marijuana will thrive under at least 10k lumens per foot on the plants. anything less and it wont be optimal, anything more and youll get yourself some serious buds but have to watch your heat!
10k is usually just a good number to go by i feel though. More importantly is getting light to all of your plant. If you have a really bushy full bred indica or something weather you have 10k or 50k lumens on your plants, only those top colas and buds get that light because the rest is shaded. for this reason alot of growers put in secondairy lights that hang below the level of the top colas to provide light to the undergrowth and stimulate bud production to areas otherwise that would produce just popcorn
