[A counter wouldn't be terrible, but... There's a difference between no sunlight and direct sunlight. It's possible to have a balance between the two.]

Well, a little natural light is good for it, so you could pick a window. You just shouldn't pick one that faces the sun as it rises or sets. I'd worry that leaving it on the counter wouldn't give it enough natural light.

[Thumbing her chin before she continues, she perks up a bit.] Magic might work, too, though that defeats the purpose of cultivating it. It's not exactly the same. I bet it'd be possible to take some of the magic here or maybe a magical item and provide it the perfect balance of light without it being direct.
