I think he should find another hobby if 2 weeks is going to take up too much of his time, this sport is all about patience.
I think he should get bag seed, he is going to kill anything he gets guaranteed, too much water, too many nutes, has to harvest early because he ran out of time so the bud will suck, etc etc etc, you name it, it will take him several grows and a couple years to get a handle on it guaranteed.
If he goes with Nirvana he has a 30% chance of finding a keeper, if he waits 2 weeks and gets a decent brand he has a 100% chance of finding a keeper.
It doesn't matter he will kill it all I can see it happening already.
