Help needed with outdoor lighting

[weednoobie]

Hi, I'm planning to plant a sativa-heavy auto on my balcony. The temperature at my place is between 23-31 degrees Celcius. It's windy enough.

The only problem is that my balcony doesn't get enough direct sunlight. Would it make sense for me to place a supplement light for my plant?

If yes, what intensity light should I choose? and what type should I go with?

How much is not enough?
It is a strange question. Lighting up an outside pot plant is advertising your pot plant.
If you want to keep your plant growing outside, you need grow lights. You'll have to figure if you want to advertise in the blurple of LED light or the white light of everything else. To keep your plant from flowering you just need bright light. A couple fluorescents will work.
