Thanks. I know from experience montanes can withstand temps down to fluctuating daily from 45 to 55, with occasional brief drops as low as 38 for a few hours. My situation is that indoors it stays 62 to 72 and the garage is the cold temps above. For me it's one or the other, I can't get inbetween. I have had reasonably good fertility from the garage temps, I am just wondering if I could get better with the indoor temps. After all zonatas live in Malibu Canyon and pyros actually live quite low in elevation in some riparian canyons. I will report what I find out.
