Further to the question about sterile soil, I've been doing a bit of searching around for information on how it is done. I've been unable to find anything on Klinsmann bags or their suitability for the Solanaceae, but I did find some stuff. Most of it seems to be about sterilising soil in your oven (very stinky, they say) - for example heating it on aluminium foil-covered trays in a 200 deg F oven until a thermometer in the soil reads 140 deg F, or "autoclaving" it in a pressure cooker. However, there's another school of thought which says that you're likely to kill off the "good" organisms in the soil as well as the "bad". Yet other sensible people said it wasn't totally practical to do it at home, especially if you needed a large amount. If this is at all useful, I can provide some URLs. Cheers, Anna
