The Auto-Flower with the hight?

Hey, everyone I just needed a quick opinion. Getting ready to get seeds for my first LED grow. A friend had recommended auto-flower strains. I did my research and they look pretty optimal for first time growers. My only problem is my grow tent is 63' inches tall and most of these stains only get as high as 24-28 inches. What stains can I look at the get a little taller?

BTW: I am growing with a 240w led, and two plants in a tent that is 16 deep, 32 wide, 63 tall.

i have an advanced seeds biodisel mass thats like 4 and a half feet tall right now

Nah! Why not just SOG it. Why the need to full the rent. I'm outside and mine are only like 2ft and buds gathering thick and fast and I planted 50 days ago. Only 25 days left maybe. Autoflower is about short bushy from my experience
