I saw this on Hometalk:
The original post was on 3 Peppers. One important thing that wasn’t mentioned is lack of drainage. Clearly punching hole in the bottom of these cute pails will result in cute puddles of mud on the windowsill and floor, so I recommend not doing that. The author added rocks to the bottom of the pails “for drainage”, but RLGS readers will know that’s counter-productive. Just be careful how much watering you do, and test the wetness of the soil by poling your finger down a few inches.
