Indoor to outdoor, help!

I've completely run out of room in my veg and flower rooms. I have 2 plants that are about 5 feet tall that have been in vegetative state since February. They are from my first grow, and I have let them get way too big.

I am considering moving them to a secluded outdoor place to flower. Since it's early summer where I live, would now be the best time to try this?

I know they won't flower till fall, but I need to make space for baby plants soon.
Anyway, let me know if there are any tips for moving a plant from indoor to outdoor. Will my plants adapt to the change, or should I just keep them indoors?

Well, you said yourself you cant keep them indoors, so it lookes like it has to go outdoors, unless you want to cut it in half, basically top it, but completely in half.

This will obviously decrease the size, and slow the growth down a little from shock, but that way it will work.

Or you can put them outside, and they'll get used to it.

They'll carry on vegging untill fall when they flower, so damn, they could be very big by then so keep an eye on the size.
