It can but it's gonna take alot more light to do it my first grow I just finished I went the route of more veg more bud and it is not necisarily true it takes a lot of light to penetrate, and without light from all sides the more potential budsites are starved for light by higher bud sites and it just isn't really worth it. Indoor it's pretty hard to handle huge plants and impossible IMO with cfl, or at least have it pay off.
