Hey, Im currently growing PPP and White widow. All are from seeds , feminized, from Nirvana.
I am running 2 400 watt mh for the growing section and 4 hps 400 watt for my flowering area.
What I have noticed is that the PPP is really forgiving, compared to the White Widow in nutriant dificiancy, or overnuting, or other mistakes on my part. I am growing in soil, not hydro. All nutes are organic.
I took clones just befor I switched to flower and got 100 % success so far, I am going to try cloning from flowered plants as an experiment, just to see what happens, in a couple of days from now.

Those PPP will get large, fast. As they are predomonantly a sativa. I let them get possibly too big befor switching them ( sixteen inches ), and I may end up with monsters on my hands, even though I topped and fimed them. I put them in flowering 15 days ago, at 14 to 16 inches and measured them this morning, at 20 to 26 inches. next run I will switch to flower when they are 10 or 12 inches. Maybe even less. I am also going to try an outdoor grow with the same strain, I have no idea how that will work out.

I havent had a chance to try any yet as this is my first grow of PPP.

Happy growing!
