As most of you know, we grow outside in south FL, in a lanai under
screening. Last winter, we had some vicious (for here) cold weather.
Unprepared for the duration of it, we ended up carting plants in and out.
The collection is bigger now, and more unwieldy, and 'carting' is not
something I want to do again if we have similar low temps this winter.

Next week, we are installing a 'wet fan' (all weather, out in the rain is
fine) to push air down toward the plants if needed. Now, we're considering
a propane heater. Area is approximately 14 x 18 (all open, of course).
Thinking about a 25,000 BTU heater for the area. Solar heated pool is about
20 feet away, so gives some continuing warmth as well.

Any thoughts? All suggestions much appreciated.
