Grow Food Indoors, Guided by Plant Science

Grow mint indoors from cuttings in a 12-16 inch pot, give it 6 hours of sun or 14-16 hours of grow light, and cut it often to stop flowering.

Harvest microgreens at the first true leaves (6-14 days), cut above the mix, skip washing, and chill at 41 °F for up to two weeks.

Light, temperature, containers and harvest timing for growing lettuce indoors, with the numbers extension and research growers use.

Cilantro bolts in heat and long days. Indoors you control both: cool room, 14–16 h of light, deep pots, cut at 6 inches and re-sow every 2–3 weeks.

Microgreens need a DLI of about 9–16 mol/m²/day: roughly 150–280 µmol/m²/s for 16 hours. Here is how to set hours, PPFD and lamp height.

How to roll, warm and count a paper towel germination test, how long each crop takes, and how to plant the sprouts.
