Black Gold Auto | First time grower

June 8th, 12:00 i put my little seedling in the water, i used some collected rainwater for this. I use a heater in the room to keep it warm and a steady tempurature. On June 9th, 14:00 i noticed that my seed popped his root out. I swiftly used a plastic cup with 3 holes in the bottom for now, and used regular soil, topped with a plastic bag for the humidity. When a little plant decides to show i plan on keeping it inside for ~ 7 days before transfering it to a bigger pot outside. This is my first time growing so if you have any golden tips, greatly appreciated!!!
