How fast do I get my plan?

Three steps, three minutes. Type your location, measure your bed, click the veg you like. I do the rest.

Free: one bed, full annual plan, PDF export — free and no account needed. Pro (multiple beds + weather + garden calendar + push & email reminders): €4.90/month or €39/year. Premium (with AI coach Stachi): €9.90/month or €79/year.

Does it work for a balcony planter?

Yes. From a 40×20 cm balcony box to a 3×1 m raised bed — same three steps, same outcome.

Do I need an account?

Not for your first plan — creating one works without signing in. You'll need an account once you want multiple beds, your plan on multiple devices, or weather reminders.

Stachi's tip

Spring onions are the fastest onion option: 60-80 days seed-to-harvest. Sow every 3-4 weeks for continuous supply. May seedlings from the supermarket work fine too.
