The photo with the dark green leaves is the reaper plant. The other two are the ghost chills. The scorpion looks like the ghosts, so I didn't include a picture of it.
As far as drainage goes, I drilled a dozen 1" holes in the bottoms of each of the buckets, lined the bottom with landscape fabric and filled each with about 2 inches of sand before adding my planting medium mentioned before. I had little, light brown ants that I got rid of by replacing the dirt in the affected ghost peppers. I was sure to keep the ant infested plants far from the other plants until I had eradicated the pest problem before I put them next to any other plants
