Unlock Full Throttle Growth Boosting!
All plants regulate their growth, development, and behavior by Plant Growth Regulator (PGR) Hormones, which in most cases move through the plant from one part to another. Fertilizer provides fuel for plants to grow, but doesn't force them to do so. Hormonal signaling dictates the the plant to do so, and the fertilizer is like the 'gasoline' fuel (energy) to carry out such signaling.Think of it as fertilizer is the fuel, where hormones are the gas pedal (or brake pedal) of various plant growth characteristics.
By treating plants with PGR's you can not only alter the ways they grow, you can boost their growth at the same time. The reason is because it requires plant energy to synthecize these signaling phytohormone chemicals. This requires energies that during treatment spares the plants from needing to 'waste', meaning more of the energies the plants have access to are spent on the actual growth that the PGR's are signalling the plants to do.

GIBBERELLIC ACID USAGE GUIDE
Guide Last Updated: 3-30-14 (under construction)
Gibberellic acid (Gibberellin A3 aka GA3) is a simple gibberellin, a pentacyclic diterpene acid that tends to promote the growth and elongation of of all plant cells. It affects decomposition of plants and helps plants grow if used in small amounts, but eventually plants develop tolerance to it. GA stimulates the cells of germinating seeds to produce mRNA molecules that code for hydrolytic enzymes. Gibberellic acid is a very potent hormone whose natural occurrence in plants controls their development. Since GA regulates growth, applications of very low concentrations can have a profound effect while too much will have the opposite effect. It is usually used in concentrations between 0.01 and 10 mg/L (5-500 Parts Per Million). GA was first identified in Japan in 1935, as a metabolic byproduct of the plant pathogen Gibberella fujikuroi, which afflicts rice plants; fujikuroi-infected plants develop bakanae (“foolish seedling”), which causes them to grow so much taller than normal that they die from no longer being sturdy enough to support their own weight.
>Stimulate stem elongation by stimulating cell division and elongation.
>Stimulates bolting/flowering in response to long days.
>Stimulates bud development.
>Breaks seed dormancy in some plants which require stratification or light to induce germination.
>Usually maximizes germination speeds.
>Usually maximizes germination rates.
>Stimulates enzyme production (a-amylase) in germinating cereal grains for mobilization of seed reserves.
>Induces maleness in dioecious flowers (sex expression).
>Can cause parthenocarpic (artificial parthenocarpy) seedless fruit development (i.e. grapes).
>Can delay senescence in leaves and citrus fruits.
>Causes feminized seeds in certain plant types (i.e. cannabis).
>Gibberellins break dormancy of buds and tubers. But in root tubers it inhibits the development of the root tuber.
>Gibberellins help in the flowering of many long day plants.
>Increased fruit sizes.
NOTE: Responses will vary depending on the type of gibberellin, methods & amounts used, and the plant species involved.
>In laboratory and greenhouse settings to trigger germination in seeds that would otherwise remain dormant or sprout intermittently.
>In the grape-growing industry as a hormone to induce the production of larger bundles and bigger grapes, especially Thompson seedless grapes 1.
>Gibberellins delay fruit maturity and senescence in lemons, oranges and cherries, which helps in storing the fruits.
>Increased yield (larger size) and better shape of grapes is obtained by treating the fruit bunches with Gibberellic Acid (GA3). It induces parthenocarpy in apples, pears, tomatoes and cucumbers.
>Gibberellins treatment helps in breaking dormancy in “seed potatoes” resulting in uniform crop emergence.
>As a growth replicator in the cherry industry.
>Gibberellic Acid (GA3) stimulates phosphate uptake in corn rot cells, potassium in wheat, and sulfate translocation from root to shoot in pea seedlings 1.
>To increase sugar yield in Sugarcane. >To force flowering in Ginseng (Panax ginseng): 1PPM 6BA + 1PPM GA3.1
How To Dissolve Gibberellic Acid (GA3):
Gibberellic Acid (GA3) vs. Various Solvents – Dissolve Results Chart:
Another Mass Spectrum exclusive. In this initial release, basic solubility was the main objective. Full solution boils (i.e. 'Microwave Boil Trick'), or overnight soaks weren't generally attempted. Partial dissolve results data was included as more rigorous pursuits may yield you results. "Melt" results were exclusive to Triacontanol. In each case the melted substance reverted to solid form upon cooling, but its seems possible that applying a secondary solvent to the solution in its hot melted state may enable post-cool suspension in the solution thereby enabling plant bioavailability. "Reaction" means the substance bubbled inside the solvent or similar results (molecular breakdown). This was most common with VOC solvents with heat applied. When heating substances keep an eye for reactions in case we didn't notice them. Beyond all that, results may vary depending on substance batch or other variables. Stay tuned for future updates with more substances, solvents and more thorough methods...
How to Dissolve Gibberellic Acid (GA3) With Only Water:
Chemically speaking, GA3 is perfectly dissolvable in only water, but in practice it isn’t always readily so. In small batch, pre-dilution size test examples results will certainly vary for the lesser. However, especially with good grade product, putting your GA3 directly into the full intended diluted volume of water, and leaving to sit overnight, it should be consider perfectly feasible to achieve. On short order, gradually heat can be expected to increase the dissolution rate.
How to Dissolve Gibberellic Acid (GA3) With Alcohol:
GA3 is best dissolved in high purity Isopropanol (Isopropyl Rubbing Alcohol). You can expect quite immediate results via this method, although heat will certainly expediate results.
Dissolving Gibberellic Acid (GA3) With Sodium Bicarbonate (Baking Soda):
NOTE: Gibberellin A3 will dissolve using Baking Soda, however issues of the base neutralizing and therefore degrading the potency of the (gibberellic) acid are a potential concern. Especially considering this method isn’t necessary. This same issue should be considered when suspending GA3 with other PGR’s into liquid solutions, particularly in terms of mixes that aren’t going to be used in short term. In this vein, diluting several PGR’s at the same time into a large volume of water should bear no immediate effect, however the smaller the volume and longer the time together should increase such concerns. METHOD: A ratio of one scoop of GA3 with two scoops of baking soda (2:1), dissolved via mixing into one teaspoon of water. This mix is then diluted into 2 cups of water to produce (very) roughly a 180 PPM solution which would result in a pH of approximately 8.4.
How to Dissolve Gibberellic Acid (GA3) Into Lanolin Paste:
Gibberellic Acid doesn’t dissolve into Lanolin paste on its own, but the ‘alcohol melt trick’ should work just fine. See the Lanolin Paste page for more info, and the 20mL dilution table below.
How to Dilute & Mix Gibberellic Acid (GA3):
Plant Tissue Culture Stock Solution Example:
Stock solution of Gibberellic Acid (GA3): 1,000 PPM 1. Weigh 0.2g of gibberellic acid and dissolve well with some alcohol drops. Add 200 ml of distilled water. 2. Keep in a conveniently labeled vial at 0°C. The gibberellic acid may be sterilized together with the culture medium: however, the loss of some activity is also possible. One ml of concentrate solution (1,000 ppm) contains 1 ml of gibberellic acid.

Converting Gibberellin A3 (GA3) Between PPM / g/Mol / % / Mol/L / g/L / mg/L / mMol / µMol:
Forchlorfenuron (CPPU) (for seedless grapes)
Sodium Nitrophenolate (Atonik)
NOTE: Treating entire plants with Gibberellic Acid (GA3) can be dangerous, especially via foliar application, and especially during vegetative growth phases. There are safe dose ranges for virtually plants, but overdosing can also eventually cause extreme plant tissue stretching. This can be as extreme as the plant literally falling over under it’s own weight. Mixing gibberellins with both auxins (IAA) and cytokinins (6BA) gives the treatment a synergizing balance and can exceed these limitations (i.e. a hardy ‘stretched out’ plant that is dense and full).
How To Use Gibberellic Acid (GA3):
Gibberellic Acid Seed Sprouting Examples Guide (page 1):
Using Gibberellic Acid To Germinate -Tiny- Seeds:
Many seeds are hopelessly too small to dunk or soak in solution (MSB offers several seeds roughly the size of ‘dust’). Prepare your petri dish or pot with ideal soil media and sprinkle your tiny seeds as expected. Now fill your mini mister spray bottle with desired PPM solution and mist the seeds until wet. Now let sit, or agitate or cover over the seeds (depends on the species you’re working with).
Using Gibberellic Acid To Germinate Coffee Seeds:
GA3 us the most effective PGR for sprouting coffee seeds1. Mix up a 250 PPM Gibberellic Acid plus Fulvic Acid solution in your chosen container. Ensure the liquid is well above the height the seeds will fill once they’re inserted. Insert the seeds and let sit about 4-6 hours. The seeds will swell up to about twice the size above their initial level. As the little root buds form pluck them out with your plastic forceps and plant as usual. This method can easily save several days of germination time.
Using Gibberellic Acid To Produce ‘Feminized Seeds’:
Simply mix up a 100 PPM GA3 solution and spray the target branches of the plant(s) daily for 10 days during flowering to induce male flower formation. Keep this solution refrigerated.
