roof growing?

This is my first time growing and I planted the seeds in a big pot with soil on top of my roof where it can get sun. I want to know if this thing is gonna grow, also I have a little problem, my pot is infested with ants.... will this effect my plant

Maybe. Read as much as you can from the GROWFAQ

You just might get caught there, buddy.

with my experience the fuckers cut seedlings in half.
