Great W.S. is a real strain, and the other ones I haven't heard before.

I heard of Haze, all kinds of haze. Originally a 100% sativa but there are dozens of diff. crosses of it these days.

Strawberry could be Strawberry Cough, an 80% sativa. It is quite possible to cross any 2 different strains on cannabis, so Strawberry Haze, if it's real, should be a damn near pure sativa, but slight indica traits.

Then again, lots of people like to pull out fancy names from their ass, but like you said, this person is growing it, and growers usually know what they're growing as compared to dealers, who just gets the finished product.
