Suggestions for taking care of orchids while on vacation?

[MrHungx]

Hello

I'll be leaving for a one month vacation in a week. I have approximately 39 plants in my collection and no one to take care of them while I'm gone. I can't set the plants outside because I'm worried about black widows in the pots when I bring the plants back inside. It would be ideal if I can set the plants in someone's greenhouse (I live in San Diego). The orchids are planted in a bark medium and need to be watered once a week. If someone has space in their greenhouse or any other suggestions, please let me know. I wasn't sure where to post this, so I thought that the beginner's forum should suffice. Have a wonderful day!
