400w or the sun? Bring her indoors?

I have a fem bubba kush grown from seed, june 5th, indoor then put outdoors end of july, due to my indoor space being unavailable, it is about 3 ft. tall now and has preflowers. Its in a 7 gal grow bag and is receiving direct sun light for about 3 hours a day but only from one side. I now have the option to bring it inside and flower it under a 400w hps in a 6" cool tube. Which id hang vertically. Does anyone think this would be better then flowering her outside? I assume the light change will prob shock her so id prob wait to flower her for a week or two after bringing her inside.
Thanks for any help

nothing is better than the sun.But if u feel like you can give more direct light indoors by all means go on do so.

only 3 hrs + the fact that its only getting sun on 1 side.... id go with the 400 watt

Yeah I think I may bring her in and vert ScOG her since she has already grown to face one side

sounds like a plan good luck with it.
