I've been growing Nirvanas PPP both indoors and outdoors. The only thing that I can add to the above coments is that you must make sure that your plant is fully ripe befor you harvest it. ( get a magnifying glass and check the trich's)

I picked some a couple of weeks early ( about 5% amber ) and was disapp:thumbsupinted in the results. The plants that I matured to full ripe kicked a*s.
This is a very good strain for the begining grower, as well as the more experienced. Easy to grow, forgiving if you mess up on the ph, nutes, etc.
and easy too clone.

I bought 20 seeds, feminized, a year ago. and have chosen 1 plant in particular to take my clones from. The Nirvana strain showed very little variation from seed to seed so my plants all stayed about the same size throughout the grow. I simply chose the most hardy plant to take my clones from.

I grew 6 indoors under 400 watt hps lamps, along with 5 white widow, in botanicare organic soil, in 5 gal pots. And harvested about 2 lbs ( cured weight) from the PPP plants. I let them get about 14 to 16 inches in veg befor flipping them to 12/12. They all streached to above 4 ft. in flower.
All had been topped or fimmed in veg. ( no real difference in bud production between the two ).

As a side note: I also re-veged all of my harvested plants and grew them outdoors with good results. This was an experiment, which I may or may not try again).

I plan on continuing growing this strain as this is my "bread and butter" strain and can heartily recomend it.
