Can we talk rooting hormone?
 

So I was wondering, are all rootinghormones created equal? What are the chemicals inside of it that would alow orchids to root. I have some wilson roots that has 0.4% indole butyric acid, ans .01% 5-ethoxy-3-trichloronethyl-1,2,4-thiadiazole. Is thisthr right mix for orchids because it did seem to do anything....??

I have had good success with KLN solution using 1tsp per gallon of water

I agree with Eyebabe. Roots start forming within or around ten days.

I have used KLN until the fall. It's hard to come by here, so I switched to the Wilson product. The drawback is that the latter increases the TDS by quite a bit. I'm not sure I'll buy it again.

I've used KLN, Dip 'N Grow, and Rootone on a wide range of cuttings, and all three work pretty well. Rootone has the advantage of also cotaining a fungicide, but the other two , since they are liquid solutions, have the advantage of being able to saturate potting media (perlite, etc).

I recommend against using the powders with orchids, as they are 1) insoluble in water, and 2) the hormones are WAY too concentrated, and can damage roots on contact.

The most powerful root-stimulating auxin is the naturally-produced indole acetic acid (IAA). We have to settle for synthetic chemicals that are similar - indole butyric acid (IBA) and naphthalene acetic acid (NAA). Vitamin B1 is also a root-growth stimulant, but to a lesser degree.

Here is a comparison of the various products I've seen, it it suggests that K-L-N and the Hormex product - as they contain all three - are probably the best.
