Flowering auto cuttings

Curious...have you ever successfully harvested anything decent from pruned, flowering, autoflower branches...if so, did you just stuff them in a small pot of soil or what? ...for example:

That's the one I just bought.......here's the one he used this should be good to go.
They say "Solubility: Slightly soluble in water, mixable in cold water."

Since the person in the ICMag thread is only using around 10mg in 300ml of water and spraying once a week, "slightly soluble" is probably fine. It also means that it'd be like $10-20 to try, and if it works that would be a lifetime supply. Tempting.

This MSDS for l-triptophan says "Water solubility: No data available". I'm not a chemist, but otherwise it sounds relatively benign in very small quantities? It's probably a good idea to take the same precautions as when mixing & spraying STS, of course.

It might be a good experiment setup to take cutting(s) from an auto around day 10-20, before it starts flowering, start rooting those, and spray weekly. My 24 Carat clone I mentioned earlier didn't start flowering until a few weeks later, as if its hormonal "clock" paused while it was rooting (speculation, but that seems quite possible), but if 1) the cuttings are still vegging ~2 months later, when the original plant is harvested, and 2) cuttings taken from the sprayed-and-held-in-veg plants resume maturing and start flowering within a few weeks of rooting, since they're aren't being sprayed weekly and the l-triptophan should eventually wear off, then that could be really handy.

Using cuttings like that would rule out the "but that wasn't a true Scotsman auto" argument, since it'd be specifically checking that genetically identical cuttings from the same plant that did automatically flower were the ones that stayed in veg, so long as they were being sprayed.

I might try that on the side of my next grow, if I don't have any reg autos going.

Edit: Oh, and later in the ICMag thread the OP refers to it as "tryptophan" with a 'y', just to be sure it's referring to the same thing.

I don't think there will be an issue with smoking plants treated with it. Seems it's metabolized by the plant regardless if fed through soil or foliar.
Here's some info I found "The exogenous application of L-TRP is highly significant for normal plant growth and development. L-tryptophan is applied through foliar spray, seed priming, and soil application. Soil-applied L-TRP is either directly taken up by plants or metabolized to auxin by soil microbiota and then absorbed by plant roots. Similarly, foliar spray and seed priming with L-TRP stimulates auxin synthesis within plants and improves the growth and productivity of agricultural crops. Furthermore, L-TRP contains approximately 14% nitrogen (N) in its composition, which is released upon its metabolism within a plant or in the rhizosphere and plays a role in enhancing crop productivity."
Also we will only be using it in veg anyhow.....any of it still around will have been metabolized.
I found a couple studies about it used in agriculture (which is where that quote came from) to increase yield and 1 that touched on it's use in tobacco but no details.

Ok, got spray bottle and using a guesstimate of 100 ppm. .1 gram in a liter. Need to get a log up for it. I

I have a bag of it....just need to choose a specimen and start spraying. If you start a thread let me know....I'll try to get busy.

Sadly, I'm going to have to shut down all operations.

So sorry friend, i hope everything works out for you.

Is anyone still testing this?

I have to wait for some room to open up to play with it. I've got a bag ready to go though. Haven't seen any updates from other sites playing with it.
