I'm in colorado and its not too cold at night now. Can I just stick them outside now? Or should I train them a little first. I'm thinkin to keep them in pots of course so I can bring them in for winter. I was going to put them in a spot where the sun is full for the first half of the day.

When I lived in Washington, I would gradually introduce them to the sun each spring. Maybe just an hour or 2 of morning sun the first day, then gradually introduce them to more each day. Within 3-4 days, they are usually OK for full sun- unless it's super hot full sun, it which case they sometimes can still sunburn.

Okay thank you! It is getting hot here. That's what I will do.
