What next?

I am currently growing some mdanzig blueberry, from the research I have done I have learned that it will be a potent great tasting bud. However it is not supposed to be a great yielder. I would like to offset the blueberry's with something that could possibly take longer but have large yields. And I would prefer if it was available feminized. Any input would be greatly appreciated.

Thanks

personally i would get white widow. or THC Bomb. You can get it here:
THC Bomb Marijuana Seeds

Commercial growers are starting to use it because of its high thc and short plant height.
