What are the best growing media for microgreens?

I have read about a number of growing mats and media for microgreens, but find myself unsure what to choose. Is a hemp growing mat better than rockwool or plain soil? Has anybody tried and tested a few of these?

Hey Charissa,

I would go with hemp mats. Hemp is environmentally friendly because of it’s ability to biodegrade. Rockwool on the other hand, is a material which can actually cause some eye and chest irritation when working with it - not ideal in an indoor setup.
