In Florida we have temps of 75 during the day and 38 at night. This happens for 3 or 4 days then its back to 60 at night and 85 during the day. We usually end up bringing plants in and out, in and out. Its a real pain. This year I used an enclosed porch area for all my plants that don't really enjoy weather below 55.
I used folding 4 ft tables, under the bed size storage bins, Cloths rack for vanda like hanging orchids, and fencing trellis style set up like a construction horse for mounts. I have four 65W grow lights with clip sockets that I can move around easily. Plus 2 bulb overhead.
This is working out really well, I have my gallon sprayer for watering and by using storage bins I can easily water without getting making a mess. Windows for extra light or opening for air, I can also set up heaters if necessary.
So far I haven't needed the heaters, 39 outside but 60 inside. Outside I have two shade houses that I have drop down plastic curtains for wind protection, which works for everything else. This set up made it so much easier this winter, One time in and out.
