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. https://www.amazon.com/gp/product/B0149S6VEW/ref=oh_aui_search_detailpage?ie=UTF8&psc=1

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.

do you have a basement? 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!

These guys do all their fruiting outside check out there videos. You will have to search through them and find what you need.

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)
