Go in the attic and install a 2x4 or larger board from joist to joist and hang your lights from the board. Drywall is not meant to hold more than a few lbs of weight, and I can tell you from experience that when your lights and ceiling fall on your plants, your not going to be happy! My advice is to make it bullet proof...if I can't hang from it, neither will anything else!
