[Plant-education] looking for red/far red sensitive lettuce seeds

[Gini Berg]

Does anybody have a source for (or a big pile of) red/far red sensitive lettuce seeds that I could use for a classic phytochrome teaching experiment? Mine are old, and now either all germinate (regardless of light) or fail to germinate (ditto). I've tried again from the same source, but they all germinate now. 

Thanks.
