the silvery one on the left is cytokinins (kinetin hormone)
indoleacetic acid (another hormone) is the same as the kinetin packaging and both need
indolebutyric acid (another hormone) the same, needs a solvent because it comes in concentrated powder.
these 3 need solvents because they are not water-soluble.
the one in the right image in Chinese is paclobutrazol (hormone)
I bought the gibberellins already liquid.
acetylsalicylic acid (another hormone), aspirin is used, of the Bayer brand, since aspirin is that, acetylsalicylic acid, and yes, it is a plant hormone (in fact, it is extracted from willow tree bark)
if what you want is to buy, you can look on aliexpress, amazon, or regional agricultural stores (because this is used in all crops) the thing is that for the hormone preparations they sell, they usually ask for an agricultural license, if you don’t have one, which would be normal, you can buy online and make your own preparations.
indoleacetic acid is auxin, it is used for root and vegetative growth, it is very effective (these are of the same group or grade as homemade lentil auxins, they have the same effect, but this way you control the exact dose and it doesn’t have traces of other organic matter like when we use lentils)
indolebutyric acid is used for rooting and germination, the famous brand CLONEX, its main active ingredient is this hormone, so you can save a lot of money by buying it, its strongest point is for making cuttings.
acetylsalicylic acid (aspirins) is great for dealing with plant stress, it revitalizes them, its use as a stress reliever is very noticeable, the plant generates this hormone when attacked by mammals and insects to deal with the stress of the damage produced by bites, a curious fact is that the plant knows it is being eaten by an animal or an insect by the animals’ saliva when biting, then is when it generates this hormone, I use it after pruning and it is very noticeable.
paclobutrazol and cytokinins act very similarly, they inhibit the production of gibberellins (the hormones that make plants stretch) making the plant shorter, with more compact nodes.
and gibberellins, the opposite of the last two, are responsible for the stretching and elongation of stems.
the last 3 are quite difficult to use, as there are no studies on cannabis, there are on tomatoes, peppers, strawberries, fruit trees, etc., etc. but the doses and application times vary greatly, furthermore, regardless of which of the hormones is being discussed, beyond a certain amount they produce the opposite effect to the desired one.
so… for the last 3 hormones, you have to find the exact dose and timing, and even having them, this would only be valid for that specific strain/plant variation, I am experimenting to see to what extent it could be profitable
