Yes. You will need to print out the QR code for the ticket you wish to gift and physically give it to them. They will then need to bring that printed QR code to the event Registration to redeem it for their wristband.
You may change the name that appears on the ticket to their name in the GrowTix ticketing system. To do so, go to your confirmation page and click on the light blue button that says, “edit” next to the current name.
