Ernie - Thanks for the response. Uh, my gh is nowhere near the size of your's. Bet you have a HUGE tomato crop with all that space. I'm fighting aphids in my gh at the moment. Ugh. Good thing I'm not sqeamish since I mostly rub them off with my fingers. Just when I thought I had the aphids beat by not overwintering their favorite plants, they come in on something else.
