Yes to both. You will need some extra lighting

Thanks. It will not work then. No way to have extra lighting. Of well. The plugs are at their limit everywhere,

This is the 1 of a few I have

Switched outlet strip

u must find a way to make less  cordage  for your safety and when to many cords are plugged in it can be a  fire hazard  how to do that I will not say   for I know not your house setup

NO cords for lemon tree.

How big is your window? I have a 15ft wide by 7ft high picture window in my living room where I grew two kumquats with only natural light for about 2 years. I only had to add lights recently to contend with a massive cherry tree that the developers planted when they built the place, well that and the fact that I needed more space as my number of plants has grown. It is possible there are just a few factors to consider such as how far north you are, how warm the window gets, etc.

Of the two, I much prefer limes, I find them extremely prolific.

 41 North (zone 7a/b NE coastal)  that is a good thing   but watch out   they could cross with each other

I live in southern NH and have both Key Limes and Meyer Lemons which I over winter in my house. They are kept in a room with large 6' by 8' east facing windows. They over winter fine. The Key Lime produces well but the Meyer can be challenging depending on when I can set them outside. They are usually outside from mid-May until the first predicted frost around early to mid-October.

This year for the first time, I sent the largest Key Lime tree, an avocado tree and a Mission Olive tree to a commercial greenhouse for overwintering. They grew too big for my house. I will be interested to see how they faired the winter.

  it sounds  like  you need  to build your own green house   so you  won't have to send none of your trees to some commercial green house for the winter

Howard,

I had a greenhouse for many years. Unfortunately with the cost of home heating oil or electricity to heat the greenhouse, it is far less expensive for me to send a few tree to the commercial greenhouse for the winter.

   Yu can  find some alternatives  like using  barely painted black full of  a water on the sides
