Hi Steve,
These days temps never approach freezing point so I can't
offer any useful advice here except to say that desert/arid growing sp. Hips
must suffer near freezing temps at night.
I wonder if you have any Hip.sp. seed available that I could
buy. Q charges are prohibitive so bulbs are out for me.
