Rising temps a sign of colonization increasing?

I have had 5 trays of Hpoo spawned with WBS and BRF cakes in my incubator tub for about 5 days now. I don't have any heaters on them at all. I have noticed that over the past 2.5 days the temp rises about .7-1 full degree a day. It's right about 79.5-80 inside the tub. I don't really like checking them too often but lately i have been peeking once a day.
My question is this.
Is steadily rising temps sort of an obvious sign that colonization is picking up?
Im hoping they are done by then end of the weekend and ready for a casing layer..

yep, rising temps = increased metabolic activity. there's something alive and eating in there. hopefully its mostly your mycelium.

well i hear grunts every now and then coming rom inside ut who knows...
keke,
I kinda figured as much I just thought i'd ask. im just gonna leave them alone until saturday then open up up for another peek.
(rofl the 3 I made with coir as the substrate the day after i made the hpoo ones are already cased and about to go into the FC tonight, even the 1:5 one..)

wish i had the same luck at the moment, i found cobweb in my 80% or so finished coir monotub today
figures after all last weeks' discussion i decided to "properly" pastuerize it and see what all the fuss was about, and thats what i get... hmf. (not necessarily blaming one thing on the other... suppose i was due... but i ususally PC or nuke, and this is the first time ive _ever_ had a problem with colonization)
fu, cobweb

You still need gas exchange. If all your trays are in a tub, the excess CO2 that seeps out needs a place to go. You'd probably be better with your trays on a shelf. At least fan when you open the tub. RR

I had killer luck with using h2o2 full strength on my cobwebbed poo. killed it in half a day..

i was still providing gas exchange (so i thought, in sufficient quantities at least), i know cobweb is a sure sign of stagnant air though.
havent had the problem in the same tub with the same methods before... not blaming it on any one factor, contams happen.
it was a really small bit... kinda like a half circle against the wall less than an inch across. took it out with h2o2 right away. sprayed the rest of the surface down too. its already fluffing back up (fluffing up white and mycelium-like, not grey and cobweb like ) so i think its gonna be just fine. its so close to done if theres no signs of the cobweb back tomorrow its gonna be cased and written off as a small bump in the road 
edit: oops, you meant to him, not to me the threadjacker. 
yeah, definitely provide for gas exchange or the cobweb will be more likely to get you too!

I hope you have a means to COOL those trays down, IF NEED BE.
If the internal temperatures go to high, fermentation will set in.
I incubate h/poo, or compost trays at 70 - 72F.
The reason being, the microbial activity in the trays. Will generate 10 or 11 F, by themselves.
So, incubator temperature is about 81F, heated by the trays, themselves.
Which is FINE.
Conversely, if your incubating at 80/82F?
the trays can heat the incubator to 90/93F.
Which is NOT FINE.
To high, they cook themselves by fermenting. Fermentation creates alcohol.
Alcohol + mycelium = DEATH. 
Wire racks allow air to circulate 360 degrees around trays. Trays sitting on a SOLID SURFACE. Are insulated, on the bottom. Which will cause the substrates internal temperatures to RISE.
If unheated, your incubator temperatures rise past 86F.
You had better find a way to introduce cool circulating air, into the incubator.
Otherwise, you may suffer a deadly heat spike .

well i keep my house pretty cold, do you think they would keep themselves warm enough? My house stays around 70-73 segrees all day.. If so i may just move them into my closet up on a wire shelf with a black trashbag over them.. Then the CO2 could freely seep down through the wire rack. what do you think about temps?
EDIT: after reading your post trippin it seems as though i should just move them into my closet.

Couple things.
I cling wrap my trays. I secure the cling wrap with painters masking tape.
I then either make a row of pin holes in the cling wrap.
Or, small straight slit's, with an exacto knife.
I then cover the pin holes, or slits with micropore tape.
A gnat, or horde of them cannot get into trays, set up like that.
The slits, or pin holes allow gas exchange. The micropore tape over then is both a gnat, and contam barrier.
I then crumple aluminum foil, and lay it over the trays. Doing so allows gas exchange, while minimizing exposure to light.
The incubator is in an air conditioned controlled area kept at 72F.
I monitor the ambient incubator temperature.
If the internal incubator temperature starts to rise, near/above 80F.
I induce cooler room air into it, via PVC pipe, with a small squirrel cage fan.
 Incubator doubles as a fruiting chamber. 24 cubic foot upright freezer.

I do the same.
wire rack, a/c room, 74-77 degrees in there.

jeebus. All high tech and such. Nice setup though. Well i didn't really think to go that far into it. I think you are right that they were probably getting too warm since the ambient temp inside the tub was near 80. I have my trays covered in one layer of tightly fitting alluminum foil with about 6 holes in it then i have a crumpled foil on top of that with a loose fit to it. I then covered them in two trash bags to retain a little wamrth and keep anything else sorta out of it. I seem to have a fairly contam free household. I keep it clean and spray it down often too. hopefully the foil i have will be good enough, especially since they are about 60% already. Anywho heres a pic of my ghetto incubator.

They are currently about 60% colonized after about 4 days i think..
heres their next home..
