my plants were hit by a light frost last night. i was just wondering if they will still be okay? its supposed to be 75 degrees today, and i was wondering if i just stuck cut soda bottles over them this evening to trap the heat, if they would be okay if there was another frost tonight. the plants aren't little seedlings, they are all about 12"-16" tall. any suggestions.

If they're that big and they've been outdoors, I'm betting that they should be just fine. If they were raised indoors, then stuck outside just in time for frost then I might be more concerned.
