The followng is what I suggested in the Newbie section of this forum where you had the same question:
Depending how large of an area you are talking about, maybe get a dozen or more of your best friends that you can trust with your life (would take a bullet for you) and have them help you comb the area. I would have everyone lined up about so many feet between each other at the beginning of the woods and then move slowly forward while searching the area around them. This should cover a lot of area in a short time. Hopefully before you run out of woods, you will have located your plants.
Good luck and post a pic of the plants in their outdoor living environment when you get a chance.
