Of course, my plants are well acclimated... they have been outside for years. If I acquire a plant in the fall or winter, that should be cold-tolerant, I often pamper it indoors until spring when I put it outside, and it then has the full cycle of seasons to acclimate. If I know that the plant has been grown under conditions similar to mine, no problem. But if it has been greenhouse-grown, or I don't know its history, I will be a little more cautious,
C. dowiana is another story... that species is a warm grower, probably should not go much below 18 deg C (65 deg F). Hybrids where C. dowiana is dominant need the same treatment.

Thank you. The purpurata hybrid has been with me for more than 6 months, so my frame of reference is now my home haha. I'm thinking of putting it outside and if temps go lower than 12ºC (53.6ºF) or so, I'll bring it back. The amount of sun it will be receiving will be slightly greater than the one it is receiving currently, so it would just mean a step further on its progression to full sun. I definitely love monster plants (and especially cattleyas) so I am aiming for that
Cheers,
