Hi. I have a lemon tree, which I won in a Garden Invaders competition 10 years ago. Don't know the variety of it. We lived in Manchester, where it was outside in a pot 24/7. Moved up to Cumbria, where it is colder; therefore, we have to bring it inside for several months of the year. It currently has 4 full lemons on it and over 70 potential buds. My question is, can I put it under a U/V light in a small heated room during the colder months, and if so, what distance would the bulb have to be from it? I am thinking of a ceiling light on a pendant, so the bulb would be about 5-6 foot above it.
