Mine has no temperature control facility. You seem to either use it unplugged or turned on.
Yes I still am unable to find instructions and gardening books only seem to touch the surface of the subject when talking about propagating.
More questions - sorry
1) matting - do I need to re-wet it if it dries out?
2) Should I wipe off any build up of moisture hanging from the lid?
3) When do I open the vents? Is it when seed packet instructions say "remove lid"?
Also how long do I keep seedlings in there after they have germinated. I only have an unheated greenhouse (I am thinking of putting the plastic covers on the cheap shelf units I have in there to provided some snugness instead of bubble wrapping the whole inside) I should imagine that when any seeds have germinated, to whip the lids off and expose them to cold unheated greenhouse/conservatory air would kill them at this time of year.
Sorry about this
