Critical mass, how is the potency?

I was Looking into mr nice critical mass and am reading a lot about its monstrous yield but that potency is lacking, is that true in your opinion or does it provide a huge harvest of potent buds? Also any crosses with critical mass that you may recommend?

No, it depends on the quality of the grow.
Poorly grown, the potency will be low. Well grown the potency will be excelent, trust me.
You can also look at Critical +, Channel +, Power Kush
All are the best yielders you can find and excellent body stone.

Its okay smoke.

Critial Jack is really nice, yields AND potency.
