does the flush number affect potency?
    #633903 - 05/17/02 03:49 AM (21 years, 6 months ago)

say you have your harvest from your first flush, and third flush- will the first be more potent than the 3rd? just wondering because it seems like the first ones i pick always seem to hit me a lot harder.

house is a spiritual thing

Read Bigwood and Beugs paper on the flushes of P. cubensis. There are differences in the potency between the four to five flushes of shrooms. It was posted on some of the web-sites a while back.. Check with Hippie3 at the mycotopia.net website for this paper. He might know where it is.


See below>


The Analysis of Psilocybin and Psilocine
Michael W. Beug and Jeremy Bigwood

The quantity of psilocybine and psilocine in certain species of mushrooms (notably some Psilocybe and Panaeolus species) is amazingly high, sometimes well in access of 1% dry weight, and typically 0.2 t0 1%. IT is interesting to speculate how and why the mushroom plant expends so much biosynthetic energy to produce a compound of no known obvious use to the plant itself. From the standpoint of the mushroom user, the high level of psilocybine and psilocine means that the mushrooms are potent in crude form without prior isolation or concentration of the active ingredients.

From the standpoint of the chemist, the high levels similarly means that psilocybine and psilocine can be analysed in the crude extracts, without lengthy (and probably expensive) prior separation and concentration. This also means that forensic chemists can quickly and cheaply do the analysis for the prosecution (or defense) in a court case. The picture becomes clouded (beyond the legal implications) when the chemical analyses are complete. A given sample of one known hallucinogenic species is often found to be over ten times as potent as a given sample of another hallucinogenic species. To put it mildly, this could lead to a real surprise for the unwary user. So it would seem that the answer is to discover the potency of one species compared to another. Even There, the answer is disturbing because when samples of the same species from different areas are compared, the amounts of psilocybine and psilocine are found to differ by a factor of 4 or more (Psilocybine and psilocine are sometimes absent altogether in a normally active species). Maybe the answer is to stick to one patch of mushrooms. It turns out that here, too, problems arise. When mushrooms from one patch are sampled from time to time, the levels of psilocybine and psilocine are still found to vary by about a factor of 4 (sometimes more). Well, maybe you can rely on cultivated hallucinogenic species like Psilocybe cubensis (Earle) Singer.

When analyzing samples from various sources we found 6-fold variations among the street samples, with some species only one-tenth as potent to some of our cultivated material. One might at this point be temped to conclude that cultivation of your own strain might be the answer. Working with reproducibly grown mushrooms of a single strain, we found variations of nearly threefold from one flush to another and from one culture to the next. The only consistent trend we found was that the first flush, while it often contained high levels of psilocybine, almost never contained any psilocine. The same was found to be true in mushrooms cultivated by others. However, there was no reproducible trend in total amount (Psilocybine and psilocine) from flush to flush. The inescapable conclusion is that when dealing with wild mushrooms or cultivated mushrooms it is not possible to predict that psilocybine and psilocine level with any accuracy. A user of mushrooms is thus hard pressed to predict dosage.



Well I was referring to a more recent paper by ott beug and biugwood, not the above paper which was written earlier for a mushroom conference.
