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

Plant onions as sets, don't sow — sets are far easier than seed. Plant March/April, harvest August/September. Let the skin dry well before storing — otherwise they rot in the pantry.
