So I got P. Stamets: Growing Gourmet and Medicinial Mushrooms.... and uhhh

Well I got the book strictly to start expanding my knowledge in other growing parameters of mushrooms and to experiment myself. As I was reading through the book, I was looking to prepare substrate using sawdust, woodchips, and bran. In the book it is information overload. I'm not a commercial grower, but it seems more for the likes of hobbyist doing commercial grow(maybe eventually i will get to that level). So i look at how to prepare the substrate, and I'm hoping someone can go into detail on how to check if my substrate is "too wet" or "too dry". It says in the book that it should be 60-65% wet, and that if I forcefully squeeze the substrate and water stream comes down, it is too wet. Is this true? Because I've read forums that its okay to have a stream of water when squeezed. Also, I'm looking up teks and many of teks on this forum are suggesting to do PASTEURIZATION, but P. Stamets book is advising the grower to STERILIZE the substrate. Are both pasteurization and STERILIZATION okay?
One more clarification, P. Stamets was also talking about "exploding" if there is too much air in the bag. Can anyone explain how this works of it and how to avoid it? Thanks alot guys.

First off, you do not want any stream of water pouring from your sawdust, you are way better off more dry than wet. Now you can pastuerize if you don't supplement your sawdust, some get away with it, but not for the new grower especially if you are supplementing at 20%. As for the exploding of the bags, It can happen, especially if you seal your bags before sterilizing, it happens at the end of the cycle when the pressure cooker has lost pressure faster than the bags which are still holding pressure, I have only had it happen a few times in a super loaded cycle but I use tyvec sleeves in my bags for sterilizing.

Well I plan on adding oats for supplement, so sterilization is key for me?
Okay, so i purchased the bags with the micron filter, should i worry about the bag exploding? Should also, should i tape up the micron filter? or just avoid it getting wet by putting aluminum foil over it? I'm thinking of the same concept as putting foil over the WBS grain jars to prevent from excess water getting into the jar.

Theres a few different ways to go about it, I personally use a tyvec sleeve slipped into the bag and then fold it over a few times, you can find a video by RR to show you visually, it's in the video on making sawdust. On the very top place a heavy plate so the bags don't unfold and clog the PC vent. The bags will create a seal itself, the tyvec is for the space between the gussets which is the place that dirty could come through.

The part with the tyvec is about 4-5 minutes into it.

Thanks this video helped me a bunch !!! instead of using tyvec sleeves i'm most likely going to use tyvec paper, since it's for afforable and easier to get for me
Well i don't have full on woodchips, i got a mixture of sawdust, chips, and shavings. I read in the book that it may be inconsistent but I guess with that being all i got, I am just going to try it and with a small batch and see the results.

Hey captaino, typically straw is pasteurized and wood-based or some other ag waste substrate supplemented with some sort of bran or other source of N is sterilized. I just load the bags, seal them and roll them up with patch on the inside of the roll. So far I haven't had any issues. I line my pc with an old t-shirt so the bags don't come into contact with the metal. Also, if you let the pc cool completely the bags won't be puffed up. Don't get overwhelmed by the amount of info in the book or on the website, just keep thinking, experimenting, researching and having fun!

Thanks for the info and advice I will definitely take that advice! I just like to start somewhere with a good grasp of basic info just so i'm not wasting time and know that i am at least on the right track. So thanks for the advice and encouragement =]

Get a tyvec paint suit at homedepot, you can make a ton of strips for you bags with one. Hey Colorado, why do you not let the bags touch the sides if the PC?

Hey MM, prolly just paranoid but I read somewhere on here that the bags can melt if they're in contact with the pc. My pc has the false bottom that doesn't come out with the jar holder wire thingies which could maybe melt a hole if in contact with a bag? I'm too cheap to run them without some kind of liner to find out for sure.

I run an AA941 and 921, never had a bag melt or heard of it, most of the time my bags are packed tightly in too. What kind of PC do you have? Though doubt I there is too much of a difference on the insides, someone correct me if I'm wrong but the only way the bags would melt is if you run out of water.

Hey MM, yeah, I believe the guy had run the pc dry in the thread I was reading. I'll give it a shot. Hopefully I'll get my pasteurization drum converted to a bag steamer like Gr0wer and Weetsie have built....pc'n bags is time consuming.

Yeah it sucks! I'm in the middle of building a steamer as well, I still need to get the SS float and element protector and it will be done!!!!

So I sterilized the supplemented substrate and inoculated them with grain spawn. Hopefully everything goes well!

Can someone lead me in the right direction on information of liquid culture?
I have a couple of liquid cultures i've had sitting in a cabinet for a couple of months, I wondering how long do they usually last for. I used honey and water mixture. Also, I checked up on my stropharia rugosoannulata and it looks like a layer of mycelium is growing at the top.. is that normal or should i dump it and start a new batch? What colors do i look for for any contamination? I have a couple of brownish orange (mycelium?) growing in some as well. I guess i'm suppose to shake it everyday.. I totally forgot. haha

Hey Cap, I'd say, with some exceptions, anything but white at the culture stage is gonna be funk. You might look into working with agar media and grain to grain as it's much easier to spot contamination and ditch LC altogether. Just my 2¢

Well, just ran 2 bags in the pc and on of the bags melted to the fixed basket inside. Back to wrapping bags in an old t-shirt.

Not sure I saw you mention earlier but what kind of bags are you using?

Hey Shirak, I got them off eBay. They're standard filter patch bags. I'm pretty sure the issue is the fixed basket thing which may have come out at one point but has long since fused to the pc (it's old). It has wire handles that may have been used to remove the basket. If these touch the bag just right they melt it. No biggie...I'll just wrap them until I can get a larger sterilizer built.

huh really weird that the wire could get hot enough if there is water around it. You could try raising the water level? The bags don't mind sitting in some water.
