young plants out and a frost expected!!

I have some plants that I just put out Friday and now there is an expected frost Monday. They are Sour Diesel plants that were started under cfls and they are very bushy. Probably a foot tall and wide. Just wondering if the frost will damage them and to what extent. . The temp is supposed to be around 30. They are a ways away from my house so I guess my question is should I chance leaving them or should I make the trip and cover them for the night?

cover them or do something, otherwise they will probally die if it gets that cold and a average/strong frost occurs.

if your going to leave em outside frad yourself a bunch of empty plastic like 750ml and cut in 1/2 cover your babues with the twist off part ontop and have the cap off..
