You guys have been super helpful. Thanks to your videos, I have 2 four foot polytubing logs (4 mil lining and 10" diameter) sitting in my grow tent waiting to grow a ton of oyster mushrooms.
You guys are amazing. Although I can't do many of the procedures for several reasons, I do share your videos on all the alternative media (i.e. not Facebook or related) I've joined. Congratulations for your educational activism and for helping us keep our Mother Earth healthier, also promoting such cruelty-free food!
Cool video, my favorite so far. I absolutely love low tech and being off grid is essential to being balanced. Quick question, have you used or know why caustic soda isn't being used?
Can we use the lime bath water on another batch of straw as soon as we pull out the first batch after 16-20 hours. My vegetable garden is no till in straw, figure I should get as many uses out of the straw as I can.
I found this video super helpful. I had just finished watching a whole stack of videos on making steam pasteurization units- it struck me in times of rising energy costs, -they seemed possibly costly- my one question is- if you have raised the ph so much, with the lime method, and achieved Field capacity in the substrate at the same time- how can the mushrooms /mycelium cope with such a high PH? I believe you, that they do- I'd just like reassurance before commencing this method, as it seems the best, so far, by far-to me!! thanks guys :-)
Could I pasteurize wood chips with the lime or ash? You mentioned sawdust, but not chips. I'm looking to make a really big amount of spawn for a really big Wine Cap bed. I also have tons of branches to run through my chipper, but they've been down for a few months.
if using coir would you, "Add the lime to the coconut" but don't drink it all up or you'll say "Doct-tah!" ----------------------------------------------------------- if you heat with wood,[or have a friend who will trade you] ash is a no-brainer and the mineral content for the shrooms is excellent. The lime or ash pH methods also do a preparatory hydrolysis that opens the cellulose for mycelial digestion. That and the minerals is why yields are better. hey fellas, I like your style
@@GroCycleTV When we were naming our farm my wife drew a picture of a farmer with a large semispherical abdominal protrusion and proposed that we name the place "Big-Belly Acres" But we were both quite slim so then used YBT Gardens. "You Betcha Toots" was my stock answer when ever she asked for help on something.
Lime is an alkali so any acid would work to neutralize it. I’ve seen people say that you can expose it to open air and it would react with the co2 in the air and turn into calcium carbonate, but that can take a long time. For acid, you could use vinegar. Add it, wait until it stops reacting and measure pH. Don’t use stronger acids, it’s risky. And don’t take my advice as gospel. Work safely in a ventilated space, take precautions and do your own (extra) research. I’m not a chemist ;-)
what about baking soda and ANAEROBIC PASTEURIZATION (only water)? after googling around i found that egg shell mean calcium that can go to ph7.4 to ph9.2 ?
Great job Grocycle! I will try lime pasteurization with straw and use bucket to start growing oyster mushrooms. May i just ask what can i supplement to straw if i soak it in lime water to give more nutrients. Most of growers here use 70:25:2:3 straw/sawdust/molasses/rice bran and steam pasteurization. But your method is the kost economical. Please advise.tyvm
Interesting, is the residual acidic/basic moisture in the substrate not a concern for the mycelium? No need to bring it back near neutral pH? I don't know how I was unaware that cold pasteurization was even an option. I'm nano-scale and not trying to turn a profit, but on reduced effort alone this seems a major upgrade. Time to experiment!
You are doing a great job passing on these techniques. I have a question: by pasteurizing through raising the ph with lime, after the treatment wouldn't it be appropriate to neutralize the ph to values of 7, considering that all fungi like a ph between 6-7? Residual moisture in the substrate would still contain high ph water and could affect the mycelium. Wouldn't a simple wash in ph neutral water before draining and adding the spawn be a good idea? Thank you for the great job of disseminating your technologies!!
2 simple questions. 1. Do you neutralize the pH lvl somehow or doesn't matter for the included mycelium? 2. What kind of mushrooms are idle for this kind of substrate?
I live in Southern California where we are conscious of wasting water. The lime approach to pasteurization appeals to me. If I added something to raise the pH after the pasteurization process, could I then use that water for growing vegetables in my garden? Do you have any suggestions? (You two are a gold mine of information-Thank you!)
Water is a very precious resource indeed. With Lime you would not to reduce the pH and then should be fine. you could also consider recycling the water in a shower like system.
I suggest to check first the ph of your soil, if the soil is acidic then you can neutralize or make it more alkaline with lime water. For example, if you are planting or already have berries this option is not for you since berries prefer acidic soils.
Thanks for the great info. How do you go about draining the straw bags? Do you have a valve at the bottom of the food container or you you hang the straw baskets? If hanging would this best be done in an indoor or outdoor environment?
Hi GroCycle Team. I find it very interesting about the method of PASTEURIZATION. I've seen this Method in a video from Nepal wherein I was amazed that they are not using STERILISATION method. And there I found in your video this fascinating works. My concern now is the RATIO. Will you be able to make a video or comment back to us the ratio of mixture of chemicals for us to have reference if we apply it. Thanks
Yes, and we've done it a lot! If you can mechanise some of the process, you can cut down on some of the man hours involved too.. just need larer scale equipment and space, but it's all scalable!
Would you be able to use one bucket full of high pH water to pasteurize multiple batches of straw, assuming there is enough solution to fully soak the straw or do you recommend only soaking straw in a freshly mixed solution of lime and water and dumping the solution after every batch?
Reusing the water- we've seen this done in the form of a 'closed loop' system where you circulate the water and use a shower to spray over the susbtrate
@@GroCycleTV that is interesting to hear, i think I might try to convert my homebrew mash tun into a lime pasteurization system. Thanks for the advice.
I mixed hardwood chips and 10% (of the dry weight from the wood chips, normally is 2kg of dry woodchips turn into 7kg of hydrated weight) of soy bran. I'm getting a little bit of contam ;/
There's an even cheaper and better solution! I discovered that by accident and then read about it and it was the best method I ever found! I once got too much water in my grow bag and the bottom didn't colonize because it was soaking wet. Instead it fermented. After 2 Weeks or so I cut open the bag and draimed the water out. After that the mushrooms did colonize that part of the bag in a spee I never before have seen! Ther was zero contamination in that part (even the upper dry part of it had mold) and was extremely quickly colonized by really strong mycelium! So basically let your substrate rot under water for 2 Weeks, drain and inoculate. It stinks while rotting but its the cheapest, easiest and even best way I saw until today!
I think the cellulose is breaking more thoroughly and the colony can digest it quickly. I will probably have to experiment with extended soak times and ash content to test this hypothesis. Many think your report is hooey, but lab accidents often lead to next level knowledge. thanks for paying attention.
Does anyone known if i can use timothy hay for growing rather than straw? I have Timothy hay for my rabbits and it would be very convenient if it would work as well
Hey guys great vid..I have a quick question though...Does using hydrated lime or the chlorine method make the substrate and hence the mushrooms non organic???
I started some golden oyster on straw June 13 they started to pin about a week ago but haven’t done much since . Although I am noticing some new pins. I thought they would flush sooner, wondering if they’re OK.?
Hello from India bro I was just wondering how long we need to keep lights on for our fruiting room per day ? So no need of darkness after moving to the fruiting room? Please reply. Many Thanks
Hi, thank you for sharing such valuable information. I want to ask if I can use a ph-up liquid (like those used in hydroponics) instead of lime. The base solution I normally use is formulated using potassium hydroxide and potassium carbonate.
I have a bag of hydralime from bq will that work... :) cant find the data sheets on it ,any help would be great if it will not work is there a link to a more suitable easy to get hold of supply, any help appreciated to the moonshroom n back lol
Can i re use my water after i used it once for another batch? I put lime in there till the ph is 12.5 and then the straw. I do this now a few times a week and it feels as a waste of the lime and environment to just throw it away after one use
Question: Does the highly alkaline solution of lime water have any impact on the container used for pasteurisation? Is there any chance for example that plastic (or metal from using a steel drum barrel) from the container would leach out into the substrate from using this method?
What type of mushrooms WOULD NOT benefit from these methods. Is this ONLY for wood lovers? Some types enjoy a slightly acidic environment. Would a hydrated lime bath be too base for the mycelium to overcome?
so, why can't you just keep the lime water and re-use it several times? Add more lime of the pH falls to low? i do realize it will get cruddy after a few days. but store it outside in a black plastic barrel, and that should keep it sterile, no?

You guys are doing a great job. Thank you for contributing so much information to the mushroom community.
What a wonderful video about cold water pasteurization! Thank you for sharing.
This is amazing 💪thank you for your video guys. Testing out the builders lime this weekend and will have to give feedback in a months time 🎉🍄
I love you GroCycle! So informative and so innovative!
Wow, you guys are great at making videos. Fantastic job. Thank you.
Hi guys, thank you for your videos all of them are very helpful, where can I find more information about the vinegar?
Just the video I've been looking for! Thank you!!
hey thank you for this video. How do you feel about keeping the water for next weeks substrate?
Thanks for this. What's the ratio with vinegar?
Please add / wear safety glasses around lime for eye security. Otherwise great info. Topz! I especially appreciate cold water methods.
Great video! Thank you for sharing the knowledge!
Quick question: Can the water be re-used?
Does lime pasteurisation works for saw dust?
Appreciate the video!

Great job, thanks again for your awesome work 👏
Complete eye opener! Thank you! Also maybe squeeze a lemon in to bring down pH before discharge.. :{)
Nice video if possible make a video for machines used in mushroom cultivation
Thanks alot ❤

Rising energy costs is a misnomer.
It's simply rising consumer energy charges.
The cost to produce is no higher than it was.
Look on craigslist at the firewood adds. the guys that sell firewood know customers who would trade you ashes for a few shrooms.
Could I pasteurize wood chips with the lime or ash? You mentioned sawdust, but not chips. I'm looking to make a really big amount of spawn for a really big Wine Cap bed. I also have tons of branches to run through my chipper, but they've been down for a few months.

What's perfect pH level of substrate while colonization and fruiting?
Great videos! You mention vinegar pasteurization, any plans to elaborate the findings? Have you tried it. I was going to give it a whirl as well.
As always very informative video's. Have you guys considered using ozonated water?
Great idea and no direct experience yet.

The mycelium will grow fine in high PH but contaminants will not
@@mashjprime2795i think it because oyster mushroom that can tolerate high or low ph.
did you try shiitake with cold past? or other mushroom?
@@mashjprime2795 That is interesting. I am trying with regular white buttons mushrooms.

Thank you for the great job of disseminating your technologies!!
Probably true, but wouldn’t you also lose a lot of nutrients as well
So the substrate is not rinsed to bring the ph back down before inoculation?
No rinsing after the bath? Just draining?
2 simple questions.
1. Do you neutralize the pH lvl somehow or doesn't matter for the included mycelium?
2. What kind of mushrooms are idle for this kind of substrate?
No need to neutralize, but you need to drain
Oyster and other culinary strains are mainly straw (woodlovers basically)
@@MattRoadhouse lol. I just drained it with no rinse, and it smells like cement. lol We shall see if it grows.

is it possible to lime pasteurize straw pellets?
Nice video
Cool. I am trying the wood ash method. talk about dirty, but we will see if that impacts the yield because I only drained it, didn't rinse.
How much bleach and vinegar per liter of water is needed for pasterization?
Very helpful video. Want to know, what would happen if we add too much lime?
Mycelium don't mind high ph. Around 13 or so will do the job.
Hi GroCycle Team. I find it very interesting about the method of PASTEURIZATION. I've seen this Method in a video from Nepal wherein I was amazed that they are not using STERILISATION method. And there I found in your video this fascinating works.

Can I re use the water for pasteurize another batch?
I can't find builders lime anywhere. Where do u get it?
I just paid $36 for 5 lbs. The only place I could find. Where did u get yours?
is this the same with button mushrooms?
Can we use lime method with sawdust ?
In cold water Pasteurization. What's the water temp? Is it like tap water in winters or icy water?
Can you use this method for coffee grounds
Can cold pasteurization be used for mass production?
Yes, and we've done it a lot! If you can mechanise some of the process, you can cut down on some of the man hours involved too.. just need larer scale equipment and space, but it's all scalable!
What percent chlorine solution would you suggest when using pool tablets to sterilize?
Do you need to reduce oil in your growing area as part of the maintenance / cleaning?
Sir, can i use caco3 for this? And how much?
Does this process also work for Non-wood (manure) mushrooms?
Manure needs sterilization

I have a question
Why when i use this method my substrate smell bad after 12 hours?
And it became hot from inside
Hello sir.... your video is very helpful for me....I have few questions....which one is best lime bath or other chemicals
wood ash

Can I also safely use sodium bisulfate to raise the PH level for pasteurization? Thank you
test it for yourself
Do this then mean that the wood type doesn't matter when you are steam sterilisering? All So what is it about the process that Changes the efficiency?
Does this work for coir as well?
yes.
You" add the lime to the coconut"
Is there a reason why PH up to PH 11-13 wouldn't work?
How about bicarbonate soda? It increases the ph level of water too.
Chemically you should use lime because of hydrogen

Got a question - When your draining the straw how to you prevent the straw from becoming contaminated again?
by inoculating it with spawn.
Can i re use my water after i used it once for another batch? I put lime in there till the ph is 12.5 and then the straw. I do this now a few times a week and it feels as a waste of the lime and environment to just throw it away after one use

Question: Does the highly alkaline solution of lime water have any impact on the container used for pasteurisation? Is there any chance for example that plastic (or metal from using a steel drum barrel) from the container would leach out into the substrate from using this method?
High pH can definitely react with metals but wont react with a plastic bucket.

Has anyone used this method for shiitake?
I think it will be cool to add the anaerobic pasteurization. It smells bad though
How about a combination of lime and bleach? (So maybe you could use lower dosage rates of each and get even more effective pasteurisation?)
It will give off a very deadly gas that will burn your lungs.
Ratio for bleach?
so, why can't you just keep the lime water and re-use it several times? Add more lime of the pH falls to low?
i do realize it will get cruddy after a few days. but store it outside in a black plastic barrel, and that should keep it sterile, no?
