I have a few questions from all of these posts. First, what is the deal with the Christmas lights? Do they keep the plants warm? Does anyone have any photos showing how they use the Christmas lights? I have lots of Christmas lights that I did not use for Christmas. Does it make any difference what color they are? I have both white and blue. Second, in the following photo, I see the little AVs sitting on a tray with the wicks just sitting on the tray also. Can I just sit my pots flat on a tray and add water when they need it? Or do I have to have them up on something like I see a lot of people doing, you know, have them sitting on some type of tupperware container? Can they just sit flat down on the tray with nothing under them? Here is the photo I am referring to.
