i would put them in the greenhouse to harden off.sweetpeas dont actually need heat to germinate but they will need to get used to the temperature change,ive only just planted my seeds,outside,i couldnt be bothered in october.

Thanx you've put my mind at ease :-))

i have a lot of sweetpeas they are about the same size as yours ,grown indoors but am putting them in greenhouse tmoz as getting fed up of all plants in spare room now,however they do need re potting so think i will keep them in greenhouse a week or so before re potting good luck with yours,:o))

I have my sweetpeas seeds planted in the inside of toilet rolls [the tube] so all i do is plant the whole lot in the soil when ready, as the card tube is degradable and saves repotting !!Thanx :-))

i also used them for mine but they started to go mouldy ..dont know why so re potted them ,maybe the room they were in wasnt warm enough..:o)
