Eh, that's true of most plants. If you want it really successful, you gotta put in the work. Honestly though, just start growing and see how it goes. If it's legal, you have very little to lose but time and whatever fertilizer you used. Goes bad, start again...
I think the easiest way is to plant the drughemp seeds in a fallow field or a forest a few miles away from where you live. It's a weed and grows well in lack of strong competition. Obviously, don't use lights, only use the sun. Harvest it several weeks later in the middle of the night using night vision goggles so nobody knows you're there, don't touch it until then.
