Humidity to high to case
#5416093 - 03/18/06 02:35 PM (17 years, 10 months ago) |

I recently cased two pans of WBS with 50/50 with ground and crushed oyster shell. I let them recolonize for a day and a half and then dropped them down to room temp, started fanning them, and am giving them 12hrs of blue spectrum light each day. They are currently sitting in their own Rubbermaid containers that are designed for hanging files and have a clear lid. The boxes are approximately 1'8"x1'x1'(LxWxH). I don't have enough time to fan them all the time but am worried that too much humidity is building up. Their humidity is so high my hygrometer which stops giving a readout at 99% just shows --%. When ever I fan them the humidity drops to around 75 and then slowly rises back up to --% (about 10-15min). I know that my humidity should only be around 90% at this stage for Psilocybe cubensis.
My question is should I try drilling holes in the lids and filling them with polyfil to allow for more air exchange or should I hook up a filtered computer fan and have that blow air in for 5 minutes every our or so?
Any help would be greatly appreciated.

you should be ok, cubies can take high humidity like that, its just not the best humidity range for casings. if you drill some holes and fill w/ polyfill that should help ya out, and you woudlnt need to fan anymore. you would be making a single tub. you would want to make 4 holes, 8 total on each side about 1" and fill w/ polyfill.

A computer fan works great for FAE, but a coolmist humidifier is superb for automating FAE and keeping RH at optimal casing levels. I use a cheap coolmist on a 1hr.on/1hr.off cycle, running to 3 large monotubs, and it works like a charm. Lights set on a 12on/12off timer. I fill up the reservoir every couple of days, and harvest weekly. Give it a try.

I guess I should add that I did a bottom layer of drained perlite to a depth of about .5". I think this is part of the reason I'm getting excessive humidity.
While I appreciate the coolmist idea I'm not sure that would help in lowering my humidity to the desired 90% range. Perhaps next time I should leave out the perlite and go for the coolmist.
Also I'm still new to this board so I'm not familiar with all of the acronyms yet. Does FAE stand for frequent air exchange?
If this is the case does anyone have an opinion on what would be better to use the polyfil or the fans?
Thanks to all that have helped already and to those who will provide future advice.

well you have not lowered the temp untill the casing was colonized and then you lower the temp but you want 95% humidity during the pinning prosses and 90% during the croping here read this http://www.shroomery.org/forums/showflat.php/Cat/0/Number/3290155/an/0/page/0

OK yeah, I see what you mean. Right now the humidity at that level isn't to much of a problem. But one of them has already started to pin pretty heavily and I'm worried that once the cropping phase initiates that there will be to much humidity. Is it possible that since they are roughly 90% water anyway that once they start to fruit they will naturally lower the humidity to a more optimal level?

After looking at some other box ideas I guess I'll take willmafingerdo's advice and go with the polyfil idea as it is simpler. I have polyfil and tyvek. Does anyone have a suggestion as to which I should use for this application?

I always keep the humidity at 100% for my casings. Works great.

I fruit at 95%+ all the time. No worries. Just get more air exchange for fatter fruits.

Drill some holes in that container asap. Filtering isn't required or even helpful in the fruiting environment. Leave the polyfill out of the holes and you'll get more circulation. FAE=Free Air Exchange. RR

Interesting RR. Almost everyone this board says that you need to have Polyfill in Monotubs and PMP's to prevent contams from entering.
I may try removing the polyfill as you suggest because i cannot get my RH down below 94% in my PMP and I have probably 12 holes in the lid.
Although I have had no problems fruiting with the RH being that high, I want to see what kind of results I would get from having the proper RH range for casings.

Thank you everyone for all of your help. This is really a great forum. I'm going to start drilling right now.
