Indoor moving to Outdoor?

I started growing a clone in a pretty small cabinet setup about 4-5 weeks ago. Its already almost 18 inches high and nearly hitting my lights.

I know tying it down a bit to grow more horizontal is an option, but I'm located in SoCal and frost isn't really a thing here. Would I be fine to move it outside and let it finish off there in a few months?

The 10 day forecast has a high of 81 and a low of 51 (we're by the beach). Hoping to figure out a fix here soon so I don't have to lose what seems like a great, healthy, fast growing gal.

if your on a 18/6 schedule now, if you throw it outside it might start to flower as you are getting around 13 hours and 30 minutes of light. and most indica strains only require about 10 hours of darkness to flower. but heres the problem. light hours are increasing so proceed at your own caution.
