Joanne - I should have explained that I also have the bubble wrap in my little gh and wasn't sure if that's why my tomatoes took off the way they did. I had good luck with some seedlings my DD gave my last year - potting them up and burying them deeper every few weeks. Had great roots - just a lousy summer for growing them (wet, cool and cloudy). Maybe on cloudy days I can stick the plants under the lights?
