Seed sowing experiment - Hotbin

I've been wondering whether I can start seeds (in pots) inside the Hotbin, using it like a heated propagator - or a Hot bed.

Today, I've sown 6 mangetout peas in 4 identical pots, filled with the same compost mix (mostly coir). 
Pot 1 is inside a sealed plastic bag, inside the Hot Bin  which is in GH 1
Pot 2 is under a clear plastic supermarket tray in GH1
Pot 3 is uncovered, alongside Pot 2, in GH1
Pot 4 is in my bedroom!

Which one will germinate first?

1. Hot bin
2. Bedroom.
3. covered
4. Uncovered

Basically I think I agree with SC, but just to be different I'll say:

1. Bedroom
2. Covered
3. Hotbin
4. Uncovered

No signs of life yet but the next day after sowing, the Hotbin bag was hot and steamy.

Do you know the temperature in the hotbin? I think it may get too hot.

I do know the temperature but can't remember what it is!
According to the Hotbin site, Hot composting temperature is 40-60C or up to 70C.

First to show green shoots is Pot 4 in the bedroom!
I can see signs of peas pushing to the surface in all the other pots. Its going to be a neck & neck finish.

Ooohh, maybe I was a little bit right 

Next up was the Hot Bin pot. The shoots are white, from being in the dark.

There was very little difference between the 2 pots in the GH, one covered, one uncovered. They still haven't really shown any green shoots.
