yes, ive had many flower and fruit in my basement using led lighting only with no natural light, including a yuzu and mandarin.

I move all my Citrus into the garage from mid November to mid March, never had luck with Citrus in the house. Temps have bottomed out at about 27 F as annual minimums. Been doing this for decades in NJ, Zone 7. You name the Citrus, I got it!

Yes, yuzu and mandarin can definitely flower and produce fruit by a window with a grow light and humidifier—you are practically treating them like greenhouse plants. The key, however, is a cool winter rest at around 5–10°C. Without that colder period, they may not set flower buds no matter how much light they receive, because the temperature change acts as an important signal.

So, if you move them to a cooler place from November and bring them back to a south-facing window in spring, flowering should be much more likely. Hand-pollinating with a small brush is also a good idea: mandarins often manage on their own, but yuzu can benefit from the extra help. In spring, once the first buds appear, use a citrus fertilizer with a good potassium content.
