Hi,
I wanted to report my experiences growing Psi. semperviva (from Bio). After some problems,
because of a mold in my growing chamber (very annoying!), I managed to get some good cultures
of it. I used rye as a spwan, the usual water/rye ratio and as fruitig substrates
rye and past. straw. It showed that semperviva loves past. straw (I expected this because it
grows in the grasslands). Only after one week it colonized the straw. I cased with 1cm to 2 cm
past. soil (the normal soil for plants you can buy at gardening-shops). Let it colonize the
soil completely (about 4 days). Then I cased again with a thin layer of the same soil, and put
them into a terrarium with a 15 w lamp. I made the same thing for one jar a la Oss & Oeric. After
one week at 24 C and keeping the soil and atmosphere humid, they started to fruit very well. The
The fruits grow really slow, as Heim and Wasson (also Cailleux) wrote in
"Les Champignons Hallucinogenes du Mexique". Now I understand why they called it semperviva
(allways alive). They wrote that it grows even slower than Psi. caerulescens and a fruitbody
can take up to 40 days to mature... It takes also a long time to the spores to reach maturity, and
until now I haven't managed to get a sporulating fruitbody (See problems below), but Heim & Cailleux
wrote that is sporulates heavy.
I had some problems because suddenly the temperature over Germany got over 30 C at day and 20 C at
night (for the last 2 or 3 weeks), and this means that the growing chamber had constantly over 28 C.
It showes that it is too high for the sempervivas, because some of the precious fruitbodies started
to abhort. I wait sincerelly for the announced temp. drop the next week... The best temperature is
about 22 C to 24 C. The rate of pin production to fruitbody growth was perfect. At 28 C to 30 C
almost no pins are produced and some of the fruitbodies started to abhort, although they also grew
faster below 29 C.
The culture that Bio has, although it is the original one from Cailleux (50 years old), is in
perfect state and fruits vigorously (see photos). Probably this species wasn't grown for a long
time and is therefore not degenerated at all. But it wouldn't be wrong to start from spores...
I'll keep on working on that species.

p.d. BTW the ones of you who are interested in growing other species than cubensis, I mean: mexicana,
semperviva, caerulescens and zapotecorum should take a look the the above cited book:
"Les Champignons Hallucinogenes du Mexique", R. Heim, G. Wasson, Editions du Museum National D'Histoire
Naturelle, Paris 1958
I have also an article of Heim & Cailleux:
"Culture pure et obtention semi-industrielle des Agarics hallucinogenes de Mexique" R. Heim, R. Cailleux,
Academie des Sciences, 1957.
I scanned this article an corrected it (a lot of work!). I tried to get it posted in the Shroomery
under "Growing other species" but I didn't get any kind of feedfack of the administrators. I think that it
is a piece of text that this site needs, and I don't understand why these people didn't even write back...
If someone is interested just help me with this guys...
BTW2 has someone noted the erroneous text in "Growing other species" about growing Psi. azurescens
at room temperature? I wrote again the administrators about that and now answer or reaction after 1 month
or so...
