Thanks Ashley! You don’t miss one detail and your videos are so easy to follow and learn from
You are so welcome! Thank you!
Easy to follow too. Thanks for sharing.
Glad it was helpful!
i have watched this video about 10 or 12 times now just to hear you say "A Bomb" LOL
it also teaches my children about the importance of safety while using pressure cookers
Yes! Exactly why I said that! I wanted people to know that it’s dangerous and you need to be careful! Thank you!
Thank you! Your vids are always such a help!
Thank you!
Another great video. Thanks for the info
Thank you!
If you wanna try an experiment, try no pasteurize or no sterilize for only one of your bags, just to see what happens?
And compare
Awesome,thanks so much
The way she said bomb 💣 crack tf up omg
NIce, my wood lovers are giving me trouble. A hint someone gave to me about the straw is to take a weed whacker to it so it gets cut into small pieces. The sharing of stuff like that is what is cool about the community.
Really interesting to see the different types of bulk substrates that can be used. That colonized in the monotub quickly. Will you use a casing layer?
I will use a casing layer for the oysters. I think they need it. Will open them up in a few days.
Hello thank you for this really simple and sustainable recipe. Could I add horse manure to this and if so do I change the ratio of sawdust to straw or just add the horse poo to the 50/50 mix of straw and dust?
Hey really great vid! This one was really well edited! Question: Do you add grain in a still air box or laminar flow hood? I just did my first 4, 5lb bags in a still airbox and it was a real pain..
Ive been using a laminar flow hood. Before I just did everything in my bathroom.
Do you need seal the bag ?
Hey Ashley! Love your videos. Just got an inflatable monotub in yesterday. Hope it was yours! Could you do a video on how to make sawdust spawn bags? Very little info online, especially videos. I mostly see with pellets or sawdust and some wheat bran. And 2.5 hours at 15 psi. Is this what you would do? In what proportions? Thanks again. I’ve watched most of your videos… some of them multiple times!
I wonder if I can mix shred cardboard with sawdust instead since is more difficult for me to get some hay were I live ...
Great video! I’ve learned so much from your channel on top of other like minded individuals on youtube. I’ve been growing mushrooms since 2012 from buying supplies from avalonmagicplants since 2012 & midwest growkits since 2014 and recently I finally got pressure cooker & other materials to be my own retailer similar to my old suppliers while being able to grow way more mushrooms for way cheaper. Would you say this method would work if I put some wood chips into the mix?
Hi Ashley ! can we use this substrate for growing King oyster mushrooms ? or do we need some supplements like rice bran, cotton seddsetc. ?
And if the mycelium has covered around 70% of the bulk substrate than inoculate with a spore syringe? Or could I make the bulk substrate and inoculate afterwards?
Do i have to worry about chloronated tap water when i go to pasteurize?
Couple of questions. First the compliment! Thank you for taking the time to make these videos. Easy to follow and understand. I hit that Subscribe button! 1) The photos at the end look like you are using this substrate in a monotub. Is that correct? 2) Have you used a wood pellet (sawdust) watered down from wood pellets as a substrate in a monotub with success? In your title you call it sawdust, but I would call what you used wood chips. To me they are two different things. What do you think? Keep up the awesome vids. Love watching you move to see if the top view camera is getting the money shots!
Yes and yes. I have a video about how to grow oysters in a monotub where I use the substrate and it was very successful! Thank you!
The 'metal safety topper' (canning rack) that comes with the canner goes at the bottom of the pressure canner to keep the contents sufficiently raised above the bottom. Use at least as much water to cover it. The metal rack used at the bottom in this vid would probably be best used on top. It looks thinner, and heavier. Switch these two.
DO NOT 'RELEASE THE PRESSURE' manually!! Let it lower on its own as it cools down. Releasing it prematurely could cause big problems.
Also, use straw, not hay.
Finally! I came to the comments sections to find someone with some basic understanding of the matter. Your the first I found. Thank you for your brain!
I hear you, but releasing the pressure really only applies to canning. Releasing manually when canning does cause big problems for the contents in the jars, the duration under pressure, etc.
Can you post a photo or video with after the Inoculation process?
I like this 🤙🏾
Never mind just watched the end. Cool video boomer shroomer
@@allenallen3902 thanks
Seen this a lot with oysters , does it work for cubensis?
Nah, but woodlovers
As u mentioned, sawdust need to go through sterilisation. If only use straw can only pasteurise?
Yes! Ive seen a lot of people just pasteurize straw. I was going to try it too.
Did you use an impact sealer to seal you substrate bags, prior to PC?
No, I don’t seal them before I sterilize them.
I haven’t seen anyone mix straw and sawdust before for oysters, just use them separately. Have you noticed any benefits to combining them? I have some straw and sawdust that I was going to use, but was going to try them separately before I found your video. Curious as to whether you found any advantage in mixing. And thank you for such well explained videos. Especially your liquid culture video!!
I don't know if it makes any difference. I was hoping adding additional nutrients would make them colonized fast but I think its about the same.
Can I substitute Coco Coir for the sawdust since it's much easier for me to get Coco where I live.
Bro send me some 😭😭😭
Nice job, big fan of you videos. My favorite thing about your videos is that they’re so easy to understand and fallow along, you don’t cluttering up with music, just knowledge. Thank you. J
Hi Ashley, should I dry the straw some before sterilizing
No, I don't.
@@BoomerShroomer thank u and I think my substrate has been too dry producing smaller yields
what happens if we add like corn or other grains ? do we get more mashrooms?
Maybe... it will add additional nutrients. But you won't necessarily get more mushrooms.
Great instructional vid
Where did you get the bulk sub bags?
These are unicorn bags. Many sellers sell them. I got my from Meyers Mushrooms.
What could we use instead of hay? I can’t find coconut husk nor vermiculite either where I live
Well I always thought (and still do think) you wanted WHEAT STRAW specifically, and NOT hay at all. I think she may have just misspoken at the beginning of the video, because after that she keeps saying "straw", but they are DEFINITELY not the same thing, and you dont want to use hay.
Amazon has pretty much everything if you can't find it locally
I live in South America 😅
@@SachaLotus
Ok, that IS hilarious (I guess?) since everyone should just KNOW that. Do you not get MAIL down there or something? No such thing as online merchants? Just wondering, I mean TH-cam seems to work alright for you
tree moss can be used instead of coco coir (coconut husk), it maintains humidity without soaking up moisture. @@SachaLotus
These two bags in pressure cooker for 2 hours, would water get dry out?
Cooking water out of anything reduces the H2O of Earth forever. Do not be wasteful.
There is a fineline between using water to the point that it becomes endangered.
Can you use softwoods as well?
yes, and I also know people that use the wood pellets you get for BBQing.
do you seal the bags after they’re done sterilizing
I don't sell the bags. Sorry.
@@BoomerShroomer Do you vacuum seal you bags?
@@Gaunc3R Not until after I inoculate them.
Thank you for detail vedio. Can I use this for dung loving strains?
I’m not sure about that. I use a different substrate for my cubes.
How come that plastic bag didn't get burned/deformed when expposedto heat with pressure inside the pressure cooker?
Because it’s made out of polipropolyne , it has to say the number “5” on the label, other type of plastic will melt
Yay!!!
Any thoughts on wheat bran, coffee grinds as well?
I have heard of people using them.
Why wouldn't we add the gypsum *after* draining the water off?
U added before so the substrate can pasteurize
When shall we put the spawn please reply
After its cool. I would say at least 24 hours.
Hello is this a good substrate for lions mane?
No
What is the best substrate for lions mane in your opinion?
Hello What if You dont have a pressure cooker and where do we get The plastic bags you have?
You really need a pressure cooker.
You could put on the substate in glass jars to sterilize it with boil method
@@chrisc5047 you could..
Straw and hay are not the same thing.
👀🔥🔥🔥🔥🔥
Thank you!
Your great keep up the amazing work 🍄🌌
Ever try it without sterilizing?
No, I haven’t but I’ve seen other just pasteurize it.
@@BoomerShroomer I dont grow them yet but I was just wondering. Might start though. Thanks. Like them big portobello s
❤
O now u made me feel special. Lol. 2 hearts. Wow. I'm a lucky guy.
@@dustinperez5341 well you gave me a heart. ☺️
My my you are cute as a baby bunny Ashley 😍. So pretty
straw and hay are different
How are they different? Thanks
@@BoomerShroomer I believe hay is dried grass, straw is the stalk from cerial crops.
@@drd7209 interesting so i'm using hay?
@@BoomerShroomer From the video it looks like you are using straw. Hay is normally softer and finer, and wont give you splinters! But i am not sure if hay can be used for mushroom cultivation.
@@BoomerShroomer no Ashley you are using straw. Hay isn't supposed to be used for mushroom growing. Also there is a difference in appearance between the two and from your video that is definitely STRAW .
"give one tablespoon of gypsum" *Puts three full tablespoons into one container and another one in the blue container*
It doesn’t have to be exact.
Among other things…….I’m really thought this video was satire! I’m concerned that it may not be.
Will that platic melt on pressuring
