Best Temp?!

what is the best temp to keep incubation at (I understand that it states in the FAQ 86). I want to know what everyone keeps theirs at and not just a set number on a sheet, I want real data!

Room temperature, anything good for humans is good for them. I would say 68-75. If you build a TubinaTub incubator high 70's to low 80's is good but it's really easy to fuck shit up using an incubator unless you build it well and keep an eye on it tub in tub incubator
PF cakes and syringes likely have contams that just never end up making it. Sterilization isn't complete it just gives us a window. So if you're doing anything but agar work a incubator can speed up contaminants. Even grain jars sterilized at 15PSI for 90M have some contamination in them that could eventually take hold, it just happens that the mycelium will over-run them before they ever have a chance when done properly

your alternatives are way off. I would never go over 80F room temp.
the search function is your friend, buddy!

right now i have a rubbermade and it has 7 jar in it and the lid is shut under the box is about 5 layers of blankets and then under that is a heating pad, it stays abot 80-82. i had it set to 86 stable and i had two people tell me to lower it. on the other hand i have had people tell me the best way is to keep it at like 91?

90s is way to hot. The growth is actually slower than room temperature at that temperature
Your setup is garbage , sorry to be so blunt
Colonizing jars make their own heat so chances are the interior of your jars are way to hot. Blankets and heating pads are the worst way to go for incubators IMO.
Make a tub in a tub get an aquarium heater that can be set for a specific temperature, Water and the air stone help make circulation and evenly heat.

again, make a search. search for: heating pad + good and then heating pad + bad.
see what gives you the most results...

That chart above is bogus, period. I have tried dozens of times to duplicate it and it can't be done. It was apparently made by someone who did ONE grow with sloppy note taking, and sent the results to paul. Growth is much slower in cold temperatures until you hit 69F, where it speeds up quite a bit until about 75F, where it remains 'flat' until 81, then is flat again until 83, where it falls off fast beginning at 84. By 'flat' I mean there is no discernible increase or decrease in rate of growth within those ranges. Jars will colonize as fast at 75F as they will at 80F. I've proved this time and time again with every strain in my collection. Growth also falls off rapidly above 84, and this is why so many new folks have problems with incubators set at 86F, and jars that 'won't colonize'. The figures I give are substrate temperatures, not air temperatures. The temp inside the jar is 1 to 5 degrees higher than the surrounding air, depending on where in the colonization cycle the jar is. The heat produced falls off fast as the jar approaches full colonization.
If you live in an igloo,(or near the waterfront) by all means build an incubator, but keep it in the normal room temperature ranges for best results. I see no reason to set one above 80F, and lots of reasons not to. Here's a picture of one of my shelves for colonizing jars. The substrate bags are there because I ran out of room on the other shelf. These are in a room at normal room temperature, and exposed to light nearly all day. I don't even put the pf jars on a top shelf where it's warmer. Of course, I had a good teacher on how to make them up, as everyone will soon know.  RR

that's way to hot mycelium growth stalls at temps just above 80 while bacteria thrives. I try not to let it get above 74. Remember the inside of the jar is wormer than the outside.

what is the difference if i have heat coming from a heat lamp set at the same temp in water over a heating pad under blankets. the pad isnt coming in direct contact with the jars so there is no way that they can dry out. ( unless i remove all the blankets and stuff. it sound like the same set up with water instead of blankets.

and if all of this is the case what should i do? take them out and put them on a shelf, keep them in, lower the tempm to 80 i just want the best for what i can do. keep in mind this is my first grow.....

Water has a higher heat capacity/ heat buffering. It will keep your jars in the range way better than the heating pad will. The jars go over temp or under temp the water has more "thermal mass" so it will bring the jars down to 80 or keep them at 80. The heating pad on the other hand has lead most people who have come here and posted about trying it out to failure. The temperature readings are inaccurate since you're reading them between blankets and glass. Chances are you'll stall or fry your mycelium. It also takes a very long time for the heat to homogenize since air has a low thermal mass compared to liquid. Either way you would be better off putting your jars on a shelf. The inside of your jars is usually about 3F warmer than the temperature outside of the jars too. In a tub in a tub incubator that excess heat has an easier time escaping keeping the temperature more true to what you would like it to be.

even 80 is to high. at 80 the internal temp is probably closer to 85 witch will stall growth. just put them on a shelf at room temp (high 60s to mid 70s).

what did the "heating pad bad/good" search reveal? I'm trying to teach you how to fish. Don't fish with rocks.

with a tub in a tub full of water the waters thermal mass helps keep you in check.
think about this 40F water and 40F air. You can go outside in 40F air and be a little bit cold but take a bath in 40F water and you'll be really cold. The water conducts and holds heat better. So even if your TiT incubator is set at 79F if your jars go above it will help keep them at 79F if they go above or below that temperature way quicker than air or a heat lamp will. Heat lamps also have radiative heating so the air can be cooler than the surface the light hits and give you false readings that way too. The jars in a TiT don't actually touch the water but the water still has quite a lot of "thermal power" on the inner tub.

I see your point. I just think incubators are un necessary hassle. room tem works great my jars colonise in no time just sitting on a shelf.

yea, no need to speed things up, patience is key. You're just going to ruin things thinking you need to get it done 2 days quicker. Screw with incubation once you're running something like 5 monotubs in rotation and have some experience. .02C

No need for incubating anymore, global warming ftw.. Last winter the temps here were around -5F -> 5F (-15C) while this year it's closer to 50F (10C)

I wish it was that warm here. it's already dropped bellow -30c here.

everything I read is contradictory..... i have had these in the incubator for a week now at 81 and this is what i have . should i keep them in or take them out.

Dere is no argument, the best temp is 81'F
..
..
FOR ME. It's all a variation of your environment and your practices.
My jars all incubated between 79-81'f and they were faster than average, I had around 12 jars, each jar g2g'ed into another 8-12, I had one that I wrote down as possible contam but it survived and fruited an average of 2-3 flushes each bulk.
