If you start plants in a dome or just indoors and move the plants strait outdoors, the plants arent used to the high intense light the sun puts out so they will sun burn. If you sprout the seeds outdoors in the sun and not under a dome, you lower the chances of sun burn. Also a dome will strech the plants stem from the dirt to the first set of leaves a bit and the plants will be week do to no moving air in the dome compaired to the natural winds of the enviorment that the plants will be grown in. This is just a simple grow to get people started. And also I have started growing pot at age 12 and befor that my father grew for many years and he is the one that showed my the old tricks so I know what Im talking about. Now just let me do this step by step grow for these people to help them out, OK? Thanks.
