Sounds like they are trying to find a strain that survives in soil or other media for an extended duration. Maybe, since I think I am keeping them alive in soil, I'm just a better grower of BT :-) than the experts. Or, maybe the soilless mix I use or the heated nighttimes or something I am doing is different from the conditions they are trying to deal with. Or, maybe I am believing what I want to believe? All quite possible in my mind. I'll use my strategy until it does not seem to be working any longer. I am nervous about their potential success with creating 'super BT' strains as they are rather broad spectrum and I'm not sure we want them spreading across the surface of the earth.
