Harden Off: Seedling Sun Timer

Moving a plant between indoors and outdoors? Harden Off turns today's forecast into one clear move for each plant - how many minutes outside, in sun or shade, and whether to bring it in tonight. A seedling that jumps straight from a grow light to full sun gets scorched. A tender plant left out on a cold night is lost. The safe path is gradual, and the right move changes every single day - a bright clear day means less time out, an overcast day means more, and a cold snap means keep it in. Most people track this with a phone alarm and still lose plants. HOW IT WORKS 1. Add your plant: its light tolerance, where it came from, frost sensitivity, and which way it's moving - setting out, bringing in, a new arrival, or a window change. 2. Harden Off reads your local forecast - sun, wind, high, and overnight low. 3. You get today's move: how long outside, sun or shade, bring it in tonight or not, and one line on why. About 20 seconds to set up. No account required. CORE FEATURES Today's Move One verdict per plant plus the reason - minutes outside, sun or shade, and a bring-in-tonight call, read at a glance instead of guessed. Four Move Types Spring set-out, fall bring-in, a newly shipped or store-bought plant, or a move to a brighter window - each on its own day-by-day path. Weather-Aware, Not a Fixed Timer The schedule bends to the day: shorter on bright days, longer when overcast, paused when frost or heat threatens.
