I have a variegated ficus that I like in the location I've place it; however, in fall and winter the sun moves away from the only source of window light and I feel it does not get adequate light. Would it make sense to use a small grow light on the ficus through these low light seasons or would it be better to move the plant to a better lit location (I'd rather not)? Thank you.
Adding some electric light would be an excellent idea. However, forget the expensive "grow lights" - the only benefit they provide is to the bank accounts of the manufacturers. Ordinary cool white fluorescent is actually better. https://www.gardeningknowhow.com/houseplants/hpgen/fluorescent-lighting-for-indoor-gardening.htm
