I didn't realize it was under the sun. Then you can forget what I wrote. Nothing further away than the sun, eh? You can switch to indoors, but what lighting are you going to use? I'd say get a sodium light. It will continue to grow during flowering, so you might let it get about two and half feet tall or so and put the light on a 12 hours on, 12 hours off cycle, to get it to bud and flower. Hope it's a female.
