Lions mane help
    #26609761 - 04/18/20 07:34 AM (3 years, 9 months ago)

Hello all,

I'm growing Hericium erinaceus for the first time and everything was going well until fruiting, I think it looks weird. It has a pinkish /brown hue and looks stringy instead of ball-like. The bag that is open on the top was an experiment and I thought it was just growing funky because its growing up but the slit one is starting to grow like that as well. They are both growing quickly despite the weird shape. Any input?

I'm growing on supplemented oak sawdust. The chamber I set up maintains humidity above 90% for most of the day and I run a high volume blower fan on a timer for 5 minutes 5 times a day (over a 24 hour period). Maybe I'm not getting enough air exchange and its stringy like that because there isn't enough oxygen?

Thanks for any help!

^^^ Yep :thumbup:

The pinkish color they can get is normal, although I've heard many opinions on what causes it.

yeh its too much humidity and not enough air...I actually have a bag of lions mane growing now in a tub with perlite for humidity and while the problem isnt as bad as yours it still is real stringy. add more air

Okay, I'm going to set the fan to run for a half hour every two hours then, see if that helps. I just thought I didn't need that much FAE due to the volume of the tent, I only have three grow bags in there right now.

Now I'm wondering about the mechanics of humidity and oxygen availability. Why do you need more fresh air with more humidity? Does an increase in humidity decrease the availability of oxygen? After I read a quick google result it said humidity doesn't displace oxygen so, just not enough FAE even if there wasnt any humidity? Shouldn't the humidifier be adding fresh air to the tent as well?

I believe you are correct in the bold part.  The not enough air situation is not related to the humidity in any way that I know of. 

The main relation I see between fae/humidity is the fact that the more air you get flowing into there, the more humidity you're going to need to add.

Makes sense. I'm probably going to try your double extract on these guys if they dont shape up haha

That's what I was gonna say, if they don't look great for eating definitely don't let em go to waste, LM is excellent medicinally! :thumbup:

I prefer tincture but if you don't feel like it you can also just powder the dried fruit bodies.

I think it's better to run your exhaust cycle for shorter periods more often. As opposed to longer exhaust and long periods without.

If your fan is able to exhaust the full volume of your fruiting chamber in only 1 minute for example, it's pointless to run it for much longer as you've already completely exchanged the stale CO2 laden air with fresh air. It's a matter of establishing a balance with how much CO2 is produced in a given period vs the humidity lost and the new CO2 produced in the down time.

Ideally you would have the exhaust fan running constantly and only running the humidifier when your RH drops below a set point for your species.

But without a RH controller or CO2 meter, it would probably be better to exchange it every 10 minutes or so for the time it takes for your exhaust fan to completely exchange the full volume of air at least once. This is also largely dependant on how much substrate you have fruiting and the size of your chamber.

Yes this, I realized this after running a day on half hour every two hour cycles, it's a powerful fan and it's making it too dry now. The problem is I only have a digital timer with six on-off cycles and a mechanical one with only half hour increments. I just found out about cycle timers and ordered one of those so I can do something more like running it 2 minutes on half hour off, 2 minutes on half hour off, continuously. And I do have a RH probe controlled outlet I use for a humidifier for my magic mushroom chamber but those are much smaller and I have everything dialed down.

You can modify those analog timers to turn them into cycle timers. I've done this and it's pretty reliable. It's just a matter of reorganization the gear ratios. The one I did was able to turn each timer tab to 50s. Here is a tutorial on how to do it.

https://hackaday.com/2011/09/09/repeat-timer-hacked-for-35-minute-hydroponic-cycles/

The one thing about this is though that to open them they usually have tamper proof screws. So if you have a tamper proof screwdriver set it'll make opening them easier, if not you'll have to carefully drill out the screws.

Oh woah this is really cool. I dont know if I'm going to try this because I already ordered one and I can use the mechanical one for other projects but good to know 👍

That's frickin' sweet.  I have no need to but I might try just for fun :lol:

Also, your lions mane galleries are awesome. I hope I get to growing something that pretty here shortly. From your experience would you say lions mane needs more FAE than other mushrooms? To me it seems like it needs more FAE than psilocybin mushrooms but I'm also using totally different grow chambers and substrate volumes so it's hard to compare. I've never had FAE problems with magic mushrooms though, even when I first started

Thanks for the compliment, but I am very much an amateur and very hobby based. I've only really grown lions mane in that fruiting chamber and still have a lot of problems. I've currently got another round going of 38 1 liter jars. But my culture is fairly old and colonization is slow with my method and culture. About 30 days to colonize the jars. But in general all the gourmet mushroom require way more FAE When compared to psilocybe, to the point where constant fresh air while fruiting is best if you can maintain the humidity. The only exception to this that I am aware of would be with reishi antlers and king oysters.
You can look here for a general idea of the co2 requirements during fruiting of various gourmet mushrooms.
https://www.shroomery.org/11327/Gourmet-Mushrooms

Remember that generally a normal properly ventilated room for human living is around 500ppm co2. So if the mushrooms prefer close to that it suggest a lot of FAE.

I thought so to lol. I did it years ago and it's still been holding up. I thought it would fail on he first grow. Some of those digital cycle timers can be pretty expensive, I bought one I think for about $50 dollars here from a hydro store, but those day timers are only like $15-$20. The nice thing about them is because they are mechanical they're less likely to wear and break failing to switch because they don't have the cheap switching relays the digital ones have, which tend to fail after a certain amount of cycles.
