Indoor Oyster Mushroom Cultivation
    #25659883 - 12/05/18 05:25 PM (5 years, 1 month ago)

Hi, everybody I'm new here. Been lurking on the forums for a while but never made an account until now. I've been reading a lot about oyster mushrooms lately and plan on starting a batch myself. A lot of the local restaurants around here would like to have them fresh all year. My question is would it be safe to grow them indoors as long as I have a ventilation system and a sealed chamber for them to grow in or is that still a no go? I have seen the posts where RR talks about his allergy and I'm fully aware of the consequences, but I've never heard of anyone talking about how they grew them indoors. For example: Were they using proper ventilation? How many oysters were they growing? Did they use a respirator? Was the container they were growing the bulk of them in airtight besides the intake and exhaust?


With all of that being said I have also read of people growing them in their basements and watched videos of people growing them in a grow tent in a spare bedroom with no problems. All of them had a similar setup to what I'm doing. I built a box out of poly-carbonate plastic and wood. The corners are doubled up and have a 4th/5th layer of plastic over them to insure its airtight. The front door Velcros on or I could install a zipper of some sort. I have a proper exhaust fan that goes outside. I have a humidifier to keep the RH up and I'm getting a fan to stir around the fresh air. I would like to start providing fresh mushrooms to my family and friends due to the benefits of oyster/whatever medicinal mushrooms I'm capable of growing, but I also worry about the health of my family and newborn that is on the way. I would really love to start a new hobby and possibly make some extra cash from this. Hopefully someone can help shed light on the topic that is currently doing this or has done this! Thanks in advance and I'm excited to be a part of this community.

This thread was moved from Mushroom Cultivation.

Reason:
appropriate forum


for oysters indoors you'll probably want to use some sort of tent/greenhouse just to try to limit the amount of spores that will enter your home when they fruit.  Though they do good on their own in open air indoors if you can mist them enough 2-4 times day or tent them while you're gone so you don't need to babysit them as much. oysters are easy but prolifically make spores especially if you miss harvesting them at optimal time.

also twice a year you should have optimal growing conditions during what your spring and fall are. when it's in between 20 and 70 degrees F outside and during the most rainy/humid times you should be able to let them grow outside basically maintenance free.

Yeah I get they have a HUGE spore load, that's why I decided to come here to ask this question. I have built an airtight indoor greenhouse out of plastic. So hopefully that will work, I will also be trying to harvest them a little early to help reduce the spore load as well. I haven't really grown mushrooms before this but I have been doing a lot of reading and research. I went ahead and bought Stamets book to give me a nudge in the right direction.

I mean... I do both. Honestly there is a lot of useful information in there instead of having to filter through a lot of useless posts on here. Wouldn't really consider it a coffee coaster considering the guy is an expert and has been doing this for a lot longer than most of the people on the forums lol. But to each their own.

You need to see if you can find hardwood fuel pellets where you live and if you live where the weather changes from cold to hot you have to stock up on them while it is cold. You won't be able to get them in the summer.

You also need to see if you can find soybean hulls. I get mine from southern states. Mix the soybean hulls and hardwood fuel pellets 50/50. That is the best sub for oysters.



I mix in four 5 gallon buckets that is why it says 10/4. I get 10 bags from 4 buckets each bucket gets the stated amount in lbs and liter of water.

These videos will help you also.

I'm actually in the same position and starting out. I've already gone through all of the meyers mushrooms videos but he doesn't seem to have a lot of content on the early days of his cultivation.

I just got a marthas GH setup ordered as well as a humidifier/controller. Does anyone here fruit in their home? I'm a little concerned like OP about air exchange and avoiding water dmg in the home.

If fruiting in the home you want a passive air intake. This will create negative pressure in the fruiting chamber. Something like this...



The thing above the humidity sensor is a circulation fan.

Flaper
https://www.amazon.com/gp/product/B00009W3HB/ref=oh_aui_search_detailpage?ie=UTF8&psc=1

What this does is when the exhaust fan turns on air is pulled in through the flapper. No air is being pushed in. Pushing air in would create positive air pressure which would push out spores into your house. You will need a small fan to push in the humidity but that won't be much air. So it won't make enough positive pressure to push the spores into your house. The reason the humidity sensor is placed on the intake of the circulation fan is that the circulation fan is blowing out and down the sides of the tent mixing with the humid air. Once it is mixed it goes through the intake so it gives a better and more consistent humidity reading. Plus you don't want air blowing directly on the fruiting blocks.

Thats brilliant. Noting this for when I'm rdy to build. I will likely vent out through a window. Will likely have to find one of those partitions that are used for ac window units and modify it.

I was planning on running the humidifier unit INSIDE the tent. Is that a bad move? Seemed easier than how some people run it via pvc from outside. I know the advantage of fresh air is pretty huge just not sure how i would do it.

No unfortunately i do not lol. No shed either. BUT I have ~2k sq ft house and live alone so i'm trying to get creative. If i did eventually go commercial I would likely get a shipping container for fruiting since i live near a port.

The fresh air is what is coming in through the flapper. It comes in from your house or garage or whatever room the tent is in. So when your exhaust fan comes on it will exhaust the old air and pull fresh air in through the flapper. You should have your exhaust fan on a cycle timer and do a complete air exchange 4 to 6 times an hour.

Cycle timer
https://www.amazon.com/gp/product/B06Y3192PG/ref=oh_aui_search_detailpage?ie=UTF8&psc=1

The reason people put the humidifier on the outside is so they have more room for fruiting. You can put the humidifier inside the tent but I would use an ip68 fan IP68 is mostly water resistant.

This is the IP68 fan I used and seems of good quality.

Sorry should have clarified. From reading other posts i've seen people weigh the options of placing the humidifier inside the tent vs outside. Outside provides the benefits of using fresh air vs it being inside the tent and just using whats in there.

I still suggest taking advantage of nature and fruiting outside when possible.
shiitake seems to not be too bad with spores at all you could supplement your mushroom desires with those indoors.

I edited my last post you might want to read it again. Trust me they are not getting near enough fresh air by running it that way. You are going to need a passive system as I described above. Then if you don't mind loosing the space inside the tent you can put your humidifier inside with the proper fan.

Unfortunately no since I live in FL. We call those indoor pools down here lol

I do have the advantage of having a bit of land. Almost an acre and since its FL humidity is something i could definitely use to my advantage. I live on the coast in zone 9a

are oysters that easy going? Part of the year I guess i could inoculate indoors and then fruit them outside undercover? I've done SOME reading as im new but haven't seen much on fruiting bags outside.

This is an option. But shiitake take way longer to see fruit. So you have to stay way ahead of the game and have way more room for colonization because they take so long.

Perfect. Ok i will do that. Humidifier outside as well as the passive airflow via exhausting.

much appreciated!

a Lanai? haha
pretty warm down there grow pinks outside all year and sell them for a fortune to the rich people

if you're on the gulf coast mushrooms absolutely thrive there. (especially cubes)

there's plenty range in oyster species and strains in temperature. the "typical" oyster will tolerate freezing no problems. you are in a situation where you probably can grow almost  everything we envy having a natural habitat outdoors for no problem most of the year and grow everything we envy the same for at some point during the year.

Yeah I have an indoor room setup similar to that with the exhaust fan pulling air out and fresh air coming through the passive intake. I have most of it setup now. I will post pictures when I get the chance. I'm super stoked to start this endeavor. I'm mainly worried about the spore load but my exhaust is pulling the spores out of the house and the enclosure is so airtight that the sides suck in tight when I have my fan on full blast. I have the proper cfms and its set to cycle 4 times an hour. The humidifier is keeping it at around 80% RH on full blast. I think the setup is working sufficiently atm. The next step is to test it with the actual mushrooms.


P.S. I want to document this experience because its hard to find a lot of information about people growing them indoors safely, even though I see tons of videos of people doing this exact thing with no info on the logistics or safety protocols. I DO NOT want my family getting sick from spores. I also have a background in chemistry so I know a little bit about venting things you don't want away from the area for safety.

The only problem I see with the martha is that to my knowledge they aren't airtight (Unless you found one that is all the way around and not just on the tops and sides)… I'm also very anal about things being the way I want them to be so I may have gone overkill :shrug:  Anyway, the martha not being airtight and not having an exhaust to pull it out of the house might lead to spore leakage outside of the enclosure which is what I'm trying to avoid for my lungs. Just my .2 c! Good luck though!

Yep, that's similar to my setup. Mine is a 6x4x4 box I built that's airtight with a passive intake and an active exhaust venting everything outside. Thanks for the affirmation!:thumbup:

My room is 10 x 4 x 7 (L X W X H) I found that the pond foggers do not last very long and at $200 each for a 9 disk fogger. I built this instead. If your room is smaller you can adjust the # of misters.

Having trouble find both of those ingredients for the substrate... can you buy soybean hill pellets? And I'm assuming I can get hardwood pellets like oak from a hardware store.

Yes, you can buy in pellets and powder. I would think the powder is easier for hand mixing. Call feed stores. I get my soy hulls at southern states. Fuel pellets you can get at any hardware store just about (tractor supply, southern states). If you live in a state where the climate changes you must stock up in the cold weather or you will not be able to find them in the summer.

Thanks for the tips! I got about 80 lbs of hardwood fuel pellets for like $8 at Menards. I just need to find soybean hulls, if I can't I'm sure supplemented hardwood would do just as well as straw (probably better). I kind of live in a city but there are farms surrounding the area so I might be able to find something.

The main thing I like about the fuel pellets is that there will be zero waste water since I can calculate exactly how much lime water to mix in to it to fluff it up. Glad someone talked me into it because I heard straw can get messy lol.

Idk if you supplement yours since you use soybean hulls, but I was thinking about using wheat bran in the mix at 10% or less if I can't find the hulls for some reason (That's what I've been reading on here)? I already have gypsum and the correct lime for the pasteurization process. I'm not sure if I have the right gypsum though, I got pelletized garden gypsum from the green house, its dihydrate... like 16% sulfur and 20% ca? Haven't found many posts pertaining to the correct type to use besides RR talking about it a little bit.

Ordering my spawn today or tomorrow!

Soy hulls are supplement. Just about any grain or by-product of the grain would be considered supplement. Different types of hay would be considered supplement,  most commonly; alfalfa.

Grain supplements require sterilization. Some get by pasteurizing alfalfa pellets and hardwood fuel pellets.

So I'll need to either boil or PC supplements versus the lime pasteurization for the fuel pellets? Is there a reason why you can use lime for the supplements?

Also do you guys have any recommendation on who to buy oyster spawn from when first starting out? I would eventually like to get into cloning/cultures/agar work... but for now I'm just dipping my feet.

Here is the recipe I used b4 I started using soy hulls...



If you can find soy hulls that is the way to go. with soy you will get bigger flushes and fruits.

I use a flow meter that is why the water is in liters. The 10/4 is because I was mixing in 4 5 gallon buckets with a paint mixer. Each bucket got the listed amounts to make ten 6 1/4 LB bags.

As stated you will need to sterilize your sub. You may want to think about building a 55-gallon drum steamer. PM me if you need help building a steamer I am currently helping someone build one so I have all the drawings for the electrical work ready to give to you.

I kind of planned to do a recipe like that with wheat bran/soybean hulls. I eventually would like to rig up a burner so I can just sterilize it all with a hot water heater... Would probably be a lot less science involved lol. I'm waiting until the baby gets here and we move out of this house so I can double up on stuff and have a semi permanent place to keep all my new gadgets. This is all my learning phase until next year when we move and I can decide if I want or need to go bigger :thumbup:

If you use anything together with the soy hulls you will do more harm than good. Soy hulls and fuel pellets are enough! You don't want to over supplement. I get at least 100% BE with soy hulls

Not sure what you mean by a hot water heater and a burner but a 55-gallon drum is like $10 on craigslist a timer is like $20 and a heat controller is like $20 then you need a float valve which is about $25 and an electric element is $25. So for under $150 you can have something that will do the job well. Just set in and come back the next day and it is done. Check below for how to build a steamer.

Just wanted to note that I grow indoors using hydroponic grow tents from Ipower. 

They are not air tight.
If you don't suck at harvesting spores rarely accumulate. 

Point of this post - I use forced air intake and forced air outtake.  It just a matter of making your exhaust fan stronger than your intake fan. 

This way I still have negative pressure with a huge abundance of fresh air coming in.  I don't have ways to create a passive air intake system in my current environment.  Who the hell has a garage without a window anyways...oh yea... me. 

I can tell I have negative pressure because they tents will literally suck around their framework like their caving in!  Mission accomplished.

There's lots of ways to skin a cat. 
With that said - the GGMM book is just one cat. 

I personally have found a balance between existing knowledge in books, browsing the forums, and the occasional youtube video - but those essentially just show me exactly what I don't want to do. 

End of the day results ?  The books get your mind rolling, and then your realize 20 years had gone by and there's a 100 better ways to do things. But regardless knowledge is power and it all helps us wrap our minds around mushroom cultivation.  There are many specific instances the book explained something so common sensed and yet so profound - where my mind says DUH while reading it, yet I know I could have easily struggled to come to the same conclusion. 

Should I angle my fan more, what happens if I change this, etc etc etc.  I think you get what I'm getting at.  Altogether with community knowledge and written in stone knowledge - it helps us get to that next level of critical thinking of the task at hand.

From the sound of what you are saying you are exhausting into your garage. That is a big no-no. You are going to do harm to your lungs breathing in spores.

If you Remove the intake fan and leave the hole that is a passive intake. I would suggest you find a way to get the exhaust out of the house!!

A passive intake just draws air into the tent from another room or in your case it sounds like from outside the tent (ie another room) without a fan. People use passive intakes when they have a problem keeping humidity up and they always exhaust the spores outside the house in either case passive or not. The way you have your set up sounds fine you have negative pressure. but negative pressure does not matter if you are not exhausting outside the house. I hope I just read your post wrong and you are exhausting outside.

Yeah I feel you... Knowledge is power! You have to reach out everywhere. I'm now just using the book for references to temperatures for the various cycles and fact checking other things with what I learn on here and youtube. Honestly Shroom has been a huge help, loads of people on here can really help get people doing it for the first time in the right way.

I would agree with shroom though, venting the grow into the garage is dangerous if you're in there a lot. Spore exposure is bad. Unless you have some sort of hepa filter for the exhaust that you change regularly and those reduce cfms significantly.

My tent that I built sucks in as well, so I know I'm doing something right. Mine is practically air tight because I'm so anal lol. Caulk and foam do wonders!

An update on my grow...

So I started my first batch of sawdust substrate with 3015 spawn. Those are moving along with no contams as far as I can tell. They've been in there for about a week and a half as of today. The temp sits at around 65-75 degrees depending on the time of day. Hope to have full colonization within a week or so considering its pretty cold around here and I tried a lime tek for the first go around it may take a bit longer than that. I have already been convinced to build a steamer so I will have that rolling for the next batch I make... More consistent results for a small farm grower from what I've read on here.


I have also started my first round of homemade grain spawn on rye. I believe I followed all the procedures right. I watched RRs videos on rye berry preparation. The grain was perfect when I put it in the jars with no extra standing moisture. I inoculated those in a SAB I made. I inoculated 4 jars total, 2 Pulmonarius and 2 Blue Brat from an LC I acquired from http://out-grow.com/ Its only been 72 hours and all 4 jars show no sign of contams with mycelium forming on the sides and top the grain. The pulmonarius is way ahead of the Blues but that was expected from research... The pulmonarius already has a couple dime sized masses growing in each of the 2 jars. This hobby is amazing!


I would highly reccomend http://out-grow.com/ if you're trying to find LC for almost any edible strain, and they are a sponsor of The Shroomery too!

Hi, everybody I'm new here. Been lurking on the forums for a while but never made an account until now. I've been reading a lot about oyster mushrooms lately and plan on starting a batch myself. A lot of the local restaurants around here would like to have them fresh all year. My question is would it be safe to grow them indoors as long as I have a ventilation system and a sealed chamber for them to grow in or is that still a no go? I have seen the posts where RR talks about his allergy and I'm fully aware of the consequences, but I've never heard of anyone talking about how they grew them indoors buy magic mushrooms canada. For example: Were they using proper ventilation? How many oysters were they growing? Did they use a respirator? Was the container they were growing the bulk of them in airtight besides the intake and exhaust?


With all of that being said I have also read of people growing them in their basements and watched videos of people growing them in a grow tent in a spare bedroom with no problems. All of them had a similar setup to what I'm doing. I built a box out of poly-carbonate plastic and wood. The corners are doubled up and have a 4th/5th layer of plastic over them to insure its airtight. The front door Velcros on or I could install a zipper of some sort. I have a proper exhaust fan that goes outside. I have a humidifier to keep the RH up and I'm getting a fan to stir around the fresh air. I would like to start providing fresh mushrooms to my family and friends due to the benefits of oyster/whatever medicinal mushrooms I'm capable of growing, but I also worry about the health of my family and newborn that is on the way. I would really love to start a new hobby and possibly make some extra cash from this. Hopefully someone can help shed light on the topic that is currently doing this or has done this! Thanks in advance and I'm excited to be a part of this community.



I just received my oyster mushroom spawn in the mail and went through the initial process this morning.

The kit I got was the "TP" kit ( Toilet paper).

I did it last year and it worked out so well, im doing it again this year.

Here's the basic process

- Saturate toilet paper with boiling water
- I used kitchen tongs to submerge
- I had 2 large pots going at once, cause the TP is so absorbent, It allowed me.
to have a constant pot of hot water as the other was coming up to temp.
- Its amazing how absorbent it is. I get about 4 rolls per pots before I have to.
refill with water again.
- Some of the outer paper will separate, so I fish it out.
- Let saturated TP come to room temp
- I used a drying rack
- Place TP in the mushroom bags ( They have a breathable filter)
- Its important not to introduce any other organism to the process, so I used
medical cloves when handling the bags and spawn.
- Fill the center hole of the TP with the Spawn
- Close the bag with a rubber band ( make sure above the filter
- The kit came with 3 varieties, so I labelled them
- Keep at room temp in a dark place for 2 weeks
***This is where I am today***

- In 2 week's the bags go into the fridge for 48 hours to ' shock' the spawn
Into producing
- The bags will then be removed, placed in indirect sun at room temp and over the course of a few weeks will produce clusters of oyster mushrooms.
- The will have to be misted daily with a mist bottle
- Each bag could potentially have a few batches

***I dont have to do all the bags at once ( 15 bags). What I have done in the past, is just do 2 bags at a time so I can spread out the production through the winter. The bags can last in the fridge for about 6 months***
