the ak gives a bigger yeild but you can get the same amount with the white russians if your an experienced grower. A simple solution is to just get both strains and see what one fits you best. The white russian is a bit stronger smoke kind of indica dominant and the ak is more sativa dominant.
Nah bro, it's exactly the opposite.
AK-47 for potency - long lasting intense high
White Russian for yield and more bag appeal
Not that the WR is weak, but it most definitely dilutes the high of the AK-47. White Widow has a nice buzz, but it doesn't last as long as AK-47, and it doesn't taste as good either. Both are good choices though.
Lowryder sucks!
