My girls are outside, spring is early, I may have to cover a time or 2 to protect them from frost, and I may add a light to reveg some that have already started flowering. Go for it, if you use 7 gallon ~26,5 litter cloth pots with straps, they are easy to move. If you have a cold snap move them inside for a few hours, until it has warmed up. Autos luv light up to 24/0, many run 18/6 for cost savings, IDK if it would be cool to put light on them where you are.
