I'll show my jugs later when I get my computer's hard drive cleaned off, but I'm using almost exclusively 2-liter soda bottles. Last year I used lots of gallon milk jugs and they worked, but found that I like the soda bottles better, no reason. I've also taped 2 clear CD carousel lids together and used them as a container. I'm poking holes with an ice pick and it does as well as the drill I was using. It's faster and easier than hauling out the drill and the bit tended to skid around on the plastic, too. Makes about a 1/4" hole.
Lots of great info here and I'm way impressed by how organized and methodic y'all are. I have to admit I'm a lazy gardener, passionate but lazy. If it's too involved, I'm probably not going to do it. Plus, I still work full time (who doesn't?) and have limited time available for my gardening, so I want to make the most of what I have. Add in the fact that I'm now 67 years old (yes old, not young), and you get the picture. Oh, I'm counting the months until I can retire!
