that's high CO2 - isn't it?
    #26446350 - 01/22/20 12:58 PM (4 years, 7 days ago)

Hi Guys,

sorry for double posting - I initally posted in the wrong board 

I browsed a bit through your forum to identify a problem I have with my grow bags.

So I purchased 5 fully colonized grow bags (yellow oyster, pink oyster, king oyster, pearl oyster and lions mane).
My set up is a 60x 60 cm x 160 cm grow tent (23 x 23 x 60 inch) - like that and I put in an ultrasonic humidifier and two hygrometer that show between 80 and 90 % RH. Two days ago i also put in some LED lightning. temperatures are between 18° and 20 °C (64 and 68 °F). But I apparently underestimated the importance of FAE - I opened the tent three times a day for like 10/20 minutes until I installed a fan just yesterday.

Today the yellow, pink and pearl oyster look like that:



the are leggy, with a huge base and small caps - thats probably due to the build up of CO2 - or could there be another reason?
Does the fan (it is a 10cm /2,5 inch axial flow fan with 14 W and 105 m³/h (3708,04 foot³/hour) need to be on 24/7 or could I at least turn if of for the night?


for my Lions mane I made the recommended cuts, but so far I only see one small primordial pushing against the foil at a non-cut position and one kind of pushing but now freed primordial in proximity to a cut. Are they just slower or is this also a result of the high CO2? when I see fruiting bodies develop under foil, should I cut the open?



For the king oysters I have some really small pins - so I didn't remove the sides of the bag yet, just the top. do you think it's time to remove the sides?

Yes you are correct those are indeed very air starved.

The kings look fine though, I wouldn't strip the bag just let them fruit on the top, the rest of pins should hopefully abort.

Keep that fan on 24/7. Is it set to exhaust or input?

Just noticed how you cut that hole by the Lion's mane pins - that looks good like you have it now it should fruit through there just fine, keep your humidity as high as you can.

Sorry but you're not going to get enough air for oysters with a fan inside a greenhouse, I don't care what the numbers on the fan say and neither do the oysters unfortunately.  You can completely unzip the front of the thing and put the oysters RIGHT next to it, but they're still gonna have trouble.  We see this all the time...

at the moment the fan is set to exhaust - as I figure that might cause less of an air stream(which apparently oysters also don't like?) - but i'm free to change that!

After installing the blue LED and having the fan on 24/7 I had almost all the fruits abort after loosing colour :tongue:

So, I read a bith through stuffand apparently they bleached as the light was to strong and the sudden change in conditions might have caused the abortions. In addition the fan is pretty strong, two times as strong the common computer fans, and it was really affective at loweing the humidty. I would have around 80 - 90 RH (as my humidifier is set to keep a level of 80 %) - as soon as the fan was on, not even after a minute the RH was down to around 60%.

So I changed my set up a bit. I actually have an 39 x 78 x 78 inch tall greenhouse which is transparent - so I can omit the blue LEDs , I figures as the volume is bigger, I'll probably have less problems with build up CO2, so, for now:
I keep the humidifier at 80 %, leave one of the doors of the green house open, when I'm home I'm additional running the fan for 5 min/hour   
asap I'll get a timer to do that and will install the humidfier to rather run every hour for 5 min - so that it's doesn't immediatly start when the fan is on.... (because that might be a vicious cycle and I'll soon have a RH in my whole room of 80 %).

in addition I snapped of all of the aborted pins and for the pink oyster I already have a new pin set, as well as for the pearl oyster - the yellow oyster had one small primorida unter the foil which I cut open. The lions mane increased in size since yesterday as well as the king oysters - but one of them has a white spot on the cap - i'll have to put some research in that.

so far, any advice or suggestions?

so, thats the  progress from yesterday to today... it's goint in the right direction, I would say? regarding the pink oysters - is that primordia looking good?

The aborts had nothing to do with the fan on 24/7, per se. What I mean by that is: Oysters have an absolute need of fresh air. Think outside air. So by you giving them what they need with the fan on 24/7 you would not cause them to abort. If you dried them out in the process though that could cause aborts. But not by giving them constant fresh air which they absolutely need. Also, it is usually strongly recommended to have a fan inside your fruiting chamber to move the air around so there are no CO2 air pocket buildups. Just don't aim the fan directly on the mushrooms. So, moving air doesn't cause aborts unless you are drying them out in the process.

The blue light could have caused issues. They need a full spectrum lighting 6500 K. And Bright lights for coloring. People have reported issues with using only colored lighting for mushrooms. Mushrooms are different than growing plants. A lack of a Bright 6500K lighting would cause a loss of coloring so they look white instead of blue. Even ambient shade from the sun with not really Bright but 6500K lighting would not be strong enough for them to keep their blue coloring.

You will most likely run into yuge CO2 problems with only running the fan 5 minutes per hour. Even if you open the door.

Your best bet is to run the fan on exhaust 24/7 and pipe that outside your house, keep your fruiting chamber door closed, unless you need it open a crack to let in fresh air to replace the air that the exhaust is pulling out. And then set your humidifier to keep the constant RH you want. The walls of your fruiting chamber should try to pull inwards. That will eliminate your humidity problem in the room your fruiting chamber is in. As well as you DO NOT want to pipe Oyster spores into your house. Do a search about spore lung and Oysters on shroomery. Because, by you changing it to what you are saying you are changing it to - is a road to a lot of frustration, to put it mildly.

Thanks for the thorough advise.

I have two 6500k lamps so I'll install those.

For the fan the issues is, that the fruiting greenhouse is currently  in my bed/living room so can't have it run 24/7 - otherwise I would not be able to sleep. And I really see a problem with the humidifier - as soon as the fan is on, the  whole RH goes down and the humidifier starts. With the fan on 24/7 the humidifier would also run 24/7...
And I also need to find a solution to duckting the fan exhaust to the outside...

Or I just might sit it out at the moment, as I'll move soon and will have a separate room for the fruiting green house.

I'll read into the spore thing, I didn't thought it would be that big of a problem  with only 5 fruiting blocks...

NP. Well, you would be surprised then that fan noise often will help people sleep. Unless it has some obnoxious bang and clang to it such as bumping against something. But it is like white noise and provides a nice constant background for sleep.

Yes, with the fan on it will not only suck the air out but also the humidity. It is a constant push pull compensate balance that you must find. Inkbird sells a humidity controller that might help you. You just set the RH you want and let it turn on and off the humidifier as it needs to.

You could get a small piece of rigid foam insulation for your window and just cut a hole in the foam and with some cheap ducting have the fan pipe everything out the window. Like a window AC without the window AC. You are growing food so no stealth needed.

I have no idea what amount of blocks growing or not growing would be the low level of not worrying about spore lung, but I would definitely think 5 blocks would be a concern. And everyone's allergy tolerance level is different. So you don't know until you know. And at that point you probably don't want to know. You could also grow a sporeless variety. You will find out more once you read some on it, besides me saying you need to read about it.

Sooo... I played a bit with the 'layout' and installed the fan and the humidifier on different ends of the greenhouse and somehow, despite the fan being really close to the shelf with the fruiting bags and the humidifier being around 1 m way , the humidity around the mushrooms is around 80 - 90 % while the fan is running. the stuff for getting the air out the window is ordered and should arrive next week and for the lamp I need to buy a cable on monday - but so far, I'm getting somewhere.

and the mushrooms keep growing, I'm actually going to harvest some of the biggest king oysters today. not sure about the pearl oysters.... and... they have some additional pinning kind of on top of the almost mature part - they will probably come of with the mature ones or abort - or what's your take? Here is a picture:
tiny pins above my almost mature pearl oysters

and here is the current state - still not sure about the pink oysters... is this pinset okay? and the yellow ones went really fast from primordia to tiny mushrooms - but do the look okay this time?
lions mane
yellow oyster
pink oyster
pearl oyster (same as above)
king oyster

might the growth of the yellow and pink oyster be a result of my temperature? I have between 18° and 20 °C (64 and 68 °F) - more on the lower side - which is more on the lower side for those to species. As i have read the pearl oysters and king oysters (and een lions mane?) are dealing better with the lower tempature.

is there like a chart of how the look for different mushrooms change depending on temperature and/or humidty and/or light ?

Yea and some deal better with higher CO2 as well. That is looking better on some. The Pearl? looks like maybe 3rd or 4rth flush?(top pic). 2nd pic looks wonky, but might be too early to tell. Yellows look leggy but they might just be growing out to give themselves room to grow the caps. You will know soon enough which. Yes, I agree your pinks look definitely wonky, but maybe they will grow out right in the end. A professional grower I follow sells an oyster to chefs that starts out wonky looking but when it grows out it looks great with big caps, so let it grow and see what happens. The one below the pink is looking OK. I have never grown Kings, yet. But those growths in the center look weird. Someone who has grown them before could probably give a better comment on that.

As for your question on the temps for the pinks and yellow. The yellow looks like either it needs more FAE or like I said above they were just growing long to allow all of them room to grow the caps out, but a little on the leggy side. You will know which soon enough. So I doubt its temps. As for the Pinks, I am not sure. Someone else may know that. Looks like cotton candy. :eek:

But once you set your exhaust up right and get the proper FAE and all that flowing and keeping your RH set, you will be growing many a happy Oysters. And avoiding spore lung. About to spawn some bags myself today.

I'm gonna agree it's not temps affecting how any of those look really, mostly airflow and humidity variations as you already know.

Definitely getting some improvement there.  The kings look great, don't worry about funny things on the heads they don't affect flavor or texture or anything.  Can't tell you what causes them but I've seen similar time and time again.  This was some beech I grew...
 
the first one looks like a mushroom cloud, on a mushroom :lol:

Your pinks I think just got too dry in primordia stage and it kinds stunted em wierdly, it doesn't look like they're gonna do much else.  Pinks IME never grow that big anyway.

I just edited the post and included a bit of description for the pictures.

For the pearl oysters I was wondering, if those tiny pins will abort once I harvest the more mature ones?
And it's kind of the 1st/2nd flush - right in the beginning of this thread, those reeeeeally leggy pearls, those were the first flush. Right after adjusting for FAE this pearl pinned on the same grow bag.
When would you say a flush is over? I mean, I thought there was going to be like a 2 weeks gap in between? I was kind of surprised that they all just kept getting new pins.

The lions mane is the same primordia that was already there before I had impoved my FAE and it's not doing a lot, it was actually covered under the foil and a bit pressed, I cut it open like 2/3 days ago, maybe that is why it is looking weird.

yes, those yellow oysters look leggy, I hope I'll be able to fix that, they put so much effort in :laugh:

For the pinks, you see this little patch of primordia on the right side - they look less weird, don't they? But yes, here again, this primordia started forming right after I snapped of the aborted primordia from the beginning of this thread and improved FAE... they are just really vicious growers!

For the peal oysters, I'll harvest them tomorrow - because I'll harvest the first king oysters today and will enjoy them with my best friend and some sparkling wine to celebrate my first semi own  grown mushrooms :laugh:
Regarding the kings I also did some research and found even funnier looking than mine, so, no mercy, I'm gonna slice and fry them up with a nice side of rice and salad :blush:

I'm really looking for my first really complete own batch,... but that might be still down the road for 2/3 weeks at least

For the pearl. Yea just harvest those small aborts with the big mushrooms. A flush would be something grows. You harvest. Something grows again would be 2nd flush. harvest. Grows again 3rd flush. etc.

And yea you can get a short time window between flushes. My blues do that. maybe a week give or take a day.

Ahh LM.. that makes more sense. Looks like lack of FAE which is why they look as they do. LM like Oysters require a boat load of fresh air to look right. I am still working on learning LM, but from what I have seen so far from what I am growing, at least the strains I am using, require more FAE than the blues to look right.

And yea the little pink cluster looks better than the big one.. but get enough FAE asap and see what happens. Pinks can be slightly more CO2 tolerant but that can also be a crap shoot on whether that will matter or not as well.
