I have a Meyer Lemon plant, and have a couple of questions regarding temperature sensitivity, budding conditions and setting fruit and ripening time. I get mixed advice from the internet. What is the lower limit on temperature exposure? Will it bud indoors during winter, under what light and temperature conditions. and if so, is that useless because it isn't likely to pollinate. Once budding and fruit are produced how long does it take for ripening and can that be accelerated? Thanks for your help.

Meyer Lemon can be grown here as houseplants and you can get fruit.
They are self-pollinating, so no worries there.
Normal room temperatures are fine. They need at least 4 hours of direct sun a day, and do best if you can put them outside in bright light during the summer.
The lowest temps they can stand are probably in the 40's, but they stop growing when under 50.
Like many houseplants, they appreciate a higher humidity than most of our houses can offer, so placing them on a saucer of moistened pebbles and spray misting is appreciated.
Actively growing citrus like a high potash (the 'P' in an 'NPK') or tomato-type fertilizer every two weeks, except if your light is low in the winter, when they may rest a bit.
They flower most in late spring and summer, but can flower at any time of year. If your winter light is low, consider using a grow light.
Lemons are green until fully developed and slowly ripen to yellow, which can take months. There is no way to accelerate the process.
