Sihara,
Thanks for the feedback about my sunroom. It has enabled me to grow alot of plants that I couldn't otherwise grow. It's 18 X 20 feet with a cathedral roof. When all was said and done, it gobbled my entire inheritance from my parent's estate amd then some! But I like plants and birds so it is my little corner of paradise!
I heat the sunroom with one vent from the house and also an electric radiator. Between the 2, I can keep the temps mostly between 65'F and 50'F, through most of the winter - depending on the outside weather. A second radiator does the trick when it's really cold. There is also an AC unit/heat pump, that came with the sunroom, that I can turn on when necessary (it will raise the temp 10'F or more in an hour). So if it's really cold outside - like well below freezing when I go out there in the morning and the sunroom is 45'F, I can raise it up to a more comfortable 60'F pretty easily. And then as I get into early spring, the sunroom is sunnier and warmer - often in the 70s, if it's in the 50s outside, and plants start growing, including the crotons.
I do have a ceiling fan in there that I can turn on to "mix up" the heat (i.e. get the heat from the ceiling down to the floor). But I don't otherwise have any real ventilation problem, at least as far as the plants being happy. Just limiting the amount of heat in generally helps keep the humidity up and the plants happy.
The insecticidal soap I usually use is the Safer brand.
The pink parakeet is a Rosey Bourke Parakeet, as you guessed. I've had her since October (she was born in July). The breeder hand-raised her but I probably would have a friendlier bird now if I got her sooner. She is finger-tame now but not really bonded with me yet. If she sees her cage (inside the house - not the sunroom), she flies right back to it. But I've finally got her eating out of my hand and found a special food she likes (hemp seed) so now I have something positive to offer her - hopefully she will become tamer. I also have doves and finches in the sunroom. The doves get let out to explore the sunroom on weekends and I do have 1 pair of finches that I can release in there (Java Sparrows) that will go back in their cage eventually.
