Microgreens for the windowsill

I might try  this when its winter - part of my Winter Garden plan, maybe?

This is already part of my winter plan

I even have a compartment in my seed storage box set aside for it, containing some magazine freebie salad mixes, a couple of varieties that are recommended for baby leaves (Bulls Blood beetroot, etc) and any tail ends of packets that I thought would work: lettuce, kale, pak choi, etc

I hadn't thought about growing them on shredded paper, but it makes sense as it's cleaner than compost and micro-greens don't really need any soil nutrients.
