are my tits too hot?
    #4165816 - 05/12/05 09:26 AM (18 years, 10 months ago)

So I am just starting and is wondering what the acceptable heat range is for germination.
Lastnight I injected some spores and dropped the jars in my TiT. I found an awsome digital food thermometer (the long metal probes with the fat end where you read it) and i basically just poked a hole in the top of the TiT and slid it down and left it there. The issue i found out this morning is that im only reading ~10" down from the top while having a 20gal tub that is probably 2' high.
sooo.. the thermometer is reading 81-82, i decide to see what the water is reading and its like 92. I would imagine that the jars sitting at the bottom werent quite that high, but they were obviously in the 82-92 range. I remedied this by sticking a stryrofoam box in the TiT and dropping the jars in that till i can get things fixed. maybe ill line the bottom with bubblewrap or something to insulate the sides of the tub from the jars.


anyway.. what kind of temperatures are UNACCEPTABLE during the germination phase? is that first ~12 hours of potential 92F temps anything to worry about? Any comments/tips about TiT temperature calibrations and what not would be cool too.

lol i've never clicked on a thread so fast before

to your Q though, get the temp for jars to about 80-82... the 92 for 12 hours won't hurt but myc. thrives best at 84-85

:laugh:

alright sounds good.  what temp will kill spores? and how about the temp that kills myc?  Ive actually read that cambodians (one of the 4 strains i have in the TiT) LOVE heat (like 93+ while fruiting http://thehawkseye.com/cambodia/cambodia.html)  so i wasnt TOO concerned.

As long as your water level is high enough, the space inside should be about the same temp. You're good :smile:

I think anything above 95 degrees is bad news.

im going to get a thermometer that lets me measure the surface temps of the jars and the bottom area of the TiT.. but that doesnt make sense.  I do have like a good 8" of space between the bottom of the 2 tubs but if the water is at 91, how would the bottom of the tub and anything touching it NOT be influenced by that? There is no way you would get a 10F drop just from the 2mm plastic that the tub is made out of.

Are you are filling the water all the way up the sides? Are you worried it's too hot in there? If so, turn the dial down on the heater.

if you need to help get contact between your two tubs (because the top one is floating too much) put something heavy on top of your 2nd tub. i've got my PC and a box of oyster shells weighing mine down.

also when you fruit in general you'll want to drop temps into the (mid) 70's

Most people run their incubators way too hot, low 80's is where you want to be in my opinion. Anything much above 85 can slow/stall growth and result in nasty meta waste from your substrate.

Low 80's as in the thermometer reading low 80's? Maybe mine is too hot....

doesn't it also depend on how much substrate you're incubating, the amount of myc growth, and the type of substrate?

as in, a bunch of highly colonized poo will generate more heat than 2 relatively uncolonized BRF jars....right?

Yeah, low 80's as in the thermometer reading low 80's. Don't go by the dial setting on those aquarium heaters. Take the reading from the bottom of the jars, not the top. It can be 5+ degrees warmer on the bottom than the top as well.

deathbychimney large containers of poo will generate a lot of heat, yes. I like to incubate those around 77-80 max.

I like my incubator at 81 degrees F.

and I get very fast colonization times.

hrm. yea it looks like ill definately wanna get some readings from the bottom them. For now i think the styrofoam box will isolate things quite a bit from the bottom and sides of the tub. that little box held some icepacks in it for 4 days and they were still solid!!! i am not using the styrofoam lid though :P

yea right now it is kinda floating, but i dont mind as this gives a visual indicator that i still have water in there. I am thinking of maybe throwing in an inch of dry geolite to the bottom (since i have extra from my PMP) that should lift the jars up a bit from the bottom and give some nice insulation along with some weight

hrm.. i bet i could extend some wires from the thermister portion of my thermometer might be able to get some bottom readings that way without always opening the lid
