I have tried several inexpensive ways to grow micro greens and none are very good. Dirt is the worst, as it clings to the plants and is very hard to get them clean. Vermiculite didn't seem to work very well for me. Jiffy pellets worked great, but it's a lot of trouble to get seeds in the little pellets and they are pricey to buy. I was considering trying leftover coffee grounds as I know they are clean and because they are free :-) Any other suggestions for cheap or free medium for growing these greens?

You can purchase grow mats that are specifically made for micro greens, but they might cost more than you want to spend. Many people use a soilless potting mix.
