For fastest payback, peas grown for shoots are hard to beat β€” 21–28 days in trays, cheap field pea seed, and you can flip beds fast; keep airflow up to avoid greenhouse damping-off like in the sanitation thread. > discussion delves into the key attributes that contribute to success in the field.

If you want a cover legume instead, berseem clover pays back N in about 6–8 weeks, but , it sulks on cool nights β€” what temps are you working with?

If you want even quicker cash than pea shoots, try fenugreek microgreens β€” 7–10 days to first cut, bulk seed is cheap, and the flavor sells itself. Tying into last week’s sanitation note, pre-sanitize trays and bottom-water to dodge greenhouse damping-off. @eholt92, have you ever gotten a clean second cut on fenugreek or is it strictly one-and-done?

I’ve had the quickest payback with lentil microgreens, @tgriffin60 β€” 8‑hour soak, about 120 g seed per 1020, and cut at 7–9 days; keep temps under 72Β°F or they turn bitter. Small caveat: they’ll stretch if you overstack or shade too long; ever tried pitching them as β€œbeluga” lentils to chefs?

Cowpea microgreens have been my sleeper legume for fast payback. Soak 6 hours, sow about 180 g per 1020 with a 2‑day stack and cut at 8–10 days; thick yield and a nutty, β€œblack‑eyed pea” note chefs like. Hulls cling a bit β€” quick brush before packing fixes it; would that fit your buyers, @jgreenwood45?

But mung bean shoots have been my fastest payback legume β€” soak about 5 hours, keep them weighted and dark for 3 days, then give low light and cut around day 6–7. Tying into last week’s β€˜sanitation methods’ thread, a 200 ppm bleach rinse on trays cut my off-odors and slime to zero. Only caveat: hulls can cling, , so a quick mist right before harvest helps them slough off.
