Can we Do something about this?

This is still stickied on the main page, but there is no link showing how to build a SGFC. Can we do something about this? Do the mods have the ability to edit the main page? It is under Mushroom Info/Growing Mushrooms/General Cultivation/Fruiting Chambers.

Yea those main pages could really use a refreshing update. When I set out wanting to learn I knew to go to shroomery and the most logical choice from the front page splash is "mushroom cultivation". But a lot of the techniques and info in there seem outdated or not concise.

Took me 2 weeks to find the forums lol, then I outgrew all that main page knowledge immediately with more recent teks from dudes like frank.

Actually, just took another browse through there and it's pretty wholesome with a few exceptions (cloning?). For a newbie though I remember feeling a bit overwhelmed by all the different options. Wish there was a better ranking system or something. I feel like PF tek is kind of endorsed as the gateway tek, but seems like a weak choice in comparison to all the other options that are really just as easy with the proper pictorials that are now available. Why even teach SGFC's when we've invented the monotub ¯\_(ツ)_/¯

Well those are two different and viable teks that will vary based on your growing styles. I have been growing for years, but still look to my SGFC for cakes. Sometimes certain strains work better in cake form, (shitake-Enoki).

I still thing someone (cronicr) should be burdened with the task of fixing all of that old info and archiving the crap we don't need.  I can make a list of some of the posts that should be replaced if it makes it easier.

https://www.shroomery.org/5140/What-is-the-point-of-each-step-in-the-recipe


Quoted, with edits.

PLEASE read the getting started Q&A before reading this overview, otherwise it won't make sense!

Using 1/2 pint mason jars.
1/2 pint jars are ideal for the PF-tek for various reasons. First and simply, they have been "tried and true" for quite a long while now. But, there are better answers than that, of course. Glass jars have been used for the (edible) mushroom cultivation for quite a while, for spawn production as well as fruiting. Glass jars are easily sterilized, as they can be safely autoclaved/pressure cooked/boiled without damage to the jar, and while maintaining internal water content of the jars. The 1/2 pint size is ideal as well, since jars can "finish" colonizing within 3 -4 weeks. The reason why this is ideal is because you want the substrate to colonize as quickly as possible - so it can ward off any potential contaminants that may settle in the substrate through a vector you have not discovered, through inadequate sterilization of the substrate, etc.
Using 1 pint jars or larger with the PF-tek means the time to colonize is increased to a point where it is no longer worth it when weighing in the added colonization time as well as the additional risk of potential contamination (in its slower colonization times). It is more generally regarded as "the law of diminishing returns." There have been reports of successful PF-tek recipes used in 1 pint jars, but this is the exception and not the norm. Glass also serves a utilitarian purpose - you are able to see the progression of the mycelial growth (and any possible contaminants as well). Glass cups can also be used, but are not as "plus and play" as mason jars are. They also don't seal as well. But, mason jars can be hard to find in some areas, and their substitution can be necessary for the PF-tek.

Using 1/4 cup BRF, 1/2 cup vermiculite, and 60ml water.
To adequately colonize, mycelia needs food, water, air, and proper temperatures. The brown rice flour is the "food", and the vermiculite ( is also food) makes the entire mixture airy enough for air to reach throughout the substrate (and hence, all the mycelia forming in the middle of the cake that you can't see). So why not up the food, and make colonization quicker? Because, too much food can be a bad thing. The "food" which mycelia loves so much also attracts contaminates, and more food means more of a possibility of contamination. And if mycelia likes air, why not increase the amount of vermiculite in the mix, making it more airy? Once you mix a batch, you will see that the recipe as provided is about as "airy" as vermiculite will get in the mixture. Also, the addition of one element will mean less of another. Water content should also be kept as close to the ratio provided as well. Too much water and too little water both can slow the colonization of substrate to a halt. Plus, too much water will make the mix pasty and muddy - so that the mycelia will have a hard time colonizing through it.

Using a dry vermiculite "seal" on top of the substrate.
The vermiculite seal has 2 purposes.
- It stops airborne contaminants from settling on non colonized substrate
- It also acts to provide some air exchange to the jar.

Air exchange can boost the rate at which mycelia grows, so it is important to have some measure of fresh air passively able to reach the substrate. Also, mycelia and mushrooms create CO2, while using a small amount of O2. Allowing for some gas exchange can help speed colonization. Many people whose PF jars have slowed "flip" their jars, so that the lid is on the bottom - which allows for more air to circulate to the non colonized bottom of the PF cake (the top part generally colonizes more quickly than the bottom).
Bad Info
Lift the jars up from the bottom of the pot.
The heat from the burners on the stovetop transfers directly to the bottom of the pot, which transfers the concentrated heat to whatever is sitting at the bottom of that pot (your jars). Lifting the jars by placing them on the cooking rack that comes with the pressure cooker, or placing a washcloth on the bottom of the pot, will create a more even disbursement of heat. This means the bottom of your jars won't be "cooked" by the heat emanating from the burner. Remember, you're sterilizing by steaming the jars, not by cooking them. A jar whose bottom has been cooked will oftentimes not colonize on the bottom, as the resulting overcooked cake becomes hard and impenetrable for mycelia. Overcooking can also occur if your water level runs too low, so be sure to maintain water in the pot for the entire sterilization time. AND DO NOT ADD COLD WATER TO THE BOILING JARS, otherwise they will crack (explode in your face) and be unusable.


This as a sample of what I am talking about, I understand the need to keep the original posts the way they are because the original users posted them. I think this post is like from 2000. We need to get the info updated.

https://www.shroomery.org/5141/Why-do-we-boil-the-jars-of-substrate
(quoted) Edits
We boil the jars in order to sterilize them in order to destroy all forms of life in the jars. (molds and bacteria, spores and bacterial endosporse). This is done, so we can inoculate the now sterile substrate with the desired fungus.

These organisms which live in the soil, in water, and air etc. can invade and digest a food source like the one we are providing with the PF-tek recipe. This we call contamination.

Boiling water reaches a temperature of 212° F, which is adequate to kill molds and spores which may reside in the water, vermiculite and the brown rice flour. (Sterilization happens when water is boiled at 250 F. The water needs to be pressurized to reach that temperature. If water is heated under pressure it will reach 250 F @ 15PSI. Maintaining this temperature and pressure will allow the proper sterilization of everything inside the jars. Boiling Jars works for PF tek, but is not sterilizing them.)

The main page is were I started for my first grow I used info from there for months before I ever registered as a member and hit the boards. There is definitely some outdated shit on there. I dried out many fruits without a dehydrator because the main page told me heat exposure would lower my potency.

Quote Edit

In the open air, you should take care to be as clean as possible, as the air itself contains contaminants which would love to colonize your lovely PF substrate and kick your mycelia's ass.





In the open air, you should take care to be as clean as possible, as the air itself contains contaminants which would love to colonize your lovely PF substrate and kick your mycelia's ass. So, spray an anti -bacterial spray in the air around you, work as quickly and efficiently as possible, and be sure the only thing that touches the needle is the substrate, (make sure to flame sanitize your needle and do not wipe with alcohol after) which is sterile (if your procedures are correct). You do face the off chance of a contaminant landing on the needle, which is then introduced to the sterilized substrate. .When using a sealed gloveboxSAB or flow hood, there is minimal to no chance of contamination through inoculation procedures. Basically, the more time and effort you put into keeping your procedure sterile, the less chance you will encounter of contamination.

****NOTE**** Open air inoculation is never recommended. Spend the time to make yourself a gloveboxSAB and follow sterile technique. You will have much better results.

I just did the work on a few posts. We need a MOD to cut and paste I guess.
