Microgreens and sprouts are the highest-value crops per square foot we grow. The seed quality is everything โ bad seeds mean low germination, mold issues, and wasted trays. After trying multiple sources, Mumm's Sprouting Seeds is the one we keep reordering from.

Why Seed Quality Matters
You might find cheaper seeds online. The problem is that low-quality or untested sprouting seeds have inconsistent germination and higher contamination risk. With microgreens, you're eating the seed coat โ food safety matters. Mumm's tests every lot. That's why we pay a little more and don't stress about it.

If you're growing microgreens for the first time, start with radish. It's the fastest, most forgiving, and gives you the clearest feedback on your tray setup, watering, and light. Once you nail radish, every other variety is easier.
For a simple beginner kit you'll need:
- 1020 trays (solid bottom + mesh bottom for drainage)
- Coco coir growing medium or a good seedling mix
- Seeds โ start with radish and sunflower
- A spray bottle for watering
- A fan for airflow
- A light source โ a south-facing window works, a T5 or LED panel is better
Total startup cost under $50. First harvest in 7 days. See our full microgreens growing guide โ
