Indoor/Outdoor Grow

If your plant is "hardened" to real sunlight then you could take it outside to get more intense light. Keep in mind that the plant does best with consistent 16-18 hours of light per day. Doing it now and then might do more harm than good and I certainly would not leave it out over night which would mean it's getting a much shorter light period. I personally would not risk pests and disease by going outside. Either grow inside or outside. I would spend the money and get a better light and keep your plant inside where you can control the environment for maximum yield.
