Me? I have a small non-heated neophyte starter type. I use it from March - November. My house is overflowing in Winter and living room looks like a jungle.
Last winter I kept my Plumeria in the basement. It was my first experience. I did give it a teensy bit of water a couple of times. Our Spring was quite cool and very wet, so it was after Mothers day before I took it outside.
This winter I think I will start some Plumeria seeds - what the heck, Never tried it before. WRT several years before bloom - no big deal. That is the case with many things I grow from seed; e.g. Dietes, Diarama, Siberian Iris. And I also do Bonsai where results are not seen for years.
