More than likely it is going to smell..............bad!!! Odor control is a must, especially if you don't want the neighbors calling an exterminator because there is a "rogue skunk" terrorizing the neighborhood.
It's almost impossible to identify strain by picture alone. It could be virtually anything but it sure does look purty!
It depends on the variety but most likely without smell control it will. I grew cheese last summer in an old detatched garage without a filter and I could smell it from 50 feet away. I'm in my house with 12 plants and a 6" active air filter and fan and at 9 weeks and there is almost no smell. Get a fan and filter if you are worried about it.
fish tank supply store or a store like walmart's fish aisle, but make sure you get activated carbon(pretty sure thatsall u can get at walmart but im not positive)
As I mentioned before, it's almost impossible to tell strain from a picture. Here's a good example of what I'm talking about. I had some seeds I got from a highly reputable seed bank from a highly reputable breeder. I planted all 10 of them and ended up with 8 females! Awesome luck huh? Anyways, they were all the same strain but no 2 plants looked exactly alike. In fact once they matured the buds all looked kind of different. Now they were all dank as hell and there were some similarities, but each plant was a unique individual. Plants inherit traits from the parents. The observable traits are called phenotypes. No 2 plants grown from seed, even the same 2 parents, is going to be exactly the same. This is why you simply can't tell what strain bud is by looking at pics. Hell you can't always tell by smelling it or smoking it. And you mentioned yourself that it may be photoshopped.............or it could be some other strain altogether. Either way it looks beautiful so I say "Who cares what strain it is?" Enjoy it!
