chilli seedlings help please..

Hi all i have some chiili seedling i will be moving to my cold frame soon. I was intending in planting them in my 1 meter tall raised bed but am now concerned they may be to exposed. Also if they are suitable for beds could anyone tell me the spacing needed between the plants and likely heights please. I have been looking eveywhere with little success and dont want to ruin my plants....
They are
Trinidad scorpion
scotch bonnet
choc habanero
bhut jolokia
red devils tounge
rocoto red
Thank you all greatly for any advice you can offer, i am hoping to fill a whole bed with plants...

inside mickeyboy!! especially with the choc haberno, great in a big big tub in a ghouse

Hi Mickeyboy,
I've managed to germinate several varieties of chilli seeds this year including some fairly hot ones but for the life of me I cannot get my Bhut Jolokia to germinate, I've tried about thirty seeds using various methods. Any advice you can give me to start them off. I know it's possibly getting a bit late now but I'll give it a go.
Maybe they wee just duff seeds

I've got some chillis too and they could do with more light (currently on window cill).  Would they thrive in an unheated greenhouse or do they really need extra heat ?

Still too cold round here - your looking for a constant temperature of +10degrees MINIMUM, depending on the seedlings you're either going to kill them or stunt their growth lower than that.

Mine will stay on the window cill for 2-3 more weeks with foil behind them.

The foil makes all the difference to light levels

Hi there to be honest i had no probs... i germinated them in an air tight container sandwiched between 2 damp bits of kitchen roll. Check every few days to make sure they havent dried out(if so re wet to piece of paper) or rotting(remove lid). Then as soon as they geminate transplant to a chep b and q heated propergator for a while, then transplant to windowsiil with foil covering back and sides. I had a %100 success rate with all my chillis using this method
Hopes this helps... oh the trinidad scorpion i planted 5 seeds into prop and they all germinated aswell. Just kept moist not wet..
Hope this helps..

Thanks for that Mickey
