Lauriebeth, I would put them outside now. Keep them in those pots until you see roots appearing. Then pot on again. I would expect them to be very much bigger by mid summer.
If you think it will be frosty overnight drape a fleece over them.
your lavendar will not enjoy being in the gh now
if your plants have filled a 1 litre pot by the end of August I would plant them out
a lavendar hedge is lovely. I have a 40' edging to my veg patch....the smell when in full flower is "scentsational". .......oops! I'll get my coat
