosis filtered water to the product to reduce its strength. If you're still not sure just what gibberillic acid is, then read this from the manufacturer, who makes the product I sell, after adjusting it to the strength needed for feminized cannabis seed production. It can also be used to increase the growth rate of Cannabis at a reduced strength & applied earlier in the season:

Some commonly asked questions on the use of Gibb on table grapes:
1. Whatâ??s the ingredient?
The ingredient is gibberellic acid, a naturally occurring plant growth regulator found in most plant species. Gibberellic acid is produced by the process of fermentation, where a pure strain of the fungus Gibberella fujikorai is grown in an aseptic medium. The unsurpassed quality of this Gibb stems from the highly sophisticated process and unique quality control procedures that the manufacturer uses to make gibberellic acid.

2. How does Gibb work in seedless table grapes?
The active ingredient is gibberellic acid, a natural plant growth regulator found in most plants. Gibberellic acid regulates several different processes in plants. Perhaps the most well known effect of gibberellic acid is to promote the growth and development of plant organs, flowers, fruits, leaves and stems. Seedless table grapes are deficient in gibberellic acid, as the main source of it are the seeds. In seedless grapes, Gibb is applied before bloom to â??stretchâ? the cluster. The end result of the gibberellic acid regimen is a large, loose cluster, with large and uniformly sized berries that mature evenly. All seedless grapes grown for fresh market are grown with gibberellic acid applications. Currently, many varieties of seeded table grapes are also treated with gibberellic acid, as berry size is also
improved in these varieties.
3. What are the ideal conditions to apply Gibb to grapes (or cannabis-Steve)?
a) Temperature: For Gibb to be absorbed and work in the tissue, the plant metabolism must be active. Thus, very low and very high temperatures must be avoided. Best results are obtained at temperatures between above 60˚F and below 90˚F. In dry hot regions, Gibb is usually applied at night.
b) Slow drying of the spray material allows for higher penetration of ProGibb into the plant tissue. Avoid low relative humidity (less than 40%) and windy conditions. Early mornings and late evenings are usually desirable spraying times, as long as the temperature is adequate.

4. How does Gibb affect the quality of table grapes?
Gibb improves the quality of table grapes by producing a large, loose cluster of well-developed berries. Flavor and aroma develop normally in Gibb treated grapes, providing that adequate cultural practices in the vineyard are followed. It is also important to harvest the grapes at the optimum maturity to attain maximum eating quality by the time the fruit reaches the market. Because a looser cluster is less prone to be attacked by fungal diseases, Gibb-treated grapes may in some cases require less fungicide sprays.

5. Does Gibb use in grapes fit IPM and IFP practices? Does Gibb qualify for organic farming?
The active ingredient in ProGibb (gibberellic acid) is labeled as naturally occurring by the regulatory agencies, and is exempt from tolerance establishments for all crops. Based on the inert ingredients, some of the ProGibb formulations qualify for IPM, IFP and organic farming practices.
7. Do adjuvants enhance Gibb efficacy?
Gibb is formulated to be used without the use of any additives. In many years of research we have found that adjuvants (spreader-stickers, surfactants, etc.) only help in some specific situations. When spraying conditions are ideal, and with good quality water, it is hard to notice the effect of adjuvants. In adverse spraying conditions (windy, dry, high temperatures) it is possible that a nonionic surfactant may help improve coverage and increase absorption. Also, a pH corrector is only necessary if the pH of the water is 8.5 or higher. Caution should be exercised since some surfactants and other additives may cause russet or phytotoxic reactions (burnt leaves-Steve).

I cannot get gibberellic acid locally, and refuse to order it online, so I am left with only one option, I think, a wacky lighting schedule. 12 on | 5.5 off | 1 on | 5.5 off Rating: 5
