Super Thrive

[Ray]

The nepenthes study apparently did not take into account the freshness of the material tested, so proves nothing to me. The application rates were pretty strong, too, which may cause issues.

The application of ANY auxin in excessive quantities can be detrimental to the plant. Their relative strengths, or chemical activities vary all over the map, changing the amount needed to go from "beneficial" to "disruptive". 2-, 4-D is an auxin that is used as a weed killer, yet in very low concentrations is used in at least one plant stimulant that I'm aware of.

I'm not sure how you got that from Barry's article. He took cuttings from plants he had available and treated them, and planted them. How much fresher could the cuttings have been? Do I misunderstand what you're suggesting??
Or are you suggesting the SuperThrive used in the experiment wasn't "fresh"?
