1. Read the relevant mail before growing the requested cornflowers.
  2. Grow and harvest the cornflowers.
  3. Go to the rooftop between 9 p.m. and 11 p.m.
  4. Place the delivery in the “shady drone” described by the walkthrough.
  5. Wait for Nyx’s response, read the next mail, then visit Nyx’s friend in the Atrium.

Treat the wording and time window as a community-sourced report, not a guaranteed current instruction. The official FAQ reviewed for this page confirms that time runs at a 60:1 ratio and that the rooftop is a core growing area, but it does not document this quest. If the drone or prompt does not appear, check the mail/journal state and exact clock before discarding or regrowing crops.

No cornflower quantity is given here: the walkthrough reviewed for this page does not provide one in its text. The objective still needs an in-game reproduction to confirm the exact quest name, prerequisite mail, crop quantity, rooftop landmark, interaction prompt, time window and completion trigger.
