First time growing veggies from seeds, and I want to make sure I treat them right. I’ve had them in this little greenhouse container and they went absolutely bananas after I added a seedling heating mat. I didn’t expect them to grow so fast so I’m feeling a little unprepared ????

I have a grow light, I just need some pots. Will they be okay another day in the container? It looks like they’re reaching for the light so I worry they’re not going to get enough and die.
