Excellent, clear article about this method of seed starting, which I first tried 3 years ago and absolutely am sold on. I agree with Chelle: a huge thumbs up from me.
I'm getting ready to start a few things this year as well. This weekend will be spent trying to decide what to show in my 2-liter soda bottles. I don't usually need as many plants as I get in the milk jugs, so I'm confining mine to the soda bottles. I will add that I never was successful starting poppies from seeds or even keeping them alive after purchasing live plants until I used this method and I now have 2 healthy clumps of Papaver `Brilliant' which delight me each spring.
I presented a program on this method at our local gardening club last winter and have spread the news to neighbors who also love it once they try it.
