I've grown quite a few of the NL99s, not the 100% C99 ... the NL99 is very bushy, real tight branching, very little spacing between calyxs, beautiful growing plant ... some I topped, some I didn't ... only made about 6"-8" height difference, when done after the 5th internode ... and, I liked the yield from the topped plants ... clone the hell outta her, she won't mind the cutting ... I had a bunch of young ones bite the dust from my g/f over-watering them while I was outta town for a couple weeks, but that is the only negative experience I ever had with NL99 ... I harvested my NL99 with about 10% amber trichomes ... (I get about 3-4 ounces of DRIED bud, I take just the primo colas ... my friend, Custom39, grew the 7+ ounce beauty pictured on Joey's NL99 webpage, by sitting his pots on a 30-degree angle to the floor, and rotating pot daily) ... cerebral, colorful, grinning high, not much body stone, very popular with others that tried her, lots of compliments ... the straight C99 should be even more 'head-high' ... you'll enjoy the ride :jointsmile:
