seeds Seed Starting

Hey, THP!
 
     This year I am trying unsuccessfully to grow from seed Aji Panca, 7 Pot Yellow and Primo, Carolina Reapers, Wild Brazil, Black Chiltepin, and Fatalii -- many of these were purchased from Refining Fire Chiles.  I soaked one batch of seeds in a weak bleach solution, and another in a weak tea, both for 30 minutes; they were then transferred into a damp paper towel in a bag.  After 3 weeks or so, the only seeds I had germinate were the yellow 7's and my cayenne cross, both of which popped within the first week.  It is possible I have cooked my seedlings, as the seeds have been exposed to temperatures at least over 90F, but I am not sure, as some sources claim anything over 85F is dangerous while others say seeds can germinate at temperatures over 100F.  My house stays around 68 degrees but can get cooler at night.  I am struggling to find a place in the house that stays consistently warm in the "Goldilocks zone" of seed starting, so any good instructions on a DIY heating pad that maintains a steady temperature would be of use.  I realize this question has probably been asked a hundred times, but please help me with your advice on starting these varieties.
 
Thank you!
 
Unrelated question: is it possible for seeds to survive a dehydrator?

If the dehydrator was set low (95 f or so) than some should be viable.

if its been 3 weeks i would give up. Some people have reported like 6 week germination rarely.
 
My seeds usually take 1-2 weeks max with tea pre-soak.

You're bad dude! lol  
 
Seriously, I have had certain seeds not germinate for many unknown reasons, but when it is a whole batch of one specific species, I conclude that the batch was not viable in the first place. But when a entire group of seeds in my propagator does not germinate (several types), I know it is due to my husbandry techniques. So if this was a mass germination failure, it was due to something you did. Heat possibly, bleach likely.

Whats odd is that the only seeds I had germinate were from the bleach batch.  I suppose some species may be more sensitive than others.
 
Thanks for the responses so far, guys.

I had great luck using a cardboard box and an old strand of incandescent christmas lights last year as a seed starter.  I put a thermometer in the box and started removing lights from the box to decrease the temperature.  I can't remember how many lights I had in there to give the proper temp, but it held fairly steady once I got the number right. I even modified some old shelves to make a much bigger seed starting "tent" and I got great germination rates for my first attempt.  If I weren't in the middle of moving I'd be doing it again this year.

Update:
 
I happily have two little reaper sprouts coming out of a batch I thought dead, so there is hope. 
Patience is a virtue indeed. 
I have also started a second batch of seeds that are sitting on top of my modem at a nice, steadily warm temperature.
