Mushroom Teks on the Nexus
A while back SWIM searched the nexus in an attempt to find a really easy and straight forward mushroom growing tek, but only came across ones that were either confusing/complicated or outdated and used unnecessary steps.
After doing lots of research and about two years of mushroom growing experience and testing, SWIM thinks he found the best tek and is now, finally, ready to share it with others.
In SWIM's opinion, mushroom cultivation (if done respectfully) can be a very fun hobby that keeps the mind and body in sync. It can be one of the best experiences of one's life, both eye opening and enjoyable. SWIM wants to introduce others into the hobby and help others experience this.
The First StepsFirst, we need to buy all the supplies needed, including the spores.
There are plenty of vendors for spores.
Also, there are plenty of vendors to buy supplies from, both online and at your local garden and hardware stores.
In the past two years, SWIM has bought ready-to-grow mushroom kits that were pretty darn expensive (and didn't work) and some very cheap mushroom supplies [do it yourself grow] (that worked very well).
In the end, the best, most cost effective way is to buy the individual supplies needed or supply kits, not the ready-to-grow-out-of-box kits.
Besides, growing them step-by-step all by yourself is so much more fun and very rewarding.
Now, SWIM is not one to drive all over town to get what he needs, so SWIM searched for mushroom cultivation supplies online. If you can get everything from one place the shipping shouldn't be that bad.
Two Online VendorsMyco Supply - SWIM has not tried this vendor but it has a lot of products, which is very good for the more advanced mycologist. It is decently priced for some things, but difficult to navigate in order to find what SWIM needed. This may be good for some people. SWIM's list of supplies for this TEK are below.
MushBox - In SWIM's opinion, this site is decently priced for its non-sterilized supplies but a little over-priced for its pre-sterilized supplies and liquid culture. SWIM never tried this site (firstly because he found a better one and secondly) because the step-by-step kits (do it yourself supplies) were overpriced and included unnecessary equipment. Also, navigating the site, again, was difficult. However, some may like this site, SWIM's list of supplies for this TEK are below.
The following supplies are required to make one spawn bag.
SuppliesSpores (preferably in a syringe).
Approximately 1oz (~29ml's) of Liquid Culture
1 Sterile syringe with needle
2 Spawn bags. 1 preferably with injector point and 1 without.
3 cups Vermiculite
1 cup Whole Grain Brown Rice Flour
1 cup Water
~2 cups Perlite
Stove-top burner/hotplate and large cooking-pot for sterilization of soil
Scotch tape
Alcohol swabs and hand sanitizer
Lysol disinfectant spray is good to have around
The TEK
Using The Above Supplies
First and foremost, SWIM would like to note that, if done correctly, this TEK can make one spawn bag starting from spores and ending with a yield of approximately 300 fresh grams in only about 5-7 weeks. This of course is partly due to much faster and stronger mycelium growth (on the substrate) when prepared firstly in liquid culture. Thank you everyone for helping this TEK be born. And enjoy the edible delicious mushrooms.
Step one: Preparing Liquid Culture - Obtain spore syringe and approximately 1-2oz's of sterile liquid culture. Spray room with Lysol. Wipe injector point with alcohol swab. Try best not to breath on work area. Have no air circulation. Inject desired amount of spores into culture, just a few ml's is needed.
Leave liquid culture in a dark warm place (~80 F) for 7-21 days. Shake 1-2 times a day. When 2/3 of liquid has white growth SWIY can move onto step two. This is a key point; the more mycelium growth in the liquid culture the stronger and better the mycelium growth will be in the next stage. Also, it is important to not let the mycelium in the liquid culture exhaust the sugars and grow weak. Use them before two or three weeks of growth in the LC or refrigerate.
Compare with this image to make sure liquid culture isn't contaminated.
Here is an image from the start of SWIM's liquid culture growth.
Step two: Making and sterilizing substrate - Place two cups of vermiculite and one cup brown rice flour in a bowl.
Mix well.
Add 3/4th cup of water. Mix well.
Place in spawn bag with injector point.
Tape up spawn bag.
Place in pot, suspended above water using small glass jars or the like.
Bring water to boil just below substrate and steam covered for 1.5 hours. When finished, set aside for four hours or until cooled, without removing the lid (very important).
Step three: Inoculating substrate with Liquid Culture - Sterilize the room using Lysol. Get un-used sterile syringe and needle as well as alcohol swabs. Sanitize hands with hand sanitizer. Carefully remove spawn bag from pot, avoid air circulation and breathing directly on project. Use alcohol swab on liquid culture injector point and on the spawn bag injector point. Open syringe and pull liquid culture into syringe.
Inject into spawn bag. Use 1oz of the liquid culture. Make sure to turn the substrate over to get the underside. Use 1/2oz of liquid culture on each side.
This is the bottom of SWIM's substrate. SWIM does the bottom first and then turns it over carefully to finish off the top. Note that SWIM forgot to use spawn bag with injector point. opps, oh well. If SWIY isn't using spawn bags with injector point, remember to tape up needle hole afterwards(very important).
And this is the top of SWIM's substrate being injected with liquid culture (aka, inoculation).
Place bag away from light in a warm place for 14 days (~80 F). Let no air exchange happen during this stage.
Step four: Checking Mycelium Growth - After 2-3 weeks, check spawn bag. If white mycelium growth has completely surrounded the soil then it is ready (it is completely
colonized). If not, let it sit longer. If any bacteria growth is not white in color, it has been contaminated and is no longer good (not the case with cobweb mold [which is white]). DO NOT OPEN. Throw this away, it is no good. Start over and try again with more awareness to sterility. Check this link to be sure.
ShroomeryHere is a fully colonized spawn bag.
Step Five: Prepare To FruitBelow is a fully colonized substrate from this tek.
When it looks mostly colonized around 2-4 weeks it should be ready for the next stage.
This image is after 4 weeks using this tek. Remember to sterilize the room and stop all air movement before cutting open the bag.
Cut about 2-3 centimeters above the substrate as shown below.
It may not look fully colonized but it certainly is, the mycelium has grown deep within the substrate even though it does not show up on this image.
Next we want to make up some vermiculite and coir coir casing layer. Use 1 to 1 ratio of each and add just enough distilled water before it becomes wet and dripping. Microwave in glass jar for ten minutes. Let cool over night with lid securely tightened.
Lightly spread onto the colonized substrate, make sure it is evenly spread (very important for even pin set).
Mix 2 cups Perlite with .5-1 cup of water and lay evenly into a new spawn bag (without injector port).
Place substrate (with plastic still on it) into the new spawn bag with Perlite in it.
Mist with a very fine water bottle and seal with a paper clip. Let sit for 3 days in darkness without fresh air in order to colonize the casing layer a little.
Step six: FruitingNow you need to introduce light, and fresh air.
Mist carefully with a fine mister 3-4 times a day. Rotate between 13 hours of light and 11 hours of dark.
Lastly, make sure the temperature stays in the high 70's *F range. (Check what strain you have and google its fruiting conditions for optimum success)
Be very patient, it may take two weeks before pins show up.
In the mean time, enjoy some pictures from this tek.
Soon your success will yield many mushrooms.

All of these pins are growing off of the side of the plastic. Interesting!
Day 17 Note that SWIM's FOAF did not use a casing layer in a small section of the substrate to see if it would pin well. It did not pin well at all. The pin circled in red on the left is growing very abnormally and the red circle on the right is only perlite, not hyphal knots. Lastly, the two pins at the top of the image are indeed growing from the substrate and not the plastic

Unfortunately, SWIMs FOAF forgot to take images of the whole casing of mushrooms before harvesting.
Below are the mushrooms already picked off the casing and then the final amount air drying.
Step seven: Picking - After veil breaks, twist mushrooms off substrate carefully and repeat step six. This tek usually has 2-3 flushes.
Here is a mushrooms with the veil broken.
Harvest Total weight wet equals 103.3 grams. About ten grams dry for first flush.
Step eight: Air Dry - Take fresh mushrooms and place under fan for 48 hours or until mostly dry.
103 Grams wet.
Step nine: Descant Drying - After Air Drying, place the mushrooms into a descant chamber. Here is an easy way to make one.
First buy this at a hardware store. It's a refillable descant thingy
(moisture absorber).
Next you'll want to get a medium to large Tupperware container and cheesecloth.
Tape the cheesecloth into it so it hangs down a little bit for the mushrooms to sit in.
Below is an image to show the height of the Tupperware.
Next, cut a hole in the bottom of the Tupperware so that the descant thingy fits snug into it(Note that the descant thingy needs to go through the top of the Tupperware down through the hole [so you'll need to remove the cheesecloth when necessary]). Because the descant thingy gets wider as you near the top of it, it nicely squeezes into the Tupperware. We want an air tight seal.
And your done. Put the
Air Dried(very important: must be air dried first or mushrooms will spoil) mushrooms into the Tupperware on top of the cheese cloth and place the lid tightly on top to seal out other moisture. In 24 hours, the mushrooms will be cracker dry and ready to go.
A few lonely mushrooms drying.
Step ten: Enjoying - Eat and Enjoy.
Thank you Nexus and others.
