New green house ordered

[kindrag23]

Hello, During the hotter months I have been keeping my orchids on my front porch on a table. Unfortunately I am afraid they are not getting enough sun. So I will be moving them to my back porch under a moveable green house.

It will be 6ft x 8ft x 6.6 ft. I have attached the picture of it below.

Now how would I need to go about getting the humidity up more towards where it needs to be. Any suggestions for everything else green house related would be great.

I will be moving them to a indoor ext. at my Nana's house with the greenhouse for the winter to help with keeping them warm. That has been re named the jungle room since my Nana got me hooked on flowers as a small child that required being placed inside for winter. I still blame her!!
