I have that book somewhere, I'll have to see if I can find it. They did all kinds of research on plants and their response to different stimuli.
My semps all had a big dose of love today. Two ladies showed up at my door wanting to see my semp collection. We had the most amazing time, with them oooing and awwwing all over them. I do believe I could see them perking up and following the ladies as if they were sunshine.
Twit, my day is now complete. You are here. You can't begin to know how much I've been thinking of you the last few days.
How are your semps doing?
And I see you have not lost your sense of humor.
