Hey guys, I just received a cutting of Rokko 'Exotica' the other day and I was wondering if I should treat it as a lowlander while rooting or a highlander? My highlanders get very cold at night (like 45F) so I am thinking maybe I should leave it with the lowlanders? I know it is Thorelii x Maxima, but I have heard that Maxima takes over in the hybrid? Also, while on the subject, should I treat Thorelii x Mixta as a lowlander? I know it has a good deal of lowlander parentage, but I believe it was being grown outside as a highlander. Finally, I have some cuttings of various highlanders, but I was wondering if the cold night time temp drops will be detrimental to the rooting process? The daytime temps fluctuate between 70-78 depending on how warm it is outside. Thx for the help.
