I think White widow is a 60/40 sativa dom plant.
It doesnt yeild alot,but what it does yeild is mind blowing.
My first indoor plant I grew was "Bro's grimm white widow."
I wish I had it now!!!
But the Buzz was terrific,I grew it for years.
Out of the three strains listed I would grow Great white shark,its out of the white widow family,and yeild good,also with a great Buzz.
Northern lights is a good strain,and G13 is also,hell why not get all three?
If I was growing,I would be seeking the "Apollo 13," line.
Its GREAT weed,and the gorilla arm pheno can get heavy yeild.
Peace,
