@aporay – Yes purchased seeds from reputable breeders that I’ve used before. I use rain water for everything as that’s all I have. Yes, they were in a warm place. The tupperware / towel seems to produce much better results that UFO towel (two plates) and it was also a better time biodynamically for planting.
Make sure you keep the seeds damp – don’t let them dry out during the process … they have to stay saturated (but not overly soaked). Keeping the seeds warm (on top of the fridge is a great suggestion by @aporay) will also help you successfully germinate.
