I have one of those just going into the 9th week of flower today. Yes, it is very bushy and there are buds everywhere, but so are the White Widows that I have in the same bubbler. I vegged them all under about a dozen 30 and 42 watt CFLs and the nodes on all of the plants were only like 3/16" apart. I never topped anything and the NL x BB is all a fairly uniform height with buds everywhere. The buds are not large and they don't seem to have filled in and I don't know if they will. I am starting to see some amber trichs, so the plant will probably come down this week -- at least if more turn amber this week. While the buds aren't large and aren't very tight, there are, as I said, a LOT of them.
I did a couple of test smokes at week 7 and 8 and I agree with Mr. Greenie. When I took my first three hits, I was disappointed because I thought nothing was going to happen. After a few minutes, though, I realized that I had a big grin on my face and I was typing at like 200 mph (and not making ANY errors). I was like a typing fiend. But when I had to drill down to find the right folder for this set of documents, I just stared at my screen trying to figure out what I was doing. I finally gave up because I just didn't care anymore and went to talk to my wife. I sat in a chair and giggled at her for like a half-hour. She just sighed and rolled her eyes. That made me giggle even more.
The high -- and keep in mind, this is with almost no amber trichs -- was very much in the head and right behind the eyes. Absolutely no paranoia or anxiety, which is something I have to be kinda careful of because some weed can give me rushes of anxiety or panic.
Anyway, if you want to see a pic of my NL x BB at about 7 weeks in flower, I have a thread in this same sub-forum called something like, "Almost week 7 in flower -- How do they look?" There are only three plants in there and the NL x BB is all the way on the left. Well, there are actually 4 plants, but one is a NL x BB in soil that is separate and in the background on the right. That plant burned to a crisp when it was a baby because I let it touch a 42 watt CFL. I had heard about how not hot those lights were and didn't realize that 42 watt CFLs get *very* hot. The plant was nothing but solid brown except for the stem and a tiny pin prick of green at the center. Over the next couple of weeks, that green center began to grow and then it began to look like a plant again. This won't mature at the same time so I am going to keep her going for another month or so after the other plants come down. The plant is stunted, but hey, it is filled with buds too. The NL x BB must be pretty hardy and forgiving if it can recover from being burned to toast.
So, to sum up, I wish the buds were larger and tighter. All of my grow is just for me, so I am not at all worried about bag appeal, but still... On the other hand, I will get a lot of smoke from this one plant and I am very happy with the strong and euphoric high. I'll be interested to see how the high develops as more of the trichs turn amber and it gets a proper cure.
