How it's grown

The behind-the-scenes version: where the seeds come from, the trays I designed, and what it's cost so far.

Sandwich topped with microgreens

The setup

Indoors near Boston

Zone 6, so growing inside keeps it going year-round, whatever the weather.

Coco coir

A clean fiber from coconut husks instead of soil. The one I use.

True Leaf Market seeds

Microgreen seed bought fresh for each batch.

No pesticides

Nothing sprayed. Cut above the root 8–24 days after planting.
