Tell us about yourself!
The chemicals from the packaging make me nervous. The soy milk is not sending micro-roots into the container like the sprouts can so it's going to be clean. Plant roots go searching for soil chemicals by their genetic nature and function like scavengers. I prefer to use class (like Pyrex) dishes and lab petri dishes since they are inert and chemical free. Once you make that small investment, those are good for hundreds of sessions.
