When to move them out

[AmyG]

Good Afternoon all and Happy Spring!
Since the frost danger has finally passed, I've been itching to get some of my 'chids outside. I have accepted the fact that I can't have a greenhouse (unless I win the lottery and move!). So, I'll be using my north facing porch as a grow area AND I have considered creating a shade house on my south facing deck. With that being said, I have a few questions:
1. Can I move any out yet? I was thinking the front porch first. Very little (if any) direct sunlight- but not as much heatup as my baking back deck.
2. Will Aluminet still allow for natural air circulation? I plan to move my Vandas and Catts out when the weather gets warmer. but I'm concerned about air flow.
I would love any thoughts and/or suggestions you may have. thank you in advance and have a good day!
