I have two cuttings that I've been routed since January. I'm seeing that low temperatures are going to be staying above freezing for the next 10 days. That means that my greenhouse can be kept above 50 at night with limited heating expense. I will probably have highs in the 90s and lows in the 50s. Will this be safe for my new plants? By the way, they look like they're suffering indoors.

75F

In pa, we'd have to wait until July for those type of temperatures.

I guess I'll try one at a time like you are doing. I'm worried they will die if I leave them indoors any longer. They have lost almost all of their leaves due to some bug infestation. I sprayed them down with an organic pesticide, but they are still looking sad. Thanks for the reply.

Be careful you harden them off or keep them out of the sun so you don't burn off the leaves moving them to the greenhouse.
Recently rooted cuttings are very delicate and easily shocked. 
It is still March and remember what they say "in like lamb out like a lion".
I have seen March temps plummet to 0F you need to be ready for big weather variance possibilities.
