Rooting Hormone?

[ces797]

Other than Superthrive is rooting hormone available in liquid state? I've only seen powder form. Would it be possible to mix in the powder form with the water?

What if I have a root stimulator that has a surfactant (soil penetrant). It's active ingredient is Indole-3-butyric acid.

IBA and NAA are the two most common synthetic rooting hormones on the market, but in order for them to have a practical use in orchid culture, they must be water soluble, which they are mostly not in their pure form, requiring that they be compounded with other cationic species to make soluble salts. That is why you will see what appear to be traces of fertilizer on some labels - K-L-N, for example, is listed as a 0.009-0.011-0.006 fertilizer - insignificant, but required by some state laws.

With-, or without a surfactant, a rooting hormone in powder form will not be good for orchids, AND, they tend to be in a lot stronger concentration than the liquids, which can be damaging.

This is fert-i-lom (sp), and is a liquid. I'm frustrated that it says nothing about water solubility on it. Is it still safe to use on the orchids if I dilute it significantly?

What is the hormone concentration?

It's a 4-10-3 fertilizer as well, the Nitrogen is ammoniacal.

The IBA concentration is .0004%

The surfactant is 1%

it recommends 3 1/2 tbsp/ 1 gal, and says it is safe for roses.

I'd say it would be safe to use, but I would absolutely not use it at the concentration they recommend! It is primarily a fertilizer, and that application rate will give you 550 ppm N!!! I would stick to less than 1 tablespoon per gallon, as 1 Tbsp/gal is about 160 ppm N.

I was wondering about that after I used the calculator on your site!
Thank you so much Ray, I really appreciate your help.

Out of curiosity, what is the ideal PPM range people shoot for on a weekly basis? Currently my plants get about 150 per week.
