|
What do we need to grow magic mushrooms? Well here is a list of all the
|
|
necessary items to grow your own:
|
|
|
|
1) Fertile Psilocybe cubensis spores.
|
|
2) About twenty sterile plastic petri plates.
|
|
3) Malt-Agar medium.
|
|
4) Alcohol lamp containing methyl or grain alcohol.(Alcohol wipes do fine as
|
|
well.)
|
|
5) Inoculating loop.(Wire bent in a loop with a handle is good.)
|
|
6) Agar knife.
|
|
7) Test tubes. Filled one-third with grain ( birdseed ) and plugged with
|
|
cotton.
|
|
8) Two lbs. of compost. It should be cow manure, preferably leached, although
|
|
you can also use natural wood-based composts such as Douglas Fir mulch or
|
|
pine mulch.
|
|
9) Casing soil. It should be a bag of peat moss mixed with a cup of lime.
|
|
10) A big can of Lysol or other disenfectant.
|
|
11) A glass container at least 10 ounces or 300 ml which can be plugged with
|
|
cotton, capped with aluminum foil and pressure-cooked.
|
|
12) Pressure cooker. The smallest size, 10 1/2 liquid quarts, can be used,
|
|
and it should have a pressure gauge.
|
|
|
|
Almost all of these items can be ordered by these companies:

|
(: MATERIAL PREPARATION AND WORK SPACE :)
|
|
|
|
To begin, start with a clean table top, plastic or formica, in an area free
|
|
from drafts. Wipe the table with Lysol, and when doing transfer work, cover
|
|
your nose and mouth with either a hankerchief or a surgical mask so you don't
|
|
breathe germs onto the sterile media.
|
|
|
|
To insure sterile conditions, you may wish to use a transfer chanber. A
|
|
transfer chanber can either be purchased or constructed out of simple
|
|
materials, plywood, glass or plastic for the top, and a cloth entryway. If
|
|
cardboard is used, line the inside with aluminum foil to protect the chamber
|
|
from burning when you use the alcohol lamp. The box need not be air tight,
|
|
the idea is to prevent contamination from drafts and breathing on the media.
|
|
The inside of the box should be wiped down with Lysol and your hands shown be
|
|
cleaned with Lysol before putting them into the box. Gloves may be used if
|
|
your hands are sensitive to strong chemicals.
|
|
|
|
|
|
(: STERILIZING MALT MEDIUM AND POURING :)
|
|
|
|
Next, we prepare the medium, or food substances, on which the mycelium will
|
|
grow. Place the malt-agar medium into your flask or bottle and add eight
|
|
ounces, or 250 ml of water. Stir or shake slightly. Then plug the flask or
|
|
bottle with cotton and cap it with a piece of aluminum foil.
|
|
|
|
Now put the flask into the pressure cooker on the rack or trivet provided with
|
|
the cooker. Turn on the heat and bring the cooker up to fifteen pounds. Keep
|
|
it there for twenty to twenty-five minutes. Monitor the process in order to
|
|
keep the cooker at the proper pressure and to make sure you don't over-heat.
|
|
After twenty minutes, turn the heat off and let it cool down to zero pressure
|
|
naturally. Do not release the pressure.
|
|
|
|
Wipe down your transfer area, either the table or chamber, and place the petri
|
|
plates inside your chamber or on your table. Using a mitten, take your flask
|
|
out of the cooker and place it next to the petri plates. Throw away the
|
|
aluminum foil. You are now ready to pour the medium into the plates.
|
|
|
|
Remove the cotton and grasp the flask with your mittened right hand. With
|
|
your left hand, take a petri plate and hold it slightly open. Pour the medium
|
|
into the plate, just covering the bottom surface and then close the plate.
|
|
Repeat the process for nine more plates and set aside to cool. Before you go
|
|
onto the next step, you may want to let the plates sit for a few days to check
|
|
for contamination. If, after two days, you notice anything other than
|
|
tannish-brown medium in the plate, discard that plate. Now you are ready to
|
|
streak the plates with spores.
|
|
|
|
(: SPORE STREAKING :)
|
|
|
|
To keep spores fertile they should be stored in a cool, dry, dark place. The
|
|
spores should remain viable for at least six month, perhaps indefinitely.
|
|
|
|
Wipe your table or transfer chamber with Lysol; also wipe your hands. You
|
|
should have the petri dishes with cooled medium inside the area. Light the
|
|
alcohol lamp, and have your inoculating tool bent into a loop and ready to use.
|
|
Remove the piece of paper containing spores and place it face up on the table.
|
|
|
|
Open one of the petri plates, holding the top right over the medium to prevent
|
|
contamination. Flame the inoculating loop, then cool it by placing it in one
|
|
part of the medium on the plate. Scrape some spores off the paper with your
|
|
loop and smear them in an 'S' configuration onto the medium in your petri
|
|
plate. Immediately close the plate and proceed to the next one. I recommend
|
|
that you streak two to four plates. You want to save the rest for two reasons:
|
|
|
|
1) The germination might not take.
|
|
|
|
2) The plates might be contaminated.
|
|
|
|
If this happens, repeat the entire process.
|
|
|
|
(: INCUBATION AND IDENTIFICATION OF CULTURES :)
|
|
|
|
Set aside your inoculated plates in a warm area, approximately 70 to 75
|
|
degrees F. A heating pad or light is useful for maintaining this temperature.
|
|
|
|
In ten days to two weeks, you should notice a snow-white, fluffy, cottony
|
|
growth on your plates. This is the psilocybe mycelia. In a few more days, it
|
|
should develop long threads, ropey fibres reaching out to the outside of the
|
|
plate. At the end of two to three weeks, the entire plate should be covered
|
|
with this pure-white mass.
|
|
|
|
Chances are you will have some contamination also. Do not be discouraged;
|
|
it's a common hazard and the reason you work with more than one petri dish.
|
|
Contamination takes many forms. The two most common are penicillium and
|
|
neurospora, or bread mold. Pencillium will appear as a dark green spot, the
|
|
kind you see on stale bread, and it can be dealt with in two ways:
|
|
|
|
1) If the white mycelia overgrows it, you can flame your knife
|
|
and cut out the contaminated area.
|
|
|
|
2) Or, if the penicillium overruns your plate, it is wise to
|
|
discard the entire petri dish.
|
|
|
|
Neurospora is a grey-white hairy mass, darker than the psilocybe mycelia, of a
|
|
type you also see on bread. This is a very strong fungus, if discovered
|
|
discard the entire dish.
|
|
|
|
Other contaminants are dealt with in the same way, and if you wish to identify
|
|
them we suggest you check the photographs in 'Growing Wild Mushrooms' by Bob
|
|
Harris.
|
|
|
|
(: TRANSFER AND ISOLATION OF PURE CULTURE :)
|
|
|
|
Again wipe down your transfer area, clean your hands, and light your alcohol
|
|
lanp. On the table you should have your petri plates grown out with mycelia
|
|
and the other six plates which contain only media. Flame the knife, cool it
|
|
in the unused media, and cut out a small section of mycelia. Stab the small
|
|
piece of mycelia and place it in the middle of a plate containing only growing
|
|
media and cover the dish quickly.
|
|
|
|
Transfer these sections into three more dishes, and incubate again as
|
|
indicated in the previous section. Allow a few weeks to grow out and you are
|
|
ready to transfer to the spawn. If you have any difficulty or contamination,
|
|
remember you have twelve dishes left that you haven't streaked yet, so if you
|
|
have problems repeat the streaking process and begin again.
|
|
|
|
If you have gotten this far, you isolated a pure culture, one that will be
|
|
easy to maintain and making it possible to not having to return to spores for
|
|
several generations. You are now ready to start the spawn.
|
|
|
|
(: PREPARATION OF SPAWN :)
|
|
|
|
Our spawn medium can be rye or other grains, but I use a combination of milo
|
|
and millet, commonly used in bird seed.
|
|
|
|
Make sure your test tube is filled with one third grain. Then add half again
|
|
an amount of water. Put the cotton back in the test tube, cover it with
|
|
aluminum foil and place it on a trivet in your pressure cooker. Follow the
|
|
cooking procedure as indicated in the section sterilizing malt medium.
|
|
|
|
Take the test tube out of the cooker, shake up the grain inside and put it
|
|
aside to cool. Transfer the mycelium from the petri plate to the grain in the
|
|
same manner as indicated in the previous section. Set aside the test tubes at
|
|
70 to 75 degrees F. to incubate. After three to four days, shake up the grain
|
|
in the tube and allow another seven or eight days for the mycelium to spread
|
|
through the grain. Once the grain is completely run through with fluffy,
|
|
white mycelium, you are ready to use it to innoculate the compost. If you
|
|
notice anything that looks like contamination, begin again by inoculating
|
|
another test tube.
|
|
|
|
(: INOCULATION AND INCUBATION OF COMPOST :)
|
|
|
|
Break up the grain in the test tube eith by shaking it or using chopsticks,
|
|
and spread the mixture into the compost. You can inoculate and incubate the
|
|
compost in a flower pot or plastic container.
|
|
|
|
An excellent method is to put the compost in a tray and place it in a fish
|
|
tank with a loose lid. For moisture and humidity control, put wet cat litter
|
|
in the bottom of the tank. The compost should be slightly wet, so that you
|
|
can squeeze it in your hands and it will leave a faint mark on your hands. If
|
|
you squeeze out water it is too wet and if you can't feel or see a mark on
|
|
your hands it is too dry. In a week to ten days, the compost should be
|
|
completely run through, full white, with mycelia. Maintain a coolish
|
|
temperature, perhaps between 65 and 75 degrees F. for this process. We keep
|
|
it this cool because the mycelia generates a lot of heat when it grows out and
|
|
heat will kill it. You know it's too warm when you notice a yellowing of the
|
|
mycelia and a yellow liquid around and through the growing media. That means
|
|
it's dying and you might have to begin again.
|
|
|
|
Some misting might be required to maintain moisture. Once the mycelia is run
|
|
through, spread a one-half to one inch layer of casing soil on top of the
|
|
compost. This will induce fruiting.
|
|
|
|
(: FRUITING AND PICKING :)
|
|
|
|
Place the compost/casing mixture in a closet free from drafts but allowing
|
|
some circulation. Put them under a normal flourescent light and leave on a
|
|
typical day/night schedule. The lights can be left on continually although I
|
|
don't recommend it, nor do I recommend incandescent lights.
|
|
|
|
Maintain a 65 to 75 degree F. temperature and keep the casing soil slightly
|
|
moist as noted earlier with the compost. In a week to ten days, tiny pinheads
|
|
will appear on the casing soil and will soon begin to sprout mushrooms. At
|
|
this point. the mushrooms will grow rapidly, just as it is not unusual to see
|
|
a fully-sprouted mushroom on your lawn almost overnight.
|
|
|
|
Wait until the caps break the veil and then pick, scooping them out from the
|
|
bottom with a chopstick. You can wait until the cap flattens out and the
|
|
mushroom gets bigger, but at this point the mushrooms will begin throwing
|
|
spores on the growing surface and this may inhibit later flushes. Mushrooms
|
|
should sprout for about four or five days in abundance, then over the next
|
|
week or ten days you will notice two to four more flushes. The mushrooms in
|
|
these later flushes will be smaller and less abundant. At this point your
|
|
growing medium is exhausted.
|
|
|
|
(: MAINTAINING THE CULTURE :)
|
|
|
|
You now have a basket of mushrooms and a pure culture in your petri dishes
|
|
with which to grow again. Or, if you have lost the culture, you can clone the
|
|
mushrooms you have by taking flesh from it. This process is described in
|
|
'Growing Wild Mushrooms' by Bob Harris.
|
|
|
|
|
|
|
|
I hope you all have an electric ride and the walls melt like butter in a
|
|
microwave with your home-grown mushrooms.
