TEMPERATURE SWINGS

Besides making jars breathe in and out, are temperature swings bad for myc.. I have my jars in a room that isn't insulated and can go from 57f at night to 87f during the day. If I keep my heater on at night(all night on full blast) I can keep it up to 65f or so. The question here is how bad is it for the myc. to have these drastic temp. swings?

I wouldn't say it's bad. No it's not ideal for mycelium growth. Some strains are more aggressive than others but incubation should stay high 70's to low 80's. Puttin them in a fridge will bring mycelium to a near standstill. So 60's will affect the speed I would say. But not the final product.

I would strongly suggest stabilizing your temperatures a bit. Swings between 65 and 75 degrees fahrenheit are ideal Many will tell you that an incubator is outdated TEK, but you are prime for one, if your temps are swinging that much. Just try to stabilize your temperature right around 75degF; but try to avoid going much higher than that.

Not sure what you have heard, but temp swings are typically good for growth, yes it provides gas exchange and mycelium will grow faster. I think you are going a little bit low though at 57, you may want to try to keep it from getting that cold, It won't hurt the mycelium, but it will slow it down. I keep my jars at 85 during the day, and about 70 at night. Most say to keep the jars at about 80 to 85 degrees, although it is not really as important as it was made out to be a few years ago.

That's why I said wouldnt be bad but not Ideal.

Ok, not understanding why you quoted me 3 times... but I am saying it, in fact, is ideal to have temp swings, but maybe just not as low in the night time.

Temp swings are fine, and in fact good. If you feel the temp is swinging too much, simply put the jars in an insulated area to moderate the swings a bit. Incubators are for premature babies and for kids to hatch chicken eggs as a science fair project, but not for mushrooms. RR

No one is getting mad buddy, just didn't get the quoting me three times in a row there, I am assuming it was a mistake. I only thought your comments below were in regards to temp swings in general, which is why I was disagreeing.

And I'm new the site, trying to figure it out so I apologize for the triple quote. But if you need to pull out facts and italicize your words to sound intelligent go for it, ill pretend I'm offended to make you feel better

here is one more thing I was wondering, is there such a thing as too much humidity for fruiting? if I have a fruiting chamber that I decided not to drill a bunch of holes in like the sgfc and put a sonic mist humidifier where it would blow straight in would that be too much to leave it on all the time or would that be good? It completely fills the chamber with the "mist" or cool steam stuff, should I just turn it on every once in a while(maybe 4 or 5 times a day)?

what i read on here (could be old and outdated, i dont want to be attacked) that there is never too much humidity for cubes. from my small experience, i noticed the heavier i misted the more irritated my cakes got. the only concern i have is if this thing is putting off a mist that is larger enough to form pockets of water over the substrate, which to me would be like over misting. I would stick to the SGFC. RR may be cynical but is very experienced and i would follow his tek to the t if you want to get a quality yield.

I am going to follow RR's tek to the t for my original 8 cakes but this one cake is my little "experimenter". as far as FAE I think the piping in and the "pumping" of the steam(or whatever it is you see coming out of a humidifier)is coming out the little gaps, cracks and holes I couldn't seal, so it seems to me that the air is being exchanged whenever the humidifier is on because I can really see it coming out(even out of the holes i drilled in the bottom for perlite/water drainage). I had it on for about 45 minutes last night at full blast and it really only got up to 90% rh any way but it did stay at 89% all night so it won't need to be on as much as I originally thought.
