I've heard northern lights is pretty easy to grow, but my first grow were bag seeds. I don't recommend it seeing as you can buy strains from seed banks and get plants with good genetics but if your growing from a bag seed you can end up with different strains and usually slower growing plants. And when you buy seeds from an online you can choose feminized seeds which 99.9% of the time turn out female so you don't have to remove males and waste a month watering something you aren't going to use, especially if you paying for nutrients, soil, etc.
