| I seriously doubt if you will have damage to your plants but if you do it will show up as leaf damage, either yellowing or darkening.
I live in Central Florida and grow in a greenhouse but I experimented by putting duplicate plants outdoors where they were subjected to temperatures around 35F. The plants were Cattleyas, Dendrobiums and Phalaenopsis. There was no damage to the plants. You must make sure that they are in an area where it does not frost on them. |
