how much direct sun

I got a couple of plants outside. I live in the south so the sun is pretty hot this time of year. Will I need to limit their time in the sun? Will they grow just as well if I just left them in the shade?
Thanks

you'll want as much direct sunlight as possible,the more sun the better and bigger they grow

Yeah leave them in the sun. They will get used to it...remember its a weed your growing
