Try to find seed peas if you can.

I also used very dilute ethanoic acid to give another colour when 'calibrating' the indicator - it gives a lovely bright magenta colour. Also if you use bungs containing thermometers, you can observe the heat energy given off by the germinating peas as they respire. JES, London (UK)Anonymousnoreply@blogger.com
