Light lamp set for small lemon
I have small lemon tree (smaller than 2 feet) growing in my unheated sunroom.
Night temp there currently 47-50.
Question: if i put something around container (plastic container currently is in a wooden box) in box and cover plant with row cover for nights, will plant be OK?
It has a number of tiny green lemons and i want to preserve them.
Or do I need to move plant inside? I then will need to set some kind of lights for it because I have only east window.
Can you give me some recommendations for the lamp that i should buy?
